When different designers, businesses, as well as engineers consider product development, most of them look at prototyping coupled with mass production as the primary goal and objective. But there are certainly moments when low-volume manufacturing is an optimal choice for people who demand modest quantities of parts, ranging from hundreds to thousands. In this blog post, we major our discussion on the low volume manufacturing strategies with a careful analysis of the nature of low volume production.

When utilizing a prototyping manufacturing service such as 3ERP, customers can gain the capability to increase the number of products and parts they need, regardless of the look of the final outcome.

Background Check

Low volume production implies different things to a variety of people. Being experts, it translates into the delivery of different quantities (typically less than 1,000 units per month). But this is just a comprehensive guideline.

It all depends on the size of the parts, the geometry, coupled with additional factors therein. If the production department exceeds 1,000 units every month, it would be advisable to consider various processes that can be cost-effective.

Why Low Volume Production?

Typically, low volume production serves the following purposes:

• The replacement of parts is not available in the production process. These are usually parts needed for repair
• Low-volume production elements are often parts created after the prototype phase is complete. These parts are also known as the production parts. Basically, they are tools for refurbishment.
• The low-volume production elements are created typically created after the phase of prototype design.
• They offer a considerable bridge between a prototype phase as well as the high-volume phase, where usually, different parts shall be manufactured using hard tooling. On that note, some manufacturers refer to the elements as the pre-production parts.

In the world of plastic manufacturing, we have exhibited our ability to utilize low volume production at trade shows all over the country. We have also had the chance and privilege to meet customers who have visited our shop to inquire about the services we offer.

When we offer an explanation about building and producing prototypes and production tooling, coupled with the manufacture of low volume production parts, one of the most commonly asked question is what quantity exactly does our team consider low volume?

An easy and direct answer has always been under 100,000 units annually. But in the real sense, it really just depends. In many instances, customers approach us to develop high-quality production prototypes. Through utilizing the modular tooling system, consumers can grasp an added advantage of the affordable tooling prices. Immediately prototyping is done, some customers need an estimate of about 10,000 production parts.

Final Thoughts  

Our offer on low production volume has been providing an ideal solution for clients with different needs. Some start-ups happen to be searching for a cheap and low-risk method of introducing their products into the market. On the other hand, others are known for being million-dollar firms that need low yearly quantities of specialty as well as replacement parts.

We are experts in the plastic injection molding process. As a team, we customize everything to fit into the demands of our customers. We also produce prototypes coupled with end-use production elements in about 20 days or less. Our team of production makes good use of aluminum molds, which provide cost-efficient tooling coupled with accelerated manufacturing cycles as well as other useful stock.  What is plastic injection molding manufacturing?

Our plastic injection guidelines will assist you in picking the right materials for your production processes. So why choose this method for your project?

Several proto labs make good use of rapid injection because it is a technology-driven process that highly leverages automation. All too often, in these processes, CAD models are used in the production of vital materials via the milling processes. The molds are then fabricated straight from aluminum. Steel cannot be used in such processes. The entire process allows for the team in charge to enjoy having a faster as well as effective tooling. As experts in charge, we provide additional secondary services which play a great role in supporting your project.

Definition

By definition, the plastic injection molding process refers to the whole technique of melting the plastic. This process is in this case the raw material enough to be able to inject some pressure into the mold cavity, which ends up filling as well as solidifying in order to be able to produce the end product.

How Does It Work?

The manufacturing sector is vastly expanding, and more and more production ideas are coming up. So how does the plastic injection molding work? Usually, it all starts with the thermoplastic injection coupled with the injection process straight from the photo lab. This is a procedure that involves an aluminum mold.

The material used in this case is heated efficiently- far much more than basic steel. Therefore, it transfers a lot of heat more than how steel how can do it. It also does not need any form of cooling channels. This implies that the whole process is time-saving, even though cooling needs to be applied in order to monitor pressure.

Final Thoughts

Conclusively, the resin pallets will be loaded into a unique barrel where they can be melted and then compressed. They will then be injected into the runner system of the mold. In this case, resin, hot as it is, will be shot into the cavity of the mold via the openings.

Technically, the ejector at the machine will facilitate the removal of tough parts from the inside of the mold. And when completely run, the parts will be boxed and then shipped as the procedure demands. Being experts in this field, we can easily supply brass part inserts if you make your order into a particular specification. For most of your customers, this just implies that all too often, there is no requirement for additional purchasing and collaborating with the suppliers because we handle all the tasks for them. Our involvement in the processes eliminates the huge risks of delay straight from the other suppliers who can interfere with the process.

There is nothing easy about starting a new project that includes creating a new part or an entire product, even for the most experienced engineers and entrepreneurs. Sometimes, even creating a tiny bolt can take hours of meticulous planning, calculating, and drawing. 

On top of that, you have to figure out the actual forming process that will lead to the creation of the physical part.

Very often, that choice is between a CNC milling service and 3D printing. Here are some of the most important factors to consider when choosing between the two technologies.

Dimensional Accuracy

This is one of the most important factors to consider when choosing the best-suited technology. CNC machines can achieve accuracy of up to 0.01 inches, while the tolerance can range up to 0.005 in. 

On the other hand, 3D printer accuracy can vary from printer to printer, as well as on the used technology. For example, a desktop FDM 3D printer features an accuracy of 0.5mm, while with the industrial ones, it can be as much as 0.2mm.

If it is an SLS 3D printer, the accuracy will be in the range of +/- 0.3mm. If it is a metal 3D printer, the accuracy will likely be +/- 0.1 mm.

Design Complexity

Some parts cannot be manufactured with a CNC milling machine. If the part includes complex internal parts such as overhangs, then your only option can easily be 3D printing.

Production Cost

In both cases, the production cost is determined by factors such as the volume of the object, the material used, and the complexity.

In the case of 3D printing, you pay for the used material and the final volume of the object. 

If you opt for CNC milling, then keep in mind that the smaller the object, the less cost-effective it is. In most cases, it’s way more cost-effective to use CNC milling for a larger object.

Loading

Structural parts that will be exposed to continuous physical loads are mainly made with CNC machining. 3D printing is preferred for creating non-structural parts. However, by adding some fiber reinforcement, the part can gain significant strength improvement.

The Greener Option

From this perspective, a 3D printer is the greener option because it uses less energy, and practically there isn’t any waste. On average, CNC machines tend to draw way more electricity because of the cutting tools, and after the process is completed, there can be plenty of waste.

In Conclusion

The simple truth is that 3D printing is not cost-effective for larger orders. That’s not the case with CNC milling. At the same time, sometimes CNC can’t produce certain complex products, while a 3D printer can. 

So it is fair to say that each technology has its advantages, as well as limitations. Understanding them is the most important step in choosing the right technology.

Most people only relate LCD to electronic equipment or machinery, but what they do not know is that LCDs have a wide range of applications. 

If you are hearing the term ‘LCD displays’ for the first time or have no idea of what it is all about, not to worry! This article has got you covered.

LCD is short for liquid crystal display. They are flat panel or electronically manipulated displays that use a merger between polarizers and properties of liquid crystals that modulate light.

Wait, huh?

Chill. It isn’t as confusing as it looks. Simply put, LCDs are flat or electronic panels that use a liquid crystal as its primary operating substance. They can be found in smartphones, computer monitors, instrument panels, televisions, etc.

They radically replaced older technologies like the Light Emitting Diode (LED) and the gas-plasma displays, because LCDs enabled displays to be much thinner and smoother.

With that being stated, how do they apply in various fields and industries?

• Precision instruments: Instrumentation is a very important component of information technology. Therefore, there is a need for the invention of instruments and meters that can be used to control technological advancements. STONE Technologies produce these instruments that can obtain, gather, analyze and display given data, which then helps the engineer to fix the machine and make the needed corrections. These precision instruments are widely used in electrical systems.
• Civil electronics: Civil electronics (otherwise known as Civionics) is a field that combines both civil and electronics engineering disciplines. Its application is vast.
• The STONE display can be used with LCD drivers and STM32 to optimize coffee machine control
• Fingerprint Identification can be done using the TFT LCD module
• LCDs are visible in snack vending machines. When people use these machines, they must be properly maintained. Much care and attention should go to the touch LCD screen so that the lifespan of the machine will be enhanced.
• Beauty and Medicine: Most people have no idea that LCDs can be applied to the medical and beauty industries. Here are some cases:
• LCD display manufacturers used the STONE display screen to manufacture an oxygen monitor for health specialists.
• LCD manufacturers used the Arduino LCD and HMI created by STONE Technologies to regulate and display heart rate
• Board tutorial: A STONE LCD device is used to manufacture beauty devices.
•  Energy:
• The LCD manufacturer, STONE, uses HMI display technology to enable effective field solar charging.
• The touch screen TFT LCD modules are used to carry out various energy projects.
• The STONE Intelligent display can be used in systems such as EV chargers, fuel dispensers, etc. With this technology, it is possible to design the interface with a lot more information.
• Electricity equipment: LCD display manufacturers can use TFT display systems to control humidity, temperature, and other components of an electricity system. The TFT module is so powerful that it can work under tough conditions like low temperature, electromagnetic radiation, etc.

Press brakes are very important in various industries and that makes them necessary to understand. To successfully bend these materials with a press brake, one would require detailed information and understanding of just how the machine functions, what it does and how to maintain it. For those new to working with press brakes, important things you should know are explained below.

Various Types of Press Brakes

One of the most common types of press brake is the hydraulic press brake. However electronic press brakes are more common as well. These hydraulic press brakes are more common and have been around a lot longer. Another reason they are so common is that they are quite easy to use. This means that they can handle heavier workloads and are manufactured in various sizes ranging from 3000 tons up to 50 ft. length. Most of these press brakes are found in 100-300 ton range too, making this the most for thicker materials.

Unlike the hydraulic press brakes, electronic press brakes are new to the scene, however, this doesn’t mean they aren’t designed to suit your needs as they have quite attractive features as well. They require no hydraulic oil to work so the issues of oil leaks and other issues are not necessary to fix in the long run. They run with electricity and they usually come in small sizes.

CNC press brakes are an electro-hydraulic servo press brake that offers you more efficiency and precision. When you make use of a CNC press brake, all you need to do is input the numbers of the number of pieces plus the bending angle of each and that is all. It carries on from there and bends accordingly.

There are very important things to check and understand when handling a press brake. One of those things includes the press brake tooling. Knowing the tolerance of tooling aids you in the punch and dies to make use of it. You need tooling that fits the specifications of a manufacturer. It makes it easier to make the necessary adjustments.

Some common dies for press brakes include V dies which vary in depth, angle, and width. If your project requires multiple bends, they can achieve this.

Press brake tonnage is another important thing to know. An operator will need to understand all the loaf limits present so they don’t damage the machine. It is important to familiarize yourself with the tooling load limits, forming tonnage, sinking tonnage limits as well as centerline load limits. It is also important to know how to calculate them.

Usually, tonnage estimates are present from the manufacturer and in some cases, they are mounted on a machine. Charts present are for air bending only and can be exceeded 8 times for counting. However, you can’t exceed it for air bending because you wish to damage the machine, material, and tooling.

It is important to be familiar with drawings as well. They come with various information such as bend angles, inside radii, the dimension of parts, blank sizes, etc. In a case where the information is omitted, then the operator will be required to make changes. This is a lot easier with more experience but not the best situation for press brake operators.

The world of 3D printing is rather an exciting place full of DIYers, creators, craftsmen, engineers, entrepreneurs, and forward thinkers. It is a community of millions that share a passion for 3D printing. They love their 3D machines, and they can’t stop talking about them. 

In this article, we are going to talk about two 3D printers. This is not just another 3D Printer Comparison, but it will be about two 3D printers from the same manufacturer – Creality’s Ender 3 and Ender 5.

Ender 3 vs. Ender 5

Assembly

Ender 5 is much easier to assemble as there are only 20 screws. Furthermore, the instruction manual is impressively comprehensible. Each step of the assembly process is easy to follow, even if you are assembling your first 3D printer. The assembly time for experienced people is around twenty minutes. If this is new for you, then you might need 30 to 45 minutes tops. 

On the other hand, assembling the Ender 3 can take you two or three hours. That’s quite a difference as the Ender 3 has way more screws and assembly parts. 

The winner is clearly Ender 5.

Build volume

The Ender 5 build volume adds 50 mm in the Y dimension, and other dimensions are equal. This is one of the most notable differences between the two models.

Winner – Ender 5

Heated bed and hot end

Ender 5 comes with an MK10 hot end, which minimizes filament jams and clogging, whereas Ender 3 comes with the standard MK8 hot end.

Both Ender 3 and Ender 5 share the same heated bed. However, the magnetic PEI sheet of Ender 5 does not stump into the power supply, which is an issue with Ender 3. The stock Ender 3 still suffers from this problem, but it can be easily fixed by adding a PEI sheet.

Then there are the Uxcell bedsprings on the Ender 5, which don’t need too much leveling, at least as not as much as with the Ender 3 bed springs. Plus, the Uxcell bedsprings are way better in holding tension. 

Winner – Ender 5

Electronics

Ender 3 comes with a certified Meanwell power supply, while the Ender 5 has a generic one which presents a greater risk of fire or an electric shock. 

The Ender 3 features a v1.1.4 mainboard, while the Ender 5 still uses the obsolete v1.1.3 mainboard. The thing with the v1.1.3 mainboard is that it doesn’t include thermal runaway protection. 

Winner – Ender 3 (because of the mainboard)

In conclusion

Ender 3 has been a hit and is regarded as one of the most popular entry-level 3D printers in the world. People will keep on buying it, and its deserved glory won’t go away any time soon. Furthermore, Ender 3 has a massive community spread worldwide, which provides excellent support to anyone that buys and uses this excellent 3D printer.

But now we also have the Ender 5 which is a clear step forward from the Ender 3, as it should be. Pretty much all the issues of the Ender 3 have been addressed and fixed with the Ender 5. 

So yes, the Ender 5 is a bit more expensive than the Ender 3, but that’s the price for all those improvements and bigger build volume.

A 3D printer is a machine that is used to convert 3D designs into real objects. The 3D designs are made using a computer and then fed to the 3D printer in a language that it can understand before printing. The real objects are made either using liquid plastic or other components other than ink. Once the object is made, it is left to dry so that it can assume a solid-state. 3D printers come in a variety of types, like the Ender 3 3D Printer. Other types of 3D printers include powder, resin, and extrusion printers, just to name a few. In this post, we discuss DIY 3D printers.

What are DIY 3D printers?

A DIY 3D printer is a machine that comes in pieces that have to be put together. You can also choose to build a homemade 3D printer for a science congress or a contest of any other kind. Below are some steps that will guide you in the process of building a DIY printer.

Putting together a DIY printer

• The first step would be to acquire the necessary parts. Some companies provide a variety of parts needed in the construction of 3D printers. Amazon also sells a variety of 3D printer kits that may work perfectly in this case. You need an extruder, a hot end, a power supply, and PLA filament, just to name a few parts. You may also need the stationary materials to put the parts together; such equipment includes a screwdriver. Once you have all the necessary parts, you need to understand each part, its purpose, and where it goes.
• The next step would be to read the instructions for putting the machine together. Companies like Creality provide their clients with a kit as well as the instructions. You can also opt for a video tutorial as it provides a better guide.
• You can now start constructing the device with the axis. A 3D printer has three Axis (x, Y, and Z-axis which are used to control the movement of the nozzle left and right, the bed, and up and down movements of the nozzle, respectively.

• Once the axis is constructed, you can proceed to make the bed of the printer. Make sure that the bed is level because it may cause your objects to come out inaccurate during printing.
• You can now proceed to make the extruder, fixing the hot end and inserting the PLA filament.
• Once you have the machine fully constructed, you can proceed to wire the machine and get the most suitable software for the DIY 3D printer.

Bottom Line

Make sure to clearly follow the instructions when making, fixing or inserting each part on each step. Failure to follow the instructions to the latter may lead to irregularities when it comes to printing objects on the machine. Wiring the machine is one of the most challenging bits of making a DIY 3D printer. If you cannot hack the process, make sure to hire professional help. You can always go for a fully made 3D printer if you find DIY tiresome and challenging.

A molarity calculator refers to a viable tool used in the calculation of the mass concentration of a given solution. The system may also be used in recalculating the existing grams of a component per ml into moles. Typically, you can also easily calculate the total mass of a substance required to achieve specific molarity. In this blog post, we shall provide you with basic molarity definition as well as the formula used to calculate it. This time, we shall use a mass molarity calculator too.

If you would like to comprehend the topic entirely, then you need to learn the basic definition of a mole once more. You will also be required to read the main paragraphs based on the units of molarity, and the comparison between molarity and molality.

Other than that, we have prepared interesting examples of ideal examples of solutions coupled with a step-by-step learning process of how to end up with the perfect definition and calculation of molarity, usually concentrated in a solution. And at the end of this blog post, you will learn more about titration while making a quick discovery of how to calculate the molar concentration via titration. This can help you in carrying out your titration processes.

Take a look around.

 Even if you are just at home, resting on that couch, you shall realize that there are different objects around. Most of the materials are not really pure. They are made of mixtures. And as usual, mixtures are made up of a viable collection of various compounds. Sometimes, the total number of these elements can be pretty much high. There are times when they can be low. However, for as long as there is one element in the object, that is an ideal mixture.

For instance, juice in a glass, or just a cup of coffee and detergents- these elements are mixtures. But mixtures are not limited to liquids only. Gases, as well as solids, are also perfect examples.

In the world of chemistry, there are two different types of mixtures. They include:

Homogenous– In this category of fluids, the components are distributed across the combination. There is, however, one major phase of matter that can be seen. These phases are identified as solutions. They can occur in solid as well as gaseous states. Some ideal examples of such components are such as sugar water coupled with detergent and dishwashing fluids.

Heterogeneous– Elements of such a mixture are usually not uniformly distributed. They could be having different regions with properties.  Some samples of such combinations are generally not identical. Therefore, at least two phases will always be present in such mixtures. And in many cases, it may be possible to separate these masses. A couple of examples of such combinations are such as concrete and ice cubes.

Every mixture has a mole. This is the SI unit for measuring the total amount of substance in a product. Typically, the mole contains elementary entities. To find the total number of moles in a product, you need to use a calculator. That said, molarity is always expressed as:

Molarity = Concentration / Molar Mass

Take-Home

If you want to calculate the molarity of a substance using a calculator, then this is what you need to do.

• Select your preferred substance. Here, we could assume that the product is hydrochloric acid
• Find the exact molar mass of the substance. And in case it is hydrochloric acid, it should be = 36 g/mol
• You can now decide on the actual mass concentration of the substance you have. Here, you can input it directly. You can also fill in those boxes for mass as well as solution volume.

One of the most substantial elements of 3D printing is the capability to produce objects that typically can not be manufactured using any other existing innovation. One famous example is the GE Catalyst turboprop engine, where 3D printing enabled the combination of 855 parts into 12 assemblies, decreasing weight and simplifying the supply chain in the process.

Since of this, people accidentally bias their design toward legacy processes and away from technologies like 3D printing,” said Benning.

“New components of the style process will be presented into engineers’ roles– they will need to discover the mechanics of 3D printing to become professionals in the procedures to support functional functions throughout production.

New roles will likewise be developed, such as reverse 3D engineers, for instances when 3D printing is utilized to build replacement parts for products that have no digital equivalent,” stated Benning.

A shortlist of what design engineers ought to learn about 3D printing, according to Benning, consists of:

The new wave of style capabilities that enable the creation of formerly unimagined complex shapes along with durable prototypes and end-use production parts.

Believing beyond cost reduction and speed optimization for existing products. The “real capacity of 3D printing is recognized when engineers can incorporate the physics, software application, materials and imaginative thinking around 3D printing to develop products that can not be manufactured today,” said Benning.

In fast prototyping applications, understanding that 3D printing allows the physical realization of preliminary concepts in a low-risk procedure. “Essentially, you can ‘stop working much faster’ utilizing this technology,” said Benning. “Design modifications are simpler and discovering cycles are faster, so you can utilize that extra time to create better products.”

Informing budding style engineers and re-training employees to operate effectively in this brand-new environment requires a “holistic” approach that incorporates the supply chain, commercial engineering, materials science and production, according to Benning.

A number of training programs have been developed that impart the ability needed to move “from old thinking and take advantage of new, innovative ideas.” One such program, mentioned by Benning, has actually been established at Oregon State University (OSU).

“For example, Oregon State University trainees are using 3D printing to design and construct combustion, electric and driverless vehicles. It’s this type of hands-on experience that will “teach graduates how to believe in 3D, iterate styles and produce future ideas utilizing additive production,” stressed Benning.

Other universities must follow these examples and “construct out programs that promote creative, brand-new ways of developing and believing,” said Benning. The future of innovative manufacturing depends on it.

One of the most consequential aspects of 3D printing is the ability to produce things that typically can not be produced utilizing any other existing innovation. Because of this, people inadvertently predisposition their design toward legacy processes and away from technologies like 3D printing,” said Benning.

“New aspects of the design procedure will be presented into engineers’ functions– they will require to learn the mechanics of 3D printing to end up being professionals in the processes to support functional functions throughout production.

New roles will likewise be created, such as reverse 3D engineers, for instances when 3D printing is used to construct replacement parts for items that have no digital equivalent,” said Benning.

“For example, Oregon State University trainees are utilizing 3D printing to design and construct combustion, driverless and electric automobiles.

The online HTML CheatSheet website shoult be the first bookmark of every web developer. It is the best one-page resource to generate the desired markup.

Last week，we caught up with Paul Benning, the chief technologist for HP 3D Printing & Digital Manufacturing to get an idea of where additive production is headed in the future. Benning discussed that we’re headed for mixed-materials printing, surface areas development, more involvement from academic community, and higher use of software and information management.

Automated assembly with mixed products

Benning believes we will start to see automatic assembly with markets perfectly incorporating multi-part assemblies including combinations of 3D printed metal and plastic parts. “There’s not currently an incredibly printer that can do all things inherently, like printing metal and plastic parts, due to factors such as processing temperatures, nevertheless, as automation increases, there’s a vision from the industry for a more automatic assembly setup where there is access to part production from both tastes of HP innovation: Multi Jet Fusion and Metal Jet.”

While the medical market and just recently aerospace are included 3D printing into production, Benning also sees automobile makers as a future client for additive. “The auto sector is a terrific example of where automated assembly could grow on the factory floor.”

Benning sees a wide variety of applications that might integrate metal and plastics. “Benefits of an automated assembly for industrial applications include printing metals into plastic parts, building parts that are wear-resistant and gather electrical power, adding surface area treatments, and even developing conductors or motors into plastic parts,” stated Benning. “The industry isn’t ready to bring this innovation to market just yet, but it’s an example of where 3D printing is headed beyond 2020.”

Surfaces will end up being a location of development

Benning sees a future where information payloads for 3D printed parts will be coded into the surface area texture. HP has experimented with coding digital information into a surface texture.

He keeps in mind that the surface area coding could be checked out by, humans for makers. “One way to tag a part either overtly or discreetly is to make certain that both machines and people have the ability to read it based on the shape or orientation of the bumps. We have actually put numerous copies of an identification number spread throughout the surface area of a part so that it’s both widely evident and hidden.”

Benning sees this concept as p [art of the future of digital manufacturing. “This is one of our inventions that serves to loop our technologies with the future of parts tracking and information systems,” stated Benning.

Universities will present brand-new ways to thinking

Benning believes that academia and training programs can offer new thought procedures to free designers from old thinking and allow them to take advantage of innovations of the future. “3D printing’s most significant impact to producing task skills push the style side,” said Benning. “You have a world of designers who have been trained in and grown up with existing technologies like injection molding. Because of this, people inadvertently predisposition their design towards legacy processes and away from innovations like 3D printing.”

“To fight this, educators of present and future designers need to adjust the idea procedure that goes into creating for production given the new innovations in the area,” said Benning. He likewise thinks new software application style tools will assist designers to make much better use of 3D printing in manufacturing.

Software and information management is vital to the 3D printing future

Benning believes advancements in software application and data management will drive better system management and part quality. This will then result in better client results. “Companies within the industry are creating API hooks to construct a fluid community for partners and clients,” said Benning.

HP is starting to use information to allow ideal styles and optimized workflows for Multi Jet Fusion factories. “This information originates from style files, or mobile phones, or things like HP’s FitStation scanning innovation and is applied to make production more effective, and to much better deliver individualized products purpose-built for their end clients.” The goal of that individualized production can support custom-made products build with mass production manufacturing strategies, leading to a batch-of-one or mass personalization.

“The industry isn’t all set to bring this technology to market just yet, but it’s an example of where 3D printing is headed beyond 2020.”

Benning sees a future where data payloads for 3D printed parts will be coded into the surface area texture. “3D printing’s biggest impact to manufacturing job skills lie on the style side,” stated Benning. Because of this, people unintentionally bias their design towards legacy processes and away from innovations like 3D printing.”

He also thinks new software style tools will direct designers to make better use of 3D printing in manufacturing.
