Kraiburg TPE has actually performed substantial tests to analyze the viability of its thermoplastic elastomers (TPEs) for use in additive production (AM). The tests have shown that almost all of the company’s TPEs can be processed with exceptional outcomes using merged deposition modeling (FDM) on devices from French 3D printer manufacturer Pollen AM.

Pellet additive production system can manage soft materials such as TPEs.

Additive manufacturing is making huge strides in changing the world of the production industry. Thanks to the fairly simple and tool-free equipment of the devices, even advanced parts can be printed quickly and in the really location where they are required.

” Due to physical restrictions, many classic 3D filament printers are not suitable for processing soft TPEs. In addition, it’s just possible to draw fairly minimal conclusions from prototypes made of unique 3D printing products in relation to the efficiency of basic injection molding or extrusion compounds,” states Dr. Thomas Wagner from Product Management EMEA at Kraiburg TPE. “The obstacle we dealt with was to exactly examine the prerequisites for fused deposition modeling of soft TPEs. In order to discover an ideal option, we had to learn to separate the technical restrictions of the printers from those of the materials.”

Shimadzu ´ s AGX‐V Series testers combine world‐class efficiency with ideal operability and boosted safety functions for both QC and R&D applications. User-friendly software application improves productivity while enabling easy production of techniques.

The pellet additive production (PAM) system from Pollen AM showed to be the ideal innovation. The existing series of PAM granule printers produce incredibly detailed surfaces even with very soft TPEs and have the ability to process up to four products at the same time. In this way, typical hard-soft multicomponent composites made from TPEs in combination with plastics such as polypropylene (PP), acrylonitrile-butadiene-styrene (ABS) or polyamide (PA) are also possible.

” Our PAM printers guarantee the quickest possible house times to avoid impacting the particular advantages of soft elastomers,” explains Didier Fonta, Head of Operations at Pollen AM. “This likewise makes sure excellent peel strength, especially for multi-component applications with thermoplastic elastomers in the low Shore firmness variety.”

Tests performed collectively by Kraiburg TPE and Pollen AM have actually led to persuading prints featuring mechanical homes that achieve up to 50 percent of the values shown by comparable injection moldings, depending on the procedure specifications.

This indicates that the provided TPE compounds are thoroughly selected and processed, so the technology is suitable for producing both presentation samples and also functional models and is therefore able to minimize the expenses of developing brand-new applications.

Given that almost all thermoplastic elastomers that Kraiburg TPE has in its portfolio are possible materials for direct processing on PAM granule printers, no special substances are needed. Additionally, all functions of the products, especially their adhesion possibilities on various thermoplastics, are preserved in 3D printing with PAM granule printers. Residues that may arise during production can be recycled in local waste streams.

” Due to physical constraints, the majority of timeless 3D filament printers are not appropriate for processing soft TPEs. In addition, it’s just possible to draw relatively restricted conclusions from prototypes made of unique 3D printing materials in relation to the efficiency of basic injection molding or extrusion substances,” states Dr. Thomas Wagner from Product Management EMEA at Kraiburg TPE.

The current series of PAM granule printers produce exceptionally detailed surfaces even with really soft TPEs and are able to process up to four materials at the same time. Because nearly all thermoplastic elastomers that Kraiburg TPE has in its portfolio are potential materials for direct processing on PAM granule printers, no unique substances are needed.

Ahead of LMT Lab Day 2020 in Chicago today, 3D Systems is introducing a new optimised 3D printing workflow for orthodontic designs.

The additive production leader is set to reveal a brand-new digital production option integrating its NextDent 5100 3D printer, NextDent Model 2.0 material and 3D Sprint software, which is stated to facilitate the high-precision, vertical stacked printing of orthodontic designs.

The solution will enable oral laboratories and centers to produce 30 orthodontic models in one print or 120 models in an eight-hour duration (size and geometry reliant). The key to this latest offering is a brand-new auto-stacking function within 3D Sprint which supplies one-click automated preparation and positioning of models on the build plate including wise nesting and proprietary assistance structures. The function is stated to provide high precision, reduced material usage and labour, and simple break-off supports.

” We’re delighted to reveal the most current innovation for 3D Systems’ Digital Dentistry Solution,” Menno Ellis, senior vice president and general manager, plastics, 3D Systems, told TCT. This makes it possible for printing of 30 orthodontic designs in less than 2 hours and is offered to all customers as part of their 3D Sprint license.

The function is expected to be readily available for all NextDent 5100 users in early Q2 2020. The news demonstrates 3D Systems continued financial investment in its oral portfolio following the acquisition of Vertex-Global Holding B.V., consisting of the NextDent materials brand name, back in 2017.

More just recently, the business secured 510(k) clearance from the FDA for its NextDent Denture 3D+ material, which when utilized in conjunction with NextDent C&B MFH, is stated to provide a last denture that is 90% cheaper to produce in 75% less time than those developed via standard techniques.

3D Systems will display its portfolio of 3D printing technologies at this year’s TCT 3Sixty event being kept in Birmingham, UK between September 29th and October 1st, 2020.

Formlabs has actually revealed a partnership with Germany-based BEGO, a manufacturer of prosthodontics and implants for the oral industry. Together, the partners intend to bring short-lived and irreversible 3D printed crowns and bridges to the marketplace for dental applications.

Through the collaboration, Formlabs oral consumers will have access to BEGO’s series of corrective products for dentistry, enabling them to 3D print momentary and permanent crowns for clients directly. This capability– of having the ability to produce dental restorations using a fully digital workflow– is anticipated to lower expenses and turn-around times, resulting in much better patient care.

” Directly printing short-lived crowns and bridges are one of the most searched for applications from Formlabs clients,” described Dávid Lakatos, Chief Product Officer at Formlabs. “By partnering with BEGO and leveraging their 130 years of dental experience, we will have the ability to not only address this requirement, but take it an action further by providing products for permanent crowns.

We are thrilled to see how this collaboration can continue to advance the dental industry and conquer the major challenges laboratories and dental professionals face as digital dentistry ends up being a standard for client care.”

BEGO has actually been active in the dentistry world since its starting in 1890. The business’s creator, Dr. h.c. Wilhelm Herbst pioneered making use of unique filling gold for treating cavities. Today, the company’s innovative spirit endures.

For example, BEGO has actually been developing 3D printing products for the oral market for over twenty years now. With the Formlabs collaboration, it is solidifying its commitment to additive innovations in dentistry.

Formlabs has actually also been a key player in the dental AM section. In fact, the business recently revealed the development of a dedicated Dental Service System in addition to the launch of a new 3D printer for dental applications, the Type 3B.

” We could not be happier to partner with Formlabs, particularly at this time, where digital dentistry is reaching a breakthrough,” said Axel Klarmeyer, CEO of BEGO Dental. “It spent some time and a great deal of effort and dedication of all involved people to be able to provide to the marketplace a completely verified workflow for final remediations. This partnership highlights BEGO’s leading position in the dental 3D printing materials market.”

Thanks to the cooperation, dental experts using the Formlabs 3B and Form 2 3D printers will be able to leverage BEGO’s resins to 3D print temporary crowns and bridges in addition to irreversible single crows, inlays, onlays and veneers.

The mix of BEGO’s products and Formlabs’ 3D printing technology is expected to significantly decrease the expense of producing crowns and bridges while also enhancing product quality.

Amongst the advantageous homes of BEGO’s 3D printing products are low discoloration and aging rates, low plaque accumulation, and high comfort because of very little temperature level of sensitivity. The materials are also offered in a series of shades to best match the client.

In our vehicle focus last month, we spotlighted many of the automakers using additive production for production today, consisting of German automotive huge Volkswagen.

Today, one of Volkswagen’s leading brands Audi has actually revealed more about its use of 3D printing. A team of 3D printing specialists at Audi’s Böllinger Höfe center is dealing with Berlin-based software company trinckle to establish a software platform for creating tools.

The goal of the partnership is to develop a user friendly design software application that will enable Audi employees to easily design a custom-made tool without comprehensive style or 3D printing experience.

According to Audi, the brand-new software gets rid of time-consuming steps in the standard style procedure, including manually shaping designs in CAD programs. The brand-new platform apparently has the capability to cut design times for brand-new tools down by 80%.

Waldemar Hirsch, task supervisor and the head of the 3D printing group at the Ramp-Up and Analysis Center at Audi Böllinger Höfe, said: “Our software makes the procedure of producing pre-assembly components almost entirely automated. That permits us to make the essential tools rapidly and flexibly and to react to specific demands from the coordinators or our associates on the assembly line.”

The design software and resulting 3D printed tools are playing a crucial role in the production of the Audi e-tron GT, the brand’s very first automobile to utilize 3D printing as a recognized part of its series production workflow.

The automobile, which is arranged to come off the assembly line later on this year, will count on optimized assembly tools made with additive production technologies. Audi’s 3D printing group is working closely with its process and assembly planning and pre-production teams for this task.

” Collaborative design from an early stage allows optimizations to be made previously in the process too,” included Hirsch. “This implies that all the necessary tools will currently be offered and adjusted to the specific requirements when production of the e-tron GT starts.”

One of the 3D printed tools developed for the Audi e-tron GT’s production is for the pre-assembly of air-conditioning compressors and cooling lines, which need to be perfectly aligned. Generally, the assembly needed a minimum of 2 people to carry out, today with the 3D printed pre-assembly fixture and an incorporated clamp, the components can be put together with exact positioning.

The dedicated style software application established by Audi and trinckle is helping the automaker to accelerate its digitalization and take tangible steps towards accomplishing wise factory status. Today, the browser-based software is being used by Audi Sport GmbH at the Böllinger Höfe site, but the company eventually plans to roll it out more broadly.
