We start with some awards news in today’s 3D Printing Briefs, as both Additive Industries and 3DEO scooped big prizes at the TCT Awards. Also at TCT 3Sixty, Roboze finalized an agreement with Matsuura Machinery Ltd. Next, we’ll move on to standards, as ASTM International is working on a new one that will help the use of powder bed fusion technology in the manufacturing of medical devices. Speaking of the medical sector, Sanwa is bringing 3D printing to the field of dentistry in Japan. Finally, Australian researchers are using crossed light beams to control chemical reactions in a next-generation 3D printer.
Additive industries win TCT transport app award
At the recent TCT Awards, Dutch metal 3D printer manufacturer Additive Industries won the TCT Transport Application Award for its work on a tooling nozzle for the Volkswagen Tiguan, in addition to being a finalist for the TCT Hardware Award – No -polymer systems. Working with Additive Industries, Volkswagen achieved a 650% reduction in manufacturing costs for the nozzle, which was used for the automated filing of a rope into the vehicle chassis flange. The automaker used the MetalFAB metal 3D printer to make the nozzle in one piece, instead of two, from 316L stainless steel – a cheaper option than its original titanium alloy.
Also at the TCT Awards, which are produced by the TCT Group in conjunction with the TCT 3Sixty additive manufacturing event in Birmingham, high-volume metal 3D printing company 3DEO won the TCT Consumer Product Application Award. The company, which launched its new Saffron platform and patented Intelligent Layering technology earlier this year, won for a 3D-printed production razor it made for Blackland Razors. The double-edged safety razor, called Era, has been 3D printed in stainless steel and is fully customizable.
Roboze and Matsuura Machinery finalize the agreement
The awards aren’t all that happened at the recent 3Sixty TCT. At the show, Roboze announced that it had finalized an agreement with Matsuura Machinery Ltd to be its UK representative. Matsuura offers fully engineered manufacturing processes to OEMs, contractors and SMEs, such as automated multi-axis CNC machining solutions and metal and plastic 3D printers. Today, Matsuura has expanded its 3D printer portfolio by adding Roboze’s large format ARGO 500, its industrial super polymer system. The printer will be on display at the Matsuura showroom in Coalville.
“Roboze 3D printing technology has proven its ability to transform manufacturing and be a valuable addition to the arsenal of progressive manufacturing companies. Adding Roboze to our product range makes us a formidable player in the UK additive manufacturing supply chain, delivering cutting-edge technology, creating components from a myriad of materials,” said Roger Howkins, managing director of Matsuura Machinery Ltd. “We look forward to customers seeing the Roboze product range installed and demonstrating their prowess at our brand new Additive Manufacturing Center in Leicestershire in the near future.
New PBF standard guide medical device manufacturers
ASTM International has a new standard, developed by its additive manufacturing committee F42, which will offer guidance to medical device manufacturers on the reuse of powder in powder bed fusion AM processes. The new F3456 standard explains what ASTM calls the “seven broad reuse patterns” that will offer manufacturers relevant information for regulators who want to better understand how powder reuse patterns can affect medical device performance. This is actually the first standard developed by the F42 Subcommittee on Medical and Biological Standards.
“Medical device additive manufacturing manufacturers and regulators will find this new guidance useful. The guide can also be useful for additive manufacturing manufacturers to broadly describe their reuse process to customers without having to give specific information about the manufacturing process,” said Matthew Di Prima, Fellow at ASTM International.
Japanese Sanwa Dental adopts AM technology
Tokyo-based Sanwa Dental is bringing 3D printing to dentistry in Japan, as it announced the successful adoption of additive manufacturing in its Thai dental lab. Sanwa believes that if the Japanese dental industry sees wider adoption of the technology, more patients would have easier access to high-quality dentures, implants and other dental applications, paving the way for the future. expanding the use of technology in the region. . The new printer installed by Sanwa was supplied by the manufacturer Profeta, based in Nanjing Zijin, China, and specialized in metal 3D printers for dental laboratories.
Sanwa explained some of the many benefits of additive manufacturing, including creating designs that would be nearly impossible with normal molding methods. One example was the design and printing of dentures with thinner and smaller metal frames, so that the wearer could speak more easily and clearly. Another benefit has been to reduce the number of steps to create these titanium prosthetic frames from ten to just five, resulting in an increase in productivity.
QUT publishes research on next-generation 3D printers
A team of researchers from Queensland University of Technology (QUT) in Australia have published a paper on their work using crossed beams of light to control chemical reactions in an advanced material capable of 3D printing entire layers, rather than single points at a time. According to Dr. Sarah Walden of the interdisciplinary research team at the QUT Center for Materials Science, the precision that light offers to start a reaction makes it an excellent tool for activating chemical processes. She explained that in this case, two light beams of different colors are used, causing a reaction only where the two intersect, and ARC laureate Professor Christopher Barner-Kowollik noted that two of these activated materials by color are very rare. He said the team’s research aims to prove the ink’s viability for the next generation of 3D printers.
“We use one color of light to activate one molecule and the second color of light to activate another molecule. And where the two light beams meet, the two activated molecules react to form a solid material,” explained Dr Walden. “Normally, in a 3D printer, the inkjet moves in two dimensions, slowly printing a 2D layer before coming up to print another layer on top. But using this technology, you can turn an entire sheet into two dimensions and print the entire sheet at once.
