In today’s 3D printing briefs, a proposed ASM standard will work to control the cleanliness of metal powder feedstock. Meltio announced an official business partner in Japan, Biohm announced a new suite of services, and Siemens NX added intelligence-driven design to its Xcelerator portfolio. Finally, Atherton Bikes breaks down the manufacturing of its 3D printed frames, and Farsoon details how it 3D printed a TPU helmet for a bobsled team competing in the recent Winter Olympics.
Proposed ASTM Standard for Metal Powder Raw Materials in AM
First, the ASTM International F42 Additive Manufacturing (AM) Technologies Committee is working on a proposed standard that will help users control the cleanliness of metal powder raw materials used in AM by performing assessments of reused powders and unused; the goal is to ensure the quality of 3D printed components. Powder properties can deteriorate through the introduction of contamination, such as when the material is handled and processed, and especially reused, which can lead to defects and inclusions in the final components The F42 committee encourages those interested in help develop the standard, especially technical experts who have studied the contamination of metal powder used in AM and/or have experience in cleanliness assessments.
“The proposed standard will help manufacturers and users of metal powder raw materials used in additive manufacturing to identify appropriate methods to detect and quantify different types of contamination. The guide will define and classify typical contamination that may be present in metal powder raw materials,” said Aneta Chrostek-Mroz, Fellow of ASTM International, Research Engineer at MTC.
Meltio Announces Nihon Binary as Business Partner in Japan
Laser metal deposition technology manufacturer Meltio has announced new business partners left and right, in North America, the Benelux region, Brazil and Europe, and now it has another to share. The company announced that Nihon Binary is now its official business partner in Japan, and will distribute and support Meltio’s metal 3D printing solutions in the Japanese metal AM market.
Nihon Binary has been in business for over forty years and has worked with the 3D printing industry for over a decade, providing products to customers in education, industry and research . The Japanese company will help drive Meltio’s growth in the domestic metal additives market and create business opportunities for the company’s process, built around safe and affordable welding wire, in collaboration with universities, centers technologies, industry, robotic integrators and machine tool companies.
Biohm launches services to integrate biomimicry
Committing to a climate-positive future, research and development-driven biomanufacturing company Biohm has introduced a range of services to help companies integrate biomimicry, promote regenerative practices and embed circularity . The first service offered by the company is Climate Positive Resource Management, which uses your resource data to calculate carbon flux and generate a complete picture of your company’s current environmental impact. Then, Biohm can demonstrate how materials development can be used for decarbonization efforts, and even lead to a feasibility study to see if your waste stream can be validated as a feasible feedstock to create mycelium materials.
Another service is Mycoremediation, which helps break down synthetic and man-made waste, like plastic, using fungi. Biohm’s fungal strains can degrade, detoxify and decarbonize problematic waste streams to turn the harmful end-of-life process into a regenerative one. Biohm also offers bio-based materials development and product development services that address the need for decarbonization, and finally nature-inspired design services, which allow customers to create a bespoke part from regenerative materials. After evaluation, the company will generate a few concepts, then evolve the design by prototyping and testing with potential circular materials, and finally fabricate and install your piece, bringing nature into the space and hopefully inspiring practices. regenerative.
Siemens NX software release adds intelligence-driven design
In addition, Siemens Digital Industries Software recently launched the latest version of its NX software, which is part of the Xcelerator portfolio, and this version offers advanced technologies, including advanced simulation, machine learning and artificial intelligence, which help users achieve their design and engineering goals faster. The release has responded to over 1,200 customer enhancement requests for more innovation, and updated NX software highlights include a new NX Topology Optimizer, which helps create parts based on functional requirements and design space; the Design Space Explorer, which combines generative engineering with design space exploration to help automatically optimize a design against multiple goals; and the ability to use Simcenter 3D simulation from Siemens to optimize truss structures.
“With each new release of NX, Siemens pushes the boundaries of what product development systems are capable of. Our move to continuous releases of NX is proving incredibly popular with our community, allowing us to deliver cutting-edge features faster than before. This means providing access to new tools and technologies so they can be applied to our customers’ design, engineering and manufacturing challenges to help them overcome them faster,” said Bob Haubrock, Senior Vice President product engineering software, Siemens Digital Industries Software. “We continue to improve the core tools our customers rely on every day, with over 1,200 customer enhancement requests delivered in this release.”
Atherton Bikes 3D printing of mountain bike frames
Famous and award-winning ATV racing siblings Rachel, Dan and Gee Atherton aren’t just stars in a race. The British trio have also started their own company, Atherton Bikes, which uses 3D printing to create their frames. The company began working with Robot Bikes, which combined carbon fiber tubing with 3D-printed titanium lugs, and also collaborated with UK-based Renishaw to build its first 50 bikes. Now the brand is moving into full-scale production with frame kits and custom builds direct to customers, and offers four models, including a World Cup-proven DH bike and a 150mm trail bike.
At first, Atherton sent its 3D printing jobs to Renishaw, but after a successful crowdfunding campaign, the company purchased its own 3D printer, built by Renishaw. Each titanium powder print takes 15-18 hours, and there is a 24/7 live stream for staff to view if needed. The parts are sent for heat treatment still on the base plate, and the supports are then removed with grinders and pneumatic hammers, before the parts are sent for final machining. The carbon fiber tubes are cut to length and the frame is dry assembled, with the lugs 3D printed, in a jig. Finally, a mechanic will assemble the bike to the buyer’s specifications.
3D Printed TPU Bobsled Helmet for Winter Olympics
Finally, Farsoon Technologies and Wanhua Chemical Group teamed up with China’s Bobsleigh Helmet Research and Development Team, led by Associate Professor Li Nan of Dongguan University of Technology, to create a new helmet that the team will be able to use during the Winter Olympics last month. Maximum racing speeds can reach up to 160 km/h, so safety is paramount in competition. Performing well at high temperatures, Wanhua Chemical’s specialized TPU material was used to create the bobsleigh helmet liner, and it was printed on Farsoon’s Flight 403P SLS dual-laser 3D printer, which can produce two liners in a single build in less than eight hours. The team used 3D scanning to collect the data needed to customize the helmet liner mesh design for each athlete, and each mesh structure includes multiple layers and buffer zones with varying levels of hardness, in addition to the distribution structure of different densities in areas with higher collision frequencies. , to better absorb any collision damage. In addition, the helmet, with its 3D printed TPU liner and carbon fiber shell, is also lighter and more comfortable.
“With Farsoon’s high-speed dual-laser Flight ® technology, we are able to achieve a custom design and an accelerated manufacturing process. We are also impressed with the performance of the new generation of custom helmets, as the impact resistance of the helmet liner is increased by more than 40% compared to the international standard,” Li said. “It is also inspiring for us to use a 3D-printed lattice structure to produce other protective sports parts, which provides new opportunities for upgrading helmets, armor and other protective gear.”
