VELO3D expands two senior executives based in Europe
California-based metal AM leader VELO3D announced that it is expanding its team in Europe with the addition of two senior executives to support the growing global demand for industrial metal 3D printing. In addition to Jon Porter, the UK-based European Business Development Director of VELO3D, who is leading the expansion of the company’s commercial activities in Europe, Managing Director Dr. Jose Greses will split his time between Germany and Spain and Xavier Fruh, Sales Director, will be based in France. Dr. Greses holds a doctorate in laser welding and was most recently at GF Machining Solutions after 14 years at EOS, while Fruh, who has an MBA and a master’s degree in electrical engineering, spent the last four years in business development in Europe with AddUp.
“The expansion of our presence in Europe is in response to the new demand for the highest possible levels of metal AM quality that only Velo3D offers – as well as design freedom that unleashes innovation and competitiveness for industries like aerospace, oil and gas can improve. and alternative energies, ”said Benny Buller, Founder and CEO of VELO3D.
Etihad Engineering, EOS and Baltic3D partnership for research and development
Etihad Engineering, the Middle East’s largest provider of maintenance, repair and overhaul services for commercial aircraft, is working with industrial 3D printing solutions provider EOS and Baltic3D, one of Northern Europe’s largest industrial AM centers, on a research and development project called “ FDM. together and the applicability of SLS industrial 3D printing technology in the serial production of aircraft interior parts. ”Baltic3D will use EOS’s aerospace-qualified laser sintering technology, as well as other powder bed AM solutions, to print over 2,000 material coupons on the EOS P396 printer to press. These samples will be tested in accordance with aviation standards at Etihad Engineering’s flammability laboratory in Abu Dhabi, and Etihad will also provide its technical reports and analysis upon completion of the tests. The aim is to build a comprehensive test and manufacturing dataset to help aerospace engineers confidently develop part designs for 3D printing.
“As the first MRO airline in the Middle East to receive EASA approval to design, manufacture and certify 3D printed cabin parts, we are excited to support Baltic3D and EOS,” said Ahmad Rajei, Acting Vice President Design, Engineering and Innovation, Etihad Engineering. “The launch of this R&D initiative is in line with Etihad Engineering’s position as a leading global player in aircraft construction and as a pioneer in innovation and technology.”
Desktop Metal qualifies 316L stainless steel for shop systems
Moving on to the materials news, Desktop Metal, which also went public this year, has qualified and launched 316L stainless steel for use in its metal binder jet shop system. The company’s materials science team confirmed that the metal material, which is characterized by high ductility, corrosion resistance and excellent mechanical properties at extreme temperatures, meets the MPIF 35 standards of the Metal Powder Industries Federation when printed and sintered using the shop system. It is a great choice for applications in demanding environments such as surgical tools, the marine industry, petrochemical processing and more, and now that it is available for the shop system, Desktop Metal customers can low-cost, high-volume production of 3D printed 316L stainless steel enjoy steel parts such as custom spray nozzles, closures for medical devices, and a bevel that houses the dial and movement.
“The introduction of 316L for the shop system is part of an aggressive and comprehensive materials roadmap to expand our AM 2.0 portfolio and address a rapidly growing range of use cases for our printing platforms. We are fully focused on developing ways for our customers to produce parts competitively with conventional manufacturing, and we look forward to expanding our binder jetting technology to meet this need and key existing and emerging killers -To address applications for 316L in the marketplace. ”Said Jonah Myerberg, Co-Founder and CTO of Desktop Metal.

Study of ceramic 3D printing by Joshua Pearce
Dr. A major advocate of 3D printing and all open source issues, Joshua Pearce has moved from Michigan Tech to the Department of Electrical & Computer Engineering at Western University in Canada and continues his work in 3D printing. Dr. Pearce recently informed us about a study entitled “SiOC (N) Cellular Structures with Dense Struts by Integrating Fused Filament Fabrication 3D Printing with Polymer-Derived Ceramics” that he published with some colleagues from the University of Trento in Italy. As he explained in an email, ceramic 3D printing is typically low-resolution and inexpensive, or very costly when used on large medical or aerospace projects, using Lulzbot’s open source desktop 3D printer Manufacture of fully dense, high resolution ceramics.
“In our approach, preceramic polymers can be molded in the polymer state and then pyrolyzed to make different types of ceramics,” wrote Dr. Pearce in his email to us. “With this technology, cellular ceramics can be produced. Our study reports on the novel production of cell ceramics with a two-step process using PDCs. The first cell structures are 3D printed with Fused Filament Fabrication (FFF) made of thermoplastic polyurethane and impregnated with preceramic polymer polysilazane. Second, the pyrolysis of the impregnated structure creates a self-similar ceramic cell structure. The influence of 1) catalysts, 2) curing environment and 3) optimization of the pyrolysis sequence for the formation of cell ceramics with fully dense SiOC (N) struts is examined systemically. The resulting custom ceramic components can withstand operating temperatures of 1500 ° C and can be made on a desktop 3D printer for less than 5% of the cost of competing processes. The ceramic material proves to be biocompatible and promotes rapid cell adhesion. Finally, it is shown that the cell activation in the early stage on the SiOC (N) structure can be tuned by adjusting the porosity with this 3D printing in order to mimic the bone tissue geometry for bone regeneration. “

Phone scope & photocentric case study
Finally, digiscoping company Phone Skope prints its bespoke smartphone adapters in 3D using Photocentric’s LC Magna solution, which includes the large format LCD LC Magna printer and post-processing units. Phone Skope worked with manufacturing service provider Merit3D to quickly model and create adapters without expensive, tedious molding -processing units. The two-piece design of the adapter system is interchangeable and works with most optics and smartphone combinations, and only one LC Magna printer platform can accommodate up to 52 enclosures, depending on size. By working with Merit3D to use Photocentric’s AM technology, Phone Skope has saved thousands of dollars in equipment costs and reduced the time it takes to develop a new case model from a few months to a few weeks.
“The manufacturing of Phone Scope has been challenged by the fast-paced nature of the market as its products have had to be compatible with a large number of new phone models introduced each year. In order to make a compatible digiscoping adapter for a particular model of phone, a mold had to be created for each new case, and there was always the possibility that the phone itself did not have commercial success. This meant Phone Skope had to choose between the models it would support and create for the shapes to maintain viability, ”explains Sally Tipping of Photocentric. “3D printing was a great solution to this problem and gave Phone Skope the flexibility to bring a wider variety of adapters to market quickly without the cost of making additional molds. Phone Skope products are known worldwide for their precision and durability. It was therefore also important that these properties are retained without compromise. “
