First in today’s 3D printing briefs, Particle3D underwent a rebranding, and a team of researchers developed a way to 3D print and preserve tissues in sub-point conditions. freezing while keeping them viable for transplantation. Massivit expanded into the defense industry and Alloyed 3D printed a copper cooling plate for use as a liquid cooling system in data centers. Finally, a personalized version of Aectual’s 3D printed Weave panels serves as a canopy for the Dutch House of Representatives.

Particle3D changes its name to Ossiform

Danish medical technology company Particle3D, which won our AMS startup competition in 2020, has completed a rebranding campaign and is now called Ossiform. The slogan “We Print Bone” remains, but the company has grown and matured over the past two years, and as the launch of its first 3D printed bone implant for human use approaches, this rebranding brings Ossiform closer to the marketing. The old name of the company came from its patented powder particle-based 3D printing method, and its new name represents the efforts to provide bespoke 3D printed bone implant products, with multiple benefits for healthcare providers and patients, which look like real bone. Now that Ossiform has launched its new name, logo and website, it can continue to focus on preparing its products for the $ 4.8 billion bone implant market and introducing its P3D scaffolds. in laboratories.

“It has been such an exciting journey the past two years with Particle3D, and I am proud to be part of the rebranding of the company by bringing Ossiform to life and paving the way for the launch of the first P3D Bone,” said Thea, CEO from Ossiform. Wulff Olesen. “Now the name emphasizes what we do – We Print Bone – and according to plan, we’re set to launch later this year.”

Researchers 3D printing and tissue preservation in cold weather

Thousands of people die each year while waiting for organ transplants, which is why research on bio-imprinted organs is so important. However, traditional and 3D printed organs are only viable for a few hours and should be kept cool during transport; too cold or too hot, and cells can be damaged, which means the organ is useless. But a team of researchers from Harvard Medical School, École de technologie supérieure (ÉTS) and McGill University believe they have a solution and reported on their new technique, called cryobioimpression, in a recently published article. The team developed a bio-ink containing various sugars and dimethyl sulfoxide that can freeze safely within milliseconds after printing on a cold plate at -20 ° C, so that the 3D tissue structure is preserved, without the fear that it will fail. loses its complex shape or viability. . They demonstrated that with their technique, 3D printed fabrics could be safely frozen for at least three months; once thawed, the tissue cells were still healthy and functional.

“Historically, you have to print a handkerchief and use it right away. This limits the ability of these constructions to be stored and / or transported between locations, ”said study co-author Y. Shrike Zhang, biomedical engineer at Harvard University. “In 2017, we started to think: ‘can we design ways to bioprint and store tissues simultaneously? “”

Massivit enters the defense market with a strategic collaboration

Large format leader Massivit 3D has entered the defense industries market for the first time, signing a strategic collaboration agreement with Kanfit, an Israeli manufacturer of metal and composite products for the defense industries. aerospace, aviation, defense and medical devices. Kanfit manufactures parts and assemblies for some of Israel’s major aerospace players including the Israel Air Force, the Defense Ministry and others. As per the agreement, the award-winning Massivit 10000 3D printer will be installed at the Kanfit factory for customer beta testing and will be used to produce molds for manufacturing composite parts. The Massivit 10000 operates using the company’s Cast-in-Motion (CIM) technology, and preliminary sales of the system continue ahead of its official launch; Kanfit’s order is the 14th placed for the large format printer.

“We are delighted to sign the first such agreement, for the strategic collaboration with Kanfit, one of the most important defense manufacturers in Israel,” said Erez Zimerman, CEO of Massivit. “This agreement is an important step in the achievement of the objectives and the commercial strategy of Massivit.”

3D Printed Alloy Copper Cooling Plate

The result of a merger between OxMet Technologies and Betatype in 2020, Alloyed delivers next-generation performance for metal components through its alloying and process design technologies, and its 3D printed copper cooling plate, which has was on display at Formnext 2021, was recently featured in Additive Manufacturing Media’s Cool Parts Show video series in Cincinnati, Ohio. The plate was designed for use in data centers and, since it is a liquid cooling system, it can significantly reduce power consumption compared to more conventional air cooling methods. 3D printing is a good choice for making these cooling plates because it is able to achieve more complex geometries with greater functionality and fewer parts, which equates to easier installation and less maintenance. Copper can be difficult to print due to its natural reflectivity and the high thermal conductivity of the fused part, which is why Alloyed used copper powders from its partner JX Nippon Mining & Metals (JXNMM), which are manufactured with a new surface treatment to keep electricity conductivity and porosity low on 3D printed parts.

“The success of the copper cooling plate presented at Formnext is due to the combined expertise of Alloyed and JXNMM,” said Enrique Alabort, Co-Founder of Alloyed and Director of Alloyed Japan. “The materials developed by JX allow Alloyed to use its proprietary Engine® and Architect® software to produce the complex high-fidelity geometries and lattice structures of the cooling plate. Alloyed specializes in producing components with fine characteristics and can produce thin walls up to an average thickness of 190 microns, and its design expertise for AM allows it to make the most of the design freedom afforded by the Alloyed. process. This expertise is clearly illustrated in the design and production of the copper liquid cooling plate.

3D printed circular canopy for the Dutch House of Representatives

Zecc Architecten, who won the ‘Dutch Architect of the Year 2020’ award, designed a temporary location for the lower house of the Netherlands parliament, known as the House of Representatives or Tweede Kamer, while that its normal complex is being renovated. The company, which seeks elegant material solutions and technical components, decided to design a unique circular canopy for the building and created a customized version of the woven panels 3D printed by Aectual, a Dutch design company that offers products architectural designs and 3D printed interiors. such as flooring, partition walls, sound diffusion panels, etc. Bart Kellerhuis, Creative Director of Zecc, spoke with Aectual co-founder Hedwig Heinsman about the role circularity and recyclability played in the design of the venue’s glass roof, which is supposed to be a temporary government building.

“Circularity and the intelligent use of materials were part of the design brief, and why Aectual panels can be shredded and reprinted in new products has also been a driving force behind your collaboration. The building transformation was designed with a long-term vision in mind, allowing flexibility, ”said Kellerhuis.

“… The columns are part of the building’s fundamental identity. They really carry the building, connect the roof and the ground and make it a whole. By making the columns sinuous and soft, we wanted to break with the rather square and square character of the building. And when we started looking for a circular material and an innovative approach to creating these soft surfaces, we quickly found ourselves at Aectual. There was an instant mutual click as the Aectual team speaks the architect’s language, which made it easy and fun to work together. This has really led to more quality; Together we designed the surface solution based on custom weave panels and the plan improved together.
