“Our expansion into the United States is an important milestone for BCN3D, as it indicates that the company is now fully capable of meeting the needs and demands of BCN3D’s partners and customers in the region,” said Xavier Martinez Faneca, CEO of BCN3D. “The new New Jersey hub will provide great business opportunities there starting in 2022, enhance our customer relationships and represent BCN3D’s commitment to environmental sustainability as we consolidate larger shipments for more customers with a logistics center closer to them in North America.

Wematter launches the Gravity 2022 SLS 3D printer

3D printer manufacturer SLS Wematter showcased its flagship Gravity 2021 system at Formnext 2020, and recently released the latest version of the user-friendly printer. With improved repeatability and fit for global expansion, the new Gravity 2022 is built to withstand harsh environments, able to print with more materials that can withstand fire and ESD, and allows users to scan every package of individual powder so as not to load the wrong kind. The company started participating in international trade last year, and its SLS printers are used in places with varying temperature and climatic conditions. that’s why the 2022 Gravity includes individual cooling systems and better component selection. Because Wematter values ​​sustainability, several components of the Gravity 2022 have been replaced to reduce its energy consumption by 25%, and the printer’s proprietary electronics have been redesigned to adapt to a higher volume context. high and be less affected by the global shortage of semiconductors.

“Thanks to the annual model changes, Wematter has the opportunity to highlight the strengths of its products after consultation with its customers. This year, we have chosen to prioritize working time,” Robert Kniola, Founder and CEO of Wematter, said of the new features in Gravity 2022, continuing that “…Wematter has eliminated one of the stages of mandatory inspection between each start of SLS construction work. We have also introduced lighting in the chamber to simplify powder removal and removal of 3D models. »

Wematter Gravity is suitable for a rental system, or produced as a service, which means the hardware can be purchased with a pre-made subscription support system.

Cubicure enables industrial serial printing of polymer parts

Cerion’s new printing concept enables additive mass production of industrial-grade polymer parts.

Another recently launched 3D printer is the new Cerion at scale by an Austrian company Cubicure GmbHwhich enables industrial serial 3D printing of polymer parts and is already being used by pilot customers. Cubicure has spent the last few years developing the Cerion to cover the entire digital manufacturing process, and this system has a scalable printing concept, with a rotating resin carrier film and a moving printhead, very different than most typical lithographic AM methods, as it does not use material vats or resin baths. The Cerion relies on Cubicure’s hot-melt lithography technology, so it has access to a variety of photopolymers, and parts are meant to be printed on the system’s one-meter-by-30-centimeter platform with reproducibility and an optical precision of 50 x 50 μm2.

“This is the essential advance in the industrial upgrading of lithographic printing processes. In this printing process, the material supply and detachment of the printed polymer layers from the carrier film is scalable,” explained Cubicure Managing Director and CTO Dr. Robert Gmeiner. “Many factors in the construction process, such as process forces, are now decoupled from room geometry and building platform occupancy. Even the width and length of the printing platform no longer have an influence on the performance of the process. After three decades of stereolithography, an industrially scalable process has finally been found.

Interdisciplinary team dealing with 3D printed affordable housing

Auburn University professors are part of an interdisciplinary research team seeking to develop composite materials from waste for use in 3D printing affordable housing. From left to right are Auburn’s leading scientists, Maria Auad of the Samuel Ginn College of Engineering, Sushil Adhikari of the College of Agriculture, and Brian Via and Maria Soledad Peresin of the School of Forest and Wildlife Sciences.

A interdisciplinary research project between Auburn University and its partner institution the University of Idaho studying the feasibility of create affordable housing with 3D printing, thanks in large part to $3.9 million in funding from the National Science Foundation’s Research Infrastructure Enhancement Program. According to Brian Via, a professor at the Auburn School of Forestry and Wildlife Sciences, only half of the American population has affordable housing. The aim of the project is therefore to create environmentally friendly materials, based on waste or natural sources, which can be used at 3D printing houses. The team is currently working on developing bioresin as a raw material for 3D printing, as well as converting biomass into nanomaterials and chemicals to make the resin more durable.

“Recently, the United States has been moving towards adopting mass timber buildings as a first-generation material to reduce our carbon footprint. However, advanced manufacturing can help utilize more biomaterial waste from forest resources that can then be 3D printed into housing or building components,” said Via, who is also the principal investigator of the research project.

“We will manufacture 3D printed wall panels that can be used in the construction of housing and buildings. This will allow for precise construction in a manufacturing environment using durable materials that can be shipped to the job site. Thanks to bio-based polymers and fibers, we can 3D print construction components that allow end-of-life recycling.

Using technology to help people hear again

With hearing loss, which can be caused in many ways, either the eardrum is perforated or the tiny hairs inside the cochlea are damaged. Scientists from the Wyss Institute at Harvard University found a solution to the first problem, while researchers from China’s Huazhong University of Science and Technology (HUST) attack the second; both teams state-of-the-art technology used like 3D printing to find their solutions. The PhonoGraft biofabrication platform, developed by Harvard researchers and acquired by Desktop Health, is a 3D-printed biocompatible graft implant that provides a scaffold for natural eardrum cells to regenerate and restore hearing in people with a perforated eardrum. The implant, 3D-printed from synthetic polymer-based ink, mimics the shape of a natural eardrum and has already entered commercial production, with the founders scrambling to get FDA clearance for their innovation.

The HUST team has designed a prototype, battery-free hearing aid that can be implanted in the ear and translate sound waves into corresponding electrical signals, essentially simulating healthy cochlear hairs without having to rely on a power source. external. Scientists have created a sponge material that uses piezoelectric (compression) and triboelectric (friction) qualities, and created the prototype sensitive acoustic sensing device using this material. When tested in a model ear, the prototype produced a frequency of 170 hertz, which is within the range of most adult voices.
