Andy Wen Loong Liew has submitted a thesis, ‘Laser-based 3D printing using bessel beams for tissue engineering applications’ to Nanyang Technological University. Exploring a new technique for bioprinting, Liew studies the use of Bessel beams in connection with regenerative medicine techniques, and he also compares the benefits of traditional techniques. Liew cites the benefits of … Read more

Chinese researchers are looking further into the uses of titanium in bioprinting, outlining their findings in the recently published ‘Mechanical behavior of a titanium alloy scaffold mimicking trabecular structure.’ Five different unit cells were used in this study as the authors experimented with creating new trabecular structures via electron beam melting. 3D printing has already … Read more

UK researchers from the Department of Engineering, University of Cambridge are studying new systems for construction materials, outlining their results in the recently published ‘A novel biomimetic design of a 3D vascular structure for self-healing in cementitious materials using Murray’s law.’ Some of the most interesting scientific breakthroughs are founded in nature as researchers are … Read more

Leading off our 3D Printing News Briefs today, the Wohlers Report for 2020 has been released. Moving on, Nanofabrica has achieved excellent results of direct rapid soft tooling with 3D printing. Two more interesting 3D printed projects we’re covering are ACCIONA’s 3D printed concrete bus stop, and HP’s 3D printed artwork in honor of Women’s … Read more

3D printing is used often in the automotive sector, and many recognizable names, from Volkswagen and BMW to Ford and Toyota, are adopting the technology. German automobile manufacturer Porsche, which specializes in high-performance sports cars, SUVs, and sedans, has turned to 3D printing multiple times in the past to make components for e-drive powertrains and turbo … Read more

Dutch chemical company Royal DSM has announced a partnership with Youngstown, Ohio’s Juggerbot 3D to develop 3D printers and materials for pellet-based manufacturing. This represents greater momentum toward the adoption of pellet-based additive manufacturing (AM), which is sometimes considered to be the future of material extrusion 3D printing technologies.  While DSM is already well-known within … Read more

Last year, a scientific team in Warsaw, Poland, bioprinted the world’s first prototype of a bionic pancreas with a vascular system. Led by clinical transplantation expert and inventor, Michał Wszoła, the specialists seek to introduce 3D bioprinting of the bionic pancreas to clinical practices worldwide in just over three years. The work, conducted at Polbionica, … Read more

In our last article in our series covering 3D printing in a climate-disrupted world, we discussed the myriad problems associated with polylactic acid (PLA), the most popular plastic and bioplastic for desktop 3D printers. Here we’ll break down one of the more interesting alternatives to PLA that is emerging on the market. Polyhydroxyalkanoates (PHAs) are … Read more

In the first article in this series, I laid out a consumer consumption-driven world where our needs are never quite met by things. Our needs are now mistranslated into a desire for objects that we do not yet have. Yet when we get that t-shirt, pair of headphones or gadget it never fills the needful … Read more

Just a few years ago, the FDA approved the first Molybdenum-99 (Mo-99) to be produced domestically without the use of highly enriched uranium (HEU). This medical isotope helps radiologists detect bone decay, heart disease, and some types of cancers that are difficult to find, and in 2018, the US Department of Energy’s National Nuclear Security Administration … Read more

SmarTech has published its latest report, Market Opportunities for Additive Manufacturing in the General Industry and Tooling Sector 2020-2029, which will add a great deal of clarity to some of the stories we’ve recently covered related to the adoption of 3D printing in the general industry and tooling sector. One of the most important insights … Read more

International researchers explore methods for removing contaminants in their recently published ‘Nuclear wastewater decontamination by 3D-Printed hierarchical zeolite monoliths.’ Focusing on the radioactive cationic species, 137Cs+ and 90Sr2+, this study brings greater exposure to the need for selective removal of radionuclides. Harkening back to the disasters that occurred at Chernobyl in 1986 and the Fukushima Daiichi plant … Read more

Dayton Phillip Street recently presented his doctoral dissertation, ‘Enhancing the Macroscopic Properties of Parts Printed via Fused Filament Fabrication by Incorporating Nanoscopic Additives,’ at the University of Tennessee. With a focus on creating additives for fused filament fabrication (FFF), Street strives to improve the ‘inferior performance’ of 3D printed polymeric materials. Polymers are widely used … Read more

Thed BOTT 1000 Morlaco is the one of the first superbikes’s to have its body and other components produced with 3D printing technology. This superbike was developed by Bottpower, a Spanish high-tech motorsport engineering company located in Valencia. The company is managed by David Sanchez, a mechanical engineer who has experience on, not only motorbike … Read more

Nonprofit standards development organization ASTM International, which develops and publishes technical standards for a range of industries, materials, products, services, and systems around the globe, has signed a memorandum of understanding (MoU) with Underwriters Laboratories (UL), another nonprofit which works to advance its mission of public safety through discovery and application of scientific knowledge. The … Read more
