3D Printing News Briefs, March 6, 2021: CGTrader, Lore, BAM – 3DPrint.com

3D model provider CGTrader, # 1 in today’s 3D Printing News Briefs, raised over $ 9 million in a recent funding round. Olympian Colby Pearce has teamed up with the new company Lore to bring a bespoke 3D printed road bike shoe to market. Finally, researchers from Germany published a paper suggesting that natural source material like the powdered waste produced by boring insects like termites could be a more sustainable 3D printing material.

CGTrader Announces Series B Funding Round

CGTrader founders Marius Kalytis and Dalia Lasaite

The 3D modeling market CGTrader, founded in 2011 by its current COO Marius Kalytis, announced that it has raised a total of $ 9.5 million in a Series B funding round. Finnish VC fund Evli Growth Partners led the round with former investors LVV Gruop and Karma Ventures, and Mikael Hed, former CEO of Rovio, also invested and joined CGTrader as chairman of the board. The international company with offices in Lithuania and New York City is a major provider of 3D content. With 1.1 million 3D models and 3.5 million 3D designers serving 370,000 companies like Staples, Nike, and Microsoft, CGTrader also claims to be the largest 3D model provider. With the help of this new funding, CGTrader plans to consolidate its position and further develop its platform. It is also considering investing in the automation of 3D modeling, asset management processes and quality assurance.

“As well as being widely used in the professional 3D industry, 3D models are a more convenient and affordable way to create amazing product visualizations for e-commerce,” said Dalia Lasaite, CEO and Co-Founder of CGTrader. “With our ARsenal corporate platform, it is up to ten times cheaper to create photo-realistic 3D graphics that cannot be distinguished from photos.”

Launch of 3D printed custom bike shoes

American Olympic cyclist and bicycle mechanic Colby Pearce is a national champion and record holder and has long focused on the fit of shoes for both himself and his customers. Now he’s working with a company called Lore to bring a 3D-printed custom road bike shoe, the LoreOne, to market next month. A spokesman for Lore, who employs many people who have worked in design and engineering at big brand names like Nike, Apple, Tesla, and Puma, said the shoes will initially be made in California and sold directly to consumers, although it is planned to do so The sale of the LoreOne through bicycle mechanics is set to 2022. Although not many details are yet available about the new shoe, such as: For example, how much it weighs and how much it costs, we know the hardshell shoe is supposed to be more efficient due to its carbon monocoque design – a structural system where the outer skin of an object bears the load. In addition, the LoreOne is 3D printed using scans of a driver’s feet.

Pearce said, “The technology, materials, design and manufacture are light years ahead of anything else on the market.

“The way the athlete works with the shoe is groundbreaking and the grip is unparalleled. The Lore Project is three great steps away from any other shoe on the market. Prepare for your head to explode as your feet feel a real power transfer for the first time. The LoreOne shoe will forever change the way you interact with your bike. “

3D printing of wood particles from boring insects

a) European house borer (Hylotrupes bajulus) adult larva (above) and adult beetle (below); b) the sieved food (in a particle size fraction of 45 to 100 μm), which is generated by larvae and used for 3D printing.

A research team from the Federal Institute for Materials Research and Testing (BAM) published an article with the title “In search of biological raw material: 3D printing of wood particles from house drills and dry wood termite damage”. about their work with wood processed by the European House Drill (EHB) and dry wood termite insects as a natural, novel 3D printing raw material. Frass is the technical term for the fine, powdery waste that these insect larvae leave behind during feeding. Through their research, the team found that the quality of these materials differed greatly in terms of processability for binder jet 3D printing and that neither were suitable for making ready-to-use structures due to their poor mechanical strength. However, these naturally available raw materials are more environmentally conscious when it comes to 3D printing for scientific materials science and could instead be used as preforms, especially termite-fed raw material pellets.

“Small particles were used that were produced by the dry wood termite Incisitermes marginipennis and the EHB Hylotrupes bajulus during the feeding of timber. Frass is a powdery material of particularly consistent quality, which is essentially biologically processed wood mixed with wood residues and faeces. The filigree particles flow easily and enable wood structures to be built up in layers using the binder jetting printing process. The quality of the powders produced by different species of insects was compared along with the processing steps and properties of the printed parts. Dry wood termite damage with a Hausner ratio HR = 1.1 with ρBulk = 0.67 g / cm3 and ρTap = 0.74 g / cm3 was perfect for the deposition of evenly packed layers in 3D printing, ”the researchers wrote.
