3D Printing News Briefs: October 3 2017

It’s the first 3D Printing News Briefs of the month, and today we’ll be starting off with a little 3D printing material news, followed by a 3D printed military project, 3D printed aircraft engine parts, and some business news to round out the day. i.materialise has introduced a new finish for its polyamide material, a group of Marines at Camp Lejeune are testing out a small, 3D printed  remote-controlled aircraft, and Safran’s newest helicopter engine features 3D printed parts. Royal DSM announced a collaboration between Somos and 3D Hubs for 3D printed tooling, while a new report says that 3D printing could cut out a quarter of world trade by 2060. Finally, a pitch deck has raised $30 million in Series A funding for Cazza Construction.

New Waterproof Finish for i.materialise Polyamide Material

Belgium-based 3D printing service i.materialise has launched a new finish for its Polyamide (SLS) material – now you can order 3D printed objects that are waterproof, in addition to the many other colors and finishes available for the material. The material, only available in white to ensure maximum quality, can be used for small series, as well as complex and functional models, and adding the waterproof finish, recommended for decorative use, to 3D printed objects will make them more impermeable. The maximum size of models that can be waterproofed is 300 x 300 x 300 mm, and the diameter above internal channels needs to be at least 6 mm, so you don’t block them with the sealing agent.

“To obtain the waterproof finish, the model is 3D printed using the same procedure as standard Polyamide prints,” writes i.materialise employee Aura in a blog post. “Once the Polyamide piece is done, we process the surface of the material with an aqueous solution to fill small pores and close the outer surface to make it water-repellent.”

“We apply the solution either manually, or by dipping the part, depending on the design. As with most post-production processes, extra labor cost is required and therefore, it will add  two more working days to the standard lead time when you order your waterproof object on  i.materialise.”

US Marines Testing 3D Printed SUAS

At Camp Lejeune in North Carolina, US Marines with the 2nd Marine Division have been testing a 3D printed remote controlled craft known as an SUAS, or small unmanned aerial system. Engineers and technicians from the US Army Research Laboratory had Marines from multiple military occupational specialties take the 3D printed SUAS out for test flights to demonstrate how convenient and useful it is when compared to current systems the military uses, as well as learn its practical applications and capabilities in the field. The 3D printed SUAS can be quickly modified for different kinds of missions, and a catalog has been created by researchers so service members can choose the SUAS that best fits the objectives of their mission and download the necessary information to 3D print the craft, which can be created, printed, constructed, and ready to go in one day.

Eric Spero, a team leader in the vehicle technology directorate of the US Army Research Lab, said, “At this point we are focusing on intelligence, surveillance and reconnaissance missions.  We have different cameras such as an infrared and a day camera; there are different things we can do like stream the video to systems or a heads up display and record it for later viewing.”

Safran’s Newest Helicopter Engine Features 3D Printed Parts

Speaking of aircraft, Safran Helicopter Engines is introducing its new turboshaft Aneto-1K engine, which features some 3D printed parts. The engine will be used in the Leonardo AW189K helicopter, and offer 28% more takeoff power, along with a 25% increase in power-to-weight ratio compared to other engines of the same size. Several 3D printed parts were used in the Aneto-1K engine, including parts that the company calls “critical” in the compressor’s stators.

According to Leonardo, using the new engine will allow the AW189K helicopter to “respond to market demand, particularly in hot-and-high conditions.”

Certification of the Aneto-1K engine is scheduled for the third quarter of 2018, with the helicopter’s entry into service happening around the same time.
