Key components, such as a side camera cover and attachments for the ventilation/heating system, were swiftly designed, and produced using INTAMSYS technology. The collaboration extended to the FUNMAT PRO 610HT, INTAMSYS’ large build volume printer, crafting Stella Terra’s front light housing with precision using PC-ABS. The printer’s sizable build capacity allows for the creation of large-scale parts tailored to diverse performance requirements. PC and PC-ABS, chosen for their high printing quality, mechanical strength, and heat resistance, cater to specific needs. PC excels in impact strength, while PC-ABS offers a refined surface finish and compatibility with metal plating. This thoughtful material selection ensures optimal functionality for Stella Terra’s components.
The tank holder is a new part in this year´s racing car. The part is printed on the FUNMAT PRO 610HT with the material choice of ABS. For the driverless disciplines, the team uses pressurized air to activate the brakes in an emergency. This year, they changed the concept of how pressurized air is stored, which required a new mounting solution. The tank holder is designed to solve this challenge.

Other 3D printed parts, using the FUNMAT PRO 610HT and PC material, are the flap ribs that play a crucial role in the construction of the car’s side wing. These ribs are glued into the carbon-fiber shells and incorporate threaded inserts for attaching the wing to the chassis.
While the team has used these ribs for years, they have redesigned for this season to accommodate changes in the aerodynamic shape of the wings. Using INTAMSUITE™ NEO and the 3D printing technology, they conducted topology optimization to achieve the lightest possible geometry, resulting in an organic shape that would not be possible to manufacture by milling.
