Example Parts


Bike Handle

This bicycle grip was printed to functionally evaluate various textures in a looks-like, feels-like material before investing in a mold for high volume production.


Popless Tire

This tire is for a remote-controlled inspection vehicle. Since the vehicle is controlled remotely there is no way to repair it if something breaks. To ensure the tire never goes flat, a popless tire was used that features no air.



This pulley is pressed into an outer casing to provide stiffness and vibration dampening on the rotating components.
