Hey all, This was a summer project to create a one piece 3D printed electric long board. I had previously printed long boards, but they were all made in multiple pieces. It is printed out of a material called Ultem 1010 which is an aerospace grade material. It has great properties when it comes to strength and thermal stability. I modeled it to withstand the fatigue of a 280 lb person.
Electronics: 120a Castle Talon ESC 2 x 4s 5000mah 20C Lipos Traxxas Transmitter/Receiver Hacker 12L-16 V2 Brushless Motor
The Lipos are wired in Parallel
The board took 6 days to print on an industrial 3D printer. The drive train was kind of an after thought. Since I couldn’t weld the cast aluminum trucks, I machined some parts to mount a 3D printed mount. The motor mount was printed out of Ultem 1010 as well after the original 3D Printed ABS mounts broke. In addition the wheel pulley is printed.
The electronics cover on the bottom is 1/8" aluminum plate water jet cut. M4 bolts screw into 4 melt in pem nuts in the board.
Let me know if you have any questions!
