SCR@M focuses on competing with Plastic Ants (PLAnts), and so all structural materials used on the robot should be 3D printable. Below is the list of recommended filaments.
Materials that are not allowed for SCR@M (even if they are conventionally 3D printable)
SCR@M attempts to standardize the mounting hardware used on robots for logistical and purchasing simplicity. We acknowledge that bolt lengths are difficult to standardize, and so we focus on standardizing the class of hardware.
This is the hardware used to put pieces of the robot together. This could be attaching frame pieces to each other, attaching mounting pieces to the frame, etc. Aside from plastite screws, the standard fastener class for general mounting hardware is M3x0.5
This is hardware used to mount components to the motors. This could be attaching motors to the frame, or attaching components to the rotating section of the motor.
| M3 Bolts (structural mounting) | See Above |
|---|---|

These are components used in the transmission of power. For SCR@M we generally standardize power transmission to either direct-driven or belt-driven components.
