Best where stiffness and a premium finish matter - gears, structural brackets, robotic end-effectors, drone parts and tooling. Note: not ideal for automotive (hydrocarbon exposure) or sustained high-temp use (73°C HDT); support bridges and overhangs well.

Key Benefits

Why print in Rizium CF

KB-01

Stable at negative temperatures

Holds its mechanical properties in sub-zero conditions, so parts stay reliable in cold environments.

KB-02

Lighter weight

Lighter than standard FDM materials - parts weigh less without giving up performance.

KB-03

Nylon-like, far easier to print

Similar properties to Nylon and comparable composites, but much easier to print - no warping and no need to dehydrate the material.
