Rigid Materials

BenchRebel currently offers two rigid materials. The properties of a given raw material vary greatly in their strengths, and no single property trumps all others. For example, Rigid 4000 finishes smooth, stiff, and is ideal for think-walled parts; Rigid 10K is the stiffest material offered, finishes matte, and highly resistant to both heat and chemicals.

The examples highlighted above, and many more variables, will impact how a product is designed and manufactured. To help with that decision, design guidelines are provided below.

Design Guidelines

Rigid 4000	Rigid 10K

Rigid 4000 is a glass-filled resin that prints with a smooth, polished finish. Ideal for stiff, strong parts that can withstand minimal deflection. This material is a good choice for general load bearing, printing thin walls and features.	Rigid 4K is a highly glass-filled resin and the stiffest material offered. Best used for precise industrial parts that must withstand significant load without bending. This resin finishes smooth with a matte finish and is highliy resistant to heat and chemicals.
Mounts and brackets Jigs and fixtures Thin-walled parts Simulates the stiffness of PEEK Note: more brittle than the Tough series of materials	Prototypes requiring the toughness, compliance and resilience of polypropylene Tough and rugged enclosures with functional elements like self-tapping screw bosses and snap fits Impact resistant jigs and fixtures that survive long term use Parts that need a combination of stiffness and ductility to create compliant mechanisms like latches, flexures, and dampers Safe for skin (wearables)
