Robusta G

Applications

Functional prototypes that need to be tough
Snap-fit models
Jigs and fixtures


Material Overview

Robusta G has all the benefits and convenience associated with Formula L1 but is significantly stronger, which opens up an additional range of uses. It is best used for parts where toughness is a key requirement, or for master models for vacuum casting. Its texture and bright white color is very similar to that of ABS and other thermoplastics, making it ideal for prototyping and functional testing.

 

Advantages

Very strong and durable
Convenient to clean and finish
Highly detailed
Accurate
