Introduction
Robusta LR is a high tough, white photocurable resin for challenging model processing. Robusta LR is not as strong as Robust G in terms of impact strength and elongation at break, but tensile strength and flexural modulus Robusta LR are higher, thermal performance is superior to Robusta G, and printing accuracy is higher.
Details
As a high-tough material series, Robusta LR offers better elongation at break and impact strength, and higher thermal performance and precision. It is best suited for models and parts that require high toughness, or prototypes used to make vacuum complexes. Its texture and color are very similar to ABS and other thermoplastics, making it ideal for prototyping and functional testing.
Advantages
Very tough and very durable
Easy to clean
Fine surface texture
High precision
Applications
Functional hand model with high toughness requirements
Snap-on model
