3Dresyn SA2 LV Bio, Biocompatible Flexibility and Softness Adjuster with low viscosity for detailed flexibility adjustment

Product description

3Dresyn SA2 LV Bio is our low viscosity biocompatible flexibility adjuster for detailed flexibility refinement of any of our 3Dresyns.

It is normally used up to 5-15% dosage, or more depending on printer and rigidity specifications for certain thickness, and it is used for adjusting the rigidity and hardness of any 3Dresyn with Shore below or above D40 to your personal choice.

Application framework

Designed for use as a low viscosity flexibility adjuster in SLA, DLP and LCD vat photopolymerization workflows for detailed flexibility and rigidity refinement of compatible 3Dresyns.
