3Dresyn VAM UHTD90 Bio, Biocompatible ultra hard & tough resin with Shore D90 printable by VAM 3D printers

Product description

3Dresyn VAM UHTD90 Bio is an ultra hard and tough photopolymer for VAM 3D printers.

This material is designed for durable high performance applications requiring high flexural strength, high tensile strength, high hardness, toughness and high resolution. It is also described as isotropic, clear and non yellowing for ophthalmic lenses.

Application framework

Designed for use in VAM 3D printers for fabrication of ultra hard and tough parts, including durable molds for injection temperatures up to 100ºC and isotropic clear non yellowing parts for ophthalmic lenses.
