3Dresyn NMF Bio Scaffolds1 Biocompatible photopolymer for nano and micro fabrication

3Dresyn NMF Bio Scaffolds1 is a UV & EB curable organic biocompatible photopolymer for nano and micro fabrication, including printing of tough stamps for Nano Imprinting Lithography NIL, tough negative photoresists for standard UV lithography and PCB technology processing, and UV patterning of core and cladding.

This resin exhibits properties in between quartz glass and PDMS and provides a combination of rigidity, biocompatibility, high optical clarity and very high resolution for nano and micro fabrication workflows.

Designed for nano and micro fabrication, UV lithography, PCB technology processing, Nano Imprinting Lithography NIL, spin coating, Reactive Ion Etching, wet and dry etching, and optical microfabrication workflows.
