3Dresyn NMF HAR1 Bio, Biocompatible High Aspect Ratio ultra rigid photopolymer for nano and micro fabrication

Product description

3Dresyn NMF HAR1 Bio is a UV & EB curable organic high aspect ratio and ultra rigid photopolymer for nano and micro fabrication, including printing of ultra rigid stamps for Nano Imprinting lithography NIL, negative photoresists for standard UV lithography and PCB technology processing, and UV patterning of core and cladding.

This resin exhibits properties similar to quartz glass and is designed for ultra rigid, high aspect ratio nano and micro fabrication workflows.
