New erase-and-reprint resin survives 10 cycles of high-precision 3D printing

Yokohama National University researchers developed an anthracene-based resin for high-precision 3D printing that cures without photoinitiators.

The resin can be heated back into a liquid and reused, and it held up through 10 recycling cycles in tests.

It was demonstrated in detailed stereolithography and two-photon lithography printing, with limited loss of print quality.

The work, published in ACS Omega, points to a more sustainable way to reduce waste from photopolymer 3D printing.
