Dual-Wavelength 3D Printing Could Lead to Wider SLA Adoption

April 24, 2024

Stereolithography (SLA) has long been a cornerstone technology in 3D printing, but its limitations have hindered its potential for mass adoption. Traditionally, SLA printers have relied on a single UV light source and free-radical polymerization (FRP) resins, resulting in a layer-by-layer printing process fraught with challenges. One significant issue was the peeling of each layer from the transparent film at the bottom of the resin vat, necessitating pauses in printing and subjecting printed parts to undue stress.

However, recent advancements, particularly from Sandia National Laboratories, could offer a solution for these issues. Their pioneering SWOMP (Selective Dual-Wavelength Olefin Metathesis 3D-Printing) technology introduces a novel approach using ring-opening metathesis polymerization (ROMP) and DCPD monomer with HM catalyst. Unlike conventional FRP resins, DCPD-based materials offer exceptional robustness and can undergo thermal post-curing for enhanced mechanical properties.

The key breakthrough of SWOMP lies in its dual-wavelength setup, which enables continuous SLA printing without the drawbacks of layer peeling. By selectively inhibiting polymerization at specific depths, SWOMP achieves unprecedented printing efficiency, surpassing traditional SLA methods.

Sandia National Laboratories is actively seeking partners to further develop and commercialize this technology, offering hope for widespread adoption in the 3D printing industry. With its potential to eliminate layer peeling and significantly increase printing speeds, dual-wavelength SLA printers could soon become a staple in manufacturing facilities worldwide, unlocking new possibilities for design and production.
