SWOMP: Selective dual-wavelength olefin metathesis 3D-printing produces stronger nonmetallic output 5X faster

"printing layer by layer using a 2nd light wavelength preventing polymerization at vat's bottom so doesn't adhere to bottom when lifting cured polymer part more quickly, speeding printing process... changing building block materials from acrylic-based to olefin-based (dicyclopentadiene polymerized rapidly with UV and blue light) enables printing much tougher output... improves 3D printing accessibility in remote areas... extends 3D-printing to high-quality plastics, engines, batteries, monomers), fusion applications"
