Full Spectrum Laser has released a new stereolithography resin that can be cleaned with just water and doesn’t need any expensive solvents or cleaners. The new 3D printing photopolymer has a highly attractive finish with excellent mechanical properties, and any excess resin material left on the print can easily be dissolved by rinsing with plain water. The Water Washable Resin is now available for sale online at $150 per 1 liter bottle, which is roughly the same price as standard resin materials.
