The company Full Spectrum Laser, the manufacturer of 3D printers Pegasus and Pheonix recently announced the release of a new material for 3D printing - water-washable photosensitive photopolymer, the remains of which after printing the main part are removed with plain water, without the use of chemicals. At the same time, the part itself can be safely thrown into the water - it will not dissolve.
Photopolymer resin is absolutely safe for use in training sessions in educational institutions, and at the same time provides very good print quality, high enough even for prototyping a professional class. This water-washable material is easy to use and compatible with almost any 3D printer using stereolithography technology (SLA) or digital LED projection (DLP).
As you know, the technology of stereolithography allows you to get high-quality prints, which in most cases do not even require finishing processing of the coating. However, after the 3D printing process is completed, excess photopolymer resin must be removed - for this, the finished print is immersed for several minutes in a solvent based on acetone or isopropyl alcohol. These chemicals, in addition to a rather unpleasant odor, can cause poisoning or allergies (which is not a buzz for schools), and also pose a danger to the environment.
The new material provides not only safety, but also ease of use - the finished 3D-printed part is washed under running water or lowered into the water bath for some time. Excess material dissolves without a trace. Unfortunately, the company does not provide information on what the new material is made of, it remains only to rely on its statements on full compliance with WHO standards on safety for human health.
However, as the developers believe, water-washable photopolymer can be used in production - for the development and rapid prototyping of prints with high resolution and decent quality.
