the different is that the washable has is metal backed and can be used several times compared to the one is not. the best fotoplymer plates or solarplates are the one is metal back in washable. they sell at amazon very cheap

Advantages of flexography * Prints on wide variety of absorbent and nonabsorbent substrates. * Prints using resilient rubber or photopolymer image carrier,so that millions of impressions can be made. * can print more than 10 colors if multiple print station are used. * It uses fast drying inks which might be solvent based, water based or UV curable. * Cost effectivenukghj

The first 3D printer was created by Charles W. (Chuck) Hull in the mid-1980s. It used a technique called stereolithography, in which a UV laser is shined into a vat of ultraviolet-sensitive photopolymer, tracing the object to be created on its surface. The polymer solidifies wherever the beam touches it, and the beam "prints" the object layer by layer per the instructions in the CAD/CAM (computer-aided design/computer-aided manufacturing) file it's working from. Hull founded a company called 3D Systems, which made stereolithography machines. Stereolithography is an expensive commercial technique, with machines usually. Today 3D Systems sells 3D printers that use a variety of technologies and range from entry-level kits to advanced commercial systems, as well as providing on-demand parts services, mostly to business users.

For different filaments i can refer 3dpartistry. They provide all types of filaments.
