SRP® (Subtractive Rapid Prototyping) - starting with a solid object and removing unwanted material - has several advantages over traditional additive rapid prototyping. SRP devices cost significantly less while producing prototypes out of a wider variety of non-proprietary materials with greater precision and better surface finish.
Todd Grimm, the man who wrote the book on rapid prototyping for the Society of Manufacturing Engineers, found that Roland SRP devices produce prototypes faster, better and cheaper than most additive RP systems. Download the Choosing the Right RP System Brochure PDF Format (1.9 MB)
