Rapid prototyping systems classification

In the current market place there are three types of RP systems are manufactured:
LIQUID BASED SYSTEM:
-Uses the material in the liquid state like photo curable liquid resin etc.

1. 3d systems' Stereolithography  Apparatus(SLA).
2. Cubital's Solid ground Curing.(SGC)
3. Sony's Sollid Creation system.(SCS)
4. Mitsubishi's Solid object Ultraviolet-laser plotter(SOUP)
5. EOS's Stereos systems
6. Teijin Seiki's Solidform System
7. Meiko's Rapid Prototyping System for the Jewellery Industry.
8. Mitusui's COLAMM
9. Light Sculpting.

SOLID BASED SYSTEMS:
Expect for powder solid based systems are meant to use all forms of material in the solid state.

1. Helisys' laminated Object Manufacturing(LOM)
2. Stratasys' Fused Deposition modeling.(FDM)
3. KIRA's Selective Adhesive and Hot Press.(SAHP)
4. Kinergy's Rapid prototyping Inc.'s Model Maker MM-6B.
5. 3D systems' Multi Jet Modeling System(MJM)
6. IBM's Rapid prototyping system(RPS)\

POWDER BASED SYSTEMS:
