An additive manufacturing process using a CO2 laser to sinter (fuse) durable thermoplastic or metal powder into functional 3D objects. Some benefits of LS are:

• - Durable, functional parts
• - Low-volume, end-use production parts
• - Living hinge and snap capabilities
• - Variety of nylon, metal, and elastomeric materials
• - Fixtures, jigs, and assemblies
• - Rapid tooling

A layer-additive build process that uses a (UV) laser to solidify liquid, photo-sensitive resins. Some benefits of SL are:

• - Clear and opaque materials
• - Layers as small as .002 inch (two thousandths)
• - Fine feature detail
• - Light-duty, functional prototypes
• - Presentation models
• - Casting patterns

Similar to inkjet printers, most machines in this process deposit material or binder from print heads to create three dimensional (3D) objects. Options include:

• - Polyjet
• - Z-Corp
• - Projet
• - FDM (fused deposition modeling)

Cast reproductions of SL and LS patterns from temporary molds. Options include:

• - Urethane casting (RTV tooling)
• - Plaster casting
• - Investment casting
• - Sand casting
• - Spin casting
• - Rapid and traditional injection molding

A subtractive process by which a high-speed cutting machine removes unwanted material from a billet of raw material. Some benefits of CNC are:

• - Wide selection of plastics, metal, and alloys
• - Tight tolerances
• - Sharp feature detail
• - Functional prototypes
• - Excellent repeatability
