CNC Machiningis a subtractive manufacturing method which cuts away unwanted material from primary stock to form the shape of the needed part. CNC Machining is a great process for manufacturing low and high quantities of quality metal and plastic parts.

Stereolithography (SLA)is a rapid prototyping process that uses a vat of liquid UV-curable photopolymer resin and a UV laser to build parts one layer at a time. SLA rapid prototyping is a great process for concept models, master patterns and tradeshow models.

Fused Deposition Modeling (FDM)is a rapid prototyping process that uses a plastic filament of material supplied to an extrusion nozzle. The nozzle is heated to melt the material and can be moved in both horizontal and vertical directions. FDM rapid prototyping is a great process for functional testing and for low volume manufacturing. It is especially helpful since the materials used are actual ABS and Polycarbonate. Ultem is also a material option.

Selective Laser Sintering (SLS)is a rapid prototyping process that uses a high power laser to fuse small particles of powder to build parts one layer at a time. SLS rapid prototyping is a great process for functional testing and for low volume manufacturing.

Cast Urethane Moldingis the process of using silicone molds to create urethane molded parts. Silicone is cast around a master pattern (typically made from stereolithography rapid prototyping). After curing, the mold is then used to form a two-part polyurethane material in the shape of the master. Cast Urethane Molding is a great process for pre-production runs andlowvolumemanufacturing.

PolyJetis a rapid prototyping process that jets photopolymer materials in ultra-thin layers (16µ) onto a build tray layer by layer until the part is completed. Each photopolymer layer is cured by UV light immediately after it is jetted. PolyJet rapid prototyping is a great process for concept models, master patterns and tradeshow models.
