Stereolithography (called SLA)
Developed by 3D Systems of Valencia, CA, and most widely used method, this technology imports 3D CAD data and converts it into a precise 3D physical model. It utilizes a laser to scan and solidify very thin layers of a photo sensitive liquid polymer, typically polyurethane. SLAs can be finished, painted, or textured to resemble production like parts. SLA’s, in some cases, can even be functionally tested for product performance. Parts are typically completed in less than a week!

Selective Laser Sintering (SLS)
This process uses a high power laser which selectively fuses powdered material by scanning cross sections generated and imported from a 3D CAD file on the surface of a powder bed. After each cross-section is scanned, the powder bed is lowered by one layer thickness, a new layer of material is applied on top, and the process is repeated until the 3D part is completed.

Fused Deposition Modeling (FDM)
An extrusion nozzle is heated to melt material and can be moved in both horizontal and vertical directions. In a similar manner to stereolithography, the model is built up from layers as the plastic hardens immediately after extrusion from the nozzle. Typical materials used are ABS, and Polycarbonate.

CNC (Computer Numerical Controlled) Machining
Use of a CNC milling machine or lathe to quickly produce precision components from various materials including steel, aluminum, and plastics.

RTV Tooling
Using an SLA master pattern, RTV (Room Temperature Vulcanized) rubber tools are created and used to cast polyurethane duplicates. RTV tooling is inexpensive, offers good accuracy and finish, and the parts produced are adequate for prototypes or small production runs. Painting and other secondary decorations can result in parts that are suitable for marketing decorations and trade show samples.

Rapid Injection Molding
Extremely fast and inexpensive method of designing and building injection mold tooling and delivering production quality plastic parts. Some limitations apply (cannot do unscrewing type cores or complex cavities or undercuts). Typical turnaround time is 3 to 4 weeks.
