Plastic And Rapid Prototype Options

For both low and high volume parts machined from solid stock, this method is recommended for tight tolerance projects. Part size can vary. Lead time: 1-2 weeks.

This is the most widely used RP technology. SLA enables the creation of complex, 3D models by successively “laser-curing” cross-sections of a liquid resin. A UV laser contacts the resin, which is a photopolymer, causing the material to solidify. It is widely used for conceptual visualization, form and fit analysis, pattern creation and light functional testing in an ABS-like material. Part size can vary. Lead time: 3-5 days depending on geometry.

This process is widely used for functional applications. The SLS process creates 3D objects, layer by layer, from powdered materials. Heat from a CO2 laser fuses (sinters) the powder within a precisely controlled process chamber. A major distinction between SLS and other RP technologies are the material selections, which include fine nylon and glass-filled nylon. Many of these materials prove suitable for function analysis. Part size can vary. Lead time: 3-5 days depending on geometry.

A plastic filament is unwound from a coil and supplies material to an extrusion nozzle. The nozzle is heated to melt the plastic and has a mechanism which allows the flow of the melted plastic to be turned on and off. The nozzle is mounted to a mechanical stage which can be moved in both horizontal and vertical directions. Part size can vary. Lead time: 3-5 days depending on geometry.

Using a technology based upon inkjet printers, this method is now available for cost-effective 3D design verification. Lead time: 3-5 days depending on geometry.

In this method, liquid silicone rubber is poured around a master. The resulting mold is withdrawn from the master and hardened, and then may be used to produce parts in cast urethane. This technique is used to produce a large quantity of prototypes at a relatively low cost. Urethanes are a good representation of an injection molded part. This is a price-effective option for low-volume runs, with a variety of colors, rigidity and materials. Lead time: 1-3 weeks depending on geometry.

SLA, SLS, FDM, CNC and Urethanes - all are good and each has its own place when considering rapid prototypes. We can help you select the method best suited for your needs based on your project parameters.
