Pleiger Plastics offers prototyping services that are available for most custom molded products. Our polyurethane prototyping utilizes machined metals, FDM, SLA and SLS in conjunction with the cast urethane process to provide rapid prototypes. The customer is able to further refine their product and perform tests without significant tooling investments, and a full production run.



FDM is short for Fused Deposition Molding and is essentially a filament of .01” diameter plastic that is extruded through a printing head in a very specific pattern. The final part has a distinct line pattern on the outside surfaces which will translate into the molded part. FDM parts normally require more time than SLS; however, they are more durable and lower cost.



SLA is short for Stereolithography, where layers of material are built up by exposing special reactive liquid polymers to UV light.  Layer thicknesses can vary between .004″ and .001″.  The final part has detail approaching machined metal and can be made flexible or rigid.  The primary disadvantage with SLA is print time and required support structure.  Click here to see the support structure.



SLS is short for Selective Laser Sintering and is essentially small spheres (.004”) of plastics that are fused together by a laser. The final part has much better detail than FDM parts.



Machined Metal is simply a metal blank CNC machined to the part’s dimensions. These prototypes are the most durable and most expensive, however, they have excellent detail. The primary disadvantage is when making a part with lettering, the letters will be recessed.
