Spark has an in-house Stratasys 3D ABS printer. With this 3D technology called FDM [Fused Deposition Modeling] we can "print" real ABS plastic parts in hours. These plastic parts need little clean up, are very strong and are in a solid color. Spark prices these superior FDM parts at approximately 60% of an equivalent prototype part from a rapid prototype service.

With these plastic prototypes we can evaluate the design intent, ergonomics and aesthetics. The prototypes can be used to test assembly, fit, structural integrity and durability. Prior to production the prototypes can also be finished and used as casting, sales, and promotional models.
