Protomold Canadian Laser Aggressive Eng. Exceptional accuracy allows use in the jewelry industry. Accuracy is partly enabled by a milling step after each layer deposition. Smooth cosmetic surface quality can be achieved by pre-tracing the perimeter of a layer prior to filling in the interior. The supporting wax material is deposited at the same time as the thermoplastic.
Models are primarily for appearance use.
The system is fast compared to most other RP techniques, and produces good appearance models with minimal operator effort. The main market that this system is targeted at is the engineering office where the system must be non-toxic, quiet, small, and with minimal odor. The ability to produce quick models means greater productivity for the lab and quick prototypes for customers. Since manufacturing parts is easy, almost anyone in the lab can produce a quality part without extensive Rapid Prototyping experience. Without milling step, work plane can become successively skewed.
