Errors must be fixed before the building stage occurs. After error checking, the RP computer slices the Model into cross-sections. Parameters are set related to the thickness of the sections. Items like cure depth, laser power etc. are also determined in the preparation stage as needed. Thus operators can leave and tend to other busisness while the part is being produced.
Build times vary depending on size and number required.
The number of that can be built at one time is limited only by the size of the RP system. Postprocessing - The final step in the process involves the removal of any unnecessary material from the prototype. This can be done in a variety of ways, depending on the RP process that was used. For example, SLA parts must have supports removed, and then are typically sanded to obtain a smooth outer surface finish. SLA parts also have an associated cure time.
