The size of the facets affects both the smoothness of the surface and the size of the STL file. Anything smaller will not improve the surface finish but will significantly increase the file size. Simply give us a call and provide the part's volume and maximum X, Y and Z dimensions. If you are considering ATI as your prototype supplier, submit a credit application with your request for quotation.
Nothing beats hands-on experience when selecting materials.
Digesting information from a material spec sheet can be tedious and often misleading. Let one of our Account Managers help you in selecting the right material. If you plan to use your rapid prototype as a pattern for any secondary tooling process, don't forget to notify your Account Manager of the appropriate shrinkage compensation. If Accelerated Technologies is doing the RTV molding or coordinating a secondary process, we will always include the appropriate shrink factor in the STL file. The physical model is much more clear in describing your design.
