Process permissions allow you to specify which types of additional special manufacturing processes you will allow, or require, when making your part. Special processes you allow will be
used only when cost (or time) effective. For example, enabling Molding/Casting means your job will be molded or cast only if it saves you money or time. Processes you require will be used unconditionally. If you uncheck all special processes only conventional processes will be used.
Additive extrusion – Forms your part by CNC controlled extrusion of a .01" to .02" diameter plastic extrusion. This process builds up your part layer by layer. This results in a permeable material that is not recommended for holding liquids or gases. (Generally recommended only when very fast delivery is required.) Be sure to see the details of this process.
Molding/Casting – Forms your part by molding or casting. These processes create a slight line where mold sections meet and where ejection mechanisms push the workpiece from the mold.
Manual machining – Allows for non-CNC machines to be used. This may lower cost for very simple parts at very low quantity, at a slight sacrifice in surface uniformity.
Secondary processes for intricate thru cutouts – When you have cutouts that go fully thru your part and have sharp or small radius corners, the analyzer might advise you that some of the material might not be removed due to the limitations of conventional machining. With this option you can request that extra steps be taken to remove such material (at higher cost).
