CNC machining allows customers to have a prototype produced out of the real material instead of a photopolymer or polyamide simulant. From nylon to aluminum, Star Prototype specializes in creating the highest quality CNC machined parts at low cost to the customer. CNC machining is typically used for projects with 50-100 sets of components, as a simulant material is not sufficient for those types of applications.
Plastics: Star Prototype can manufacture CNC machined prototypes out of the following high-quality materials, among others:
PMMA (Lucite Acrylic), PC, ABS, POM (Delrin), PTFE (Teflon), Ultem, Noryl, Nylon
Metals: We can also machine metals by using heat-shrink cutter holders for our high-speed spindles to ensure cutting accuracy. Common metals used for CNC prototypes include:
Aluminum, Copper-based materials, Tool steel
Quality & Inspection
Star Prototype is committed to producing the highest quality CNC machined prototypes. To meet this goal, we have invested in a portable FARO Laser Scanning Arm, which can be positioned next to the machine to inspect 3D parts before they are removed from the machine. Additionally, all of our CNC operators attended a technical polytechnic and have undergone further training in-house under US Master Craftsman Jay Hood.
Our general tolerances for CNC machining of metals is DIN-2768-1-fine and for plastics DIN-2768-1-medium. Tolerances are greatly affected by wall thicknesses, material choice, and geometry, so we will seek to advise as to achievable tolerances for each part. We pride ourselves on wishing to help our clients achieve their desired tolerances that are better than DIN-2768-1, but we work on a “best effort basis only” if the tolerances stated are tighter than our stated standards. The reason we refuse to be held accountable for very tighter tolerances is that we are a prototype factory and very tight tolerances present a huge risk due to the nature of our work.
