Fixturing for Assembly, Machining, etc. It may surprise some to learn that FDM parts are accurate and robust enough to be used as fixtures and jigs for assembly and machining. Also, FDM parts themselves can be machined to achieve a very nice result. Because of these things, more and more FDM parts are being used as fixtures and jigs. For machining fixtures, the FDM part is simply designed to conform to the CAD model of the desired finish part. This is especially nice for parts with complex surfaces that will be difficult or impossible to hold without a fixture. It can then be drilled, tapped, machined etc. in order to achieve a cost effective and quick fixturing method. And, you can use your machining center to work on your part, and not to make a fixture; let the FDM machine do that for you! The same holds true for assembly; the FDM part can be designed to hold two or more parts in position for assembly and fastener applications, or for gluing/bonding, etc. Also, with FDM, complex fixtures can be created with undercuts and cavities that may be extremely difficult or impossible to create with traditional methods of machining etc. If you can conceive it, FDM can do it!! And it’s done while you sleep or while you are working on something else. NOW THAT'S A BENEFIT!!!
