Improved Injection Molding with Additive

3D printing is commonly used to build prototype parts for the detection of issues related to form, fit and function. However, 3D printed prototypes cannot provide a complete assessment of an injection molded part’s functional performance due to the fact that 3D material properties are different than those actually used in injection molding. Until recently, the only option for manufacturers to conduct design and functional testing of injection molded parts was to machine an aluminum (soft) tool. Today, PolyJet 3D printed injection molds are a better option for evaluating part design and performance. Using data from CAD files along with its inkjet-like process, PolyJet 3D printing can deliver high resolution and smooth surfaces that are ideal for building injection molds capable of producing prototype parts in end-use thermoplastic. Plus, they can be constructed in one or two days as opposed to days and weeks for metal tools.
