Digital Additive Manufacturing Material Blending to Achieve Impact Resistant Materials with Over-Molding for a Direct Use Hand-Held Instrument Housing

加拿大环境仪器公司为铀矿开采业、住宅辐射控制和公共辐射安全提供辐射安全解决方案。加拿大环境仪器公司已经完成了使用增材制造/ 3D打印技术直接制造手持式仪器外壳的初步工作。最初的结果非常令人鼓舞，因为能够在一次打印中打印基础部件和包覆成型，而且还因为增材制造实现了完全的设计自由度。虽然它们在功能上非常有前途，但从制造组装韧性以及跌落测试的角度来看，初始原型并不像期望的那样耐用。该项目与萨斯喀彻温省理工学院的增材制造和原型研究（RAMP）设施将研究增材制造材料的数字混合，以生产更坚固耐用的基础材料，该材料仍然可以与橡胶类材料一起包覆成型，所有这些都在一个3D打印中。

Environmental Instruments Canada Inc. provides radiation safety solutions for the uranium mining industry, residential radiation control, and public radiation safety. Environmental Instruments Canada Inc. has done preliminary work on direct manufacturing of housings for hand held instruments using Additive Manufacturing / 3D printing technology. Initial results are very encouraging because of the ability to print the base part and the over-mold in a single print, and also because of the total design freedom enabled by Additive Manufacturing. Although they are functionally very promising, initial prototypes are not as durable as desired, both from manufacturing assembly toughness as well as from a drop test point of view. The project with Saskatchewan Polytechnic's Research in Additive Manufacturing and Prototyping (RAMP) facility will examine digital blending of Additive Manufacturing materials to produce a tougher and durable base material that can still be over-molded with a rubber-like material, all in a single 3D print.
