A customer recently utilized our 3D printing services to manufacture a prototype of a shipping fixture. The design engineer chose a nylon filament alloy for the printing material because of its increased tensile strength, low shrinkage factor, durability and chemical resistance.
The design called for two components to be printed so the fixture could be snapped together and bolt holes kept in alignment. The use of 3D printing in this scenario reduced costs approximately 50% when compared to traditional machining.
Although just a prototype, the design engineer is considering 3D printing as the production method since these components will have a relatively low build volume. Depending on volume, a return to traditional methods may be required. For prototyping, 3D printing was an excellent choice.
