Avoiding Design Pitfalls with 3D Printing

RedDOT designs and builds mobile heating, ventilation and air conditioning (HVAC) systems and components for on-and off- highway vehicles including commercial vehicles used in construction, agriculture, military and other demanding applications.

The company’s products typically include custom injection molded parts, which often cost hundreds of thousands of dollars apiece. Functional prototyping is critical to avoid design changes that might require expensive tooling modi cations or rebuilds.

“We can now make nylon prototypes with nearly the exact same properties as production parts.”
