Design Guide for Reducing Supports in Metal Additive Manufacturing

This document is a design guide focused on strategies for reducing supports in metal additive manufacturing. It outlines the importance of support structures in the printing process, particularly for heat transfer and to prevent warping. The guide details various types of support structures and discusses what can be built without support, specifying conditions based on the geometry and material of the parts. It emphasizes the need to avoid downfacing surfaces and suggests creating self-supporting geometries. Additionally, it presents advanced strategies such as the use of NoSupports™ technology with 3DXpert software, which allows for metal 3D printing without traditional supports. The guide also covers the capabilities of different DMP printers and the materials suitable for additive manufacturing, including titanium, stainless steel, and aluminum alloys. Overall, the document serves as a comprehensive resource for optimizing designs and processes in metal additive manufacturing.
