Direct Metal Laser Sintering (DMLS) is perfectly suited for Aerospace and UAV thermal, weight reduction and complex part requirements. Generally, 3D metal printing holds tolerances off the printer as tight as +/- .002 and prints densities above 99%, making tighter tolerance and post process requirement easily achievable. Our most popular metals in Aerospace and UAV are Inconel (thermal properties), Aluminum (thermal & weight advantages), and Titanium (Weight & Strength).
Aircraft Rapid Prototyping
The aerospace industry has used 3D printing for rapid prototyping for years. Direct Metal Laser Sintering (DMLS) uses 400 watt lasers to melt micron layers of metal powder together, eliminating binding agents, and producing production parts. Lattice and honeycomb designs for existing and new parts may reduce weights by over 70%. These designs cannot be traditionally machined nor cast but are now possible to prototype and then actually manufacture using 3D print technology.
