Design Guidelines: Direct Metal Laser Sintering
Our basic guidelines for direct metal laser sintering include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.
|Normal Resolution||9.6 in. x 9.6 in. x 10.6 in.|
|High Resolution||3.5 in. x 3.5 in. 2.7 in.|
|Normal Resolution||245mm x 245mm x 270mm|
|High Resolution||88mm x 88mm x 70mm|
|Normal Resolution||0.00118 in.|
|High Resolution||0.00079 in.|
|Normal Resolution||30 microns|
|High Resolution||20 microns|
Minimum Feature Size
|Normal Resolution||0.015 in.|
|High Resolution||0.006 in.|
For well-designed parts, tolerances of ±0.003 in. (0.076mm) plus ±0.001 in./in. (0.001mm/mm) for each additional inch can typically be achieved. Note that tolerances may change depending on part geometry.
|STANDARD||Expect roughness values of 200 to 400 µin Ra (0.005 to 0.010mm Ra), depending on material and resolution.|
||Secondary options include hand-polished or machined surfaces upon request. When tighter tolerances are required, we can provide secondary machining operations such as drilling, slotting, milling, and reaming.|
We use multiple Concept Laser Mlab and M2 machines for DMLS production that offer large build sizes, produce accurate parts, and provide quick turnaround times. The Mlab is ideal for manufacturing metal components with elaborate structures, and is ideal when high surface quality and fine component structures are needed on parts. The Concept Laser M2 is a large platform machine that is able to produce larger metal parts than the Mlab. All of our 3D printing equipment can handle both reactive and non-reactive metal powder.
