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.

We offer a range of secondary CNC machining services to further enhance your DMLS project finish.

Typically, for well-designed parts, with a designated build direction, tolerances of +/- 0.1 mm to +/- 0.2 mm + 0.005 mm/mm are expected and achieved

Certain geometries may cause distortions due to internal stress, which may lead to higher deviations.

Surface Finishes


STANDARD Expect roughness values of 0.004 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 3D printing equipment for the production of metal components, which offer large build sizes, produce accurate parts, and provide quick turnaround times. Our EOS and Concept Laser 3D printing equipment can handle both reactive and non-reactive metal powder.
