DMLS Additive Technology

< Back to On-Demand 3D Printing

How does it work?

Direct Metal Laser Sintering (DMLS) forms fully functional metal components from CAD models by using a precise, high-wattage laser to micro-weld powdered metals and alloys.

Benefits

Complex geometries with lattice structures and internal passages

High resolution and fine feature details

Fully dense metal parts

Wide range of materials

Good mechanical properties

Applications

Production Parts

Manufacture custom or one-off parts with LMPBF or replace low-volume castings with a 3D metal part.

Functional Prototypes

Parts are fit for full-usage scenarios due to the process characteristic hardness and durability.

Thermal Control Systems

Produce previously unmanufacturable designs, such as heat exchangers and thermal control systems.

Technical Data

Layer Thickness 20µm-25µm

Accuracy/Tolerance ±0.005 in

Max Single Size Part 9.85 x 9.85 x 12.8”

*Accuracy/tolerance may vary with part geometry, dimensions, and build orientation

*Numbers are based on published Stratasys data
