Metal Additive Manufacturing Built for Real Engineering
IA3D’s Direct Metal Laser Sintering capabilities produce dense, high strength metal parts directly from CAD data using laser powder bed fusion technology. Our systems support complex geometries, internal channels, lightweight structures, and consolidated assemblies that are difficult or impossible to machine traditionally.
DMLS enables engineers to reduce weight, eliminate assembly steps, accelerate iteration cycles, and manufacture highly optimized components without tooling constraints.

How Direct Metal Laser Sintering Works
DMLS builds metal components layer by layer using a high powered fiber laser to selectively fuse fine metal powder. Each layer is spread across the build platform, fused according to the CAD geometry, and repeated until the part is complete.
The surrounding unfused powder supports complex geometry during printing, allowing internal passages, lattice structures, and highly optimized part designs without traditional tooling limitations.
