Metal 3D Printing Material Options
Below is our available metal alloys for 3D printing. Various heat treatments are available depending on material.
Stainless Steel (17-4 PH)
Stainless Steel 17-4 PH is a precipitation hardened stainless steel that is known for its hardness and corrosion resistance. If needing a stainless steel option, select 17-4 PH for its significantly higher tensile strength and yield strength, but recognize that it has far less elongation at break than 316L. Final parts built 17-4 PH receive vacuum solution heat treatment as well as H900 aging.

Stainless Steel (316L)
Choose 316L when stainless steel flexibility is needed; 316L is a more malleable material compared to 17-4 PH. Final parts built in 316L receive stress relief application.

How Does Metal 3D Printing Work?
Direct Metal Laser Sintering (DMLS) is an advanced metal additive manufacturing process that builds fully dense metal components directly from a 3D CAD model. A high-powered fiber laser selectively melts and fuses thin layers of atomized metal powder inside an inert atmosphere, producing complex geometries with exceptional precision and material performance.
After each layer is fused, the build platform lowers, and a recoater applies a fresh layer of powder. This process repeats until the entire part is complete. Once printing is finished, excess powder is removed, followed by stress-relief heat treatment, build plate separation, support removal, and finishing operations such as bead blasting, deburring, precision CNC machining, and surface finishing.
The finished parts offer near-100% density, outstanding mechanical properties, tight dimensional tolerances, and excellent structural integrity, making DMLS ideal for functional prototypes and end-use production components across aerospace, medical, automotive, energy, and industrial applications.
