DMLM – Direct Metal Laser Melting

Fathom is a service provider of Direct Metal Laser Melting (DMLM), the latest technology for 3D printing and additive manufacturing of 3D printed metal parts. Fathom produces 3D metal parts for applications ranging from prototypes to production. DMLM technology is ideal for a variety of applications including the creation of conformal cooling channels for injection molding tooling. DMLM is commonly known by the acronym DMLS for Direct Metal Laser Sintering.

Utilizing the DMLM process, metal parts of the most complex geometries are built layer-by-layer (down to 20 microns) directly from 3D CAD data. Parts built using DMLM have excellent mechanical properties equivalent to wrought materials, high detail resolution, and exceptional surface quality. The metal powder is melted entirely to create a fully dense, fine, homogenous structure. Unique geometric freedom of design enables DMLM to form cavities and undercuts, which with conventional machining methods, can only be produced with great difficulty—if at all.

When a part needs to be tested and re-designed over and over, the lead time for receiving a traditionally tooled part can create a large bottleneck in the final production process. DMLM produces parts that are extremely high quality and can be built in a matter of hours or days rather than weeks. The ability to generate functional metal prototypes in short order radically impacts design processes, accelerating design cycles and time to market.

Depending on size and geometries, the turnaround time for a part can be as little as a few hours. These parts are highly functional and can undergo real-world testing in the environment for which they were designed. This technology delivers unlimited potential for engineers to create previously impossible solutions, embracing a new era of design-driven manufacturing.

Fathom utilizes both EOS and SLM DMLS machines.
