Direct metal laser sintering, also called DMLS, is a method of industrial 3D printing for metal that can produce completely functional metal prototypes and production parts in as little as seven days. Many metals are utilized in manufacturing finished products that can be put to various end-use applications.
The high-resolution DMLS 3D Printing and processing technologies have made the rapid prototyping of intricate metal parts possible. One of the first high-resolution fabrication methods to compete with traditional manufacturing processes involved the total melting of powdered materials. In sintering, the powder was sintered at high temperatures to produce metals with a good grain structure, allowing for great mechanical properties.
Direct metal laser sintering (DMLS) is a process that uses a high-energy additive manufacturing technology, also known as direct digital manufacturing technology, to build parts from the ground up. It is an advanced form of 3D printing. In DMLS, the part is fabricated layer by layer using a laser beam to melt successive layers of powdered material (in most cases, the powder is titanium).
Prototyping in production-grade materials
DMLS can be used to produce metal parts at a high volume, with techniques now available that allow the technique to be applied in production-grade metal alloys with the help of dmls printer service. To take its capabilities to the next level, DMLS 3d printing service must overcome a few key challenges. One of the most important is the ability of DMLS to produce small-scale features typically produced through traditional manufacturing techniques such as injection molding or foundry machining.
Complex geometries
Even with the development of high-speed additive manufacturing techniques such as DMLS, the complicated geometry often required for production applications in a wide range of metals requires even more specialized tools. It creates a challenge for DMLS 3D Printing since it must operate at speeds comparable to those required by typical injection molding. Injection molding can create complex geometries within the same tool through multiple stages of rapid move-making, while foundry machining adds another layer of complexity regarding creating tool paths.
Functional, end-use parts
When considering a high-volume manufacturing technique, it's important to consider the product's end-use. For example, a prototype part may be used in research and development (R&D) or to test new technologies. A production-grade part, however, needs to be reliable and robust enough to be used in an actual end-use environment.
