Although 3D printing is commonly linked with producing plastic prototypes and finished parts, technological advancements have resulted in the development of a sophisticated metal sintering process. This method, known as DMLS 3D printing, enables the creation of precise and top-quality components made from materials such as stainless steel, titanium alloy, nickel base superalloy, and die steel. DMLS 3D printing offers the flexibility to manufacture functional metal prototypes and parts with intricate geometries and is ideal for low-volume production.
DMLS stands for direct metal laser sintering, an industrial 3D printing technology specifically for producing robust metal parts quickly and cost-effectively. It is like SLS additive manufacturing, as it builds parts from powdered metals one layer at a time. This way, the process can realize highly complex shapes without support structures.
Discerning product manufacturers, engineers, and designers consider DMLS 3D printing as one of the alternatives to CNC machining or die-casting, especially when building designs with complex geometries. They could cut costs and reduce turnaround times by choosing direct metal laser sintering over traditional manufacturing methods.
Build robust products with precision.
DMLS uses powdered metals with optimum dynamic and mechanical properties, making it ideal for creating end-use parts and production-grade prototypes. The 3D printing process deviates from the standard design-for-manufacturing guidelines, making it possible to create designs in a single piece instead of producing multiple assemblies.
DMLS 3D printing can generate accurate parts with complex lattice-infilled walls, internal channels, and shapes, which would have been impossible to produce with other manufacturing methods. As such, it can deliver more efficient, lightweight, and enhanced parts.
DMLS additive manufacturing is more sustainable than other manufacturing methods. It lets you maximize the use of high-cost materials, such as titanium, avoiding waste. Any residue or remaining powdered metals are reusable for other projects.
3D-printed metal parts do not need tooling, ensuring rapid turnaround. With DMLS 3D printing, the manufacturing lead time could be reduced to days instead of weeks, allowing for quicker time to market and faster innovation.
