HLH Proto’s DMLS 3D Printing: Create Metal Prototypes with Precision

Are you developing a new metal part? Conventional manufacturing methods can be time-consuming and costly. Fortunately, HLH Proto provides Direct Metal Laser Sintering or DMLS 3D printing, an additive manufacturing technology that enables the precise production of metal parts.

In addition to DMLS, HLH Proto specializes in other cutting-edge solutions that can expedite the prototyping process and reduce costs. These advanced technologies, coupled with their expertise in material selection and post-processing techniques, make HLH Proto an ideal partner for fast and efficient metal part prototyping.

Like SLS, DMLS crafts parts by sintering powdered material together. But instead of sintering plastic, it sinters metal powders to fuse them and build your part one layer at a time, making it capable of building complex details.

Why choose DMLS?

Direct metal laser sintering is a proven industrial 3D printing technology with plenty of potential for various applications. As technology evolves, its applications continue to expand as it improves and becomes more understood. DMLS is proven for its ability to produce complex parts that are more difficult or costlier to make with other methods and traditional manufacturing processes. That makes it much sought-after by aerospace and automotive industries that require high-performance parts.

Achieve more design freedom.

DMLS 3D printing is also versatile. You can use it to build functional metal prototypes, tooling, and medical prosthetics. Unlike traditional manufacturing methods, DMLS does not follow conventional design-for-manufacturing guidelines. So, even if you’re building a design that typically requires assemblies, DMLS can accomplish it in one go, saving you time and money. Plus, it ensures results with dynamic and strong mechanical properties, making your parts as good as end-use ones.

Quick and efficient

DMLS 3D printing delivers accurate and high-quality metal prototypes that are ready for display or testing. They don’t require tooling, so you can minimize manufacturing lead times from weeks to only a matter of days. So, it supports your efforts to innovate faster and bring your product to the market earlier.
