Direct Metal Laser Sintering (DMLS) 3D Printing Service
DMLS parts are stronger and denser than investment casted metal parts, and they can help you get to market first with faster turnaround times.Since components require no tooling, design changes can be implemented rapidly. This allows parts to be manufactured overnight and put into use within days.

What Is DMLS?
DMLS (Direct Metal Laser Sintering) is an additive manufacturing method. It additively manufactures parts by sintering fine metal powder particles, locally fusing them together. Like the SLS process, your metal part will be created layer by layer according to your 3D model. The main difference is the sintering temperature. Polyamide needs to be sintered at a temperature of 160°C to 200°C, while the melting temperature of metal is about 1510°C to 1600°C, which means that a higher wattage laser is needed to reach this temperature.
First, the roller is coated with a layer of metal powder, then the laser sinters the powder according to the 3D file, then the build platform is lowered and a new layer of powder is applied… This process is repeated until the desired part is created. Once completed, the metal part needs to cool before it can be removed. If the metal part requires supports, these will be removed manually.
Advantages
Printed parts with DMLS technology are durable, lightweight and precisely detailed.
- Print complex geometries with strong and durable components
- Rapid prototyping with high quality and high accuracy- ideal for functional testing
- Create complex shapes, intricate details and delicate features
- Reduce cost & development time by consolidating parts, no tooling required
- Build parts in a matter of hours
When to use DMLS
For high volume production of highly complex geometry (not possible by MIM or die casting), investment casting with 3D printed pattern will be more economical.
- Functional, end-use parts
- Prototyping in production grade materials
- Low volume production (Qty < 250)
- Highly complex geometry which is impossible to generate through CNC machining
- Lattice structure metal part for weight reduction
- Specific requirement such as high temperature performance, corrosion resistant, etc.
What processes can DMLS be used with?
DMLS parts are dense and have similar mechanical properties to cast parts. Where tight tolerances are required, DMLS parts can be 3D printed at a near-net shape and then machined to meet them.
Once a part has been produced using direct metal printing, it can be improved using processes that are common to finishing metal parts, including media blasting, metal plating, micromachining and polishing. Holes or threads may be added to parts using CNC machining.
Titanium is notoriously hard to machine. For aerospace applications, where light weight and strength are a must, DMLS can be used to produce strong, lightweight parts using this exotic material.
