Technical specifications

Direct Metal Laser Sintering or DMLS is an industrial metal 3D printing technology. It is a powder bed fusion process similar to SLS, which builds parts from a range of metal materials one layer at a time by sintering metal powders together.

DMLS 3D printing is a process capable of building highly complex shapes which would be near impossible to make via other methods. This technology promises to have a massive range of applications as it improves and becomes better understood.

DMLS (Direct Metal Laser Sintering)

Direct Metal Laser Sintering (DMLS) – also known as DMP (Direct Metal Printing) – uses a precise, high-wattage laser to micro-weld powdered metals and alloys to form fully functional metal components direct from CAD data. In many cases, DMLS eliminates time-consuming tooling and can create complex geometries impossible with other metal manufacturing processes. While Stainless Steel is the most commonly utilized material, other options include Inconel, Aluminum, and Titanium. DMLS parts are strong, durable, and heat-resistant. DMLS parts are also denser than investment cast metal parts. This exact metal 3D printing process provides fine feature detail, making it ideal for complex oil and gas components, intricately detailed small components, custom medical guides, consolidated aerospace parts, and tough, functional prototypes.


Features of DMLS

Strength & Durability

Fully densed metal material with strong mechanical and dynamic properties, perfect for end-use parts.


DMLS allows to integrate multiple components as well as thin-walled objects and intricate geometries that traditional method won’t be capable of.

Scalable Volume

Multiple, identical parts can be built on a single platform at one time, greatly increasing production efficiency.


Metal 3D printed parts do not require tooling which reduces the manufacturing lead time from weeks to days, allowing for faster innovation and speed to market.


Designs can be made quickly with a minimum of material waste while maximizing strength.

Material Selection

A variety of metal alloys are available for special requests like Inconel, brass and even tooling steel.

We provide designers and manufacturers with a variety of 3D printing services, to create custom high-performance prototypes, tooling, manufacturing aids, end-use parts, and low-volume production.
By applying DMLS Technology, our staff of highly-experienced specialists are capable of meeting the most stringent demands in terms of time, cost and precision in the creation of your part.

DMLS Technology Advantages

How does it work?

DMLS micro-welds powdered metals and alloys using a precise, high-power laser to form fully functional metal parts from your CAD models.

DMLS parts are made from powdered materials such as aluminum, stainless steel, and titanium, as well as other niche alloys.

Finished parts

Raw DMLS parts have a surface finish comparable to fine investment cast parts, sometimes requiring professional finishing services.

elimold offers a full range of specialist finishing operations, including precision machining, media blasting, surface grinding, and milling.

Create metal parts faster

Metal 3D printing is ideal for complex oil and gas components, custom medical guides, part-consolidated aerospace parts, and tough, functional prototypes.

Utilize the design freedom of DMLS and produce accurate metal components in less time than other manufacturing methods.
