3D printing - DMLS

DMLS Produces High-Quality Metal Parts Without Tooling

Direct metal laser sintering (DMLS) is a metal 3D printing technology used to build metal parts with exceptional mechanical properties and precision. Our factory gives you massive on-demand production capacity with a wide range of DMLS machines and high-performance materials. CNC Machining Service.

Designers often chose DMLS for its ability to produce all-in-one metal assemblies and highly precise metal parts with complex features like internal supports and lattices. DMLS does not have upfront setup or tooling costs, making it an affordable option for fully dense metal parts. With DMLS’s affordability, speed, and superior design freedoms, companies and creators can build metal designs they never thought possible. 3D Printing service design

How Direct Metal Laser Sintering Works

Direct metal laser sintering (DMLS) is an additive metal printing technology that builds metal parts from a CAD file by selectively fusing stainless steel or aluminum powder into thin layers. Direct metal laser sintering’s layer-by-layer printing allows multiple parts to be combined during the printing process. With traditional manufacturing processes, metal parts are machined or metal casted into several parts and assembled. Printing an all-in-one assembly strengthens the finished part while reducing the weight and cost of production significantly. DMLS techniques can also create parts at a high density. This is ideal for parts under high pressure such as in oil and gas industries.

Direct Metal 3D Printing Materials

Material Name	Description
3D Printed Aluminum AlSi10Mg	Lightweight aluminum alloy. A great alternative to machining complex geometries.
3D Printed Stainless Steel 17-4	Fully-Dense 17-4 PH stainless steel metal, hardness 40 HRC, heat treatable.
3D Printed Stainless Steel 316/L	Fully-dense 316L stainless steel metal, superb corrosion resistance, meets requirements of ASTM F138.
3D Printed Maraging Steel MS1	A heat-treatable tool steel that can be post-hardened to more than 50 HRC to achieve excellent hardness and strength.
3D Printed Inconel 625	A heat and corrosion-resistant nickel alloy offering high oxidation resistance.
3D Printed Inconel 718	A heat and corrosion-resistant nickel alloy ideal for high-temperature applications. It offers good tensile, fatigue, creep, and rupture strength at temperatures up to 700 °C (1290 °F).
3D Printed Titanium Ti64	A lightweight alloy with excellent mechanical properties and corrosion resistance used in high performing engineering applications as well as biomedical devices.

Available Finishe

Standard

In addition to the removal of support structures, the part surface is media blasted to provide a uniform finish.

Custom

Additional DMLS post-processing, such as CNC Machining of features and polishing, are evaluated on a case-by-case basis and can be requested in the quoting tool.

Best Applications for DMLS

Rapid Tooling

Because DMLS metal parts are strong yet lightweight, they are widely used for rapid tooling, fixtures, and jigs.
Rapid Prototyping

DMLS metal 3D printing is typically affordable and fast, and therefore is often used to make proof-of-concept models and fully functional late-stage prototypes.
Production

Cast-quality finish (fully dense) and durable materials make DMLS printing a favorite technology for end-use products.
