3D Printing Metal Services via DMLS
Axis Prototypes employs state-of-the-art 3D printers to deliver rapid DMLS prototyping services.
We output 3D printed sintered metal prototypes to support a wide range finished and semi-finished applications in the aerospace, automotive, military, medical, and consumer markets, among others. Be it to print prototypes for design validation purposes, to manufacture the part, mold inserts, or assembly jigs and fixtures, DMLS printing opens up a whole new approach to manufacturing 3D printed metals.

Benefits of 3d Printing with DMLS Technology
•Your custom metal part can be built in hours, with no tooling required
•Ideal for functional prototypes, high-temperature applications, and end parts
•Cost-effective compared to traditional manufacturing methods for intricate parts
•Can reproduce complex geometries with high dimensional accuracy
•Parts with machined components that need to be assembled can be manufactured as a single component
•Inner channels and passages that are curved, such as conformal cooling channels in a tool and die, can be achieved with 3-d metal printing.
What is DMLS or Direct Metal Laser Sintering?
Direct Metal Laser Sintering (DMLS) is a powder-bed additive manufacturing technology that doesn’t require any tooling and is occasionally referred to as SLS (selective laser sintering) or SLM (selective laser melting). The process involves creating metal parts with simple to complex geometries directly from a 3D CAD (computer aided design) file. The DMLS software will then instruct the 3d printer to build the metal part or object layer by layer (between 20-40 microns thick) by fusing metal powder into a solidified state through a directional or focused laser beam.
How soon can I get my 3D printed metal part?
If we get your CAD file in "ready to print" state, then we can deliver your part in 10-15 business days if you are located in Canada or the U.S. Weather conditions may extend the delivery window.
What is the process of printing metal at Axis Prototypes?
1) Receiving your CAD file in .stl format | Show me how
2) Inspecting the CAD file to ensure compatibility with our DMLS 3d printing machine
3) Importing file into the 3D printer; set & configure parameters
4) Print via direct metal laser sintering
5) Post-processing treatment (if required)
What machine does Axis Prototypes use for its DMLS printing service?
We currently operate a EOS M270 metal sintering machine that can produce customized metal objects and end-use applications.
-M270: 9 x 9 x 7.5’’ (228 x 228 x 190 mm)
-Minimum feature size: 0.015’’ (0.38 mm)
-Minimum wall thickness: 0.3 mm - 0.4 mm (0.012” - 0.014”)
-Thickness of layer: 20 or 40 microns
-Typical tolerances: 0.005" on 1st inch, .002" thereafter
-Beam thickness: 0.008’’ (0.2032 mm)
-Build area: 250 mm x 250 mm x 325 mm (9.85 in. x 9.85 in. x 12.8 in.)
What can I produce using this 3d metal printing service?
DMLS changes the way we can approach design of parts. In the past, one would have to integrate manufacturing considerations while designing a part. There is virtually no limit as to what you can produce using DMLS, a tool-free manufacturing method that benefits numerous companies seeking to expedite their product development cycle while responding to market needs faster. Simply provide us with your CAD file and we’ll take from there. DMLS service quote
What services do you provide for finished metal parts and models?
We offer various post-printing treatments like electroplating. See above for more details.
What are the benefits of Direct Metal Laser Sintering?
What materials can be processed?
We currently offer in-house GP 1 Stainless Steel, PH1 Stainless Steel, and MS1 Maraging Steel. With our network of collaborators we are also able to assist you with other metals.
The range of materials that can be processed by DMLS can be found above.
When should I choose DMLS over other metal manufacturing methods?
If a part cannot be easily stamped, laser cut or machined on a CNC (multiple set-ups, multi-part assembly, complex geometries, curved inner channels) then it may be a candidate for DMLS 3D printing.
The design freedom that this technology provides allows you to optimize your design and functions to take advantage of the process capabilities. One of the case studies of a part used by a major aircraft engine manufacturer integrated about 15 individually manufactured parts into a single printed part. Consequently, the DMLS printed part is 25 % lighter, provides improved performance through curved inner channels and optimized flow, is more reliable, and represents a significant life-cycle cost reduction.
