3D Metal Printing - DMLS - DMLM

i3D MFG™ is a 3D metal additive manufacturer specializing in production parts. We stock a wide variety of metals not commonly found at other DMLS manufacturers. One of i3D’s strengths is our expertise in using our open parameter set for our equipment to push our DMLM machines to achieve better surface finishes, create difficult geometries and create custom density and porosity settings. Our engineers focus exclusively on 3D metal printing and have developed extensive tribal knowledge around DMLS/DMLM design and strategies for best success.  i3D MFG™ is the additive manufacturing pathway for our customers to disrupt their market.

DMLM Metal Powders

Material Process Applications

i3D MFG™ specializes in advancements in DMLM (Direct Metal Laser Melting) metal powder development, iterative process refinement, and production applications. Our unique focus on production solutions prompted EOS to make us their MPA (Material Process Applications) partner.  i3D MFG™ invested in tools and partnerships that allow us to create custom metal powders and the corresponding computer programs (parameter sets).


Direct Metal Laser Sintering M290

i3D MFG™’s EOS M280 and M290 Direct Metal Laser Melting (DMLM) machines use 20 to 60 micron powders and 400W lasers to fuse micro-layers of fine metal together at specific points directed by a 3D Solidworks design file to produce production parts. DMLM parts are typically characterized as having strength, hardness and durability that is, at the least, comparable to cast or forged parts in a comparable metal.

Production AM

EOS M400.4

Metal Additive Manufacturing is more than proof of concept or prototype. The technology itself produces fully dense, production quality parts. With the EOS M4004., quad laser DMLM machine, speed and cost efficiencies are also now a reality in Metal AM. i3D MFG utilizes its EOS M400.4 to run production parts for a variety of industry projects. Each of the 4 quadrants is able to build simultaneously what a single M290 builds, resulting in three and half times more parts in the same build time.


Electrical Discharge Machining

Electrical Discharge Machining (EDM) is a precision manufacturing process through which, a desired shape is cut to held tolerances of up to +/- .001mm using electrical discharges across a fine wire. With minimal set-up time for intricate cutting patterns, the CUT 30P is a perfect complimentary manufacturing process.  Many of our customers have found that their less complex, but high tolerance parts are well-suited to production on the Wire EDM.

i3D MFG™ offers one of the largest selections of DMLS standard metal powders in the U.S. We are one of the few 3D manufacturers specializing in Titanium and Inconel and are the EOS North America MPA (Material Process Applications) partner specializing in custom metal powder applications. Our engineers are experts in Design-for-3D strategies, enabling our customers to realize significant competitive advantages in design and proprietary advancements.

How 3D Metal Printing Works

Metals We Print

Aluminum (Al)

AlSi12 is our most common DMLS Aluminum powder and is perfect for projects with good thermal and low weight considerations.  It is an optimal metal for parts with thin walls and complex geometries.

Titanium (Ti)

Ti64 is the standard DMLS powder which is well suited for Medical, Aerospace, Firearms, Energy and Automotive projects requiring corrosion resistance, strength, weight reduction and biocompatibility.

Stainless Steels

PH1 is a medical grade, sterilisable, corrosion resistant steel. It is primarily used in Medical, Firearms, Energy and Automotive applications. After heat treatment, PH1 hardens to 40-45 HRC. Our stainless steel equivalents include 15-5, 17-4, and .316. Parts made from EOS StainlessSteel PH1 can be machined, spark-eroded, welded, micro shot-peened, polished and coated if required

Maraging Steel

Our Maraging steel powder has excellent strength and mechanical properties. MS1 is a pre-alloyed, ultra high strength steel powder most commonly used for tooling applications. Its chemical composition corresponds to U.S. 18% Ni Maraging 300, European 1.2709 and German X3NiCoMoTi 18-9-5. After heat treatment, MS1 typically has a 50-53 HRC

Inconels (Inconel 625 & 718)

IN718 is a DMLS nickel; A Chromium alloy with superior heat resistance and typical heat treatment hardness of 40-47 HRC (370-450HB).  Rocket, space, aerospace, firearms, energy, and automotive industries rely on Inconel.

Custom Powders

i3D MFG™ is the market leader is DMLS powder development. In addition to our established metallurgical partnerships, i3D™ is the first North American EOS Material Process Application (MPA) Development Partner, giving us access to the latest DMLS machine parameter sets and enabling i3D™ to develop highly specialized powder applications for aerospace, rocket, automotive, and casting customers
