3D Metal Printing – DMLM/DMLS

Specializing in production parts, i3D MFG is a 3D metal additive manufacturer that stocks a wide variety of common and uncommon metals. We utilize an open parameter set for our equipment to push our DMLM and DMLS, or direct metal laser melting and direct metal laser sintering, machines. This allows us to achieve better surface finishes, create difficult geometries, and create custom density and porosity settings. Our engineers focus exclusively on 3D metal printing and are extremely knowledgeable around DMLM and DMLS design and strategy. i3D MFG is the additive manufacturing pathway for our customers to disrupt their markets.

DMLM Metal Powders

Material Process Applications

i3D MFG specializes in DMLM metal powder development, iterative process refinement, and production applications. Our state-of-the-art tools and valuable partnerships enable us to create custom metal powders and corresponding computer programs, or parameter sets, to provide our clients with the exact product they need.

DMLM

Direct Metal Laser Sintering M290

Our EOS M280, M290, and M400 x 4 production Direct Metal Laser Melting machines use 20 to 60 micron powders and 400W lasers to fuse micro-layers of fine metal together at specific points. This process is directed by a 3D Solidworks design file to produce top-quality production parts. DMLS/DMLM parts are known for strength, hardness, and durability that is comparable to cast or forged parts in a similar 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 M400 x 4., quad laser DMLS/ DMLM machine, speed and cost efficiencies are also now a reality in Metal AM. i3D MFG utilizes its EOS M400 x 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.

EDM

Electrical Discharge Machining

In Electrical Discharge Machining (EDM), a shape is cut to held tolerances of +/- .001mm using electrical discharges across a fine wire. The CUT 30P is an ideal complimentary manufacturing process due to its minimal set-up time and ability to cut intricate patterns. The Wire EDM is ideal for the production of less complex yet higher tolerance components.

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
