DMLS MATERIALS

Aluminum


The current grade of the DMLS aluminum material is comparable to an A356 cast alloy and possess good mechanical properties. In addition to Titanium 64, aluminum offers light-weight versatility and is robust enough for prototype and production applications. DMLS aluminum is also well suited for parts that have thin walls and still need good thermal properties.

Applications

  • Short-run production
  • Space & Aerospace
  • Automotive
  • Prototyping R&D

Cobalt Chrome


This unique DMLS material falls under the classification of a superalloy and exhibits excellent strength and density. It also has optimal HDT and is corrosion resistance. It is commonly used for implantable applications and, broadly used for high-temp aerospace applications, including rig testing.

Applications

  • Orthopedics
  • Aerospace engine rig testing
  • High-temp environments
  • Nickel-free material applications

Cobalt Chrome SP2


In the dental industry, laser sintering using Cobalt Chrome SP2 has become an emerging process and material for producing DMLS-made dental crowns and bridges at dental labs throughout the world. As the DMLS process becomes even more accurate, usage in the dental industry is expected to grow.

Applications

  • Biocompatible applications
  • CE-certified for CE 0537
  • Print on demand
  • Customized patient usage

Inco 625


Many independent studies have confirmed that laser sintered Inco 625 & 718 actually produce DMLS parts with better properties than traditionally manufactured investment cast parts. Inco 625 is a nickel-chromium alloy and exhibits high creep and tensile strength. According to EOS, DMLS Inco 625 has a chemical composition corresponding to UNS N06625, AMS 5599G, W.Nr 2.4856, DIN NiCr22Mo9nb.

Applications

  • Aerospace
  • Combustion & propulsion
  • Suitable in corrosive environments
  • General Prototyping

Inco 718


Like Inco 625, independent studies have shown that Inco 718 also produces DMLS parts with better material properties than cast parts. DMLS Inco 718 is well suited for cryogenic applications, and performs exceptionally well in high-temp environments. According to EOS, its composition corresponds to UNS N07718, AMS 5662, AMS 5664, W.Nr 2.4668, DIN NiCr19Fe19NbMo3.

Applications

  • Propulsion & combustion applications
  • Engine & rocket components
  • Suitable in corrosive environments
  • Drilling and testing

Maraging Steel MS1


Widely used for conformal cooling applications, MS1 is favorite for DMLSing parts that need to be placed in production molds. This martensite-hardenable steel polishes exceptionally well and has profound robustness, achieving a 54 HRC. DMLS MS1 parts are also easily machinable and can also be EDM.

Applications

  • Conformal cooling inserts
  • Wind tunnel testing
  • Tooling applications
  • Robust, highly polishable parts

Stainless Steel 17-4


One of the first materials to enter the DMLS marketplace, 17-4 SS offers excellent producability and perfect for general prototyping or instrumentation applications. Unlike its sister material, 17-4 PH, 17-4 SS achieves only a 26 HRC, but processes very quickly and produces excellent quick-turn prototype parts.

Applications

  • Functional prototypes
  • Surgical instrumentation
  • Detailed components
  • Medical device applications

Stainless Steel 17-4 PH


Best suited for parts that need to be in a stainless but with a higher Rockwell then what 17-4 SS offers. DMLS 17-4 PH achieves an outstanding 40 HRC after heat treat and conforms to the compositions of 15-5 PH. 17-4 PH processes as well as 17-4 SS and is excellent for producing quick prototypes or production parts.

Applications

  • Short-run production
  • Surgical tools
  • Robust stainless applications
  • Larger-sized DMLS parts

Stainless Steel 15-5 PH


If better corrosion resistance is needed, DMLS 15-5 PH is ideal than other martensitic stainless steels. Its strength and toughness can be altered by further temperate range when heat treated. Among commercially available alloys, 15-5 PH is less used than 17-4 or 17-4 PH, but is easy to process and works well for the right applications

Applications

  • Valves
  • Aircraft Parts
  • Gears
  • Pump Parts

Stainless Steel 316L


Chromium-Nickel stainless steel is the latest commercially available stainless grade DMLS material and processes as easily as 17-4 stainless steel. 316L stainless steel provides increased strength at elevated temperatures and are similar to those of 304. DMLS 316L is an extra-low carbon version than that of 316, which minimizes carbide precipitation due to welding.

Applications

  • Aerospace engine parts
  • Marine products
  • Weldments
  • Pharmaceutical designs

Titanium 64


DMLS Titanium 64 is a Ti6Al4V alloy and is available in ELI and CP Grade 2 powder. The most common commercially available is grade 4. Ti64 is excellent for light-weight applications while maintaining ideal mechanical properties and corrosion resistance. According to LPW USA, Ti64 fulfills requirements of ASTM F1472 (for Ti6Al4V) and ASTM F136 (for Ti6Al4V ELI) regarding maximum concentration of impurities.

Applications

  • Aerospace
  • Spine & Orthopedics
  • UAVs
  • Biomedical Implants
