Our DMLS 3D Printing Service

Direct Metal Laser Sintering or DMLS is an industrial metal 3D printing technology. It is a powder bed fusion process similar to SLS which builds parts from a range of metal materials one layer at a time by sintering metal powders together.

Maximum Build Size:
325 × 325 × 400 mm
Standard Lead Time:
7 business days
Dimensional Accuracy:
±0.2-0.3mm/100mm
Layer Height:
25-100 um

Advantages and drawbacks of DMLS 3D printing

Direct Metal Laser Sintering (DMLS) is a metal 3D Printing technology that selectively fuses a fine metal powder using a laser. This DMLS 3D Printing process is used to manufacture both prototypes and production parts – particularly those with very complex features and all-in-one assemblies with high strength requirements.

ADVANTAGES

Printing an all-in-one assembly strengthens the finished part while reducing the weight and cost of production significantly.

Create parts at a high density

DRAWBACKS

The surface of the product is rough and requires post-processing

Manufacturing and maintenance costs are very high

DMLS 3D Printing Materials

Aluminum

Cobalt-Chrome

Inconel 718

Stainless Steel 316L

Titanium

Aluminum

Aluminum (AlSi10Mg) is comparable to a 3000 series alloy that is used in casting and die casting processes. It has good strength-to-weight ratio, high temperature and corrosion resistance, and good fatigue, creep and rupture strength. Material property values below are measured after stress relief.

Accura Xtreme Gray
Accura 7820
WaterShed XC 11122
MicroFine

Cobalt-Chrome

Cobalt-Chrome (Co28Cr6Mo) material is used in our DMLS process. It is a superalloy comprised primarily of cobalt and chromium, and is known for its high strength-to-weight ratio, excellent creep and corrosion resistance.

Inconel 718

Inconel is a high strength, corrosion resistant nickel chromium superalloy ideal for parts that will experience extreme temperatures and mechanical loading. Final parts built in Inconel 718 receive stress relief application. Solution and aging per AMS 5663 is also available to increase tensile strength and hardness. Material property values below are measured after solution and aging heat treatment.

Stainless Steel 316L

Stainless steel 316L is a workhorse material used for manufacturing acid and corrosion resistant parts. Final parts built in 316L receive stress relief application. Material property values below are measured after stress relief.

Titanium

Titanium (Ti6Al4V) is a workhorse alloy. The mechanical properties of Ti6Al4V are comparable to wrought titanium for tensile strength, elongation, and hardness. Final parts built in Ti6Al4V receive vacuum stress relief application. Material property values below are measured after stress relief.

Surface Finish Options for DMLS 3D Printing

Surface finishes can serve either a functional or aesthetic purpose. Surface finishes that serve both purposes are deemed cosmetic finishes, and are used for cosmetic parts. Producing cosmetic parts requires additional measures to minimize defects such as hang marks and scratches from tools.

Types

Details

Clear Coat

Clear cosmetic finish that can be applied to ABS-Like Translucent/Clear (WaterShed XC 11122) and PC-Like Translucent/Clear (Accura 60) materials.

Painting

After smoothing the part with sanding and polishing, parts can be painted with automotive-grade paint. Provide a pantone color with your quote request. We also offer soft-touch painting.

Plating

Electroless nickel plating can be used to achieve parts that are similar to cast aluminum or magnesium.

Dyeing

Dyeing is another method for adding color to 3D prints. This is faster option with a limited color selection, so is a more cost-effective choice than painting.

Decaling

Decaling can be used to add a logo or other graphics to boost cosmetics or function.

Polishing

We can polish parts to a mirror-like finish. If this is a requirement, we ask that you provide either a drawing or image that indicates your finish expectations.

Heat Treatment

Harden and strengthen metal 3D prints with multiple heat treatment options: NADCAP heat treatment, hot isostatic pressing (HIP), solution annealing, and aging.
