Metal 3D Printing (DMLS) Services

Direct Metal Laser Sintering (DMLS), also known as Selective Laser Melting (SLM), is a metal 3D printing technology that selectively fuses a fine metal powder in aluminium or stainless steel. This 3D printing technology is used to manufacture both prototypes and production parts, especially with very complex features and all-in-one assemblies.

Pros & Cons of DMLS 3D Printing

Advantages Considerations
Complex Geometries: DMLS makes it possible to manufacture parts that cannot be produced with subtractive manufacturing Surface roughness is higher than with CNC machining
Powdered metals used for DMLS 3D printing possess strong mechanical properties Higher costs than other manufacturing technologies
Variety of mechanical and electro-chemical post-processing options applicable for final part enhancement Limited volume size

Lead time 5 days 3 days 3 days 3 days 5 days 3 days 7 days
Build volume 250 x 250 x 325 mm up to 380 x 284 x 380 mm, while we normally recommend the maximum size of 356 x 280 x 356 mm up to 736 x 635 x 533 mm up to 914 x 610 x 914 mm up to 119 x 189 x 300 mm. Recommended size: Within 100 x 100 x 150 mm up to 340 x 340 x 605 mm, but usually, we recommend the maximum size of 320 x 320 x 580 mm up to 490 mm x 391 mm x 200 mm
Layer thickness 0.02 – 0.08 mm depending on the material ~0.08 mm min 0.02 ~0.05-0.3 mm ~0.1 mm ~0.1 mm and for water-tight parts 1.5 mm, when wall thickness is higher 0.004 mm
Minimum feature size 0.75 mm for cosmetic features, 1.5 mm for structural features min 0.5 mm, 0.7 is recommended 0.1 mm up to 0.2 mm min 1 mm is recommended min 0.5 mm, 0.75 is recommended 1.2 mm or greater for rigid. 2 mm or greater for rubber-like
Tolerance ±0.2% (±0.1 – 0.2 mm) ±0.3% (± 0.2 mm) ±0.2% (± 0.2 mm) ±0.3% (± 0.3 mm) ±0.1% (± 0.1 mm). However, tolerances are not guaranteed on the first attempt at a new design. ±0.3% (± 0.3 mm) ±0.1 mm for the first dozens of mm is typical, plus ±0.05 mm for every mm thereafter
Description Metal 3D printing technology. Selectively fuses a fine metal powder in aluminium or stainless steel A technology that produces highly accurate and durable parts at fast speeds, especially compared to other powder bed fusion technologies A technology that produces extremely accurate and high-resolution parts Widely known for a great material selection, accuracy, and possibility to print large parts. A breakthrough technology that uses digital light projection, programmable liquid resins, and oxygen-permeable optics to produce parts with exceptional durability, resolution, and surface finish One of the most popular and inexpensive technologies for industrial 3D printing Polyjet is a rigid photopolymer 3D printing technology that produces high-detailed models.
