Direct Metal Laser Sintering from CONCEPT LASER

Direct Metal Laser Sintering (DMLS) uses a precise, high-wattage laser to micro-weld powdered metals and alloys to form fully functional metal components from your CAD data. DMLS eliminates time-consuming tooling, and creates complex geometries not possible with other metal manufacturing processes. Made from materials like Inconel, Aluminum, Stainless Steel, and Titanium, DMLS parts are strong, durable, and heat-resistant. DMLS parts are also denser than investment casted metal parts. This accurate metal 3D printing process provides fine feature detail, making it ideal for complex oil and gas components, custom medical guides, consolidated aerospace parts, and tough functional prototypes.

Benefits of DMLS

Design Freedom

Build real metal parts without conventional manufacturing limitations. With DMLS, you can create durable, intricate metal parts that until now, were difficult or impossible to fabricate with other manufacturing processes.

Streamlined Manufacturing

Consolidate design and optimize value. As a 3D printing technology, DMLS allows you to integrate multiple components – such as mountings, fasteners, and sectioned parts – into a single, strong metal part. This reduces weight, cuts down waste, and saves the time and resources needed for assembly.

Functional Parts, Fast

Cut lead times and get results. From prototypes to low-volume production parts, DMLS can accelerate your project’s design and manufacturing timeline. Build tough, hard-working prototypes to test components in real-world applications, and eliminate time-consuming tooling for low-volume production parts.

DMLS Applications

DMLS is a great solution for complex metal parts you can’t build with conventional manufacturing technologies.

Common applications include:

  • Parts with cavities, undercuts, draft angles
  • Fit, form, and function models
  • Tooling, fixtures, and jigs
  • Conformal cooling channels
  • Rotors and impellers
  • Complex bracketing

Stereolithography

Stereolithography (also known as SL or SLA) builds parts layer-by-layer using a UV laser to solidify liquid photopolymer resins. It is commonly used to produce concept models, master patterns, large prototypes and investment casting patterns.


Stereolithography (SL) Applications

SL is often used for prototypes or large concept models that require coatings or finished surfaces and smooth master patterns.

Common applications include:

  • Anatomical models
  • Lightweight concept models
  • Architectural models
  • Urethane casting patterns
  • Large investment cast patterns

Laser Sintering

Laser Sintering (also known as Selective Laser Sintering, SLS or LS) uses a CO2 laser to heat and fuse durable thermoplastic powder to build versatile parts with high elongation at break. LS production parts and prototypes provide lightweight, heat and chemical resistant solutions.

LS Applications

LS is excellent for functional prototyping or production parts in a variety of taxing environments.

Common applications include:

  • Ductwork
  • Fuel tanks
  • Control surfaces
  • Flight-certified parts
  • Brackets, clips, clamps
