DMLS Additive Metal Manufacturing

Burloak Technologies' AMM (Additive Metal Manufacturing) process utilizes state of the art DMLS (Direct Metal Laser Sintering) systems to produce prototype, production and replacement parts directly from digital data using a process referred to as DDM (Direct Digital Manufacturing) to deliver fully dense components in a wide range of metals in a matter of hours rather than the weeks and sometimes months offered by traditional methods.

Additive Metal Parts

By building parts one layer at a time, our DMLS systems allow the creation of complex features within parts that would be impossible to produce with traditional subtractive manufacturing methods. These complex geometries can include features such as fully conformal heating and cooling channels in molds, dies and turbo components, complex heat exchanger geometries, and lightweight componentry with extremely thin wall sections.

Another key benefit of our AMM process is the ability to dramatically improve designs by combining multiple components within an assembly into a single component thereby reducing manufacturing costs, eliminating assembly costs and risks and allowing for much lighter and potentially more efficient designs.

Why should I choose Additive Metal Manufacturing?

  • Widest range of materials available
  • Material properties similar to wrought product delivering strong accurate parts
  • 100% Dense material
  • Minimal waste – You are only paying for the net part weight
  • Very fine details possible
  • Extremely complex internal geometries
  • Lightweight designs
  • Quick delivery of components
  • No need for expensive tooling and fixtures

What are some typical additive metal part applications?

  • Aerospace components
  • Spaceflight components
  • Turbine and Turbo compressors
  • Heat Exchangers
  • High temperature component applications
  • Tool & Die inserts with conformal cooling and heating
  • Medical Instruments, Surgical Guides, Medical Implants
  • Racing and lightweight performance parts
  • Low to medium volume high quality functional parts on demand
  • Direct Digital Manufacture of serial parts
  • Rapid Prototyping
  • Quick delivery of replacement parts

What metals can be used?

Burloak can obtain powders and develop production processes for most metals. We are always researching new metals to continually meet customer needs. The following metals are considered standard:

  • Titanium Ti6Al-4V-ELI
  • Inconel IN625
  • Inconel IN718
  • Aluminum ALSi10Mg
  • Maraging Steel MS1
  • Stainless Steels 15-5 SS 316
  • Cobalt Chrome SP2
  • Invar 36 & 32-5
  • Copper

How can parts be finished?

Burloak has complete capability to finish AMM components with high precision multi-axis CNC machining. AMM components can be CNC machined in the same manner as traditionally forged, bar and cast materials but with AMM we are usually able to produce parts that are much closer to net shape, and in many cases at net shape, direct from the 3D printing process.

  • Microscopic deburring
  • Microscopic polishing (internal and external)
  • Shot peening
  • Plating
  • Honing
  • Lapping
  • Heat treatment
  • Painting

How are parts inspected for quality?

Our Full Metrology Lab complete with CMM, laser scanning and metallurgical experts ensure production parts meet exacting specifications.
