Direct Metal Laser Sintering

Definition

Direct Metal Laser Sintering (DMLS) is an additive manufacturing technology that uses a high-powered laser to fuse metal powder particles together to create complex metal parts layer by layer. This process allows for the production of intricate geometries and lightweight structures, making it popular in industries such as aerospace, automotive, and medical. DMLS is often employed by service bureaus to provide rapid prototyping and low-volume production of metal components.

5 Must Know Facts For Your Next Test

1. DMLS can produce highly complex geometries that are often impossible or impractical to achieve with traditional manufacturing methods.
2. The technology allows for minimal waste since it only uses the amount of powder needed for each layer of the part being produced.
3. DMLS is capable of working with a variety of metals, including stainless steel, titanium, aluminum, and cobalt-chrome alloys.
4. Parts produced using DMLS often require post-processing techniques like heat treatment or surface finishing to achieve desired mechanical properties and surface quality.
5. Service bureaus utilizing DMLS can offer rapid turnaround times for prototyping and small-scale production runs, making it an attractive option for companies looking to innovate quickly.

Review Questions
