Direct Metal Laser Sintering, Metal Selective Laser Sintering (SLS)
Direct metal laser sintering (DMLS) is an additive metal
fabrication technology developed by EOS out of Munich, Germany,
sometimes also referred to by the terms selective laser sintering
(SLS) or selective laser melting (SLM). The process involves use of
a 3D CAD model whereby a .stl file is created and sent to the
machine’s software. A technician works with this 3D model to
properly orient the geometry for part building and adds supports
structure as appropriate. Once this "build file" has been
completed, it is "sliced" into the layer thickness the machine will
build in and downloaded to the DMLS machine allowing the build to
begin.
1. DMLS is also one of the few additive manufacturing technologies
being used in
production. Since the components are built layer by layer, it is
possible to design internal features and
passages that could not be cast or otherwise machined.
2. Compared with traditional manufacturing techniques, the speed of
DMLS is the most
obvious because no special tooling is required and parts can be
built in a matter of hours.
3. Complex geometries and assemblies with multiple components can
be simplified to fewer parts with a
more cost effective assembly. DMLS does not require special tooling
like castings, so it is convenient for
short production runs.
4. DMLS allows for more rigorous testing of prototypes. Since DMLS
can use most alloys, prototypes can
now be functional hardware made out of the same material as
production components.
· Metal parts, fire test parts, fixture direct manufacturing and
model demonstration test.
· Development of new products.
· Creative design and display of culture, creativity, clothing,
household goods and other.
· Product design, rapid production of high-precision injection
molds.
· Research and development of implants, teeth, skull repair,
prosthetics and medical
equipment.
