Stainless Steel 3D Printing Stereolithography Rapid Prototyping
Technical Overview of Selective laser sintering (SLS)
The DMLS machine uses a highpowered 200 watt Ybfiber optic laser.
Inside the build chamber area, there
is a material dispensing platform and a build platform along with a
recoater blade used to move new
powder over the build platform. The technology fuses metal powder
into a solid part by melting it locally
using the focused laser beam. Parts are built up additively layer
by layer, typically using layers 20
micrometres thick. This process allows for highly complex
geometries to be created directly from the 3D
CAD data, fully automatically, in hours and without any tooling.
DMLS is a netshape process, producing
parts with high accuracy and detail resolution, good surface
quality and excellent mechanical properties.
· Product design, rapid production of high-precision injection
molds.
· Metal parts, fire test parts, fixture direct manufacturing and
model demonstration test.
· Research and development of implants, teeth, skull repair,
prosthetics and medical
equipment.
· Development of new products.
· Creative design and display of culture, creativity, clothing,
household goods and other.
