| (SLS) Selective
Laser Sintering Prototype
Parts |
 SLS prototype parts are
similar to SLA prototype parts. The 3D CAD model
is sliced into thin cross-sections or layers. The
SLS technology uses an infrared laser to sinter
the layers together in a variety of thermoplastic
and metal powders. Models can be produced from
flexible plastics as well as rigid ones. The key
advantage of the SLS technology is its ability to
rapidly produce durable, functional objects for a
wide variety of applications, where finish is not
a concern. SLS prototypes can be sterilized via an
autoclave and work great for thermoform prototype
tooling. The SLS technology can hold tolerances of
+/- 0.005 of an inch and produce features as small
as 0.020 of an inch. |

of (SLS) Selective Laser Sintering part finishes
|
- Level
1 cleanup
build support removal on all part surfaces
- Level
2 cleanup
slice line and resolution removal on specified
surfaces (normally) outside surfaces, inside
and/or underside surfaces have a basic Level
1 cleanup.
- Level
2 cleanup for Painting
purposes consists of slice line and resolution
removal on specified surfaces (normally) outside
surfaces, inside and/or underside surfaces have
a basic Level 1 cleanup, outside surfaces are
primered for painting.
