Introduction
Sintering is the process by which bonding between common particle can be obtained.
Selective Laser Sintering a Rapid Prototype
technology.
SLS is advance manufacturing process with use of powerful software
SLS process capable of producing complex parts
Shrinkage compensation
result to compensate shrinkage
Laser exposure should be along hatching
Part should be oriented along with X axis of chamber
Select beam compensation factor properly
Shrinkage along direction is more than across scanning
Effect of laser sintering parameter
Mechanical properties obtained depends on energy density given.
Laser power and scan speed does affect the properties.
If the energy density constant for different laser power and scan speed the mechanical properties obtained are constant.
If energy density is different mechanical properties are also different.
CONCLUSION
SLS is advance manufacturing process capable of producing complex parts with accuracy
SLS allows to use different combination of materials.
The mechanical properties obtain depends only on energy density not on laser parameter.
Shrinkage affect the accuracy of parts to compensate use the different building strategies
We should use liquid state sintering with coated grain to bind the particle properly.
