Fused Deposition Modeling (FDM)
Part of FDM
PLA (Polyactic Acid)
Easy-to-print with minimum warping or curling
Can withstand higher heat
Design for FDM
Need of Support
Feature overhung more than 45 degrees will need “support”
Bridge exceeds 5 mm will result in sagging or marks from support material
Selective Laser Sintering (SLS) Technology
The process of SLS
Process begins with the atmosphere in the process chamber heated
to the operating temperature and chamber filled with nitrogen.
Characteristics of SLS Parts
Rough surface finishes and porous.
Advantages of SLS
Excess powder material can be returned to the powder
Ability to provide self support during building.
Stereolithography (SLA) Technology
How part is make ?
The machine begin by build the part one layer at a time
