is known as Selective
Laser Sintering (SLS®) for plastic parts, and
Direct Metal Laser
Sintering (DMLS) for metal parts. Both are rapid
prototyping and additive manufacturing processes
and produce layer-manufactured components and assemblies.
Also known as direct digital manufacturing and e-manufacturing,
these cutting edge technologies produce smooth,
accurate and very durable plastic and metal parts
while maintaining very tight tolerances.
With the tolerances
that are achievable and the durability these parts
offer, Laser Sintering has become the preferred
process of prototyping, and is quickly becoming
an acceptable and even conventional method of manufacturing.
The largest build
chamber size for plastic laser sintering (SLS) is
29” x 21.65” x 29.53”. Standard tolerances are +/-
0.005” for the first inch, and +/- 0.003” for each
The build chamber
for metal laser sintering (DMLS) is 9.85” x 9.85”
x 8”. Standard tolerances can range from 0.010”
to as fine as 0.003”.
