Question

sls: new developments
use the information below to answer the question.
there are three new developments in sls printing related to its price, sizing, and technology.

price
regular machines cost $18,000 to $32,000. a do-it-yourself desktop model is now available for $6,000.

size
the build volume is becoming smaller. the powder bin for a full-size industrial printer is 300 x 300 x 300 millimeters. with many of the new desktop models, the build volume is about a third of that size: 100-150 millimeters per side.

technology: heat source
with larger sls printers, a co₂ laser provides the heat for sintering the powder together. the smaller models use an optic fiber system, which is not as hot. there are also some printers that use a led laser rather than a co₂ laser. this increases the heat of the beam and creates more detailed parts. this is a good option for highly specialized projects that require high accuracy and very fine detail

what is the build volume for new desktop sls models?
150-200 millimeters per side
200-250 millimeters per side
100-150 millimeters per side
300-400 millimeters per side

Explanation:

To find the build volume for new desktop SLS models, we refer to the "Size" section of the provided information. It states that the build volume for new desktop models is about a third of the full - size industrial printer's powder bin (which is 300 x 300 x 300 millimeters) and is 100 - 150 millimeters per side.

Answer:

100 - 150 millimeters per side
