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 $10,000 to $12,000. a do-it-yourself desktop model is now available for $6,000.

sizing
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 fast. there are also some printers that use a co 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 are do-it-yourself desktop sls models now worth?
$10,000
$12,000
$6,000
$4,000
