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 co laser rather than a co₂ laser. this increases the heat of the beams 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 size of the powder bin for a full-size industrial sls printer?
300 × 300 × 300 millimeters
100 × 100 × 100 millimeters
200 × 200 × 200 millimeters
400 × 400 × 400 millimeters

Explanation:

We refer to the "Size" section of the given information about SLS printing. It states that the powder bin for a full - size industrial printer is 300×300×300 millimeters.

Answer:

300 × 300 × 300 millimeters
