Question

bj: printer characteristics
use the information below to answer the question
the binder jetting (bj) printer is a combination of the sls machine and the material
jetting machine. it has a powder bed, but it doesnt have a heat source. the print is
made using a binding agent.
build volume
like sls printing, there is a powder bin. the full capacity of the build volume can be
utilized for low - to - medium run productions of 50 to 100 pieces.
benefits
· since there is no heat source, there is no tension between hot and cold spots,
which can lead to warping or delamination.
· many organic and complex geometries can be created because it doesnt require
support materials.
· prints can be more durable because there is no issue on removing support
structures.
limitations
· the powder and unfused powder between parts can be a hazard, which requires the
use of proper safety equipment.
a binder jetting (bj) printer is a combination of which two types of machines?
the vat and stereolithography machines
the fff and sls machines
the dlp and fused filament fabrication machines
the sls and material jetting machines
