Safety Precautions - HP Metal Jet S100 User Manual

NOTICE: Throughout the printing process, the powder bed may be heated—as shown by the Energy
element—to evaporate volatile components and cure the HP Binding Agent.
Stages of the process
● Spread powder: The build begins with a scanning recoater laying down a uniform, thin layer of metal
powder across the working area. The recoater is refilled from supply bins of powder located at each
end of the scan. This enables bi-directional recoating for increased productivity.
● Print agent: HP printheads jet HP Binding Agent at precise locations onto the powder bed to define
the geometry of single or multiple parts. At one end of the scan, a printhead service station tests,
cleans, and services the printheads for reliable operation.
● Evaporation: The liquid components of the HP Binding Agent evaporate.
● Retract the bed, print next layer: The powder bed is retracted the thickness of the printed layer, and
the process repeats until the build is completed.
●
Cure the bed: The powder bed with its printed parts is heated to complete the evaporation of liquid
components from the HP Binding Agent and to cure the polymers to achieve strength in the green
part(s).
● Unpacking: The powder bed is now cooled, and parts can be removed. Unpacking is the process
of removing loose powder from the surfaces of the part. Once the parts have been unpacked
and removed, the remaining powder can be processed and reused for economical consumables
management.
● Sintering: The green parts are now moved into a furnace. At sintering temperatures, atomic diffusion
at the surfaces of the metal particles binds them.
● Finishing: The part(s) may now undergo machining and polishing to meet dimensional and surface-
finish requirements.
