market. The technology can build multiple
parts in a matter of hours, enabling
product development teams to receive
imperative feedback, revise, and reiterate
within days. PolyJet is most efficient for
small, detailed parts. Designs within a 5
to 6-in. cubed area leverage the speed,
surface finish, detail and low price point
of PolyJet.Geometric freedom
3D printing gives you freedom to design.
Traditional design for manufacturability
rules don’t apply because the technology
can build complex geometries with
cavities, undercuts, overhangs and more.
What may have been an impossible design
to machine is now feasible. You have the
freedom to let function and performance
be the main drivers of design, rather than
cost, time or the limitations of traditional
manufacturing methods.PolyJet can deliver a minimum feature
size of 0.012 in. and layer thicknesses as
thin as 27 microns (thinner than human
hair). Because the 3D printing process
doesn’t use heat to fuse layers together,
warping and shrinking are not a concern.
A designer can take advantage of the
technology’s build features to create finely
detailed prototypes unburdened by the
constraints of traditional manufacturing.Full color
One of the biggest challenges designers
face when prototyping is meeting the
seemingly contrasting needs for an
accurate, aesthetic model that is also
delivered quickly. In addition to being fast,
PolyJet technology produces cosmetic
parts in full color.
PolyJet offers a full range of CMYKW
color options – 360,000. Graphics and
pictures can be incorporated via images
