How it Works• Photocurable resin• Very fine layer lines/
resolution• 0.00063” resolution on Z axis
• Minimum feature size is
around 0.012”• 0.060” minimum thickness for
some designs/ materials

FDM utilizes heated thermoplastic filaments in a semi-liquid state and extrudes those filaments in computer determined designs one layer at a time. FDM has one of the larger
build platforms or any 3D print technology at 36” x 24” x 36”

Metal and metal alloys in powder form are sintered – heated and fused – together in a process akin to a very fine, precise welding to create durable, highly complex fully dense metal parts which would be impossible to achieve through conventional manufacturing.

• Challenge: Doctors required patient skull models to better prepare for procedures
• Solution: PolyJet’s fine layers build extremely accurate models with smooth surfaces
• Results: Surgeons have in-depth knowledge of patient’s skull structure prior to performing operation

Challenge: SF Opera House sought to
recreate their iconic chandelier as a
collectible item available in their gift shop.
Solution: Inkjet-Based printing with PolyJet
High Definition (HD) resulted in ideal,
highly detailed and accurate renderings of
the chandelier design. Jersey McDermott,
craftsperson with San Francisco Opera
Costume Shop, used the PolyJet HD prints
as master patterns to create detailed
cufflinks and necklaces.
Results: Stunning portrayals of the iconic
San Francisco Opera Chandelier which
guests can take home with them and
cherish.
