  • LIQUID INKJETTABLE MATERIALS FOR THREE-DIMENSIONAL PRINTING
    Publication number: 20130026683
    Abstract: The present disclosure is drawn toward compositions, systems, and methods for printing of three-dimensional objects. In one embodiment, a liquid inkjettable material for 3-dimensional printing can comprise from 0.1 wt % to 10 wt % of a pigment, from 10 wt % to 90 wt % of a UV-curable polymer, and from 0.1 wt % to 70 wt % of a polymeric filler. Additionally, the liquid inkjettable material can be jettable from piezo electric inkjet printer nozzles and has acceptable decap performance measured by jetting a normal 50 picoliter ink drop within 10 electric firing pulses after the piezo electric inkjet printer nozzles have been fired and have been subsequently rested for 24 hours.
