A liquid electrophotographic ink is disclosed. The liquid electrophotographic ink includes a carrier liquid, a polymer resin, and a pearlescent pigment particle.
摘要:
Techniques to determine concentration parameters of conductive liquid electrophoretic (LEP) inks are illustrated herein. In an example, a layer of conductive LEP ink is formed on a developer roller using electrostatic forces acting on the conductive LEP ink. A current is generated in response to a voltage between a measurement electrode and a developer roller. The current flows through the conductive LEP ink layer.

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.
摘要:
A method for making polymer-encapsulated metallic ink particles is disclosed herein. An ethylene-based polymeric resin powder is formed, and is mixed with a metallic pigment powder to form a powder mixture. The powder mixture is melted to form a metallic polymer melt. A non-polar carrier is added to the metallic polymer melt to form a slurry. The slurry is processed in a microfluidizer.

The present disclosure provides for compositions, methods, and systems directed towards a liquid electrophotographic ink comprising a carrier fluid, a pigment, a first resin, and a stable cross-linkable resin that is solvated or swellable with the carrier fluid, where the stable cross-linkable resin does not undergo cross-linking until a temperature of at least 110° C. and, once cross-linked, does not melt until a temperature of at least 300° C.

摘要:
A dispensing system for an additive manufacturing includes a powder source that contains powder to form an object, and an array of nozzles positioned at a base of the powder source over a top surface of a platen where the object is to be formed. The powder flows from the powder source through the nozzles to the top surface. A respective powder wheel in each nozzle controls a flow rate of the powder. Each wheel has multiple troughs on surface of the wheel. When a motor rotates the wheel, the troughs transport the powder through the nozzle. The rotation speed of the wheel controls the flow rate. For solid parts of the object, the wheel rotates and allows the powder to be deposited on the top surface. For empty parts of the object, the wheel remains stationary to prevent the powder from flowing to the surface.
