MULTI COLOR INK FOR 3D PRINTING 3D PRINTER AND METHOD OF CONTROLLING THE 3D PRINTER

摘要

A multi color ink for 3D printing a 3D printer and a method of controlling the 3D printer are provided. The multi color ink for 3D printing including a first ink composition that includes a photocurable material a photoinitiator configured to cure the photocurable material a first colorant and an anti intercolor bleed agent configured to prevent intercolor bleeding occurring when the plurality of ink compositions come into contact with each other and a second ink composition that includes a photocurable material a photoinitiator configured to cure the photocurable material and a second colorant having an acid moiety involved in a reaction with the anti intercolor bleed agent to cause aggregation. The multi color ink for 3D printing may enable a clear image by inhibiting intercolor bleeding that occurs when ink compositions with different colors are printed to be adjacent to each other before curing during 3D printing.
