System and method for high throughput three-dimensional printing

A method for 3D color printing of an object, the method comprising:

• slicing a 3D model of the object;
• adding color data to slices of said 3D model;
• and
• printing said slices with a printing block including a plurality of channels, said plurality of channels including channels each with a different colored building material and a channel with a clear building material, wherein said printing includes dispensing at each target location of a travel of said printing block, two at least partially overlapping droplets of building materials from respective two channels of said plurality of channels, said two channels per target location being selected based on said color data,
• wherein at least one of said slices is defined over a plurality of pixels, wherein at least one of said pixels defines a pair of colors, and wherein said two at least partially overlapping droplets of building material are selected based on said pair of colors of a respective pixel.

• and
• printing said slices with a printing block including a plurality of channels, said plurality of channels including channels each with a different colored building material a channel with a clear building material, and two channels with support material;
• wherein said printing includes:
• dispensing at each target location of a travel of said printing block, two at least partially overlapping droplets of building materials from respective two channels of said plurality of channels, said two channels per target location being selected based on said color data,
• dispensing said support material from each of said two channels of support material at a third target location of said travel, and
• dispensing both said support material from one of said two channels and one of said colored building material at a fourth target location of said travel.

• wherein said channels with different colored building materials includes cyan, yellow, magenta, white and black modeling material, and wherein said white modeling material includes a higher pigment concentration as compared to at least one other colored modeling material to compensate for color dilution when adding clear modeling material to target locations defined to include white modeling material.
