Image Processing Method And System For 3D Printing

An image processing method for 3D printing, comprising the steps, executed by a computer, of:

• (a) projecting an initial image on a layer to be printed;
• (b) shifting said initial image in a first direction, wherein the initial image is shifted by a first distance from an initial position to a first limited position to obtain a first image, wherein said first distance is not greater than a length of one pixel of said initial image in the said direction;
• (c) fusing said initial image and said first image together to obtain a fused image;
• and
• (d) printing said fused image on said layer to be printed.

An image processing arrangement for 3D printing, comprising:

• a processor;
• and
• a memory coupled to said processor, wherein said memory stores computer program instructions executed by said processor and configured to:
• project an initial image on a layer to be printed;
• shift said initial image in a first direction, wherein the initial image is shifted by a first distance from an initial position to a first limited position to obtain a first image, wherein said first distance is not greater than a length of one pixel of said initial image in the said direction;
• fuse said initial image and said first image together to obtain a fused image;
• and
• print said fused image on said layer to be printed.
