Abstract
One embodiment of the invention provides a three-dimensional printing system includes a first projector, a second projector, and a solidification region. The solidification region accommodates a curable material and has a first area and a second area. The first projector projects a first image on the first area, the second projector projects a second image on the second area, and the first image and the second image are stitched together to form an image seam. The image seam is the only one overlapping area between the first image and the second image, and a width of the image seam is smaller than a span of five consecutive pixels arranged crossing the image seam.
Claims20
A three-dimensional printing system, comprising:
- a first projector;
- a second projector;
- and
- a solidification region for accommodating a curable material and having a first area and a second area, the first projector projecting a first image on the first area, the second projector projecting a second image on the second area, the first image and the second image being stitched together to form an image seam, the image seam being the only one overlapping area between the first image and the second image, and a width of the image seam being smaller than a span of five consecutive pixels arranged crossing the image seam.
A fabrication method of a three-dimensional printing system, comprising:
- providing a casing;
- providing a first projector and placing the first projector inside the casing;
- providing a second projector and placing the second projector inside the casing;
- projecting a first image by the first projector to a first area of a solidification region;
- and
- projecting a second image by the second projector to a second area of the solidification region, the first image and the second image being stitched together to form an image seam, the image seam being the only one overlapping area between the first image and the second image, and a width of the image seam being smaller than a span of five consecutive pixels arranged crossing the image seam.
A fabrication method of a three-dimensional printing system, comprising:
- providing a plurality of calibration patterns and a plurality of projection images of the calibration patterns, wherein each two adjacent calibration patterns form a pattern seam, and each of the projection images overlaps a neighboring pattern seam;
- and
- detecting positional deviation between each of the calibration patterns and a projection image corresponding to the calibration pattern to generate at least one position calibration file.
