METHOD FOR PRINTING A 3D OBJECT IN A PHOTOREACTIVE COMPOSITION, AND PRINTER SUITABLE FOR IMPLEMENTING THE METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240051233 titled 'METHOD FOR PRINTING A 3D OBJECT IN A PHOTOREACTIVE COMPOSITION, AND PRINTER SUITABLE FOR IMPLEMENTING THE METHOD

Simplified Explanation

The patent application describes a method for printing a 3D object using a photoreactive composition volume. The method involves extracting a mosaic sequence from a 3D image, where each mosaic contains multiple solid areas with illuminated points. The mosaic sequence is projected in an axial direction inside the volume, creating multiple light areas corresponding to the solid areas of the projected mosaic. The distribution and number of illuminated points in each solid area are adjusted to achieve a desired axial resolution in the photoreaction of the composition block. The solid areas in the mosaic are distributed in a way that prevents the composition from reacting between the light areas associated with multiple solid areas.

  • The method involves extracting a mosaic sequence from a 3D image with illuminated points.
  • Each mosaic in the sequence contains multiple solid areas with illuminated points.
  • The mosaic sequence is projected in an axial direction inside the photoreactive composition volume.
  • The projected mosaic forms multiple light areas corresponding to the solid areas.
  • The distribution and number of illuminated points in each solid area are adjusted for desired axial resolution.
  • The solid areas are distributed in a way that prevents unwanted reactions between light areas.

Potential Applications:

  • 3D printing of objects with complex geometries and intricate details.
  • Manufacturing customized products with high precision and resolution.
  • Prototyping and rapid product development in various industries.
  • Creating artistic and decorative objects with intricate designs.

Problems Solved:

  • Overcoming limitations in traditional 3D printing methods that struggle with complex geometries and fine details.
  • Achieving high-resolution printing without compromising on speed and efficiency.
  • Enabling the production of customized and personalized products at scale.

Benefits:

  • Improved accuracy and resolution in 3D printing.
  • Increased design freedom and complexity in printed objects.
  • Enhanced efficiency and speed in the manufacturing process.
  • Cost-effective production of customized products.


Original Abstract Submitted

a method—for printing a 3d object, defined by a 3d image having multiple illuminated points, in a photoreactive composition volume—includes extracting from the image a mosaic sequence. each mosaic includes multiple solid areas, each including illuminated point(s). the mosaic sequence is projected in an axial direction, inside the volume, to form—from each projected mosaic—multiple light areas, each corresponding to a solid area of the projected mosaic. in the solid area of a mosaic, a number of illuminated points and the distribution of the illuminated points are adjusted so, when projecting the mosaic is into the volume, the light area corresponding to the solid area causes a photoreaction in an associated composition block with a desired axial resolution. in the same mosaic, the solid areas are distributed such that, when projecting the mosaic into the volume, the composition does not react between the light areas associated with the multiple solid areas.
