Abstract
Methods and apparatus for the fabrication of solid three-dimensional objects from liquid polymerizable materials at high resolution. A material is coated on a film non-digitally, excess material is removed digitally, by laser, leaving an image of a layer to be printed, and the image is then engaged with existing portions of an object being fabricated and exposed to a non-digital UV curing light source. Since the only part of the process that is digital is the material removal, and this part is done by laser, the speed of printing and the robustness of the manufacturing process is improved significantly over conventional additive or 3D fabrication techniques.
Claims9
A system, comprising a coating system configured to coat a substrate with a uniform layer of liquid polymerizable material and provide the coated substrate to a negative printing unit, the negative printing unit configured to remove portions of the liquid polymerizable material from the coated substrate and provide a resulting version of the coated substrate with remaining segments of the liquid polymerizable material to a sample building unit that is spatially separated from the negative printing unit, the sample building unit configured to engage the coated substrate with the remaining segments of the liquid polymerizable material that represents an image of a layer of an article under fabrication with a sample and cure said remaining segments of the liquid polymerizable material with ultra-violet (UV) light when the remaining segments of the liquid polymerizable material are in contact with the sample.
