Abstract
Provided herein are systems, apparatuses, and methods for generating a three-dimensional (3D) object using an energy beam array. Also provided herein are systems, apparatuses and methods for generating a 3D object with small-scaffold features, as well as systems, apparatuses and methods for generating a 3D object using roll-to-roll. The roll-to-roll apparatus may include a moving platform of the 3D object. The 3D object can be formed by an additive manufacturing process from a material such as powder.
Claims26
A method for generating a three-dimensional object, comprising:
- (a) providing a material bed comprising a material for use in generating at least a portion of the three-dimensional object;
- and (b) transforming at least a portion of the material in the material bed using a plurality of energy beams from an energy beam array to form a hardened material, which transforming comprises subjecting the plurality of energy beams to relative motion with respect to material bed along a vectorial path, wherein the hardened material forms at least a portion of the three-dimensional object.
