CONTROLLING LAYER SEPARATION IN STEREOLITHOGRAPHIC FABRICATION

NºPublicación: US2018134029A1 17/05/2018

Solicitante:
DESKTOP METAL INC [US]

Resumen de: US2018134029A1

Systems, methods, and components are disclosed for controlling layer separation in stereolithographic fabrication of three-dimensional objects. Each layer of the three-dimensional object can be cured and separated in discrete portions to facilitate controlling forces in the layers of a three-dimensional object. For example, controlling curing and separation of layers of a three-dimensional object according to the systems, methods, and components disclosed can facilitate accurately forming the three-dimensional object from cured particle-loaded resins. More specifically, particle loading can decrease the shear strength of the cured resin and, thus, controlling the forces exerted on a given layer of a cured particle-loaded resin can be particularly useful for reducing the likelihood of deformation in a three-dimensional object including the particles. In turn, the accurately formed three-dimensional object including the particles can be densified to form a dimensionally accurate finished part.
