Abstract
Official abstract text for this publication.
Some aspects provide a method of generating a support structure for an object, the support structure and the object to be fabricated via one or more additive fabrication techniques, comprising identifying one or more regions of the object as one or more regions to which mechanical support is to be provided, identifying one or more support points within at least a first region of the one or more regions, and generating the support structure for the object, the support structure comprising one or more support tips coupled to the object at the one or more support points, the support tips being generated based at least in part on a direction normal to the surface of the object at the respective support point.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of generating a support structure for an object, the support structure and the object to be fabricated via one or more additive fabrication techniques, comprising: identifying one or more regions of the object as one or more regions to which mechanical support is to be provided; identifying one or more support points within at least a first region of the one or more regions; determining, for each of the one or more support points, a direction normal to the surface of the object; and generating the support structure for the object, the support structure comprising one or more support tips coupled to the object at the one or more support points, wherein an orientation of each of the support tips is determined based at least in part on the determined direction normal to the surface of the object at a respective support point, wherein the support structure comprises at least one scaffolding portion, and wherein at least a first support tip of the one or more support tips contacts the at least one scaffolding portion at a non-zero angle.
