TECHNIQUES FOR DESIGNING AND FABRICATING SUPPORT STRUCTURES IN ADDITIVE FABRICATION AND RELATED SYSTEMS AND METHODS

摘要

According to some aspects, techniques are described for generating support structures that may be easily removed after fabrication yet provide sufficient structural support during fabrication. In some cases, the techniques may include tuning an extent to which pillars of a support structure are interconnected to one another in regions proximate to the part. In some cases, the techniques may include fabricating very small contact structures, referred to herein as “hair” supports, in regions of a support structure where it connects with the part. In some cases, the techniques may include generating support structures that comprise obliquely-angled tips, which allow forces during fabrication to be applied in a preferred direction even when the support structure does not make a connection to the part in the preferred direction.
