Abstract: 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 adjusting the shapes of members of a support structure proximate to a join between the members so that the cross-sections of the members have conformal edges.
