In one embodiment of the present invention, an escape hole generator creates escapes holes designed to facilitate removal of support and / or unprinted material generated inside enclosed hollows of three-dimensional (3D) digital models during 3D printing. In operation, the escape hole generator identifies a hollow included in the three-dimensional model and then selects optimized locations for escape holes.

Advantageously, automating escape hole generation enables efficient creation of hollowed 3D models that reduce 3D printing time and material usage compared to solid 3D model counterparts.

Methods of updating b-tree data structures (e.g., b*tree data structure) using search key insertion and deletion operations proceed from respective known states (e.g., respective canonical forms). These insertion operations include inserting a first search key into the b-tree by reconfiguring (e.g., pre-processing) a plurality of sibling nodes of the b-tree into a predetermined overloaded form having a shape that is independent of a value of the first search key to be inserted therein.
