“…Using box joints with stiff material sheets for personal fabrication is explored by the creators of easy‐to‐use tools like Platener [BGM*15] and kyub [BSK*19], which creates shapes from voxel‐like cells. Their follow‐up works address topics like reinforcement of weak structures (fastForce [ATK*21]), intuitive layouts of the flattened pieces for easier assembly (Roadkill [ASS*21]) and automatic adjustments corresponding to the width of the kerf cuts [RAS*20, KTA*23].…”

Fast, flexible, and cost efficient production of 3D models from 2D material sheets is a key component in digital fabrication and prototyping. In order to achieve high quality approximations of freeform shapes, a common set of methods aim to produce bendable 2D cutouts that are then assembled. So far bent surfaces are achieved automatically by computing developable patches of the input surface, e.g. in the context of papercraft. For stiff materials such as medium‐density fibreboard (MDF) or plywood, the 2D cutouts require the application of additional cutting patterns (“kerfing”) to make them bendable. Such kerf patterns are commonly constructed with considerable user input, e.g. in architectural design. We propose a fully automatic method that produces kerfed cutouts suitable for the assembly of freeform shapes from stiff material sheets. By exploring the degrees of freedom emerging from the choice of bending directions, the creation of box joints at the patch boundaries as well as the application of kerf cuts with adaptive density, our method is able to achieve a high quality approximation of the input.
