The emergence of low-cost 3D printers steers the investigation of new geometric problems that control the quality of the fabricated object. In this paper, we present a method to reduce the material cost and weight of a given object while providing a durable printed model that is resistant to impact and external forces. We introduce a hollowing optimization(More)
We pose the <i>decompose-and-pack</i> or <i>DAP</i> problem, which tightly combines shape decomposition and packing. While in general, DAP seeks to decompose an input shape into a <i>small number</i> of parts which can be <i>efficiently</i> packed, our focus is geared towards 3D printing. The goal is to optimally decompose-and-pack a 3D object into a(More)
