Robots and software have been significantly improving our daily lives by rendering us much
convenience. And 3D printing is a typical example, for it is going to usher in a new era of …

Recent work has demonstrated that the interior material layout of a 3D model can be
designed to make a fabricated replica satisfy application-specific demands on its physical …

We present a method for automatic generation of 3D models based on shape and topology
optimization. The optimization procedure, or model generation process, is initialized by a set …

Abstract 3D printing, also called additive manufacturing, has been increasingly popular and
printing efficiency has become more critical. To print artifacts faster with less material, thus …

Given the 2-manifold surface of a 3d object, we propose a novel method for the computation
of an offset surface with varying thickness such that the solid volume between the surface …

Offsetting-based hollowing is a solid modeling operation widely used in 3D printing, which
can change the model's physical properties and reduce the weight by generating voids …

This study presents the development of a novel MATLAB-based virtual prototyping tool
called Will It Print that evaluates part geometry to check for compliance with design-for …

Physical modeling is a novel theory for 3D printing; this approach involves the use of a
single material to control physical properties, such as center of mass, total mass, and …

The improvement and the massive diffusion of additive manufacturing (AM) techniques have
fostered the research of design methods to exploit at best the feature introduced by these …

Lattice structures have been widely used in various applications of additive manufacturing
due to its superior physical properties. If modeled by triangular meshes, a lattice structure …
