The wide diffusion of 3D printing technologies continuously calls for effective solutions for designing and fabricating objects of increasing complexity. The so called "computational fabrication" pipeline comprises all the steps necessary to turn a design idea into a physical object, and this book describes the most recent advancements in the two fundamental phases along this pipeline: design and process planning. We examine recent systems in the computer graphics community that allow us to take a design idea from conception to a digital model, and classify algorithms that are necessary to turn such a digital model into an appropriate sequence of machining instructions.

Marco Attene is a permanent researcher at CNR-IMATI in Genova, where he studies geometry processing for 3D printing applications. He has a Ph.D., a research management diploma, and a full professorship habilitation. Marco has been the principal investigator at CNR for regional, national, and international projects, has or had collaborations and joint research programs with both industry and academy in Europe, the U.S., Asia, and New Zealand, and serves as an evaluator for research funding agencies. Marco has published high-impact articles in prestigious journals in the area, and contributed to the organization of international conferences as program chair, program committee member, and organizing committee member. He is an associate editor of international journals in the area and is an active software developer (his ""MeshFix"" system received the SGP Software Award in 2014). Marco is currently leading the ProcessPlanning work package in the EU H2020 project CAxMan on Additive Manufacturing.Marco Livesu is a permanent researcher at the Institute for Applied Mathematics and Information Technologies of the National Research Council of Italy (CNR IMATI). He received his Ph.D. at the University of Cagliari (2010âEUR"2014), after which he was a postdoctoral researcher at the University of British Columbia (2014-2015), University of Cagliari (2015), and CNR IMATI (2015-2016). His main research interests are digital modeling for manufacturing and mesh gen-eration. In 2015, he was one of the recipients of the ERCIM Alain Bensoussan PostDoctoral Fellowship. He is the creator and developer of CinoLib, a C++ library for processing general polygonal and polyhedral meshes. Marco is currently involved in the EU H2020 project CAxMan on Additive Manufacturing.Sylvain Lefebvre is a senior researcher at Inria (France). After a Ph.D. at Grenoble Alpes University (2002-2004), he joined Microsoft Research as a postdoctoral researcher in 2005 and Inria in 2006. His main research focus is to simplify content creation, synthesizing highly detailed patterns, structures and shapes, with applications in computer graphics and additive manufacturing. Sylvain received the EUROGRAPHICS Young Researcher Award in 2010 for his work on texturing data structures and runtime procedural texture synthesis. Since 2012, he has been the principal investigator of the ERC Shape-Forge project, which focuses on shape synthesis for additive manufacturing. He created and is the lead developer of the IceSL software for modeling for additive manufacturing. Sylvain is an active member of the community and serves on the technical papers committee and editorial boards of the main conferences and journals of the field.Thomas Funkhouser is a Professor in the Department of Computer Science at Princeton University. He received a B.S. in Biological Sciences from Stanford University in 1983, a M.S. in Computer Science from UCLA in 1989, and a Ph.D. in Computer Science from UC Berkeley in 1993. He has published more than 100 research papers and received several awards, including the ACM SIGGRAPH Computer Graphics Achievement Award. His research focuses on 3D shape analysis, geometric modeling, and scene understanding.Szymon Rusinkiewicz is a Professor of Computer Science at Princeton University. His work focuses on the interface between computers and the visual and tangible world: acquisition, representation, analysis, and fabrication of 3D shape, motion, surface appearance, and scattering. He investigates algorithms for processing geometry and reflectance, including registration, matching, completion, hierarchical decomposition, symmetry analysis, sampling, and depiction. Applications of this work include documentation of cultural heritage artifacts and sites, appearance and performance capture for digital humans, and illustrative depiction through line drawings and non-photorealistic shading models.Stefano Ellero is Project Manager at Stam S.r.l.He is a well-experienced mechanical engineer with expertise in design, engineering, prototyping and testing of mechanical devices, mechatronic systems, and production processes. He has strongly contributed to several developments of Stam in applications such as: automotive, bio-engineering, robotics, and aerospace. He is one of the inventors of the NUGEAR gearbox, use-case demonstrator of the CAxMan project, where Stam is partner and Stefano is actively involved.
