3D printing is an emerging technology that has attracted much attention in recent years.The profound applications of this technology are likely to revolutionize many aspects of our life，ranging from rapid manufacturing，mass customization to health care devices.As discussed and demonstrated by the author，it is likely to make the third wave of industrial revolution.

The timely topics covered in this book provide an excellent introduction of topics related to 3D printing and the involved techniques.The author first gives a thorough review of the latest development of 3D printing and draw connections to the future of manufacturing in China.All the important techniques in 3D printing are then discussed and explained in the following chapters.In particular，the author uses 3D photography as an example to discuss it relevance to 3D printing.In addition，the author explains several computer vision algorithms on how to recover 3D model from images.The future of 3D printing is then discussed with numerous examples to motivate research problems for readers to ponder.For completeness，the author also discusses the underlying mathematics and algorithms related to 3D reconstruction.

In summary，this book provides an excellent introduction of the emerging and important topics of 3D printing.The discussed material not only cover topics of great interest to all readers but also algorithms for practitioners in computer vision.I highly recommend this book to readers interested in 3D printing or computer vision.
