Chapter one shows the reader how to take photos of an actual object and stitch them up with 123D Catch to make a 3D model. I enjoyed reading chapter three which shows how to install a David Laserscanner using a webcam and a common laser to scan small objects. I also found clear images of host interfaces like Repetier which you install on your computer to control your printer. The author also compares slicing programs Slic3r and Skeinforge interface as well photos of the printed results.
Richard describes 3D modeling with TopMod to create organic forms with carefully designed support meant to be strong and easier to remove from the printed model which is knowledge that can only be gained by experience. He shows how to fix mesh problems with MeshLab for manifold issues, inverted mesh, as well as reducing the amount of polygons of dense models. He adds textures to his lovely starfish model with meshmixer. The author shows the lattice technique to prevent printed filament from curling up and distorting the model. He also discusses trouble shooting the actual 3D printer and common issues like a loose heatsink.
