Better Be Running
Book: Better Be Running. Ronald Hollis.
URL = http://rapidmfg.org/
"“Better be Running” is the most complete intro to additive fabrication (3D printing, cast urethane production, and low volume injection molding) you can find. The book is an outgrowth of the author’s business, QuickParts, which provides a wide range of custom fabrication/rapid prototyping services and the practical expertise is evident.
Better Be Running is written in a conversational tone and provides an overview of each technology, clear direction on when to use it, when not to, and how much it will cost in time and money. It reads like a transcript of a lecture from a great manufacturing course and assumes very little prior knowledge. It is hard to find better detail on the processes described anywhere, including the equipment manufacturer’s websites. For example, it covers tips like how to orient parts in various machines to get superior results. One criticism is that the book only covers technologies offered by Quickparts and leaves out laser cutters and other tools that may work better for a given job."
