Key points

• Digital fabrication is a family of technologies that generate 3-dimensional, solid objects under computer control. They allow manufacturing engineers and designers to “print” their 3-dimensional designs in order to test and improve their ideas, and they allow manufacturers to produce complex machine parts quickly and accurately with minimal human labor. The machines, called “digital fabricators” or “fabbers” for short, operate by either (a) a subtractive process that removes material from a solid block, (b) an additive process that builds objects up one particle or one layer at a time, (c) a formative process that bends or presses a sheet or soft material into a desired shape, or (d) some combination (hybrid) of these types of processes.
• The markets for digital fabrication and digital manufacturing are _________________.
