Now available for as little as $500, 3D printers can turn almost any CAD creation into a physical object. Sophisticated desktop units such as this MakerBot Replicator 2X ($2800) use dual extruders to print in two colors of plastic.

CNC Routing/Milling
These two machines are similar in concept, but they operate differently. Routers direct a rotating bit to shape wood and plastic, while mills usually move the material (mills are good at cutting metal). Both are the inverse of a 3D printer, subtracting material instead of adding it.
Pressing & Stamping
A standby of large-scale industrial manufacturing, machine presses force the manufacturing material against a premade form. Stamping machines cut out shapes much as a cookie cutter does. Both kinds of machine can produce parts much faster than printers and milling machines, but they are not as flexible.
7 Easy Steps for Launching a Startup
Hydro/Vacuum Forming
Vacuum forming is great for making plastic parts, such as electronics casings and packaging, which are heated, then vacuum sealed to a mold, then cooled. Hydroforming, which uses liquid pressure instead of a vacuum, is better for metals and other heavy materials.
Injection Molding
Rather than pressing material against a mold, an injection molder? forces material into one. These high-volume machines make parts out of glass, metal, or plastic.
Square Payments
Online retailing may be frictionless, but sometimes you?re out in the physical world. Technologies such as Square turn a smartphone into a credit-card reader.
