A 3D printer consists of 3 primary system: 1: The postioning system. This is the part of the machine that moves the deposition system, what ever it may be, around. This system is decended from XY protters and NC machinery, technology that is over a half century old and fully matured shortly after the microprocessor became commercially available over 40 years ago. 2: The deposition system. This is the part of the machine that deposits the material being printed, whatever it may be. All deposition depend on the material having liquid properties, at least for some time. For thermoplastic printers the solid plastic is melted in the deposition system and applied through a nozzle. For metal printers, the solid metal is in a micronized form such that it can be forced through a nozzle of some sort. The metal powder may or may not have a carrier material added to make the process easier. There is no way to "print" a material other than to squirt it in very small quantities (assuming one desires some sort of accuracy) out of a small oriface of some sort. The accuracy of the final printed product is directly related to how small an amount of material can be deposited at one time. 3: The hardening system. This is the part of the machine that hardens the the printed material. For a thermoplastic machine this may consist of nothing more than allowing air flow around the printed such that a given print pass can cool before the next print pass is applied. For a metal machine, there are several hardening methods, such as laser and electron beam sintering. -- Jim Pennino
