Parts of a 3D printer
There are many models of 3D printer, but all of the printers that use filament have the same basic parts. Two fundamental categories of printer are the cartesian and the non-cartesian. Here's a cartesian printer. It's now moving in the x-axis, now the y, and finally in the vertical z-dimension. Be sure you remember that z is the vertical direction and that z = 0 at the surface of the platform. The most common non-cartesian family of printers are called deltas or delta bots. They still use the same conventions of calling the axes parallel to the stationary platform x and y, with z being vertical. For non-cartesian printers, these do not correspond directly to individual motors as they do for most cartesian machines. 3D printers have four or more motors. Typically, three motors are used to move the printhead and/or platform in three dimensions. In some cases, the printhead may move in all three dimensions while the platform remains stationary. More commonly, though, the platform may…
