3D printers are a new technology that enables users to print a solid object using a variety of materials.  These are used in private, educational, manufacturing, medical, and other venues.  To use this type of printer a user creates a 3D model on a computer, then sends the job to the printer.  The printer then constructs the object on a mat, by moving the nozzle (or print head) on a dual-axis assembly and releasing small amounts of the material where it is needed. In general, these printers are very slow in comparison to 2D printers, but the technology is still evolving and improving significantly.<br />

====Support materials====
  −
These are materials which are needed during printing to support parts of the product, during construction, but must be removed when the job is complete.  These are printed to fill the space, then dissolved later, leaving only the intended product, with the intended voids.

Plotter printers are used to produce images, usually on large sheets of paper. As plotter technology evolves, theses printers become faster, but they still generally take some time to complete their tasks.  Since they are slower than most other modern printers, they are generally not used for regular-sized printing tasks.<ref>https://www.techwalla.com/articles/how-does-a-plotter-work</ref>

==Varieties==

===Flatbed===
 
Flatbed plotters have a tray, in which the paper (or other medium) is held stationary.  The plotter uses a pair of pens (hollow fiber rods, sharpened at the end) which move vertically and horizontally across the paper, plotting out the final image.  These printers are sizable, since they must be larger than their product.<ref name="techwalla.com">https://www.techwalla.com/articles/plotters-their-types</ref>

===Drum===
 
Drum plotters reduced the required size of this technology, which using the same basic method.  Paper is attached to a large drum using a pin feed attachment.  The plotter then runs pens vertically across the paper, and the paper itself is moved horizontally by rotating the drum when needed.<ref name="techwalla.com">https://www.techwalla.com/articles/plotters-their-types</ref>

====Electrostatic====
+
===Electrostatic===
 
An electrostatic plotter charges portions of the paper negatively.  Older plotters did this by running a line of electrodes across the paper, although newer printers generally use laser, much like any other laser printer.  The toner is charged positively, so that is is attracted to the desired areas, where it is then fused.<ref>http://www.pcmag.com/encyclopedia/term/42512/electrostatic-plotter</ref><ref>http://link.springer.com/referenceworkentry/10.1007/1-4020-0613-6_6038</ref><ref>http://www.globalspec.com/learnmore/industrial_computers_boards/computer_peripherals/computer_printers_plotters</ref>

===Inkjet===
 
One of the newest and probably the most popular kinds of plotter uses the inkjet printing method.  Liquid ink is delivered to the paper as droplets using the inkjet method

====Cutting====

===Cutting===
 
A cutting plotter does not actually use ink to print forms, and by some definitions, may not even be considered a printer. These devices use a blade rather than a pen, and cut out pieces of material.  These pieces are usually used as graphics for signs and other media.<ref name="smallbusiness.chron.com">http://smallbusiness.chron.com/plotter-printer-work-33056.html</ref>

===Materials===
 
Depending on the purpose and design of the 3D printer, it can use a wide variety of materials.  The material is sold as filament sized at either 1.75mm or 3mm, which is fed into the nozzle, melted, and released as needed. These include:
