The Prusa i3 MK3 is a 3D printer that includes a removable heatbed, filament sensor, and other unique features in order to rapidly prototype projects. The Prusa i3 MK3 comes in two different variants, single filament, and multi filament.

== Terminology ==

=== Nozzle/Extruder ===
The nozzle (or extruder) is the part of a 3D printer which deposits the molten plastic filament onto the 3D printer bed. The extruder can reach 200°-300°C, depending on the filament used, but typically stays around 215°C for regular prints.

=== Heatbed ===
The heatbed is a 9.83" x 8.3" x 8.3" plate where the filament will be "printed" on. The bed heats up to around 60°C. Heated beds typically prevent the plastic from warping by keeping it warm. Warping is a common issue that happens on 3D printers, where the plastic of the print cools at an uneven rate, leaving the print wavy and not the way you intentioned.

=== Feeder ===
The feeder is the part of the 3D printer that "feeds" the filament to the nozzle. Sometimes "feeder" and "extruder" are used synonomously, so it's important when you're teaching someone to differentiate whether or not you're talking about the ''nozzle'' extruder or the ''feeder'' extruder.

Feeders are typically composed of stepper motors, gears, and sometimes bolts and pulleys to guide the filament to the hotend.

=== Fan ===
There are usually two fans on the nozzle of a 3D printer, and they serve the purpose of cooling the plastic as soon as it comes out of the nozzle. If the plastic is super hot, we don't want it to move as soon as it is in place on the part we're making, otherwise our part will turn out warped or failed. The fans are put in place to strategically cool the plastic as soon as it comes out of the nozzle.

You are able to turn the fan speeds up and down in the slicer software (if that is a provided feature), but you can manually configure it on the printer as well.

=== Stepper Motor ===
There are two main places where you'll find stepper motors on a 3D printer. There's a motor for each axes, one for the x, y, and z. These motors receive instructions from the gcode to move the certain axes at certain points to create your print.

There is also a stepper motor in the extruder setup, pushing and pulling the filament whenever more or less is needed for the current print.

=== Infill ===

=== Filament ===
There are many different kinds of filament you can use on the 3D printer, ranging from PLA, ABS, TPU, and Nylon. The most common of these are PLA and ABS.

PLA stands for Polylactic Acid, it is the most common desktop 3D printing filament because it is odorless and very hard to warp on its own, therefore not always a need for a heated bed.

ABS stands for Acrylonitrile Butadiene Styrene. It's one of the most commercial versions of plastic available (found in legos, packaging, and more)--it's durable, scratch resistant, and tough. Heated beds are a must with ABS filament because it is so temperature sensitive, so it warps very easily.

==== Sizing of Filament ====
There are two mainstream sizes of filament, 3.00mm and 1.75mm. The 3.00mm filament is typically used on higher end machines--printing stronger and more detailed models. Hobbyist printers lean more towards the 1.75mm filament, for marketing purposes as well as hardware purposes. The Prusa i3's use 1.75mm filament.

=== CAD Modeling and Thingiverse ===
There are two ways you can 3D print models. You can either design your own with a CAD (computer-aided design) software, or you can find something similar to what you want on websites like [https://www.thingiverse.com/ Thingiverse]. Thingiverse has all sorts of community-contributed designs, which you can download the .stl files for, slice, and print the models.

As for modeling your own projects, there are multiple softwares you can use such as SolidWorks, AutoCAD, Autodesk Inventor, FreeCAD, and many more.

=== Slicing ===
Each 3D printer uses a slicer software, a software where you can import the model file (usually an .stl file) onto a computerized build plate, resize, change up the nozzle and bed temperatures, adjust the infill and precision, and more. The slicer software takes into consideration all your configurations, then "slices" it into a .gcode file, a set of instructions for the x, y, and z dimensions. The 3D printer can read and tell the stepper motors what to do from the set of instructions within the gcode.

The slicer software used for the Prusa i3 MK3 is called PrusaControl.

Jconsenz18: /* 3 commandments */

The prototype lab contains a group of 3D printers and a laser cutter (more to come in the near future)!

The Aces of the Prototype Lab are: Ben Kraske (bkraske16@georgefox.edu) and Gabi Lorenzo (glorenzo16@georgefox.edu).

==General 3D Printing Knowledge==
3D printing is the process of joining material together to create a three-dimensional opject using computer control. It is a form of additive manufacturing. Objects are created using a 3D model. There are many different types of 3D printing, and the Prototype Lab utilizes two types which are FDM (fused deposit modeling) and SLA (stereolithography).

In the Prototype Lab, objects are most commonly printed from an STL file. This means if you create a part in Solidworks that you must save the file as a STL instead of a SLDPRT. Once the file is in STL form, it can then be processed by a slicer software. The slicer software converts the 3D model into thin layers and produces a G-code file. G-codes communicate with the chosen 3D printer, giving it directions on how to print the object.

Different 3D printers will run with different slicer programs. Typically a program will allow you to edit various parts of the process. One common consideration will be that of the layer thickness. This is the resolution at which the printer will print at. Each printer will have its own range of resolution. The thinner the layer thickness (higher resolution), the more detail you will get, but the print will be created more slowly. The thicker the layers (lower resolution), the less detail you will receive, but the object will be printed more quickly. Another consideration is support. For objects with overhangs, holes, etc., support will be needed. This will give the printer a surface to print on so that it can continue to build the print layer by layer. Each printer uses supports differently. Some printers have break away support while other have dissolvable support material.
