== Current Filament Available ==
* PLA filament (transparent blue) -- ~1kg spool
* ABS filament (green) -- ~1kg spool


== Usage and Workflow ==
== Usage and Workflow ==
The 3D printer is controlled via the desktop computer set up next to it. The basic workflow is this:
The general process for 3D printing is outlined below. Please see the individual printer pages for full details.


# Take a 3D model and convert it to an STL file.
# Convert 3D model to STL or download an STL file from online.
# The STL file then must be converted to GCode.
#* https://www.printables.com/
# The GCode is sent to the printer for printing.
#* https://www.thingiverse.com/
#* etc
# "Slice" the STL file to generate GCode (or resin printer file).
# Prepare the printer
#* Load filament
#* Clean/level the bed
#* Change nozzles if needed
# Send the GCode to the printer.
# Monitor the printer until the print is completed.


=== 3D Modeling/STL creation ===
=== 3D Modeling/STL creation ===


We have three CAD programs installed for creating 3D models. Two rely on the principle of [[wp>Constructive solid geometry|Constructive Solid Geometry]] (CSG).
We currently recommend [https://www.solidworks.com/solution/3dexperience-solidworks-makers SOLIDWORKS for Makers] or [https://www.alibre.com/atom3d/ Alibre Atom3D] which are both available on the laser-room computer. Autodesk [https://www.autodesk.com/products/fusion-360/personal Fusion 360] offers a free license for hobbyist use. [https://www.onshape.com/ OnShape] offers a free online CAD editor (note: all free OnShape models are publicly shared).


* [http://openscad.org/ OpenSCAD] is the more mature of the two programs. It uses a scripting language to define a model using CSG.
Other options which are FOSS include:
* [http://www.mattkeeter.com/projects/antimony/3/ Antimony] is a new program, released in Spring 2015 as a visual approach to CSG. While it is easier to use, its STL export is considerably cruder (it uses a naive algorithm for creating models).
* [http://openscad.org/ OpenSCAD] uses a text-based scripting language to define a model, making it distinct from other CAD software. It is great for making parametric parts, where a user can easily modify critical dimensions.
* [http://www.mattkeeter.com/projects/antimony/3/ Antimony] is another procedural modeling software, which uses an interconnected graph of nodes to define geometry (rather than plain text). It is no longer receiving updates.
* [http://solvespace.com/ SolveSpace] is a constraint-based, parametric CAD program. It has the advantage of having a more traditional CAD interface, but there is a bit of a learning curve; going through the tutorials on the program's website is highly recommended.

* [https://www.freecad.org/ FreeCAD] is a constraint-based, parametric CAD program. Its interface is usually considered more difficult, but recent updates have improved the experience. It is a very powerful software with many built-in tools.
Alternatively, you can download an STL file from an online 3D printing repository like [[https://www.youmagine.com/|YouMagine]] or [https://www.thingiverse.com/ Thingiverse].
 
=== GCode Production ===
STL is converted to GCode using a ''slicer program'' which produces GCode of slices of the modeling file for the 3D printer to print. The best slicer for the Printrbot is [http://wiki.ultimaker.com/Cura Cura], which is preinstalled on the computer.
 
The Solidoodle and Mbot have their own workflows. Solidoodle uses Pronterface to send Gcode, though work is ongoing to find replacements. Mbot's software toolchain is a bit more complicated; supposedly, it uses RepetierHost, but initial tests were unsuccessful. The Mbot has an onboard control panel with an SD card reader, but uses a nonstandard format for printer instructions (not G-code). Investigations are ongoing.

== Webcam Access ==
There are three options to access the webcam to view 3D prints in progress.
* Static View: [http://216.252.200.71:65413/cgi-bin/CGIStream.fcgi?cmd=snapPicture2&usr=Snap&pwd=123snap! Click Here] (This does not work on Hacksburg WiFi, refresh the page for an updated image.
* Basic Stream:
*# Open VLC and navigate to Tools>Preferences.
*# In the bottom left corner of the Preferences window under "Show Settings" click the "All" option.
*# In the search box, type "Image Demuxer" and select the "Image" option.
*# Change the "Duration in Seconds" option to 1.00 seconds and click save.
*# Turn on looping.
*# Select Media>"Open a Network Stream" and type <nowiki>http://216.252.200.71:65413//cgi-bin/CGIStream.fcgi?cmd=snapPicture2&amp;usr=Snap&amp;pwd=123snap!</nowiki> into the Network URL box.
*# Click Play and the video should begin playing at ~1 FPS
*# '''Note:''' This method is a workaround if you do not wish to install the IPCWebComponents.exe required for full camera control. That method provides better video quality and the option to pan/tilt/zoom.
* Full Control: [http://216.252.200.71:65413 Click Here] Visit from Internet Explorer initially to download and install IPCWebComponents.exe. The interface can then be accessed from other browsers (does not appear to work in Firefox).

== Planned Printers ==
* Prusa i3 derivative
** Planning discussions started in early January 2015, but stalled.
** '''Current components:''' RAMPS board, Arduino, heated bed, thermistor, user interface board, one pulley with CL2 toothed belt
** '''Missing components:''' Just about everything else
