** '''Build Area:''' 400x400x400 mm (Roughly 15.75x15.75x15.75 inches)
** Has a heated bed (heats slowly, max 75 C, can be raised by insulated bed or building enclosure)
** Can work PLA

* [[tools:3D_Printing/Printrbot Simple|Printrbot Simple Makers Kit]]
** '''Build Area:''' Roughly 4x4x4 inches
** Can work PLA and ABS (has heated bed)
** '''Workflow:''' Connected to computer with Cura 2.4 series slicer.
** Portable; can run on battery power
*** Requires at least 12V @ 4A for running without heated bed
*** Running the heated bed on battery power has '''not''' been tested and is not allowed at present.
** '''Currently non-functional''' -- Power supply is dangerously unshielded.
* Solidoodle 3
** '''Build Area:''' Roughly 8x8x8 inches
** Has a heated bed
** Fully enclosed with acrylic sheeting
** '''Currently non-functional''' -- Has issues with Y-axis traversal, thermistor issues
* Mbot Cube (revision 1)
** '''Build Area:''' Roughly 8x8x8 inches
** No heated bed (though one can be added)
** Dual extruders (though they need alignment)
** Workflow
*** Uses Proprietary MPrint software to communicate with printer via USB
*** Can also print from an .x3g file read from the on-board SD card reader (2 GB maximum capacity); .x3g files can be made in ReplicatorG with appropriate configuration.
** '''Currently non-functional''' -- Bed alignment system is damaged; new print bed needed

* Anycubic Photon

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

== Usage and Workflow ==
The 3D printer is controlled via the desktop computer set up next to it. The basic workflow is this:

# Take a 3D model and convert it to an STL file.
# The STL file then must be converted to GCode.
# The GCode is sent to the printer for printing.

=== 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).

* [http://openscad.org/ OpenSCAD] is the more mature of the two programs. It uses a scripting language to define a model using CSG.
* [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://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.

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 ===
We recommend the use of PrusaSlicer (Slic3r) for the Creality CR-10. A settings file optimized for this printer is [https://gist.github.com/MaxBareiss/9f97218f1111aa1ae0247e9d0fbc3083 here]. The most important setting for this printer is to set the maximum acceleration limit to 500 mm/s&sup2;.

== 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).
