The Maker Select v2, Prusa i3, and Prusa i3 MK2 are open source 3D printers which are capable of printing with the following materials, acrylonitrile butadiene styrene (ABS), polylactic acid (PLA), high impact polystyrene (HIPS), polypropylene and nylon.

  • This procedure works for all three printers, the Maker Select v2, the Prusa i3 and the Prusa i3 MK2.
  • You can use various applications to prepare your product for these printers. Our default application is Simplify 3D (instructions below).


Specifications

Maximum Design Size: 42 x 42 x 38 cm (16.5 x 16.5 x 15 inches)

Layer Thickness: 70 W (printing PLA) or 100 W (printing ABS)

Creating a .gcode File

In order to print using these 3D printers, you will need to save your project (.stl or .obj) as a .gcode file. To do this, you will need both a (Micro) SD card and a (Micro) SD to USB adapter. The adapters are located near the Prusa i3 MK2 3D printer in a glass cup.

  1. Place the (Micro) SD into the SD to USB adapter and plug it into any of the available computers with Simplify 3D.
  2. Open the file to be sliced in Simplify 3D. This can be done by right clicking on the file and selecting "Open with Simplify 3D" or by importing your file through the Simplify 3D application: File>>Import Models (Crtl+I).
  3. Once the file is in Simplify 3D, there are two main settings to be adjusted, the process settings and the object settings.

Editing the Process Settings

These are the printer's settings. Select "Edit Process Setting" located near the bottom left corner to start.

  1. Begin by making sure the correct printer is selected (Select Profile):
    1. Maker Select v2 (Use Prusa i3 settings)
    2. Prusa i3
    3. Prusa i3 MK2
  2. Check to see if PLA is listed as the "Auto-Configure for Material"
  3. Check to see that Right Extruder only is listed as the "Auto-Configure Extruders"
  4. Run through all the tabs and ensure that the proper settings have been updated:
    1. Extruder (This should be left alone)
    2. Layer (This should be left alone)
    3. Additions (Edit as desired)
    4. Infill (Typically 20%)
    5. Support (Enable if there are any overhangs in the print)
    6. Temperature (Extruder: 205-210c Bed: 60c)
    7. Cooling (Prusa MK2 set Fan Speed to 30 near Layer 2)
    8. Advanced (Check to make sure "Start printing at height" and "Stop printing at height" are not selected)
     *The renaming tabs should be fine left alone.
     *Hover over each category in Simplify 3D, with the mouse cursor, to learn more about each individual setting. 
    
  5. Select "ok"

    Preparing to Print

    To adjust the print settings, double click on the Process Settings on the lower left. If there is not currently a Process listed, click "Add". On the drop down menu for "Select Profile", select the printer you will be using: Prusa I3 MK2. The ideal print settings will vary depending on the material you're using and the project you're creating. For most projects, the default settings for quality and material should be acceptable.

    • The default printing material is PLA
    • The default printing temperature and the build plate temperature settings are 210 and 70 respectively
    • Make sure your object is printing somewhere between 20-40% infill density (if you wish to increase it, please consult a staff member first)
    • By double-clicking on the object, you are able to change the position, size, and rotation of the object. Once you are finished click done.
    • If your object has any over hangs or material that is not touching the plate, check off the "Enable Support" box
    • Next, to ensure that your project will fit on the bed, double-click on the object and select the 'Center and Arrange Button'
    • Once satisfied with the project's orientation, quality and media settings, you are not ready to export your file.
    • Click "Prepare to Print!" on the bottom left
    • Click "Save Toolpaths to Disk" and select the correct SD card

    Printing Using the Prusa i3 MK2

    1. Once your file is saved to a Micro SD removable drive, you can now properly eject the removable drive and bring the drive to the Prusa MK2 printer.
    2. Toggle the switch to "On" in the back of the Prusa operations box located to the left of the printer.
    3. Remove the Micro SD from the Micro SD to SD adapter, place it in the slot on the right hand side of the operations box. The slot is labled "SD."
    4. Press the dial on the front of the operations box to open the Prusa menu
    5. Using the dial, navigate down to "SD Card" and tap to select.

    1. Follow the following menu prompts:
      1. Mount SD Card
      2. Print File
    2. This will show you a list of the .gcode files located on your Micro SD. Select the file you wish to print.
    3. Press the dial to print
