Initial checklist for preparing 3D printing with elegoo Neptune 4 3D printer
  1. Preparation of design:

    • Make sure your 3D model is ready for printing.
    • Use appropriate design software (eg Tinkercad, Fusion 360, SolidWorks) to create or download a 3D model.
    • Check the model for any errors, such as
      non-manifold geometry or intersecting surfaces.
    • Ready 3D files for printing can be found at, for example

      3D files need for elegoo cura slicer software to have file formats such as .stl .obj .3MF
  2. Prepare 3D file for printing with Elegoo Cura slicer program
    If necessary: ​​Ask your teacher for instructions on where to find it on your school computer.
      • 2.1/ ​​Import your 3D model into the software,
        Elego Cura
      • 2.1-Alt1/
        -Open via the menu
        -Choose where you have saved the file
        -Select open
      • 2.1- Alt2/ by dragging the 3D model from the computer into the elegoo slicer box.

      • 2.3/ Place the 3D model in the center of the construction platform
        2.3.1/ Select your 3D model
        2.3.2/ Drag the model around in each direction by clicking the left mouse button
      • 2.4/ Orientation
        Place the 3D model that has the largest flat surface against the build plate.
        - Click on 1 in the left menu
        -Click on number 2 in the left menu
        - Click on number 3 on the 3D model
      2.5/ Select print settings in the right menu
      2.5.1/ Select Layer height: A layer height of 0.2 goes a long way
      2.5.2/ Choose filling material: 15-25% (If you want a strong part, you can increase to 30-60% filling)
      3/ Click in the "Support" box
      2.6/ Prepare 3D model for printing by pressing "Slice"

      2.7/ Save the created .gcode file on a USB stick by clicking "Save to file"

      - Select your usb memory, in the following examples the usb memory is "USB Drive (D:)
      -Select save

  1. Section Done!

  2. 3D printer Preparation:

    4.1/ Turn on the 3D printer via the button at the back on the right side, Let the printer start up
    4.2/ Check that there is plastic thread (filament) left on the roll above the printer, otherwise ask a teacher for help (The printer will also tell you if the material is out, then ask the teacher for help)
    4.3/ On the 3D printer's touch display, press "Print"

    4.4/ Browse/select folder where you have saved your prepared 3D model's .Gcode file.

    4.5/ Press the name you have saved the gcode file to, eg EN4PRO_The Buddha.gcode

    4.6 Press the "Confirm" button, your 3D printing will now start.

    5. Check the printer when starting the 3D print

    5.1/ Be careful that the nozzle of the 3D printer does not scratch and damage the build platform!!

    If that happens, you will
    A/ Do not see any plastic coming onto the construction platform
    B/ You then hear a metallic scraping sound from the 3D printer,
    then turn off the printer/Cancel printing IMMEDIATELY to avoid damage.
  3. After printing:

    • After printing is complete, allow the print surface and model to cool before attempting to remove the print.
    • The build platform is magnetic so you can also lift it off and gently bend it to easily remove the model
    • Carefully remove the print from the print surface with a plastic spatula or similar tool, being careful not to damage the print surface or the model.
    • If necessary, remove any support structures or base plates from the printed object.
    • Clean up any excess filament strands or gaps on the print and from the printer.

For Teachers - Upcoming:

    • Maintenance of teacher/Educator
    • Clean the print surface and print head regularly to prevent build-up of debris or filament residue.
    • If the build platform is very dirty, clean the print surface to ensure proper adhesion. This can be done with lukewarm water and, if necessary, with isopropyl alcohol or similar cleaning agents.
    • Check and calibrate nozzle height to build platform regularly to ensure optimal performance. You do that via "leveling"
    • Store the filament properly in a dry and dust-free environment to prevent moisture absorption and degradation of the filament.
