1. Design preparation:

   • Make sure your 3D model is ready for printing.
   • Use appropriate design software (e.g. 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-made 3D files for printing can be found at, for example:
     Thingiverse
     printables.com
     
     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 software
   If necessary: ​​Ask your teacher for instructions on where it can be found on your school computer.

1. • 2.1/ ​​Import your 3D model into the software, Elegoo Cura 2.1-Alt1/ -Open via menu -Select where you 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 build 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 NOTE: Make sure no models are in the air! They need to have good contact with the build platform.
     2.5/ Select print settings in the right menu 2.5.1/ Select Layer height: A layer height of 0.2 is enough 2.5.2/ Choose material infill: 15-25% (If you want a strong part, you can increase to 30-60% infill) 3/ Click in the "Support" box
     2.6/ Prepare 3D model for printing by pressing "Slice"
     2.7/ Save the created .gcode file to USB flash drive by clicking "Save to file" - Select your USB memory, in the following example the USB memory is "USB Drive (D:)" -Select save

2. Section Ready!

3. 3D Printer Preparation:

   4.1/ Turn on the 3D printer via the button at the back 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 the folder where you have saved your prepared 3D model's .Gcode file. 4.5/ Press the name you saved the gcode file to, e.g. EN4PRO_The Buddha.gcode 4.6 Press the "Confirm" button, your 3D printing will now start.
   5. Check the printer when starting 3D printing 5.1/ Be careful not to let the 3D printer nozzle scratch and damage the build platform!!	If that happens, you will A/ Not seeing any plastic coming onto the construction platform B/ You will then hear a metallic scraping sound from the 3D printer, then turn off the printer/Cancel printing IMMEDIATELY to avoid damage.

4. After printing:

   • Once the print 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 bend it gently to easily remove the model
   • Carefully remove the print from the build surface with a plastic spatula or similar tool, being careful not to damage the build surface or the model.
   • If necessary, remove any support structures or base plates from the printed object.
   • Clean any excess filament strands or gaps on the print and from the printer.

For Teachers - Coming Soon:

1. • Teacher/Educator Maintenance

1. • Check and, if necessary, clean the print surface and print head regularly to prevent the 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, isopropyl alcohol or a similar cleaning agent.
   • Check and calibrate the nozzle height to the build platform regularly to ensure optimal performance. You can do this via the 3D printer display ---> settings (gear) ---> leveling
   • Store the filament properly in a dry and dust-free environment to prevent moisture absorption and degradation of the filament.
