3D Printer Tutorial

Materials Required:

Software Required:

Hardware Setup:

Calibrate the Heating pad via moving the nozzle to each end of the bed and making sure a piece of paper can fit under it. Use the Gears on the bottom to adjust accordingly.
Apply glue to the heating bed surface where the object will be printed

Software Setup:

Download Utimaker Cura via https://ultimaker.com/en/products/ultimaker-cura-software
Setup a printer profile by going to and selecting “Add Printer”
Click on “other” and find the Creality Ender 3
Open a file you wish to print (.stl, .obj)
Go to Custom Settings in Cura 3D
Leave infill % at 100 to insure that it is strong and won’t fall apart. Validate your settings as provided in the below screenshots.
Click File → Export and choose the file types as .gcode as the Creality Ender 3 only accepts .gcode file types (please note that the Ender 3 does not take ANYTHING except .gcode)
Export it to the USB/Micro-SD so that you can use the SD card in the Printer (meaning when exporting as .gcode drag it into the USB).
Use the USB with the .gcode file to print it on the Ender 3. Follow the on-screen prompt and use the dial to navigate the menus.

Common Problems:

If you find troubles in terms of the hardware, like the nozzle not printing the filament properly, consult this guide: https://all3dp.com/1/common-3d-printing-problems-troubleshooting-3d-printer-issues/

The PLA filament looks stringy
Solution: Set the temperature between 185c and 205c preferably lower in this case.https://rigid.ink/blogs/news/3d-printing-basics-how-to-get-the-best-results-with-pla-filament
Filament is coming apart
Solution: Recalibrate the heating bed and glue the surface of the heating bed where the object would normally be printed.
