Print your file
Once you have sliced your design, you need to get the sliced file from your computer to the 3D printer. The Prusa printers have a USB stick. The Bambus have a MicroSD card, but we usually use Wifi to print to the Bambus.
In your slicing program, once you have sliced your file, you will have the option to export the .gcode. The .gcode file is what your 3D printer needs in order to make a print. It contains all the information telling the printer what to do for each layer. If using a Prusa, take the USB stick from the printer and insert it into your computer. Save the .gcode file onto that stick. Then insert the card back into the printer.
To print your file you need to make sure the filament is properly loaded. Make sure the nozzle is hot before loading or unloading filament! Make sure your printer bed is clean and positioned properly. To ensure good bed adhesion, you can use a washable glue stick to add a thin layer of glue.
Use your printer’s menu to find the project that you have saved. Then click Print. You do not need to watch the printer print the entire project (although it can be mesmerizing), but you should watch the first layer or two to make sure everything starts like it should. If a print is going to mess up, it usually does it in the first layer, and by catching a messed up print early, you can save yourself lots of time and filament! If anything does mess up, just stop the print, clean off the bed, make any necessary adjustments and restart the print.
Once your project is done printing, remove the magnetic plate from the printer, and carefully take your print off the plate. If you had to use support material, carefully remove it. You now have a completed 3D printing project!
