OverviewThe Prusa i3 MK3 is very easy to use and very reliable if treated properly. Filament changes are simple, and the PEI coated bed is secured magnetically to the printer, allowing it to easily be lifted off (once the part is cooled!) and flexed to remove difficult parts - no scraping required (or allowed!). AuthorizationIf you are trained for the Makerbot or Robo3d R1+, read all these instructions and contact 3dprinting@makeitlabs.com to confirm you have read them you may use this printer. If you would prefer a hands-on intro to the machine that can also be arranged. How to use the printerThe steps you must follow when using this printer:
Slicing the fileYou may use either Prusa Slicer or Cura 3.6 to prepare files. Both Prusa Slicer and Ultimaker Cura are set up on the 3d Printing Desktop with the recommended profiles. DO NOT overwrite the default profiles - you can create one with a new name to save personal modifications for infill, layer thickness, support, etc. Note: If you want to install Cura 3.6 on your own machine and set up the Prusa-provided profiles, follow these instructions after Cura 3.6 is installed: You may adjust the following settings:
Do not adjust any Speed, Temperature, etc settings without approval. Moving the file to the printerSD Card MethodFrom Cura, save the file to a full-size SD card, at the root of the drive. Then insert that SD Card into the lefthand side of the Prusa's front panel, contacts facing you. Octoprint method(Detailed instructions coming) Connect to Octoprint for this printer, load the file Turn on PrinterThe power switch is located on the right hand side of th printer, at the base of the power supply.

Wait for Bed to coolDo not attempt to remove the print before the print bed temperature is 35 degrees or below. This can damage the printbed, and if so you will then be responsible for replacement cost. If you're in a hurry, fan the printbed with a magazine (or an actual fan) to speed up cooling. Do not apply water to the be to try and cool it down. Remove the partThe Prusa has a flexible, magnetic PEI steel bed. This means if the part cannot be pulled off easily with just your fingers once the bed has cooled, you can lift up the sheet, flex it slightly and your part(s) will pop off. To remove the sheet place your thumbs on the "fingerprint" symbols at the front of the printbed (about an inch from each front corner) and use your index finger to slowly and gently lift the thin metal print surface. The magnets are strong, do not be surprised. Clean the bedIf you printed with PLA, be sure to remove any skirt/brim and the wipe trail at the front of the bed. If you printed with PETG or anything else that required PVA glue, clean off the PVA with warm water and a paper towel Unload FilamentSee "Loading/Changing the Filament" Approved FilamentsApproved PLA: Prusa Filament (Prusament), Hatchbox, AIO Robotics, ColorFabb PLA Not approved PLA: ANYTHING ELSE. Specialty PLA (CF-reinforced, Metal-filled, Wood-filled, etc) as well as all other material types (PETG, ABS, Nylon, HIPS, etc) require special procedures and can damage the printer if used incorrectly.
