3D Printing Induction - swindonmakers/wiki GitHub Wiki

(Will add images later)

Mainly based on using the Prusa i3 MK2, the orange + black one

This is a 3D Printer

  • Output molten plastic via the hot end (200+ degrees C!)
  • Bed is also warm or hot (60 - 100 degrees C)
  • X, Y, Z movement don't obstruct or interfere
  • We use a web based software (Octoprint) to send files to two of the printers, and an SD card for the third one.

You will need

  • A model, as a .STL file - download or make using CAD software
  • Slicer software - Cura (by Ultimaker)
  • A computer (there's one in the space)
  • Much time (likely an hour at least)

Slicing

  • Choose the correct Printer in Cura - Prusa i3 Mk2 for the one we mostly use.
  • Open your .stl file.
  • Drag the on screen image around check for red coloured parts that aren't on the base - these will probably need supports. (see Support option in menu)
  • Note you can rotate the item to print it a different way up, which may need less support.
  • If your item has a small base area, or thin base walls, it will probably need a Brim
  • Hit the Slice button.
  • Preview the results, look through the layers to see if you were wrong about not needing supports.
  • Look at the (estimated!) time required, if it is too long, think about using a different Profile, or less Infill.
  • Save the .gcode file after final slicing.

Repeat above until satisfied with the result - this may also include starting a print, noting you were wrong about one of the settings, stopping it, and re-slicing.

Printing

  • Turn on the printer and its Raspberry pi (2 power switches!)
  • Check the printer bed is clear and clean of old prints.
  • Open the printer's Octoprint page in a browser.
  • Connect the printer using the button in Octoprint, if not connected.
  • Upload your .gcode file and wait for it to save and appear in the list.
  • Print your file.

Now wait and watch!
