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.
