¶ 3D Printing Tutorial
¶ What is 3D printing?
Known as additive manufacturing (sticking material together) it is a process of making 3D objects.
Step 1 - Create or obtain a 3D object
Step 2 - Slice the model
Step 3 - Prepare the printer
Step 4 - Print the model
Step 5 - Clean up
¶ Step 1 - Create or obtain a 3D object
¶ Where can I get pre-made models?
You can download 3D models that people have already made. They usually come as .STL, .OBJ or .3MF
Try these websites
Thingiverse.com
Printables.com
3DCults.com
¶ How to make a 3D model
A good simple web based 3D model system is ThinkerCAD.com. This is as simple as dragging blocks onto a canvas, resizing them and adding more blocks.
One of our favourite pieces of free software for 3D design is Autodesk Fusion 360. But bear in mind this is a very powerful and quite complex beast so be prepared for a learning curve.
Once you have designed your model, it needs to be saved as a .STL, .OBJ or .3MF

Uses OctoPrint to manage 3D prints over the network
access the printer via http://10.0.3.142 when connected to the Hackspace WiFi.
The Username and password can be found on the front of the printer.
ToDo List:
- better clips for the door
- touchUI setup for the touchscreen
- filament storage (dry cabinet)
- order filament
- finish writing up this page with a how to guide
- fixed webcam setup
Auto bed levelling
add the following Gcode to the start of your file
G28 ; Home all axes
M140 S{material_bed_temperature_layer_0} ; set the heated bed temperature
M190 S{material_bed_temperature_layer_0} ; Wait for heated bed to reach temperature
M104 S160 ; warm up the extruder
G29 ; Auto bed-level
G92 E0 ; reset the extruder
If you are using Cura, go to Settings, Printer, Manage Printers. click on the FDM printer and then Machine Settings. It should look like this:
¶ Filament Dryer
The filament dryer box has a website to see the temperature and humidity and can be accessed via http://10.0.3.78
ToDo List:
- standalone unit
- power supply for heated bed and controller
- graphs for webpage
