Getting started with 3D printing
This is the basic process of 3D printing to help you get started. We can help you with any of the steps along the way.
1. Design or source your 3D model
Design your own
There are many different programmes that you can use for 3D modelling. Here are a few:
- Tinkercad – Free online program for 3D design. Best place to start for beginners.
- Blender – Free downloadable program for 3D design. Can do very advanced 3D models as well as animation.
- Fusion 360 – You can get a free hobbyist license for this. It’s good for mechanical style modelling.
Source an existing model
Makers are great at sharing! You can find lots of designs online, a few good sites are Thingiverse, Printables and Thangs. Remember to check the details for info about whether it needs supports. The comments can also be helpful to see how well it’s turned out for other people.
You can also find existing models and bring them into a 3D design programme to adjust them to what you want.
Once you have your 3D model, export or download it.
STL file
filename.stl
This is the most common file type but there are other ones that you can use too.
2. Slice the 3D model
Slicing turns your 3D model into a file that the 3D printer will be able to use to print it.
Slicer software
- Import your STL file.
- Prepare your design for printing: you can adjust quality settings, wall thickness, infill, supports etc.
Which slicing software you use will depend on which printer you are using. You normally download them and install them on your computer.
The slicer software will create:
g-code
filename.gcode
3. Print
Until you are trained and licensed to use the 3D printers at TAP lab you will need someone to do this part with you.
- Choose and load your filament (the plastic it prints with) on the printer.
- Send your g-code to the printer.
3D printing isn’t a fast process. Unless your design is small you will probably need to leave and pick it up later.
