Note this is a tutorial for 3D printing in the Colab using the Ultimaker printers.

1. Design a structure in a CAD software (E.g., Fusion 360 or SOLIDWORKS)

2. Export the structure as a .stl file

3. Drop your .stl file in the website: https://duke.3dprinteros.com (It will ask you to log in using Duke credentials) (Here you can also use Ultimaker Cura to set up the files but dropping the file directly in the website is the quickest way. I used this way all the time and there is no problem)

4. In the layout option on the right: select ‘on bed’ and ‘center’

5. Adjust the position of the structure by moving the arrows on the object

6. Material – by default use PLA, sometimes ABS (You need to bring your own ABS material to print in the Colab)

7. Click ‘slice’ at the bottom

8. Change infill density to 10% (Normally). You can increase the percentage for more strength but normally you don’t need that. For prototyping, you can start with a low infill such as 5% to test the structure out. Using a low infill density will make it quicker to print out.

9. Change printer type to ‘S3’ (Top left) and profile to ‘perfect S3’

10. Click ‘slice & toolpath preview ‘

11. Choose any printer with a name starting with TEC (Meaning it is a printer in the Colab)
