If you are into 3D printing, you have definitely heard of G-code. It is a set of commands that control the printer's operation: where to move, how fast, how much material to extrude, what temperature to maintain, and so on.
How is G-code related to slicers?
When you upload a 3D model to slicer (for example, Cura, PrusaSlicer, Bambu Studio), it slices it into layers and creates step-by-step instructions for the printer. These instructions are what gets recorded in G-code.
For example, typical commands might look like this:
- G1 X50 Y20 E5 – move to coordinates (50,20) and extrude 5 mm of plastic
- M104 S200 – heat the nozzle to 200°C
- M140 S60 – heat the bed to 60°C
G-code can be viewed, edited manually, or even written from scratch if fine-tuning of the print is needed. But usually, the slicer does everything automatically.
You upload a 3D model, the slicer "slices" the model into G-code so the printer understands what to do.
