### 3. Slicing in Chitubox ### 3. Slicing in Chitubox
This is where you set the exposure time. The Chitubox slicer (without hacking) requires at least one bottom and one normal layer to be defined. So, the idea is to split the thickness of the model into two or more layers and define the exposure time for each layer. This is where you set the exposure time.
