To slice a 3D model with custom wall thickness, import the model into slicing software (e.g., Cura, PrusaSlicer) and adjust the “Wall Thickness” or “Perimeter Count” settings. This defines how many solid layers form the model’s outer shell—thicker walls add strength, thinner ones save material. Use the software’s layer preview to check wall evenness. For beginners, start with a standard 1.2mm thickness for most PLA projects.
