: For text on the top or bottom of a print that feels "solid" and smooth, set the text depth to be extremely thin (e.g., 0.1mm or one layer height) and ensure "top/bottom shells" are configured to fill the gap.

Are you using a printer (e.g., Bambu Lab AMS) or a single-nozzle printer? inroommp4

: In slicers like Bambu Studio or PrusaSlicer, you can add a text shape as a "Modifier". Set the wall count or infill of that specific text volume to 100% (solid) while the rest of the object uses standard infill. : For text on the top or bottom

: Create text as a solid volume (e.g., 0.1mm thick) and subtract it from the main model. This leaves a tiny void that the slicer treats as a surface, causing it to generate solid top/bottom layers around the void. Set the wall count or infill of that

: If using a multi-color printer (like a Bambu Lab with AMS), text can be modeled as a separate solid body within the main object and assigned a different "material" to print it as a solid, contrasting color. 💻 Implementation in Software Bambu Studio
