Measured, practical answers about engraving text and logos into 3D-printed parts - depth, minimum text size, file formats and batch serial numbers.
How deep should an engraving be on a 3D print?
Engrave 1.2 mm deep: 10 layers at 0.12 mm. Why layer count beats millimetres, the 0.6-2.0 mm range, the depth+0.8 mm wall rule and two-colour swaps.
Minimum text size for 3D printing: stroke width, not font size
The limit is 0.8 mm stroke width on a 0.4 mm nozzle, not cap height. Measured on real parts: 4.4 mm upright vs 8.3 mm rotated on one winder face.
3MF vs STL for personalised 3D prints
3MF keeps the print profile, plate layout, filament assignment and painted supports; STL keeps only triangles. Measured file sizes and when each format wins.
How to add a logo to an STL file without CAD
Add a logo to an STL or 3MF without CAD: which images trace cleanly, the 0.8 mm stroke rule, choosing a 1.2 mm depth, and checking the preview.
Serial numbers and batch personalisation for 3D printed parts
How to engrave PREFIX-0000 serial numbers into STL and 3MF parts, generate consecutive runs as one zip, and print a numbered batch. Measured at 4.1 mm cap height.
Try it on your own model. Upload an STL or 3MF, add a logo, a name or a serial number, and download a print-ready file.
