Text that prints well

Size

• Letters smaller than about 5 mm high get hard to read with a 0.4 mm nozzle.
• Thin fonts lose detail. Bold fonts print cleaner, especially when small.
• Raised text of 0.8–1.2 mm is enough. Higher letters are more likely to break off.

Raised or engraved

Raised text is the easiest to print and to swap color on. Engraved text is more durable, because nothing sticks out. It looks best when the engraving is at least 0.6 mm deep.

Slicer tips

• Use 0.12–0.16 mm layers for small text.
• Turn on "ironing" for the top surface if your slicer has it: the flat area around the letters gets very smooth.
• Slow down the outer walls for sharper letters.

Long names

Many text tools scale the letters to fit automatically, so a long name gets smaller letters. If the text gets too small, make the part longer or use two lines where the tool offers it.
