PrusaSlicer can recognize “things that look like logos” and process them with two different materials, so I tried it out with some plant signs:
They came out surprisingly well, particularly for characters with two adjacent filament threads:
Smaller characters with single threads show more stringing, a characteristic of PETG, but it brushes off easily enough:
While the existing text isn’t nearly as informative as real plant tags, they’re surely more durable and a chunkier font would improve both printability and readability.
I suggested Mary hand them out to any of her gardening cronies in need of a chuckle …

A friend has been “engraving” white panel legends on black PETG with a 1 µm fiber laser. Apparently the near-IR energy bleaches whatever they use for black dye without melting the plastic, producing a flush white legend.
So many projects …
