WP34s 20b Repurposed

[robert rozee]

can one "micro 3D print" onto an existing plastic surface? how about refinishing keytops back to blank with paint (applied through a mask), laser etching recessed writing, then micro 3D printing to fill in the recesses? this should produce a finish that is very similar to double-injection moulded keys.

the process would be impractical as a one-off, but possibly economic if someone were game to set up everything and do perhaps 100 calculators as a small production run.

btw, i'm advocating this just for the writing on the keytops. the writing on the escutcheon - which is subject to far less touching - is still (i believe) better handled with an adhesive label of some sort.

cheers,
rob :-)
