1.5cm/s isn’t that bad if you just do the outlines of the traces, same as how people mill PCBs.
Diptrace has an option where you can export the outline, I know people have written routines for Eagle etc.
As an aside, cutting speeds on typical hobbyist lasers (<50W) tend to be under 1cm/s. This took an hour to cut (3mm acrylic mirror, around 50x30cm):

Lasers are awesome.

I don't know. 1.5cm per second is pretty slow.

Are those solutions color sensitive or only thermal sensitive?
Why not 1W laser with reduced speed 10 times (from the recommended 15cm/sec) for the LMM14 spray?
