It looks like it may be possible to use UV leds instead. I did some
Googling and found some info on a particular resin, which mentions
365nm as a quick curing wavelength:

Nichia makes UV leds with a peak of 365nm:

And this site describes actual industrial use:

It may require multiple leds and a lens to get a high enough
intensity, but it should work.
