Honestly I’ve tried all sorts of lasers and been disappointed with all of them.
From a 5mW pointer like this:
To 200mW “professional” model like so:
And a 5W (1800mW/cm²) dental tool:
None of them cured the resin fast enough for me. All were 405nm products.
Then last year I spoke with one of the dental guys at the Formlabs User Summit and he let me try out one of these to glue together a set of dentures:
That’s the guy you need, at least if you’re “impatient” like me. It does 3W/cm². I bought one as soon as I got back. It ain’t cheap.

Suggest you also pick up a pair of safety glasses. (He said you didn’t need them, but I’d say they’re prudent).
Edit: Just realized that last photo shows the 365nm version. Be sure to buy the 405nm one (order # 2182207).
