Thank you! I'm checking it out now. This shop definitely seems to be in line with what I'm looking for.

I'm not sure if this is a common issue for the amount of hours most people log on their laser diodes for other purposes, but these diodes do not have an unlimited life expectancy. It seems to be pretty common for the laser module to be the first component that fails on these printers, if the...

I don't think I would describe the stock laser as sub optimal; I'm really not qualified to make that assessment even if it is. The biggest problem is that even if it's the best laser for the job, you can't buy a replacement and if you have a dead laser module it doesn't matter how optimal it...

That one is more interesting. I wonder what the spot size is though. Is says focusable <0.3mm. I don't know if that is saying you can focus as close as 0.3mm or that the spot size is 0.3mm. On the topic of power, I should clarify that the printer controls the amount of power going to the laser...

That one has the opposite problem. 10mW would not be nearly enough (I had to remove the link because I don't have a high enough post count) My thinking is that I will need a 120-150mW single mode 405nm diode and a lens. I'm completely unsure of what to use for a lens though. I'm guessing most...

Great questions. Dose is what we are interested in when curing resin. I think of dose as energy over time, which is what you're describing. The galvos in this printer are happiest at about 800mm/s in X/Y maximum feedrate. In other words, you can't achieve the correct dose if your laser power is...

Interesting. Why the need for such high power? The original laser is 120mW, I was thinking it could be more in that range. I also don't understand what you mean by "albeit slowly." I'm a noob, sorry!

The planned application is in a resin 3D printer (Formlabs Form1+). It must be 405nm because that is the wavelength that the resin cures at, so that is a hard requirement for sure.

I'm doing some experimentation with using different laser modules in the Formlabs Form1+ 3D printer and I'm curious about setting up a custom/DIY laser for it. I have done some searching on the forum, but I don't really know where to begin. I'm hoping someone can point me in the right direction...
