I’m quite new to resin printing and I was wondering if one was able to post-cure their prints with he printer’s built in “cleaning” function. I mean, it’s a pretty powerful UV light, right there. Does this damage the LCD more than usual? I was thinking of just “roasting” prints to cure them. If anyone tried it before, do share.
The main issue I see with that is uneven curing. Since the UV is only on the bottom, it would only cure where the UV can hit it. I suppose it might be possible if you manually turned the print to cure every angle, but I imagine this still wouldn’t cure evenly.
Yeah I was about to post the same.
I actually modified my old printer (sparkmaker) to be my curing box. To solve the turning issue I put the LED panel upright by strapping it to the Z linear rail, chopped short the Z lead-screw and attached a lazy Suzan to that screw.
The easiest turn table is a microwave oven’s motor for a low speed, mains powered device. You can likely find one on the curb for free depending on where you live.
I haven’t tried with resin, but when I’m using photoresist to etch my own circuit boards, I use the sun because It is effortlessly fast. However I also have a fingernail polish curing stand. These are a cheap option for a decent UV curing lamp. If you use the Sun be sure it is a completely clear day at around solar noon if consistency matters. Even light clouds can cause weird refractive inconsistencies in my experience.
The screens generally have a short life in resin printers. I wouldn’t use it for this.
Just feel like this needs to be said, if you have any intention of opening up a microwave oven, know that just touching certain parts can kill you even if it’s been off for a while
Notwithstanding part lifetimes, I don’t think you’ll get even enough – or even enough in general – UV exposure to produce satisfactory results. Also, while you’re doing this you won’t be able to use your printer for anything else.
I think buying or rigging a curing box will be significantly less irritating. And probably cheaper in the long run, too.
Haven’t tried to use the printer for curing. I built my own curing box using a decommissioned microwave, some spare wood and mirrors, and a rather powerful UV source.
I guess you could build yourself a mirror box to hold the object and place it on the printer instead of using a separate UV source.
The printer should be able to handle the generated heat, so I don’t think you’ll see increased wear.
If you can truly afford resin printing and all the waste and resources and safety equipment required, you can afford a wash and cure station. Use the right tool for the job.
also you risk some droplets of resin, or even the print itself, sticking to the LCD and damaging it. Than you’ll spend money buying another LCD on top of the station.

That was the first thing I thought of. Not worth the risk to such a sensitive piece of equipment.
Tbf it’s not worth the risk of damaging your LCD and the pain of having to change it
