I've bought recently this UV lamp to cure my SLA prints:
But I seem not to be able to get the job done. I got some leftover supports and wanted to throw them in the trash, so I put the lamp onto them, at less than 10 cm, over a cardboard box with foil paper in the walls, and accidentally forgot about it. After 5 hours I remembered, got back, and the resin was still sticky and not cured. Not to say that I should do this for both sides, so I don't think it's a good solution.
I tried another one, this time with the lamp in my hands, and put the lamp over the piece less than 3 cm away. I spent 3 rounds of 5 minutes (that's 15 min) with the lamp pointing directly at it (less than 3 cm away) and it was still not cured, either.
So I'm asking: am I doing something wrong? May my UV lamp be defective? Or is it normal to take so much time? Can you recommend any UV lamp that gets the job done and doesn't take forever?
I already have an Elegoo Mercury curing machine, but it hasn't enough room for big prints, that's why I want to get a lamp that I can use and adjust for bigger prints.
