I recently had problems with the big mirror and the galvo mirrors due to dust in my form 1+. I was wondering: what if I place a borosilicate glass of around 2.5/3 mm underneath to avoid dust going on the mirrors? I was thinking something like this: http://www.kitprinter3d.com/en/heated-bed/109-cristal-de-borosilicato.html . Might be a good idea or that’s the worst one you ever heard? Checking at the optical transmission I shouldn’t have any problem with the laser, it should pass the glass smoothly.
@Jeffrey_dube the printer is placed on my desk and that’s the only spot where I can have it. Therefore, the only solution for me is to find an “internal” way to avoid dust.
I wouldn’t say it’s the worst idea I’ve ever heard, especially considering that the Form 2 has a glass window beneath the tank that helps keep dust off the mirror
With your idea, you would likely run into power loss problems. These glasses tend to have transmissivities around 90%. A 10% power loss at the surface of the tank would cause print problems, as the parts would be underexposed.
@CraigBroady Actually I didn’t know about the glass window in the Form 2! That’s a sign, I have to work for formlabs, we are on the same wavelength. I’m just about a year late!!! Is it the glass window made out of borosilicate? Anyway thanks for your answer, I would maybe go for a solution as @Jeffrey_dube suggested.
