Problems with Grey Resin V4


#1

Hi,

I’m still using a Form 1+, recently I bought new resin grey v4 (my last bottle was grey v2). I used a new tank for the new resin, first print came out perfect and after that a bunch of fails. same model, same orientation and everything, I checked the mirrors, they were clean, the tank is new. After about 5 bad prints I was able to print 4 ou 5 parts fine, and now its failing again. I have no idea what to do. When it fails I try new orientation of the model, but the results seem random.
Anyone else with the same problem?
I notice that this resin makes a lot more bubbles than the previous one (grey v2). Is it normal?

Patricia:
You are not the first person to complain about V4 on this forum. In my opinion it is an inferior product compared with V3 (never tried V2). I have switched to a 3rd party resin for grey. If you use the forum search feature and type in “grey V4” you will find many threads like this:

Yes, I read some of the complaints like mine.
What 3rd party resin do you recommend?

I’ve bought 1 litre of Digital Forge last resin last year and it’s not as good as V3 but a lot better than V4. But it has a stronger odour than the formlabs resins. A couple of months ago Digital Forge announced they have a new improved formulation for their grey which I’ll probably try soon as my current supply is almost gone. I should add, if you are printing large parts at the lower resolutions V4 can work, in my case everything I’m doing is very small and highly detailed so I need the highest resolution.

I haven’t tried it, but a lot of people on this forum have gone over to dental model resin instead of standard grey.
