Resin flowed out outside on table, inside the printer, and the tank had too much resin


I have a printer “Form 3+” and used it to print many projects. Most with High Temp resin.

On Sunday I started printing a new project. Everything is as usual.
A few hours later I come to the room with the printer and see something very not good…

  • the resin flowed out and was on the table around the printer.
  • also, the tank with resin had too much resin inside.
  • and I see resin inside the printer space (space where the laser is moving)… and under inside…
  • the resin was even on the platform!
    Resin flowed out from the bottom and even from the top over the front panel.

But the printer still tries to print the project as normal.
It was not detect any errors/issues.

I stopped it (open cover). As I can see laser doesn’t have any resin on top (almost sure of that).

Before start print the project:

  1. the resin cartridge I did not change before starting this project, so it was successfully used before.
  2. as well, as a tank with resin.
  3. the project is not new. I printed the same objects before many times.

Why did that happen?
What do I need to do?
Possible to clean?

I’m very upset about this…
Please help…

Hi @andrii_bakulin,

I’m sorry to hear you’ve experienced a spill of this degree. Here is a guide on cleaning extensive resin spills to help get any excess resin out of the printer.

Opening a case with our Support Team will allow our team to investigate the diagnostic logs to see what may have played a part in this happening.

Thank you for your answer!
Yesterday I clean the printer. But only opening the front panel was not enough.
I open also side panels and bottom covers.
The resin was even on these places.

Then I return everything back and print the test project.
For now, looks good.

But I’m very worried about that → CleanShot 2023-07-19 at 15.28.43 · CleanShot Cloud
Bottom fan and the “device” over - where resin flowed out…
Maybe it’ll stop working 1-2 days/weeks/months later…

Also, it looks like resin in the fan - CleanShot 2023-07-22 at 10.57.17 · CleanShot Cloud

Hi Andrii.
I had the same thing happen to me. From what I could tell, it was the tank ‘float’. The little hammer-foot device inside the tank stuck to the bottom of the tank because it sat still for over 30days in a drawer. I didn’t think about it when I re-installed the tank and resin (Grey standard). it overflowed all over and it was so troublesome to get it cleaned again. I think I even replaced the LPU cover.
Now, before I print anything, I always jiggle the little float first, if it’s been sitting for a day or two… (like Mondays, when no one printed anything over the weekend). So far I haven’t had any more overflow issues.


Hi, @mwbarre1
Thank you for your advice!
I’ll keep it in mind for the future.
But for me, it’s not working because I used this tank a few days before.
