Hey everyone,
Thank you very much for taking the time to contribute and raise the issue. We have seen a rise in bite valves falling off of cartridges in the last few weeks and identified and resolved the root cause. This problem should not appear with anything near the same frequency moving forward.
In terms of folks currently experiencing this problem, whether it led to a resin spill during shipping, or during the printing, please reach out to support at the link below and we’d be more than happy to help get you back to printing as efficiently as possible.

For anyone who hasn’t experienced this problem yet, but is rightly concerned about it happening to you, there’s a pretty easy step you can take to protect yourself. When you start a new cartridge of resin, press down on the bite valve firmly with your thumb to make sure it’s securely attached to the floor of the cartridge. We’ve found that this simple procedure will prevent cartridges that would have leaked from having any problems at all.
Below you’ll find a picture of a bite valve that has not been pushed down yet, and would very likely lead to a spill. You’ll see that orange cover is a little bit above the two black wings next to it. The valve should be flush with those wings.
Again, I want to apologize for any trouble this issue has caused. If you have any additional concerns please feel free to ask here, or reach out to our support team.
