White marks on standard clear v5

[eyekey]

what could be causing these white marks on the clear resin?
there appears to be non on the support material, only the actual model.

printed on 4L
washed in wash L with TPM

3 min ultrasonic rinse.
30c water with a drop of dishwasher soap

i had a mild fan blowing at them to speed up dry before UV cure

I did have the degas option on the ultrasonic cleaner, would that have caused that?
Does anyone accurate times and settings for an ultra sonic cleaner rinse?

THanks,
Ryan

Hi @eyekey thanks for sharing and sorry you’re experiencing this.
The forum team reviewed this and we think the ultrasonic bath could be the culprit. Could you re-try printing this but skip the ultrasonic bath and swap for your water. w/soap combo.

As a review, here are our standard TPM washing steps.

Let us know how it goes!
