The filament is in a controlled environment without possibility of hydration to occur but I do understand where you're coming from. I have now solved the issue and the same spool is printing fine. I appreciate the help

<p>I encountered a case of pillowing throughout several layers that was very severe, however, I managed to fix it through adjusting the temperatures but I was wondering if anyone could tell me if there any any other cases of this and if they have found a trustworthy way to solve the problem if it occurs repeatedly as it has slowly started to re-appear in different prints after I have rectified the problem, and I haven't altered any of the previous settings I altered to fix it.</p>

Can you include a pic? "Pillowing" and "bubbling" are very different things the way I normally use the terms, so it would help to distinguish what you mean.

How many top layers do you use at what thickness per layer?

it was a 5 layer print as it would be taking some abuse, I'm using it as an insert for draws to keep tools tidy

Without an example photo, it's difficult to be certain, but moisture in a filament spool can cause undesired effects in a print. Even a new-in-the-box, vacuum-sealed-plastic-bag spool can present these effects.

Consider to perform a [dehydration](https://lmgtfy.app/?q=how%20to%20dry%203d%20printer%20filament) on your filament and create another test print.
