I'll be honest....
My printer was a bit quieter while printing.
The print came out looking generally much better than previously.
The layers were more uniform compared to previous prints of the same part.
The only issue I had was actually because one of the parts I printed (I printed 4 parts at once) didn't adhere during the first layer very well, which made little bits of plastic stick to the hot end and eventually they adhered to one of the other parts, causing some differences with 1 of the other parts.
Outside of that, they printed much better than the same parts I printed right before the hot glue.
I would suggest it.
As a side note, I wasn't very careful when applying the hot glue. Some of it touched the slides, which slightly adhered then. I moved all the pieces around and then slowly removed a little bit of hot glue around the areas that had adhered with a scalpel. This worked very well and it meant I didn't need to be extra careful when applying the hot glue.
