Enclosure for print performance?

If I get an enclosure for my Prusa, will I get better print performance?

Not out of PLA but maybe out of ABS. What filaments are you printing with?

If you do go the enclosure route with your Prusa you should consider the Ikea lack table enclosure. It is easy, popular, and there are plenty of walk throughs and specific hardware kits just for this effort. Here is a walkthrough on the v2 from a Prusa blog: Prusa Printer Enclosure V2 - with MMU2S support - Prusa Printers

I would suggest the enclosure can help with your print performance, but it certainly will improve the 3D print experience overall. Here are a few that I make: https://clearviewplastic.com/
