Left: I opened a sealed roll of a filament purchased in 2018 and I printed that rose
Right: I dried that filament in the creality dryer overnight and sent the print again
This pic was taken on 10th April. After drying the filament I put it back in storage and I forgot about it until it exploded today
I live in southern AZ where it is super dry. I never though I needed a filament dryer. I got one anyways and it turns out I did need one. My print are so much better now. Would recommend.
