Filament Drying

Add an AMS HT only if you print materials that need more heat than the 2 Pro can deliver. The original AMS only makes sense if you find it discounted and you print PLA and PETG. Each unit is a feeder, a sealed storage box, and in two cases a dryer. For functional parts, the dryer matters more than the color count. ...

Water absorbed into the plastic turns to steam in the hot end. Prusa’s drying guide says high moisture content can cause low layer adhesion, blobs on the prints, and bubbling and smoke during extrusion. Layer adhesion is already the weak axis of an FDM part, and TDS numbers are measured on ideal specimens, so you don’t want to give up more Z-strength to steam voids. ...
