Filament absorbs moisture as soon as you break the seal of the packaging, and that moisture will affect the quality of your prints, and it’s a problem that until recently no one talked about. The effect of damp filament, even if it feels dry to the touch, shows up as stringing, popping, weak layer adhesion, and prints that just look slightly worse than they should. Because it creeps in gradually, you usually blame the printer, whereas it’s often the material.The H1 HT is Elegoo’s first dryer. It arrives to tackle one of the major quibbles with the otherwise excellent Centauri Carbon 2 (see my review here). Essentially, the fact that the machine features an open-air spool design, leaving filament exposed to whatever humidity the room happens to have. In the case of my workshop at some points of the year, that can be high. This drybox is the company’s answer….
