ABS Water Content Test Tube

youmagine

Set layer height to 0.3 mm for single wall prints.\n\nPrint just one section of this tube to figure out if your filament needs drying time. If you notice the base shrinking during print, it's a sign that water is being removed from the plastic by the heated bed. You can dry out the filament in a conventional oven set at its lowest temperature for 2 to 4 hours to remove excess moisture.
