Dual Cooling Duct

thingiverse

To accommodate ABS printing without cooling, I opted for a removable mount on my modified AirWolf XL3D equipped with a second Budaschnozzle. This modification allows me to independently cool each nozzle when working with multiple materials in the same build, such as ABS and TPE or ABS with PVA support. The fans use standard 40mm parts with 3mm nuts/bolts. For printing, I typically use a speed of 80mm/s, but for projects with steep overhangs, I slow down. With layer settings at 0.2, 1 perimeter, and 3 top and bottom layers, fill density is set to 0.4, perimeter speed at 25mm/s, and infill speed at 40mm/s. The hot end temperature is maintained at 240°C (first layer at 260°C), while the bed temperature remains at 115°C. As a result, 4.26 meters of 3mm filament were used in this project, equating to 27.2 cubic centimeters of material.
