3D Printing of the Colorado State Building
Dual extruder 3D printing can save time and money. Utilizing the HFA extruder for fine exterior printing and the HFE 300 for quick infill, we saw a savings of 15 hours and a 6 lb of filament.
Size: X: 698mm Y: 841mm Z: 546mm
Printer Type: WorkSeries 400
HFA Extruder: Wall Extrusion
HFE 300 Extruder*: Infill Extrusion
Nozzle: 0.6mm (HFA), 1.0mm (HFE 300)
Layer Height: 0.3mm
Print Speed: 125mm/s
Print Time: 100 hours
*Printing the infill with the HFE 300 extruder with a 1.0 mm nozzel instead of the HFA extruder with the 0.6 mm nozzle saved 15 hours of print time and 6 lb of filament.
(The 1.0 mm nozzle only required an infill of 7% density instead of a minimum of 12% the HFA would have required)
