Ditto Dualstrusion

thingiverse

Printing with dual-strusion PLA often leads to issues due to ooze from the idle nozzle; however, a workaround exists for narrow objects. By alternating STLs of dual halves and using Ditto Printing in Sailfish firmware, both nozzles can be utilized simultaneously, increasing print speed. This method allowed me to produce 60 bearings on my Rep1 during Makerfaire in just two days. Customization involves specifying accurate x- and y-offsets of nozzles within 0.1mm, which can be determined using a test object or calibration script. Despite ending up with half-objects at each end, multiple completed objects can still fit on the build plate. This technique is not limited to bearings; open my OpenSCAD code for detailed implementation information.
