Optimized extruder heaters reduce dual head printing time in half
More powerfull and homogeneous power enables extruder plastic to cool down faster and more evenly allowing better defined print details and overhang printing
due to better temperature stability in heater blocks and also more accurate geometry of extruder assembly
due to virtually no color bleeding with the variable print-head height system.
*Overhang = the angle of the object with respect to the build platform. The smaller the angle the better it is.
