HEXA Printer Issues
08/31/2023 at 09:34 • 0 comments

Too many degrees of freedom prevent positional accuracy at the nozzle tip. For example, the figure below shows a heat map of nozzle tip position error for different rotation angles at the same tilt angle.

Tilt 30 degrees, rotation 60 degrees

Tilt 30 degrees, rotation 240 degrees

The error varies depending on the angle of tilt and rotation.

(1) Reduction of support infill by printing diagonally.
(2) Improved lamination strength.
(3) Realization of stacking considering the direction of load.
(4) Improvement of surface properties.
