Loop Variable Timer For Additive Manufacturing
A print engine of an additive manufacturing system can include an XY galvo arranged to direct a laser beam toward multiple positions on a print bed following a print path. In one embodiment an XY gantry supporting the XY galvo is connected to a motion control system that supports dynamic adjustment of the cycle time for both the XY gantry and XY galvo.
1 . A print engine of an additive manufacturing system, comprising
an XY galvo arranged to direct a laser beam toward multiple positions on a print bed following a print path;
an XY gantry supporting the XY galvo; and
a motion control system for the XY gantry and XY galvo that supports dynamic adjustment of cycle time.
2 . The print engine of the additive manufacturing system of claim 1 , further comprising a laser able to direct a two dimensional laser image against the print bed.
3 . The print engine of the additive manufacturing system of claim 1 , wherein the print bed is a powder bed.
4 . The print engine of the additive manufacturing system of claim 1 , wherein the print path is defined at least in part according to a pattern that is to be printed.
5 . The print engine of the additive manufacturing system of claim 1 , wherein the print path is at least in part serpentine.
6 . A print engine of an additive manufacturing system, comprising
an XY galvo arranged to direct a laser beam toward multiple positions on a print bed;
an XY gantry supporting the XY galvo; and
a motion control system for the XY gantry and XY galvo that controls movement to provide a serpentine pattern over tiles having patterns to be printed.
