Abstract
In one example, a build material supply system for additive manufacturing includes a mixer to aperiodically rotate a non-circular mixing chamber containing powdered build material to form mixed powdered build material.
Claims14
A powdered build material supply system for additive manufacturing, comprising:
- a mixer;
- and
- a controller operatively connected to the mixer to rotate the mixing chamber aperiodically by varying an angular displacement of the mixing chamber aperiodically during a series of rotation cycles, by varying an angular speed of the mixing chamber aperiodically during the series of rotation cycles, and/or by varying a direction of rotation of the mixing chamber aperiodically during the series of rotation cycles.
A build material supply system for additive manufacturing, comprising:
- a mixer to aperiodically rotate a non-circular mixing chamber containing powdered build material to form mixed powdered build material;
- and
- a dispenser operatively connected to the mixer to dispense mixed powdered build material for fusing.
A processor readable medium having mixing instructions thereon that when executed cause a mixer in an additive manufacturing machine to rotate a non-circular mixing chamber aperiodically by varying an angular displacement of the mixing chamber aperiodically during a series of rotation cycles, by varying an angular speed of the mixing chamber aperiodically during the series of rotation cycles, and/or by varying a direction of rotation of the mixing chamber aperiodically during the series of rotation cycles.
