Abstract
The present disclosure provides a method of forming an overhang for a three-dimensional printed part. The method includes ejecting one or more drops of a print material to create a preform onto a top layer of a three-dimensional printed part where the preform is oriented at an angle of 60 degrees or greater relative to a print bed in a first dimension, and bending the preform to form the overhang having an angle of less than 90 degrees relative to the print bed, and where no portion of the preform contacts the print bed. A printing system for executing a method of forming an overhang for a three-dimensional printed part is also disclosed.
Claims21
A method of forming an overhang for a three-dimensional printed part, comprising:
- ejecting one or more drops of a print material to create a preform onto a top layer of a three-dimensional printed part wherein the preform is oriented at an angle of 60 degrees or greater relative to a print bed in a first dimension;
- and
- bending the preform to form the overhang having an angle of less than 90 degrees relative to the print bed;
- and
- wherein no portion of the preform contacts the print bed.
A method of forming an overhang for a three-dimensional printed part, comprising:
- ejecting one or more drops of a print material to create a preform onto a top layer of a three-dimensional printed part;
- wherein:
- the preform is oriented at an angle of 60 degrees or greater relative to a print bed in a first dimension;
- and
- the preform comprises a ductile hinge, comprising one or more pillars;
- and
- bending the preform to form the overhang having an angle of less than 90 degrees relative to the print bed, wherein no portion of the preform contacts the print bed.
A printing system, comprising:
- an ejector for jetting a print material, comprising:
- a structure defining an inner cavity;
- and
- a nozzle orifice in connection with the inner cavity and configured to eject one or more droplets of liquid print material;
- wherein:
- the ejector is configured to form an overhang for a three-dimensional printed part, comprising:
- one or more drops to create a preform onto a top layer of a three-dimensional printed part wherein the preform is oriented at an angle of 60 degrees or greater relative to a print bed in a first dimension;
- and
- wherein no portion of the preform contacts the print bed.
