Abstract
Methods of infiltrating a three-dimensional part with a resin are disclosed. The methods include designing a part to be printed, the part having at least one inlet and an infill pattern. The methods include using three-dimensional printing to print the designed part. The methods further include infiltrating the printed part using a resin delivered to an interior of the part via the at least one inlet to surround the infill pattern with the resin. The methods additionally include allowing the infiltrated resin to cure.
Claims20
A method of infiltrating a three-dimensional part with a resin, comprising:
- designing a part to be printed, the part having an inlet and infill patterns comprising one or more of a triangular infill, a hexagonal infill, a rectangular infill, and a gyroid infill, wherein the infill patterns further comprise surface patterning features extending along at least one channel thereof in a Z-direction of the part;
- using three-dimensional printing to print the designed part;
- infiltrating the printed part using a resin delivered to an interior of the part via the inlet to surround the infill patterns with the resin;
- and
- allowing the infiltrated resin to cure.
A method of infiltrating a three-dimensional part with a resin, comprising:
- using three-dimensional printing to print a designed part having reinforcement in an X-Y plane and infill patterns comprising one or more of a triangular infill, a hexagonal infill, a rectangular infill, and a gyroid infill, wherein the infill patterns further comprise surface patterning features extending along at least one channel thereof in a Z-direction of the part;
- printing continuous reinforcement in a Z-direction across one or more layers of the part;
- printing a final layer including an inlet and an outlet of the part;
- infiltrating the printed part using a resin delivered to an interior of the part via the inlet to surround the reinforcement in the X-Y plane, the continuous reinforcement in the Z-direction, and the infill patterns with the resin;
- and
- allowing the infiltrated resin to cure.
