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.

A method of infiltrating a three-dimensional part with a resin, comprising:
- designing a part to be printed, the part having at least one inlet and an infill pattern;
- 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 at least one inlet to surround the infill pattern 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;
- printing continuous reinforcement in a Z-direction across one or more layers of the part;
- printing a final layer including at least one inlet and at least one outlet;
- infiltrating the printed part using a resin delivered to an interior of the part via the at least one inlet to surround the reinforcement in the X-Y plane and the continuous reinforcement in the Z-direction with the resin;
- and
- allowing the infiltrated resin to cure.
