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.

Abstract: A 3D printing apparatus and method prints a partial part, and continues to print the part after the partially-printed part has been rotated. Each partial printing operation may include reinforcement via application of one or more layers of continuous fiber. The rotation and continued printing of the partially-printed part allows for fiber orientation in different orientations for the printed part.

Abstract: Method of manufacturing a metal matrix composite part and ceramic preform assembly for use in the method. The method includes forming a ceramic preform using 3D printing, sintering the ceramic preform to form a sintered preform, introducing a liquid metal into the sintered preform to form the metal matrix composite part. The ceramic preform may be part of a ceramic preform assembly includes at least one ceramic preform and an infiltrant reservoir connected to the ceramic preform. The method may also include forming the ceramic preform assembly using 3D printing.

Abstract: A 3D printing apparatus and method corrects for skew in the motion components of the apparatus without the use of an independent reference object. A calibration object having features therein or thereon is printed. A user rotates the calibration object by a certain angle after it is printed. The features in/on the calibration object are measured, and an amount of skew is determined based on the measurements. In addition, a 3D printing operation is compensated based on the effects of a coefficient of thermal expansion and/or moisture absorption on dimensional changes.
