1. A computer-implemented method for performing corrective operations during a three-dimensional (3D) printing job, the method comprising:
initiating the 3D printing job to produce a physical object;
monitoring printing of the physical object to identify a defect of the physical object during the printing, wherein the defect includes a weak bonding of adjacently-deposited layers of the physical object;
analyzing the defect to determine one or more corrective operations to apply to the physical object; and
performing the one or more corrective operations during the printing, wherein the one or more corrective operations include laser drilling a plurality of spaces that each pass through at least a portion of both of the adjacently-deposited layers and inserting a pin into each space, and wherein the plurality of spaces and the pin in each space are at different angles from each other with respect to the physical object.
