Andrew Terranova has come up with an excellent trick to save a 3D print that goes south during the printing process due to poor print bed adhesion, modeling errors, or improper slicing. Rather than tossing out the failed print and starting again, Terranova uses hot glue to pull the print back from the brink of disaster. The electrical engineer, writer, and electronics and robotics hobbyist uses the hot glue technique to fill in accidental gaps which might appear during printing.
