Using Heat Set inserts with 3D printed thermoplastics

Heat-set inserts are perfect for thermoplastics in 3D printing because during installation the thermoplastic melts and reflows around the insert. This makes the plastic surrounding the insert locally stronger, and establishes a secure bond between the metal insert and the thermoplastic. This in turn ensures a much stronger pull-out and torque-out rating of the resulting thread as compared to other types of inserts.
