3D printed damper on the head gimbal assembly of a hard disk drive
A process to 3D print a damping material on the head gimbal assembly of a hard disk drive to reduce vibrations.

Researchers at the University of Minnesota have developed a process to 3D print damping materials on the head gimbal assembly (HGA) of hard disk drives. The 3D process allows for multi-material printing and precise control over the positioning and thicknesses of these materials. By depositing a material with specific mechanical properties at the desired locations on the HGA, critical frequencies can be dampened. This provides a novel and versatile solution for the design and manufacturing of HGAs with improved dynamic response.
Phase of DevelopmentTRL: 4-5
A prototype has successfully printed viscoelastic materials on head gimbal assemblies and demonstrated the enhanced performance of this solution.
