3D-Printed Ergonomic Tool Handles

Although hand tools serve as an instrument for extending one’s capabilities through the use of hands, comfort it brings is important especially since welfare user at stake. Aside from using repetitively and with awkward posture, tool handle compositions design also contribute to accumulating some work-related musculoskeletal disorders that require further attention in long run. To provide a long-term solution, 3D-printed new designs six commonly used fit average measurements Filipinos have been developed. The are printed two filaments namely; thermoplastic polyurethane (TPU) which was found be skin-friendly polylactic acid (PLA) proven more functional, both on outer inner layer handle, respectively. handles were evaluated questionnaire distributed 10 respondents per testing, results show comfortable convenient rather than commercial ones. Meanwhile, researchers note adequate length may vary according functions not rely alone measurements.
