The original Federica hand has a complicated, time-consuming assembly process. The print-in-place design removes the process of assembling the hand, making it easier for new users to use the design. The approach results in a 21% reduction in the bill of materials and a 21% reduction in weight. Though the 8 N force of the original Federica hand was not reached in this trial, the measured results show that under the same test conditions, the print-in-place hand can match the performance of the original. In a single-specimen analysis, the print-in-place hand produced a higher peak force in four of eight orientations. The redesigned prosthetic hand includes functional joints fully integrated into its structured design with a locking mechanism, eliminating the need for several metal bolts, and a revised dorsal finger contour, reducing the requirement for additional support structures during printing. As with the original hand, the print-in-place prosthetic is open source for anyone to access.<\/jats:p>","DOI":"10.3390\/bioengineering13090998","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T16:47:13Z","timestamp":1787849233000},"page":"998","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Simplified Print-in-Place Redesign of the Open-Source Federica Prosthetic Hand"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9960-5346","authenticated-orcid":false,"given":"Levi","family":"Tynan","sequence":"first","affiliation":[{"name":"School of Engineering, Design and Built Environment, Western Sydney University, Penrith, NSW 2751, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osura","family":"Perera","sequence":"additional","affiliation":[{"name":"School of Engineering, Design and Built Environment, Western Sydney University, Penrith, NSW 2751, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Purss","sequence":"additional","affiliation":[{"name":"School of Engineering, Design and Built Environment, Western Sydney University, Penrith, NSW 2751, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-8404-097X","authenticated-orcid":false,"given":"Benjamin","family":"Brandwood","sequence":"additional","affiliation":[{"name":"School of Engineering, Design and Built Environment, Western Sydney University, Penrith, NSW 2751, Australia"},{"name":"The MARCS Institute for Brain, Behaviour and Development, Western Sydney University, Penrith, NSW 2751, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0716-8431","authenticated-orcid":false,"given":"Daniele","family":"Esposito","sequence":"additional","affiliation":[{"name":"Department of Information and Electrical Engineering and Applied Mathematics, University of Salerno, Via Giovanni Paolo II, 132, I-84084 Fisciano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0932-5306","authenticated-orcid":false,"given":"Upul","family":"Gunawardana","sequence":"additional","affiliation":[{"name":"School of Engineering, Design and Built Environment, Western Sydney University, Penrith, NSW 2751, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5055-0770","authenticated-orcid":false,"given":"Ranjith","family":"Liyanapathirana","sequence":"additional","affiliation":[{"name":"School of Engineering, Design and Built Environment, Western Sydney University, Penrith, NSW 2751, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2616-2804","authenticated-orcid":false,"given":"Gaetano","family":"Gargiulo","sequence":"additional","affiliation":[{"name":"School of Engineering, Design and Built Environment, Western Sydney University, Penrith, NSW 2751, Australia"},{"name":"The MARCS Institute for Brain, Behaviour and Development, Western Sydney University, Penrith, NSW 2751, Australia"},{"name":"Translational Health Research Institute, Western Sydney University, Penrith, NSW 2751, Australia"},{"name":"The Ingham Institute for Applied Medical Research, Liverpool, NSW 2170, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Caldas, A., Matos, D., de Eyto, A., and Martins, N.
