Towards this goal, different hose geometries were additively manufactured using Fused Layer Manufacturing techniques of Thermoplastic Polyurethane Elastomer. Material properties of the elastomer were studied using Differential Scanning Calorimetry and the tensile test. The relations between the sample\u2019s print temperature and build direction on the actuator endurance were investigated. Lastly, the relation between the geometry design of the PLPA actuator and its endurance is also discussed. Based on this methodology, authors present results showing that the use of a customized shaped hose with geometrical reinforcement at sides leads to a considerable rise in the hose endurance, when compared with the conventional circular design.<\/jats:p>","DOI":"10.3390\/act10070161","type":"journal-article","created":{"date-parts":[[2021,7,15]],"date-time":"2021-07-15T09:32:07Z","timestamp":1626341527000},"page":"161","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Additive Manufacturing of Flexible Material for Pneumatic Actuators Application"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8879-9272","authenticated-orcid":false,"given":"Miranda","family":"Fateri","sequence":"first","affiliation":[{"name":"Faculty Mechanical Engineering & Materials Science, Aalen University, Beethovenstra\u00dfe 1, 73430 Aalen, Germany"}]},{"given":"Jo\u00e3o Falc\u00e3o","family":"Carneiro","sequence":"additional","affiliation":[{"name":"LAETA-INEGI, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, s\/n, 4200-465 Porto, Portugal"}]},{"given":"Achim","family":"Frick","sequence":"additional","affiliation":[{"name":"Institute of Polymer Science and Processing (iPSP), Aalen University, Beethovenstra\u00dfe 1, 73430 Aalen, Germany"}]},{"given":"Jo\u00e3o Bravo","family":"Pinto","sequence":"additional","affiliation":[{"name":"LAETA-INEGI, University of Porto, Rua Dr. Roberto Frias, s\/n, 4200-465 Porto, Portugal"}]},{"given":"Fernando","family":"Gomes de Almeida","sequence":"additional","affiliation":[{"name":"LAETA-INEGI, Faculty of Engineering, University of Porto, Rua Dr. Roberto Frias, s\/n, 4200-465 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1073","DOI":"10.1021\/acsapm.9b01078","article-title":"Reinforced Gels and Elastomers for Biomedical and Soft Robotics Applications","volume":"2","author":"Zhalmuratova","year":"2020","journal-title":"ACS Appl.
