In the current industry, proposing a cost-effective approach to the manufacture of polymer gears is an important research issue. This paper investigates the wear performance of polymer gears fabricated with eight different kinds of materials using differential pressure vacuum casting and additive manufacturing techniques. It was found that both additive manufacturing and differential pressure vacuum casting seem to be an effective and cost-effective method for low-volume production of polymer gears for industrial applications. The gate number of one is the optimal design to manufacture a silicone rubber mold for differential pressure vacuum casting since the weld line of the polymer is only one. Polyurethane resin, 10 wt.% glass fiber-reinforced polylatic acid (PLA), or 10 wt.% carbon fiber-reinforced PLA are suggested for manufacturing gears for small quantity demand based on the deformation and abrasion weight percentage under process conditions of 3000 rpm for 120 min; epoxy resin is not suitable for making gears because part of the teeth will be broken during abrasion testing.<\/jats:p>","DOI":"10.3390\/polym13234126","type":"journal-article","created":{"date-parts":[[2021,12,1]],"date-time":"2021-12-01T02:34:05Z","timestamp":1638326045000},"page":"4126","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Characterizations of Polymer Gears Fabricated by Differential Pressure Vacuum Casting and Fused Deposition Modeling"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0519-4126","authenticated-orcid":false,"given":"Chil-Chyuan","family":"Kuo","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Ming Chi University of Technology, No. 84, Gungjuan Road, New Taipei City 243, Taiwan"},{"name":"Research Center for Intelligent Medical Devices, Ming Chi University of Technology, No. 84, Gungjuan Road, New Taipei City 243, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ding-Yang","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Ming Chi University of Technology, No. 84, Gungjuan Road, New Taipei City 243, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhe-Chi","family":"Lin","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Ming Chi University of Technology, No. 84, Gungjuan Road, New Taipei City 243, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhong-Fu","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Ming Chi University of Technology, No. 84, Gungjuan Road, New Taipei City 243, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Polanec, B., Zupani\u010d, F., Bon\u010dina, T., Ta\u0161ner, F., and Glode\u017e, S.
