This feasibility study developed and evaluated a clinician-accessible protocol for fabricating cock-up wrist splints using 3D scanning (Creaform GO!SCAN 50 with VXelements 4.1), modeling (Materialise Magics), and fused deposition modeling printing with polylactic acid (PLA) on a MakerBot Replicator+. Five healthy participants wore the splints for one week, with user satisfaction assessed via the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST 2.0; average total score 4.14\/5, range 3.75\u20134.42) questionnaire. An experienced occupational therapist provided expert feedback. High satisfaction was reported for weight (4.6\/5) and ease of use (4.6\/5), confirming advantages over traditional thermoplastic splints in lightness and esthetics. However, lower scores for durability (3.6\/5), comfort (3.6\/5), and effectiveness (3.6\/5) stemmed from PLA brittleness (cracking under load or overtightening), rough surfaces despite vapor polishing, inadequate ventilation causing moisture buildup, and fit issues (e.g., pressure points). Printing time averaged 9\u201319 h per splint. The protocol demonstrates proof-of-concept feasibility for clinicians with basic computer techniques, but material constraints and process refinements are required for reliable application in patient populations.<\/jats:p>","DOI":"10.3390\/ma19061146","type":"journal-article","created":{"date-parts":[[2026,3,16]],"date-time":"2026-03-16T08:41:26Z","timestamp":1773650486000},"page":"1146","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Feasibility Study of Splintage by 3D Scanning and Printing: Process and Evaluation of Current 3D Printing Material"],"prefix":"10.3390","volume":"19","author":[{"given":"Sze Wai Anson","family":"Li","sequence":"first","affiliation":[{"name":"Department of Rehabilitation Sciences, The Hong Kong Polytechnic University, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sze Wa Afra","family":"Mok","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Sciences, The Hong Kong Polytechnic University, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sze Wing","family":"Wong","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Sciences, The Hong Kong Polytechnic University, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-1912-4772","authenticated-orcid":false,"given":"Bohao","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Sciences, The Hong Kong Polytechnic University, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3182-9041","authenticated-orcid":false,"given":"Jackie Ngai-Man","family":"Chan","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Sciences, The Hong Kong Polytechnic University, Hong Kong, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5909-4847","authenticated-orcid":false,"given":"Kenneth N.
