Specimens were subjected to three-point flexural strength, Vickers hardness, water sorption, solubility, and color stability tests. Color stability was evaluated under dry (A), water-immersed (B), light-shielded (C), and light-exposed (D) conditions, and color differences (\u0394E00) were calculated using the CIEDE2000 formula. Data were analyzed using Student\u2019s t-test or Welch\u2019s t-test, as appropriate (\u03b1 = 0.05). Flexural strength and Vickers hardness were significantly higher, and solubility was significantly lower, in the 385 nm group than in the 405 nm group (p &lt; 0.05), whereas water sorption did not differ significantly. The \u0394E00 values were below the clinically acceptable threshold of 1.77 for all comparisons except A\u2013B in the 405 nm group. The A\u2013B and A\u2013C values were significantly lower in the 385 nm group, whereas the B\u2013C value was significantly higher (p &lt; 0.05); no significant difference was observed for C\u2013D. These findings suggest that differences between printer systems, including light-source wavelength, should be considered when fabricating dental prostheses using 3D printing resins.<\/jats:p>","DOI":"10.3390\/ma19194140","type":"journal-article","created":{"date-parts":[[2026,9,28]],"date-time":"2026-09-28T12:46:29Z","timestamp":1790599589000},"page":"4140","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Physical Properties of a Filler-Containing Dental 3D Printing Resin Processed Using Printer Systems with Different Light-Source Wavelengths"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-6791-431X","authenticated-orcid":false,"given":"Norihiro","family":"Sasamoto","sequence":"first","affiliation":[{"name":"Department of Dental Material Science, Division of Oral Functional Science and Rehabilitation, Asahi University School of Dentistry, Hozumi 1851, Mizuho 501-0296, Gifu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"}]},{"given":"Takashi","family":"Horiguchi","sequence":"additional","affiliation":[{"name":"Department of Dental Material Science, Division of Oral Functional Science and Rehabilitation, Asahi University School of Dentistry, Hozumi 1851, Mizuho 501-0296, Gifu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"}]},{"given":"Kohei","family":"Shintani","sequence":"additional","affiliation":[{"name":"Department of Dental Material Science, Division of Oral Functional Science and Rehabilitation, Asahi University School of Dentistry, Hozumi 1851, Mizuho 501-0296, Gifu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0062-5495","authenticated-orcid":false,"given":"Katsushi","family":"Okuyama","sequence":"additional","affiliation":[{"name":"Department of Operative Dentistry, Division of Oral Functional Science and Rehabilitation, Asahi University School of Dentistry, Hozumi 1851, Mizuho 501-0296, Gifu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"}]},{"given":"Yukimichi","family":"Tamaki","sequence":"additional","affiliation":[{"name":"School of Dentistry, Asahi University, Hozumi 1851, Mizuho 501-0296, Gifu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"supervision","vocabulary":"credit"},{"role":"project-administration","vocabulary":"credit"},{"role":"conceptualization","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4937-7111","authenticated-orcid":false,"given":"Tomofumi","family":"Sawada","sequence":"additional","affiliation":[{"name":"Department of Dental Material Science, Division of Oral Functional Science and Rehabilitation, Asahi University School of Dentistry, Hozumi 1851, Mizuho 501-0296, Gifu, Japan"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"381","DOI":"10.1016\/j.prosdent.2022.06.008","article-title":"Mechanical properties of 3D printed prosthetic materials compared with milled and conventional processing: A systematic review and meta-analysis of in vitro studies","volume":"132","author":"Valenti","year":"2024","journal-title":"J.
