However, the application to glass powders, later subjected to viscous flow sintering, involves significant challenges, especially in shape retention and in the achievement of a substantial degree of translucency in the final products. The present paper disclosed the potential of glass recovered from liquid crystal displays (LCD) for the manufacturing of highly porous scaffolds by direct ink writing and masked stereolithography of fine powders mixed with suitable organic additives, and sintered at 950 \u00b0C, for 1\u20131.5 h, in air. The specific glass, featuring a relatively high transition temperature (Tg~700 \u00b0C), allowed for the complete burn-out of organics before viscous flow sintering could take place; in addition, translucency was favored by the successful removal of porosity in the struts and by the resistance of the used glass to crystallization.<\/jats:p>","DOI":"10.3390\/ma14175083","type":"journal-article","created":{"date-parts":[[2021,9,6]],"date-time":"2021-09-06T13:18:26Z","timestamp":1630934306000},"page":"5083","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Up-Cycling of LCD Glass by Additive Manufacturing of Porous Translucent Glass Scaffolds"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5550-6776","authenticated-orcid":false,"given":"Arish","family":"Dasan","sequence":"first","affiliation":[{"name":"Centre for Functional and Surface-Functionalized Glass, Alexander Dub\u010dek University of Tren\u010d\u00edn, \u0160tudentsk\u00e1 2, 911 50 Tren\u010d\u00edn, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulina","family":"O\u017c\u00f3g","sequence":"additional","affiliation":[{"name":"Centre for Functional and Surface-Functionalized Glass, Alexander Dub\u010dek University of Tren\u010d\u00edn, \u0160tudentsk\u00e1 2, 911 50 Tren\u010d\u00edn, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jozef","family":"Kraxner","sequence":"additional","affiliation":[{"name":"Centre for Functional and Surface-Functionalized Glass, Alexander Dub\u010dek University of Tren\u010d\u00edn, \u0160tudentsk\u00e1 2, 911 50 Tren\u010d\u00edn, Slovakia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9818-4498","authenticated-orcid":false,"given":"Hamada","family":"Elsayed","sequence":"additional","affiliation":[{"name":"Ceramics Department, National Research Centre, Cairo 12622, Egypt"},{"name":"Department of Industrial Engineering, University of Padova, 35131 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2914-5962","authenticated-orcid":false,"given":"Elena","family":"Colusso","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, University of Padova, 35131 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7041-1794","authenticated-orcid":false,"given":"Luca","family":"Grigolato","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, University of Padova, 35131 Padova, Italy"},{"name":"Department of Civil, Environmental and Architectural Engineering: Dept.
