[{"abstract":[{"lang":"eng","text":"Additive manufacturing of optical, electrical, and mechanical components is a beneficial approach for the rapid prototyping of components and error elimination, with short turnaround times. However, additively manufactured components usually have rough surfaces that need post-processing, particularly for optical components, where the surface roughness must be a small fraction of the wavelength. We demonstrate an innovative and economical approach by dip-coating with the same resin used for printing in a simple post-processing step, providing high transparency to the 3D-printed optical components and reducing surface roughness while achieving perfect index matching of the coating layer. The surface roughness of the 3D-printed optical components drops to 5 nm (arithmetic average) after the dip-coating process. We observed significant performance enhancements after comparing the unprocessed optical components and the dip-coated optical components, including optical transparency and a shiny surface finish for previously rough surfaces."}],"publication_status":"published","author":[{"id":"74090","full_name":"Shrotri, Abhijeet Narendra","first_name":"Abhijeet Narendra","orcid":"0000-0003-2116-156X","last_name":"Shrotri"},{"last_name":"Preu","full_name":"Preu, Sascha","first_name":"Sascha"},{"full_name":"Stübbe, Oliver","first_name":"Oliver","orcid":"0000-0001-7293-6893","last_name":"Stübbe","id":"51864"}],"publisher":"MDPI AG","issue":"2","publication":"Coatings : open access journal","status":"public","title":"Achieving Transparency and Minimizing Losses of Rough Additively Manufactured Optical Components by a Dip-Coating Surface Finish","intvolume":"        15","volume":15,"publication_identifier":{"issn":["2079-6412"]},"language":[{"iso":"eng"}],"_id":"12424","quality_controlled":"1","place":"Basel","article_number":"210","keyword":["additive manufacturing","post-processing","optics","dip-coating"],"doi":"10.3390/coatings15020210","department":[{"_id":"DEP5020"},{"_id":"DEP6020"}],"date_created":"2025-02-11T11:56:38Z","date_updated":"2025-02-12T08:37:34Z","user_id":"83781","type":"scientific_journal_article","citation":{"ama":"Shrotri AN, Preu S, Stübbe O.
