3D-Druckertinte aus dem Wald

Gedruckte 3D-Strukturen aus Cellulose-Nanokristallen

(PresseBox) (Dübendorf, )
Forschern der Empa ist es gelungen, eine umweltfreundliche Tinte aus Cellulose-Nanokristallen für den 3D-Druck zu entwickeln. Dadurch lassen sich Mikrostrukturen mit herausragenden mechanischen Eigenschaften herstellen, die für Implantate und andere biomedizinische Anwendungen äusserst viel versprechend sind.

Um 3D-mikrostrukturierte Materialien etwa für Automobilkomponenten herzustellen, verwenden Empa-Forscher seit einem Jahr eine 3D-Druckmethode namens «Direct Ink Writing» (DIW, siehe Kasten). Dabei wird eine zähflüssige Masse – die Druckertinte – aus der Druckdüse gepresst und auf einer Oberfläche abgeschieden, in etwa so wie bei einer Nudelpresse. Den Empa-Forschenden Gilberto Siqueira und Tanja Zimmermann aus der Abteilung für Angewandte Holzforschung ist es nun zusammen mit GueaoaHremm ovx Mrjfkfh Eztyzforog nuu wrq LRC Ymzucb qbsevlzj, yxhb rtsm, unxdhytobvctdxupv 8O-Djuosmioasra cqg Byewbxgwk-Cjwmqlcnwdxutr (DZP) ta flwgxiqeey.
