Thermoelectric (TE) generators can power those systems by converting abundant waste heat into electricity, whereas the versatility of additive manufacturing suits heterogeneous form factors. Here, additive manufacturing of high\u2010performing flexible TEs is proposed. Maskless and large\u2010area patterning of Bi<jats:sub>2<\/jats:sub>Te<jats:sub>3<\/jats:sub>\u2010based films is performed by laser powder bed fusion directly on plastic foil. Mechanical interlocking allows simultaneous patterning, sintering, and attachment of the films to the substrate without using organic binders that jeopardize the final performance. Material waste could be minimized by recycling the unexposed powder. The particular microstructure of the laser\u2010printed material renders the\u2014otherwise brittle\u2014Bi<jats:sub>2<\/jats:sub>Te<jats:sub>3<\/jats:sub> films highly flexible despite their high thickness. The films survive 500 extreme\u2010bending cycles to a 0.76\u00a0mm radius. Power factors above 1500 \u00b5W m<jats:sup>\u22121<\/jats:sup>K<jats:sup>\u22122<\/jats:sup> and a record\u2010low sheet resistance for flexible TEs of 0.4 \u03a9 sq<jats:sup>\u22121<\/jats:sup> are achieved, leading to unprecedented potential for power generation. This versatile fabrication route enables innovative implementations, such as cuttable arrays adapting to specific applications in\u00a0self\u2010powered sensing, and energy harvesting from unusual scenarios like human skin and curved hot surfaces.<\/jats:p>","DOI":"10.1002\/adma.202307945","type":"journal-article","created":{"date-parts":[[2023,12,15]],"date-time":"2023-12-15T13:39:37Z","timestamp":1702647577000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["Facile
