Michael Hjembæk 🇩🇰I am working on a new prototype. I have drawn this 3d model of a "Double Interpenetrating Tetrahedron with a surface of triangles in a Sierpinski pattern". It is a challenging 3d print with thin narrow sides and overhangs. Printed in PLA with Revo Six Nozzle 0.4 @ 0.2mm layer height with organic supports. <a href="https://pixelfed.social/discover/tags/3dprinting?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#3dprinting</a> <a href="https://pixelfed.social/discover/tags/prototype?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#prototype</a> <a href="https://pixelfed.social/discover/tags/tetrahedron?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#tetrahedron</a> <a href="https://pixelfed.social/discover/tags/sierpinski?src=hash" class="u-url hashtag" rel="nofollow noopener" target="_blank">#sierpinski</a>

Michael GebisPrinting Nat(a Cyborg)'s Sierpinski pyramid, and hot damn is this a badass looking model or what?Even cooler, each layer is a continuous curve, so this is printing in spiral vase mode. Neat!I'm printing using a 0.6mm nozzle, using the 0.15 layer height "Finn" version, in dual color PLA.

Die Frage ist, ob 78557 wirklich die kleinste Sierpiński-Zahl ist oder ob es noch kleiner geht. <a href="https://www.heise.de/hintergrund/Zahlen-bitte-78-557-geht-s-noch-kleiner-7396985.html" rel="nofollow noopener" target="_blank">Zahlen, bitte! 78.557 – geht’s noch kleiner?</a>
