Just a couple of pictures of some mathematical objects we have recently printed out to show you how support is crucial and what it looks like.
Seifert surface based on the Borromean rings: again from George Hart’s page. Printed in natural ABS on the replicator dual. The surface comes out very clean when the support structure is broken off, I will try painting one like the author did to show the intersecating rings (and if it does not come out nicely I have a backup!)
Calabi-Yau. Designed on Mathematica by professor Oliver Knill, mesh cleaned and corrected by Carlo Fonda. Again ABS on Replicator dual. The orange one stopped halfway probably because of a power failure. Serves as an example to show the support structure.
