At first with the kerning on my screen I was wondering why MIT had an Australian TLD.
They seem most interested in the thin band running through the lattice, my curiosity is how well can the 3D printer make that consistently? I would assume it's contribution to strength might be pretty significant, and might be quite non-linear with any variance.
A common frustration I've had with 3d printing is even keeping within specs on thin planes and walls can turn out suboptimally, but maybe thats some bike shedding, I'm ceratinly not doing anything in metal.
- rawfan 3y agoThose industrial titanium powder printers are not comparable at all what you know, I assume. They‘re used at scale to produce airplane parts. Usually also utilising bionic structures, e.g. to make brackets that are much lighter and sturdier, than their conventional counterparts.
- gimmeThaBeet 3y agoYeah most of what I do is in SLS, I don't really know what the nuances to how the sintered metal powder ones behave vs polyamide etc. One of the bits SLS can struggle with is long plane or ribbon-like objects. And then as you get thin enough, the surface finish starts being a non-trivial % of the overall thickness in that area. Just was curious how sensitive the strength is to uncertainty, and as a second part of the overall structure aids it by making ribs to mitigate any weirdness in the flat bit.
