Cutting edge 3d printing showcase.

OK, we are just amateurs.

Check some of this out:

If anyone has any other cutting edge 3d printing showcases, then please add. it's always good to know what 3d printing can achieve, and also give us inspiration and ideas.

Normal people believe that if it ain’t broke, don’t fix it. Engineers believe that if it ain’t broke, it doesn’t have enough features yet.

RE: Cutting edge 3d printing showcase.

It may not be as cutting edge, but I like what Lulzbot does with their Bio printer: it allows depositing either organic or growth support material in solid medium (jelly) which serves as a support. After that, jelly gets liquified by heat and poured away. I was immediately wandering whether similar principle could be used for more conventional 3D printing. It would require different approach, cooling instead of heating and some amount of chemistry.

But who am I kidding, if I think of such things, then Stratasys people do too and I bet they already have a patent for that.

A little liquid nitrogen, some water, a drip system to fill the part being printed, and viola!

RE: Cutting edge 3d printing showcase.

This may be a bit further from 3D printing, but this guy - Robert Liska of Technical University Wienna - has few papers in additive manufacturing technologies and polymerization research, and I bet portion of his research gets used in modern photopolymer manufacturing. This is an interesting one - for example UV-treated resin creates chain reaction of polymerization that spreads to remaining material (published 3 years ago) https://phys.org/news/2016-09-method-epoxy-resins-local-uv.html
