Pretty clever way of binding printed objects in the Z axis. Guess I need to lay off the Aggie jokes now…

Hello! Our community guidelines request that you add more content to your post. This is so we don’t become a link dumping ground.

I read the article and watched the video. interesting - thanks for the share - i suggest you edit as per @Justin_Nesselrotte 's request and add a summary statement to your post.

till then, for others, here’s the gist:

  • the add a layer of carbon nanotubes around the filament itself
  • carbon nanotubes are reactive to EM (e.g. microwaves)
  • when printing, the interface between layers has a high concentration of carbon nanotubes
  • they use specialty microwave sources to heat the printed part; this focuses the heat treatment on the interface between each layer
  • as a result they can (so far) improve layer bonding strength by ~2.75x
  • the intent is to enable a FDM printing solution for functional designs rather than just as fit-check prototypes in applications where strength is critical.

Good stuff but I need to see a good write up with it to keep it around!

@Griffin_Paquette , @Jared_Eldredge , @Justin_Nesselrotte … Should that also be done with any videos added?

6

It should be done with any post to this community at all if possible

@Rodger_Cooley yep! Check out the community guidelines for a good write up of what we are looking for. I like your content so far. Informative stuff.

I didn’t watch the video, but I skimmed the article. I wasn’t impressed with their apparent knowledge of 3D printing physics. I imagine that’s the fault of the journalist and not the experimenters, though. The site also changed 3D to 3-D everywhere, which is a good indication that they’re really out of touch with the field (and also probably have a style guide that hasn’t been updated since the 90’s).

Yo, @Rodger_Cooley , the Texas Tech mascot are the Red Raiders, not the Aggies. Nice to see the school in Lubbock doing good work.

@Nate_T , I know that, but this article is about the Department of Materials Science and Engineering at Texas A&M University

Dang, didn’t see the mention at the top of the article, I did see all the mentions of Tech, tho. My bad.

It’s all good. I’m an old UH Cougar, so not much to crow about… :wink:

I’m an SWT(!) Bobcat. I know the feeling.

I heard of zapping prints with carbon nanotubes in them for strength a few years back.
