3D Printed Lattices Replace Foam for Customized Helmet Padding | The Cool Parts Show #62

I could see this technology revolutionizing the mattress industry.

[@Veldtian1]

The 100% #1 application for this is highly breathable full head coverage infantryman ballistic helmet designs.

[@UrSoMeanBoss]

that opening was great lol and so is the tech

[@A_Tempest]

I would disagree with 'foam being the material' foam is also the structure giving mechanical properties to the material, it's also a lattice just in a more organic and less customisable shape. A block of polyurethane does not have the same properties as polyurethane foam.

[@raulkaap]

"Foam" is a microstructure. This stuff is a macrostructure. I think there is a fundamental difference. Or is it semantics?

[@0Logan05]

.. Simple, Made a few sets on my CR10 for my Mich helmet a few Years Ago.. Just Made another set for my Brothers Air-soft Kit….
Everyone with a Printer and Slicer can make them for $5 in TPU and a few hrs to print.. The Measurements are very Forgiving.. DIY..

Nice 🎉

Did these two helmets pass the respective impact testing standards?

[@generallattice]

Great question! The helmets worn by Peter and Stephanie are just concepts that have not been tested as a complete assembly, however, the Digital Materials used in them are based on relevant research conducted by General Lattice for the US Army DEVCOM SC.

[@user-lo1mx6ow1j]

Sadly our military helmets have some of the worst impact protection in the helmet category. Good at stopping bullets, not so much for a blunt force impact. Would be interested to see how these two helmets performed in their respective standards. @@generallattice

[@aarontarr613]

Will this custom 3D printed lattice structure add-on to helmets be used in professional sports such as the MLB, NFL or Racing?

[@Veldtian1]

If the team management are smart and pursue it it will.

[@user-on2hb8tk6o]

!!! Super!!!

Rhino Grasshopper! Sweeeet =)

Materials do have material properties, which can be exploted through geometry. A thin sheet metal part with stiffening ribs can be much stronger than without those ribs. This does not mean that the material properties change or vanish. This is also nothing new, every part is designed that way (look at my sheet metal example).
There are no "digital materials" there are materials and geometries. What they do is they exploit the hollowness of those parts nothing more. You can do that with any FEM software and analyse the behavior.

[@outdoorflowsports]

Exactly.

[@markmichael17]

Why do they look like scrub daddies. Let's try using it to wash our dishes. Might turn out cool.

[@AdditiveManufacturing]

Let us know how it goes!
More seriously, the lattice padding is comfortable and does NOT feel like a SD.

[@DingoAteMeBaby]

Why would that be better than foam for helmets? Who cares if its custom if its a compliant material? Seems to a greater degree a technology looking for a purpose.
Best use case I can imagine is a military grade fanless server inside a pelican case, where passive airflow and cushion is important but cleaning is not required (IE no dust). At that point tho you might as well use thermal bridging of the case/heatsink to the outside of the pelican case.

[@supremecommander2398]

it looks like it could be lighter and much "cooler" then regular foam. so for someone having to wear a helmet over a long time, the open lattice pads could pose a significant improvement . Personally, i would try it as a foam replacement in car seats for the very same reason

[@DingoAteMeBaby]

@@supremecommander2398 Looks more cooling. I just don't see it justifying the cost over foam at scale, except in niche applications (aftermarket helmet inserts, aftermarket plate carrier pontoons)

[@sierraecho884]

@@supremecommander2398 Foams can be also designed that way, they are just way way way cheaper.

[@sierraecho884]

There are many many cases where 3D printing is way better than conventional processes. Engines, turbines, cooling applications, super light and stiff parts etc.

[@Michallote]

@@DingoAteMeBaby objectively speaking most emerging technologies seem unfit or absurd for modern times (jet engine turbines were dismissed at first as they were 'simply not worth it'...). However those who are able to see the fitness of their product sometimes make it work. What you are not able to appreciate is that they have technology that allows them to create any lattice to spec and then 3D print it. That algorithm is worth something

[@HardHeadVeterans]

Hey guys, loved the video! If you are curious how Micro Lattice Pads are already being implemented in ballistic helmets you can check out a video here. ruclips.net/video/GYkDmUJenHk/видео.html

[@LAZARUSL0NG]

Wow. Everyone really said “digital material” a LOT.
What an unpleasant marketing nonsense term.
I hope I never hear it again.
At first, I thought that ‘general latice’ was a startup setting out to produce 3D printed custom latices.
Sounds a little like the 3D printing 2023 equivalent of a 1990 startup boasting: “Send us your hard drive, tell us what files you want put on to this newly invented “thumb-drive”, and we’ll copy them over for you onto a drive that will fit right in your pocket!”
But apparently, it’s not even that good.
They’re building a database of latices…
So, it’s like a startup in the 1990s looking to provide a library of open source “file types” for the particular use of any companies that might pop into existence offering professional file-transfer-to-thumb-drive services.
Sell your company for as much as you can, as soon as possible, to someone who doesn’t understand what they’re buying.

[@olampros321]

You don’t have idea what you’re talking about. Foam is not a material is a geometry. At least spend 5 minutes in research before you make a video.
