3D-Printed Door Handle With No Moving Parts

First argument with the wife, handle ripped off. Door slam, handle latch ripped out. And wait until the kids get a hold of it.

Clever but impractical idea. Maybe for a bird feeder door?
 
I don't think this would actually hold the door shut against a stiff breeze...
 
I assume the point is not the door handle itself, as the current form of door handles works just fine, but as a simple example of mechanical systems produced of a single piece via 3D printing. It's not that thrilling, but the point is to fire the imagination and show the system in action. If my guess is correct, the more practical use for this is all kinds of simple machines that would be used in larger systems.
 
I imagine if you were going to use it as a handle, it wouldn't be for your front door. It would be for the cabinets in your cheap travel trailer, and it would melt shut the first time you took it out into the desert.
 
When they said meta materials, I was thinking I would be shown something novel, or a new technology - this is is not newsworthy, or if it is, please let me know how.

This looks like it is much more likely to break over a "moving parts" system.

I don't even see the value of this, is this even an unknown system? It seems basic and simple, and not something that had not been considered before
 
It's interesting because it's a (3D printed) compliant mechanism, just like a few others things in your house that you never really think about. Some other examples include: shampoo bottle lids, plastic tweezers, or a pair of vice grips.

Yep. This sort of crap is annoying. Just hipster douche bags trying to look cool. Wouldn't last. Just like bending a bit of copper back and forwards... this shit will just yield in short order.

Sure its cool and all. But thats all it is. Just more click bait rubbish for the pathetic excuse that is the main stream media.
 
The Jurassic Park quote is appropriate again.

The concept is nothing new
It looks ugly as fuck
It's not well designed, it's wobbly and probably weird to touch.
It doesn't really latch the door, as likely a toddler or a pet could force that shit open without touching the handle.

So what's the point? Get rid of it!
 
I could see this being used with children toys like playhouses. I wonder if they used dissimilar materials in the design could the latch be activated/deactivated by environmental factors like temperature or humidity. It could then be used with some sort of switch. I find this interesting.
 
It couldn't even return to the original position it was in before he used it the one time. Lack of durability is an understatement.
 
Actually I think it's interesting, not useful as a door handle, but it mimics how our muscles work, and if we can print muscle-like contractions easily those might be useful in situations like within our bodies, submerged in water/oil, in places where one needs to squeeze the device through something else and have it expand into place... I dunno... just trying to be positive here, it's not a total waste of effort, like others have said it's purposefully experimental which may spur on more useful applications...
 
You have to wonder how resistant this is to the impatient pull. I'm going to make an unsubstantiated claim and say most of the abuse on door handles now comes from pulling before the mechanism is clear.
 
What happens when the material becomes brittle over time? Losing its elasticity or outright cracking?
 
Oh look apple invented a 'better' door handle!!!!

Seriously though....that wouldn't hold up against jack. I mean its a col proof of concept and all and its functional.....but half that stuff I would rather use real parts and real metal.

A door handle that can scream RAPE!

The future is horrible. I'm staying here.
 
I understand that the door handle is just an example, easy so every one can understand the concept and relate to our every day lives. I think this has potential especially on recyclable products like porta-potties. How about usage in application that require super quiet operation like a sound studio or zero static discharge or zero spark. Think of situations where mechanical function is required but the hazard of metallic or hard plastic would be injurious like a fleshlite or medical devices.

No it may not last forever but sometimes things just need to get the job done and recycled.

Go and use a shovel for an hour with any kind of vigor, and let me know how your self-healing biological hands come out of it. ;)
