Hi, i would like to print a piece of plastic, it should be strong but the top piece should be bendable so when you press on it with 150 pound, it goes up and down like a spring… i am in New York please advice

70kg sounds quite heavy for something 3d-printed. What kind of dimensions are we talking here? My gut feeling tells me, that printing something like this in one piece is not a good idea, because the shallow overhang will not be as strong as it could be. so having the bottom piece with an angled side and then a straight plate secured to it with screws sounds safer.

Does it have to be plastic? How big is it and how much do you want the top piece to move?

You need flexible nylon plastic as your material. Don’t have that and can’t print it with my machine. Good luck!

Maurice, Sounds like this would need to be 2 pieces. Putting 150 pounds on plastic that is suppose to be elastic would be complex depending on the the material and how the force is applied.
Yup. I agree with the other guys. 150lb is just too much for a 3D printed part. Hard to tell how big this thingie is but if it’s printable on a standard machine it’ll just be too weak. You could use a small piece of 4mm carbon fibre as the springing element and set it between two printed parts. Maybe that would be the best option.

Hi, we can print the piece with ABS plastic, which is strong and make the top piece in specific thickness that will respond to the weight pressure. Give me specs and I will work on it. Thanks, Iury
To make the part bendable use ninja flex in the model and reinforce the top and sides with ninja flex. This will make it so your part can bend but not break.

This really depends on how big the part is, how thick the overhang is, and the material. Without knowing the first two I would simply suggest nylon material. Nylon is flexible enough to be able to bend but not like Ninjaflex where it is elastic. The impression I get is that you want a rigid yet bendable part and nylon is best for this. ABS won’t be flexible enough for the spring motion, it might bend but wont bend back. PLA will just break. Someone suggested having a little bit of kevlar but I’m not sure that would be flexible enough. As for not breaking under 150lbs, you may have to increase the thickness of the part that you want to bend. It would be great for us to know the dimensions of everything to better help you. Also if there is any way you can post a link to the file, I might be able to help with stress analysis via Solidworks. We really need overall size dimensions and thickness of the overhang though to give the best advice.
To be able to run a Detailed Analysis More Shooting diagnosis without printing at random must Have Exact measurements thing devel Serve this release and the necessary data on the size of the piece , thickness to be printed , having all the data you can Evaluate Possible Solution with All That Materials wE possimo price of everything and the whole thing if we can rate it as the data supplied are too few of the price for a hypothesis of all kinds.
thanks
