The PLA version made more sense. The point of the corner is close to the surface of the print either way, but since the TPU gives way, the point loading in any collision is still going to be higher than with a rigid material.

[@MDalton10]

No way. Tpu is air tight each pocket of air inside of the infill acts as a cushion.

[@daliasprints9798]

@@MDalton10 It's air tight if you print it right, which clearly wasn't the case here from the bad overhangs and stringing. Probably running with no linear advance/pressure advance. Maybe also under extruded.

the tpu version is worse though? instead of making the corner less sharp, the corner just punches through the tpu and into the melon

@@Misha-dr9rh I think they meant moving the mattress away from corners.

[@HaleyPBear]

[@cowcannon8883]

I think for this a composite material makes sense. A hard outer shell that is built to crack and shatter sending that kinetic energy into breaking or sending it flying with a tpu underneath to absorb the rest of the impact. This is what i did for my phone case.

[@abdexa]

You made it worse. Material now flexes in to the corner on impact and exposes sharp edge through the material.

[@P4TRICCS]

It was pretty visible and i think he know that. This is why he printed with pla in the first place

[@Oberonjames]

Is it possible that flattening the surface exactly opposite the corner would be better? As in, it would give the impacting body more surface area to dissipate the impact?

[@hellothere6627]

The TPU wouldn’t have flexed that much, there was enough room and enough infill that the corner wouldn’t be felt

[@jacobc9221]

Maybe it shoyld be a PLA inside and a TPU outer layer that fits onto the PLA. That way, it's a cushion that spreads the impact out with the rounded corner.

Regarding design: I made mine out of PLA with one perimeter line and not much infill. So it has a bit of absorber/crash zone. Regarding kids: my daughter putted a blanket over her head and started running through the house. I catched get several times before crashing into the brick wall. Once she did it again, I saw it and let her crash into the open, flexing door panel. Intentionally. Some kids have to learn through (painful) experience. I told her not to take small toys parts into the bathing tube. She had to loose them before she realized it's better to listen to daddy. I love her

[@straphyr]

My sister had not great coordination as a kid and also enjoyed running around with a blanket over her head. Until she slipped in the hallway and got some scratches and bruises down her face from the drywall. For some reason she never did that again.

[@wolffang489]

Testing the single-use shock absorbency of a flexible filament vs absorbing the energy with a brittle plastic could actually be really interesting. Maybe the answer is actually a multi-material solution like some phone cases.

TPU I use different infill patterns to get different softness of parts but string is rarely an issue with the right retraction settings.

What about hard pla shell like your original design with adsorbing tpu pads underneath. Bit like a bike helmet :) Although agree moving the mat is the best solution

[@DonPochoZ]

That actually sounds great

[@hellothere6627]

This can be done by increasing the wall thickness from 2 lines to 4 or more lines. TPU is very versatile in how soft or hard it can be made, it just takes some experience to understand how to manipulate it the right way

One time when my sister was little she was running through my grandpas shop and hit her head on the corner of the work table. She had to get stitches above her eye because of that. So grandpa cut of the corner to be rounded and wrote "[sisters name] corner" on it along with the date lol

[@cameronlane3567]

It would be kind of cool to print it in glow in the dark or make it glow in the dark so at night you don't slam into the corners and you will also see some of the shape of the furniture to avoid it

[@TheDeepDiveLLC]

It's easier to prevent a child from injury by getting rid of the factor itself... the bouncy mattress, the table and/or the child.

[@marksmithwas12]

I don't know if this was common everywhere, but when I was in school, all the tables had a rubber rim all around the edge that effectively made the corners rounded

[@zer0fukz790]

this is me putting in work to make a solution because i feel super smart doing it but then I'm like screw it just do the easy way

[@TYsdrawkcaB]

A lot of people are saying that "the TPU gives way and exposes the sharp edges" (paraphrased from a couple of comments), so I have an idea: you have the original PLA corner protector and a TPU layer ON TOP so that the TPU layer still absorbs some impact by flexing, but if it gives way and exposes what's underneath it, it's not a sharp head-splitting corner that the head is hitting but rather a rounded corner protector.

[@seanpchristy]

Tpu just crumpled into the point i guess need something like a reverse phone case. Pla to round out the hard point and tpu to add a crumble zone. DUAL material let's go!

[@DaQuackin]

Me the whole video: just move the mattress

[@kalibradley6661]

I'd suggest moving it near a couch or a well cushioned chair that way she has a chance of hitting the soft things and not the floor

[@graphi1477]

Yeah I was about to say that plastic is also ry hard and that tiny rounded bit could act just as sharp

[@Mellence]

This just sent me flashbacks to when my son fell from our cat tower (which he was not supposed to be climbing on in the first place…) and split open his head on the corner of our cube organizer. Luckily it was just a big scrape that took 3 staples and the champ was more worried about possibly cutting his hair vs. the pain from the scrape

[@thicccrusade2302]

Ah yes, the Pre-traumatic stress disorder. I have that too in some cases.

[@CircsC]

I think continuing testing until a design works would be neat to see how far you'd have to go. I'd have the most hope for a multi-layered design with compliance/crumple zones. TPU-PLA-TPU with voids to absorb energy.

[@hellothere6627]

TPU alone can create the multi layer crumple zone, TPU can quickly and easily in thin parts be made extremely soft to rock hard and the designer has complete control over the entire spectrum

[@padmanabhaprasannasimha5385]

You need to use retraction with your tpu print settings. It really works.

[@daliasprints9798]

Yeah this print was clearly on a setup not suitable to TPU at all. Likely missing LA/PA. Not sure if retraction was off too but it might have been. The print was an utter stringy mess with wrong material in some places, missing material in others.

[@vial7305]

Also put some carpet to soften the fall if they do fall

About 10 years ago, I dated a girl and her dad came home dizzy from working on a roof one summer day, he was standing in his kitchen, passed out and hit is head on a table corner, and later died. My first time meeting him was at his funeral. :( It's nice to see you making a design to address this.

[@billallen6109]

Lost in tech might be able help you with that stringing. He's done some in depth work with tpu

For ur piece, try using less infill to give it more room to squish down, may work

[@stevenv9205]

try designing a large plate like stopper, something that gives it more surface area

[@mcrsrm]

Umm... yeah. Move the mat. My girlfriend just moved the sofa against the wall (which half blocks a bedroom door and the kitchen doorway, which was why I had it about 2ft away from the wall) I told her we couldn't keep it there, because one of us would break our toes. She says to just be careful. 3 days later, I had the dishwasher open and collecting all the cups around the house (the dishwasher half blocks the kitchen doorway on the OTHER side) and on my way back to the kitchen. And while I didn't BREAK my toe, it WAS sprained, and the first 3 days I THOUGHT it was broken. But as soon as I stood up from cursing on the floor, the sofa got moved back.
