MetricUSA Posted March 20, 2023 Share Posted March 20, 2023 Ugh. I need some type of flexible foam to fill in the seat!!! I bought this seat on etsy from eucpip... Do not buy soft version of seat no support what so ever!!! And seller/maker is not helpful either... You can pinch you skin sitting on the damn thing... 2 Quote Link to comment Share on other sites More sharing options...
chanman Posted March 20, 2023 Share Posted March 20, 2023 (edited) Looks like a tpu print with no/very low infill? It's tricky because the material itself is hard so it needs the give to feel soft, and significant infill makes it very stiff quickly. Been trying to make something like that doesn't suck myself. Yeah you could try making a hole in it and fill with expanding foam or something Edited March 20, 2023 by chanman Quote Link to comment Share on other sites More sharing options...
Popular Post Cerbera Posted March 20, 2023 Popular Post Share Posted March 20, 2023 (edited) I really don't think 3D printing is the way to go for seats. Not only does it look a bit 'amateur hour' but we're trying to force a square peg into a round hole there, by using a material that is intrinsically hard in a way that makes it structurally weak, in the pursuit of 'softness'. What we actually need is something with a structurally solid base, and a thick but firm foam pad on top of that, ideally covered in soft leather or vinyl equivalent. You can buy moped seat pads that are exactly that, and can be velcro'ed or strapped on to EUCs effectively so I would do that rather than pursue the TPU / printed options. Or buy your own blocks of dense foam, vinyl wrap and base materials and make something yourself, which could be an interesting project if you like that kind of thing ?

MetricUSA Posted March 20, 2023 Author Share Posted March 20, 2023 I don't have a company in my city that make foam products I could call up, and can foam will just break down...need a heavyduty balloon... Quote Link to comment Share on other sites More sharing options...
Tawpie Posted March 20, 2023 Share Posted March 20, 2023 you could always ruin it by (quickly) adding some of this stuff! https://douglasandsturgess.com/products/flex-foam-it-v-trial-set Quote Link to comment Share on other sites More sharing options...
EUC Custom Power-Pads Posted March 20, 2023 Share Posted March 20, 2023 For this very reason, I'm in the process of making a seat for the S18 that has a base of hard plastic and then gets a soft printed pad of TPU on top. If it doesn't work with TPU, I'll put 4cm of EPDM foam on top, which will then unfortunately require extensive manual work again. Quote Link to comment Share on other sites More sharing options...
supercurio Posted March 20, 2023 Share Posted March 20, 2023 (edited) It is possible to make a good 3D printed seat @MetricUSA but the one you show is poorly implemented indeed. It's not acceptable and I hope you will get a refund. This one can't work correctly, here's why: Has vertical walls Perimeters vs infill ratio is too high. If perimeters are not as flexible or elastic as the infill the whole part will crumple and collapse in undesirable ways like you showed Too high for its dimensions Too soft Total fail, must be redesigned and slicing be highly optimized during printing. It also means that printing will be slower, so the seller might not want that. Edited March 20, 2023 by supercurio Quote Link to comment Share on other sites More sharing options...
Funky Posted March 20, 2023 Share Posted March 20, 2023 (edited) That isn't a seat.. That's a washing sponge... Google: Yoga block. Quick, easy way to make your own seat. Form and size is already perfect. Put some "softer" filling/layer on top of it. And then rap it with fake leather or something. Your imaginations is the only limitation. (Pretty easy to cut the cork block.) Edited March 20, 2023 by Funky Quote Link to comment Share on other sites More sharing options...
Funky Posted March 20, 2023 Share Posted March 20, 2023 Good example made by @Raptor Looks perfect even without the rap or anything.

MetricUSA Posted March 26, 2023 Author Share Posted March 26, 2023 (edited) Thanks I was thinking of flexible mix, but it is too finnegie and you have to get the mix just right... And too expensive... How about a water and cornstarch OOBLECK SEAT!?! Might be too heavy and a hard bounce 😂 The 'cushion' is too tall for me on my s22 when standing on the ground and straddling it, it is actually too hard to push off with the seat on...I think I gong to reduce height and split it roughly in half add firm packaging foam sheats, then sliding the top half down overlapping bottom. I have a soldering air heat pencil to heat and melt the two halves together... Frankenstein style...

Cyph Posted April 17, 2023 Share Posted April 17, 2023 I just made a T4 3D printed seats that work really well. I used a PLA base and then the top is TPU infill. Had no issue with it getting squashed. Quote Link to comment Share on other sites More sharing options...

I really just need the base part so I don't accidently hit the button on the trolley handle of my KS16x and then I can put on a more comfortable seat from there! I just was discussing this at the library omw to work today. My jump pads should be done by friday hopefully. But then I got to thinking, "If I can print jump pads, why can't I print a seat?" then was disappointed when I searched because no one has a design for them.

pictsidhe Posted June 8, 2023 Share Posted June 8, 2023 Never made an EUC seat, but I have made motorcycle seats with camping mats and a carving knife. 1 Quote Link to comment Share on other sites More sharing options...
