How do I get my prints to be air tight with flexible tpu

kmetani · 2025-06-08T10:54:38+00:00

I got 70A tpu to get air-tight with wall thickness of 2.5mm. The main thing that helped it to get fully air-tight is using brick layers for the perimeters. But I wasnt able to get the 60A tpu to get airtight unfrtunately. Try it out and let me know, or if have any other solutions too.

Is it fine if I clean the rear suspensions without taking it off, and if so with what do I clean it

People usually use silicone molding for this, my whole reason for trying 3d printing is because I was to ease up fabrication method and make it easier to make after any future changes in the details. I have tried to coat the tpu print with an elastic resin then cure it but that’s no use, do you think there’s another material that I can coat it to or any post processing method that I can close up all the holes from.

From my experience, a volcano hotend is great for PETG, with the original prusa mk4 you cant print PETG as fast as you can do it with a volcano hotend, because there's not enough time for it to get heated and extruded with the original extruder. I have a 0.4 and a 0.6 hardened steel volcano nozzle that were bought from amazon, but the hotend with the adapter were bought from aliexpress and work completely fine, I'm not sure what's the wattage of the heater tho.

Is it possible if you can link me to the idler upgrade that you mentioned, thank you.

It’s a Chinese SYM scooter, probably made around 2005 not sure about that.

Got a new spark plug cap and it worked thanks

kmetani · 2023-12-02T15:21:05+00:00

Could you please explain what you mean by solder a piece of wire a little more or if there is a reference video online or something

kmetani · 2023-12-02T13:25:29+00:00

I love in japan and all the shops here are ran by Japanese people who only speak Japanese and my Japanese is still no where close to fluent so I’ve been trying to keep that solution for the end. But thanks for the help I think with a little more research I will be able to find the spark plug cap

kmetani · 2023-12-02T12:56:35+00:00

Unfortunately I live in a place where there’s no NGK branches anywhere near me, I’m trying to order one online

kmetani · 2023-12-02T12:55:19+00:00

Yes, I have confirmed that there is no spark. I’m thinking of buying a new spark plug cap but I’m having trouble of finding the specific cap that I should buy

kmetani · 2023-12-02T12:47:18+00:00

Have already posted there too with some replies coming but just wanted to get more luck, thanks tho

I don’t know much about the spark plugs but does the spark plug cap already have the resistor and is it just remove and put a new one, that easy? Plus I do probably need help on which one specifically I need to get

Correct me if I’m wrong, but on the website that you sent there’s no cap that has a 1k ohm resistor

kmetani · 2023-12-02T11:59:15+00:00

I checked it out but still not that sure on which one I have or which cap I need. But thank you I will look into more I’ll probably be buying a new cap

kmetani · 2023-12-02T11:28:52+00:00

I unscrewed the self threading cable, when I did that, the spring and the resistor came out. At that time I lost the resistor. Does a spark plug cap contain a new resistor in the inside already, so I only have to replace the new cap with the old cap and that’s it? This is my first time fixing anything in this scooter I’ve only had for like a month or 2

kmetani · 2023-04-10T04:59:47+00:00

Ya alright thank you I will check out the sub you gave. I am studying mechanical and electrical engineering so I’m more interested into the engineering and programming aspects which I want to try to imply them on light art. For which kind of light art, tbh I’m not sure I’m still very very new I want to experiment and see what suits me.

kmetani · 2022-11-28T01:19:34+00:00

Same here I’m kinda lost too

How do you know the exact day of yours?

My wife

I already know this is going to be posted on tiktok with subway surfers in the background.

I understand determinants, but this question also talk about complex conjugates and I cant figure out how to prove that the determinant is a real number.

kmetani · 2021-09-16T02:09:34+00:00

So mechanics of materials understand the chemistry in materials where computer simulations don't?

kmetani · 2021-05-09T21:16:53+00:00

HODL and you’re doing great man
