That was an interesting video, thank you. Two things I'd do different are, 1, cut the mixing stick flat to be able to get into the corners of the cup (round doesn't "scrape" the resin from the corners} and 2, use gloves all the time because no matter how clean your hands are they still have body oil on then and it could affect the paint/primer you put down (unless you use wax and grease remover before priming/painting). Thank you again for your time and video.

Hey Andy! Mixing stick makes total sense thank you. As far as the gloves, I 100% put them on once I am ready to paint/primer. I normally work bare hands but once I am ready to apply something that needs a clean surface I throw some gloves on and then Clean/Paint. I learned the hard way how important this is lol.

Can’t wait to see the carbon part! Great job so far 👍🏻

Try uv resin thats used in 3d printers, you can add multiple layers quickly just curing with uv lamp between coats😉

Hi, the video is very explanatory, I will try to learn the method to apply it to some mold.

one option to smooth it out that may be worth trying is acetone smoothing. Basically exposing the plastic to acetone vapors and it reacts with the plastic to create a very smooth surface

@@mike230224 sadly doesnt work with petg. But I am also not worried about the smoothing as i am about the mold being air tight which is why coating with resin is so critical. Otherwise air gets thru the filament during infusion.

It was a shame you didn’t show the finished products, like you had on your cover photo. Looking forward to seeing them created.

I use epoxy gelcoat to fill in the layer lines. Prefect to get a smooth mirror like finish.

Can you share the brand/name you use? Would love to look into this as well. I am by no means doing it the "right" way, just a way thats been finally not leaving me pissed with infusion lol

@@poltdesigns i use R&G. It's a german company i believe. And most of their epoxy products are aviation approved. I'm not saying u are doing it wrong. I just like the gel coat a bit more cause it's a little thicker like sirup.

@@TheTechnoaddict 100% agree. I might have to try a mold with your method. I do have Gelcoat laying around but its not epoxy lol.

Working with resin and sanding inside, you really should wear a mask

@artrozenbaum2367 3 ай бұрын

Looks nice. If you were to use a gel coat or tooling resin instead of the one you used, would you be able to get away without using the primer?

@poltdesigns 3 ай бұрын

I honestly do not know. I tried to uuse tooling gelcoat on a test part and wasn't confident to use it on a real part. The primer is also very very easy to sand which is why I use it. And I have a gun for it so its easy to apply even as well as clean the gun after.

Have you tried using a body filler then sanding before you resin coat it?

@poltdesigns 2 ай бұрын

@@webreakforsquirrel4201 so I actually do use the putty or filler if I have dramatic gaps or serious issues with prints. But if its to use it for removing layer lines than nah because by the time I add my primer layer all the lines are gone. They actually are gone after about 2nd stage of resin for me.

Would a kitchen oven from Amazon work well as a shop oven, or is it better to DIY an oven for use? I'm only building for myself with carbon fiber in two categories: ultralight hiking gear and electric longboard gear. I'm in the process of building a carbon trailer to be pulled by my electric longboard. Any help would be greatly appreciated.

@poltdesigns 2 ай бұрын

I think a kitchen oven would work just fine. Its all about curing the resin. You can also just cure it at room temperature it will just take longer. Hope this helps.

@mahanghorbani523 4 күн бұрын

Does that mean that if I leave it at room temperature, it will cure enough to reach a temperature resistance of 150⁰c? Because after just the molding process, carbon fiber composite heat resistance is around 80 to 100⁰c.
