The Dark Knight suit (3d printed) - help

[jumpman971]

Hi, i've been 3d printing a TDK suit for like 5 months (but not every day).
Here's what i have 3d printed so far(Bust, abs and sides):

Some pieces might need to be reprinted but that's not a problem.
The problem is that i'm trying to begin the polishing process on the chest, only trying because i'm having a really hard time making this step (the paint job is wet on those pictures):


I've watch tutorials on youtube. The one that i've tried is using sand paper and paint can:
The process is sanding the object, painting it, sanding again on the paint and painting it and doing this again and again, till the thing is smooth.
It's a too long process and it's not even a success with me.
There's another process with acetone and a spray: it's vaporising acetone on my 3d printed objects but this process seems a little bit too "random" to me.
So i'm here to ask for some help. If anyone have a great solution for me. It would be greate cause i really don't know what to do (i've a few raws idea but it's kind of risky ideas).
Thanks in advance.

Are you using filler primer? It makes a huge difference.

 

[jumpman971]

i actually don't even know what it is lol but i'm googleing the thing right know.
EDIT:
hmmmm i'm having a hard time finding filler primer that is shipped in france (it's where i live).
There might be this one: https://www.la-becanerie.com/extras/peinture/apprets/bombe-primer-appret.html but i'm not sure if it's like the one that you use. I'll try to get one in a market.

Try XTC 3D from Smooth On.

And maybe give theses guides a read before you go much further -

Ok so i've bought one filler can in the market and here's the result (paint job is wet):

It looks definetly better in less time than what i've been doing before. Still, my chest needs more layer of this filler can. @GasmanR thanks for the advice. I saw the XTC 3D before and i asked a guy about it and he told me that it was useless with the quality of objects printed with i3 prusa like printer. Well i'm starting to think that i should definetly try to buy one XTC 3D someday. And thanks for the links, they look really usefull.

EDIT:
here's a little update on my work:


Some imperfection are still persisting. Gonna have to sand them.
Anyway, thanks for the help again everyone.

You can try stuff from auto repair shops, like Norauto in France I think it's called. They have this filler putty for bumbers and such, sold in tube. It's fairly easy to apply, and sands really well. They also have filler primer in spray can. For best results, I found that you need to sand the piece first with a rough grit, use the primer putty, sand and repeat until smooth, then a few coats of the filler primer, with fine grit sanding in between, before the color coat.
To be clear, it's not the stuff you have to mix, it's really a tube, like a toothpaste tube.

Plan B is woodfiller from any DIY store. Sands really easily, but I find it a bit harder to paint as it kinda drinks the paint. So you need a very good base coat of paint, probably several layers with light sanding in between.

yes, i got my primer can in norauto. And thanks for the advise. Im gonna try what you are saying.

Did you make your print files? If not, where did you get them from? This is one I've been thinking of doing for a while.

@harmfulAdam
for now, what i have is printable at ~70%: you can find the upperside of the suit on thingverse but it's not sliced (So i had to sliced it myself), the bottomside (the pants pieces), the arms and the neck come from a pepakura file that i'm making printable (the pants is printable at 80%, the arms are printable but need to be sliced and the neck is printable at 40%). I might release what i did when i'm finish but i think i'll have to ask the autors of the original models that i'm using first.

By the way, i had a question:
Some part of the suit needs to be painted in a carbon mesh looking like on this picture:

Here's a video that explain how i can do that with a grey spray can and some kind of mesh or texture (i dont know the exact word for this) :

The problem is that i don't know where i can find that mesh. Can anyone help me find one plz?
Also, i'm starting to think about the undersuit that i'm gonna have to use for my suit.
The biggest problem is the hexmesh that needs to be on the entire undersuit.
I've found this t-shirt (don't ask me how lol) that have a hexmesh looking:
https://fr.aliexpress.com/store/pro...shirt-V-Neck-Singlet/2227072_32793212629.html
I think it's a pretty good start but i would like to hear if anyone have better ideas.

EDIT:
never mind for the carbon mesh like, i just really need to learn to read (the answer to my question was in the video description).
