Flexible Armour

I have finished my first piece of flexible armour, I have casted this piece using the forearm from the old set of armour as that had a good fit.

After it was casted I used Flexi foam 15 as the main material, the painting did have some back and forth but it’s the same process as what I do on my normal 3D prints which is good.

I am making this suit more dusty and dirt and I think it makes the pieces look a bit more realistic with all the dirt, it’s probably a bit too much but I love the look.

Help me learn from my first failure.

Hello!

Looking to see what I am able to learn from the community here about my first failure.

I am trying to 3D print my first set of armor on an Ender 3 V1. I have been watching tutorials and have been in Armorsmith getting my scaling set.

Long story short, I got a few thermal runaway errors and the print became miss aligned. After trying to resolve the error and I had to cut my losses at 82% completion.

I am using MoeSizzlac Halo Infinite 3D files and wanted to get some help on that I have learned so far.

- Is there too much thickness between the inner and outer walls? The print file in the picture was about a 2 day print with supports.

- Are there any recommended setting for printing or should the defaults mostly work? I have gathered a bunch of settings from tutorials but I assume there are too many differences to have an overall recommendation?

- Regarding scale in armorsmith, I plugged in my measurements but I feel that there is too much room in this piece. I know that I can fill in some and the under suit will take up some of the space. Thoughts?

Thanks everyone. I am finally trying to make the thing that I have wanted since I was young and the amount of things to consider can get overwhelming.

My take on the K variant of the Ma40. I am using this for my UNSC Ranger coatume for SDCC this year. Been a ton of work, cant wait to take the whole fit out in public. Ironic... doing a Warhammer 40k kit the next day. 40k Friday amd Saturday 🤣

Old vs New Galactic Armory ODST visors

85 Upvotes

Just received Galactic Armory’s new ODST visor. It’s a significant improvement on their old one. I previously used their clear, vacuum formed visor for my original helmet (right) which I airbrushed silver, and built a second helmet in anticipation for the arrival of their new injection-molded visor.

The difference is even more drastic in person.

Has anyone printed the Galactic Armory Mark V armor without changing the scaling?

5 Upvotes

I bought the model and have been working on it and was just curious if anyone else here has printed it and if they changed the scaling at all, I'm 6'1 but some of the measurements still seem long (such as the thighs) and was wondering how the armor was working for them, how they handle mobility with thighs and the shoulders and whatnot, and if you have any tips or videos or something to help, it would be much appreciated.

So far I've only printed the helmet and am working on printing the torso. Only cosplay experience I have was printing the Berserker armor from berserk.

This is the new ‘Dutch’ variant up-armoured helmet from Galactic Armory with one of their new pro-grade visors. My cat had to get involved.

Decided to go with some sort of tiger stripe ish style. The pro visor from galactic armory is so good! The visibility is amazing. Need to add some more detailing and weathering but the color scheme is starting to look sick.

Gotta make a kit to go with the pro visor I bought I guess

Thinking about doing a rakshasa/odst hybrid build. I’ve been looking at all the different designers for everything. Which ones do yall like and why? I’m leaning towards brink or skookum but I cant find pictures of skookum kits.
