Starting my ODST build

[chaos cre8ions]

There are plenty on these forums... Whats up?

I picked it up last night, and want to make sure I'm not going to mess up the rest of the armor as I print it

Sorry I meant for the Visor material when you vacuum form it. The transparent sheets of PETG. I printed my buck out of PLA on 25% infill and it was more than sturdy enough.

100% right about the visor material, but the bucks you usually want to print out of PETG for heat resistance and up the wall count to at least 5 walls. 25% infill is good too

I didn't mess with the infill. When I break this buck I will up the infill. I'm glad to see the gut hunch to make it out of PETG was a good call.

Honestly the wall thickness is going to be more important. You might still be fine. You can always try it out then up the strength on the next try like you said!

The first attempts went ok. The buck survived, but the shopvac was too weak. Rip

Hey, at least the buck survived and you can use it again! Were there any air gaps in the vacuum former you made or is it definitely the vacuum?

Does your frame pull down past the vacuum plate or just flush? I had bad pulls until I modified mine to go a little past the vacuum plate to insure a good seal.

It pulled past, but you couldn't feel any suction. I've since upgraded and revamped my build box.... Tomorrow morning I will run attempt number two.

I used calk to fill the gaps to make the seal. That's what I get for cutting corners.

Calk was what I was going to suggest. That's actually really good for filling air gaps.

 

[chaos cre8ions]

I calked the inside as well.

 

[chaos cre8ions]

The new setup! Suction is noticeably better.

I got it to form to the buck. Unfortunately, it exploded when I tried to remove the buck from the plastic. Am I using the wrong plastic? Did I let it cool for too long?
Here is the link to the plastic I used: Amazon.com

You probably want to try PETG, it will be more flexible than acrylic.

*Edit: I'm an idoit... This was the wrong material. That explains the explosions. Off to round 3

That's exactly my issue

Don’t beat yourself up about it. We’re all learning here. I also tried acrylic at first, then transparent film, then bought the wrong PET sheet, and even set fire to a toaster oven trying to get it. You’re doing great.

Have you tried using a Dremel to remove the buck on Acrylic? That may be a future attempt. The Acrylic formed beautifully, but was too brittle when it came to removing the buck.
Also, How did the toaster catch fire?

Love the way this is looking dude, keep up the good work.

I like the concept you have going on with the glow in the dark, it's a unique nice touch

Also don't beat yourself up over the wrong plastic, I did the same thing when first making my visor. I accidentally bought PET instead of PETG plastic lol.

Used birch plywood instead of MDF or aluminum for my frame. The wood was too close to the upper heating element and went up in flames. It was a great lesson.
