3D Printed Parts

Hi all, does anyone know anything about 3D printing parts? I assume in 1/72 it's harder than 1/35 owing to the scale, but I have no clue.

Any good websites for plans?

Basically I'm wondering if printing zimmerit is possible? I'd imagine not due to the thickness but if you don't ask...

I actually get quite a bit of 3D printing done but it's in my work rather than for my hobby. I use a commercial 3D printing service that uses Stratsys machines and upload cad files to get the parts printed. I mostly use them for one off pieces of tooling. I've certainly thought of using them for modelling. However I'd say they aren't entirely there yet for fine parts.

There are basically 2 main technologies, FDM which is done by melting a spool of plastic rod along the pattern of the part and stereolithography, where a bath of resin is fused with a laser. Parts made with FDM have what I call a corduroy finish, whereas stereolithography can give quite fine detail, edit it's much slower and more expensive to do.

If i were going down that route I'd look at something like the Tiko it looks pretty cool, but I'm not sure if you can buy one anymore

Both would work for something like zimmerit, but not at 1:72 scale, I think the resolution wouldn't be high enough. Also with an FDM printer your thinnest feature would be limited by the thickness of the plastic reel you were using, which would typically be 1 to 2mm in diameter.

There is a company called Shapeways that a lot of modellers use. I don't think zimmerit would be possible in 1/72.



If I was attempting zimmerit in 1/72 I would use greenstuff or no more nails and try scribing the pattern with a razor saw blade either on of RB productions blades or JLC Blade

I've heard that either a very small screwdriver heated and applied in rows or making up a mix of liquid adhesive and plastic and painting it on followed by
the screwdriver again works. I'd be nervous with either tbh.

Thanks lads! And what about 1/35? I reckon I'll be investing in some of them trumpeter rollers or (I think Tamiya) scribes anyway!

They seem to have some lovely stuff and the prices aren't bad. It mostly looks like stereolithography. But there's nothing in 1:72 which is my preferred scale :(

Yeah they're both good. The trick is to get the putty really thin

I've heard the best way to do it is to roll it out thin first (to shape) and then stick it on, essentially.

I think Andy's Hobby Headquarters on YouTube did a tutorial for a 1/35 Brummbär

I used the Modelkasten zimmerit tools on my unfinished tiger and did as you said - rolled it out using talcum powder then stuck it on and used the rollers and stamps

Thanks Pat, looks well! To scale, as you say, is the most important thing.
