Title: 3D printed German armoured cars
Post by: monk2002uk on 27 April 2020, 11:05:46 AM

Some SLA resin prints of the German Sdkfz 221 in 1:285 scale:

Ruler has cms on near edge and inches on far edge.

Looking good. 👍

Those look very good.  Very smooth surface and good detail.

It would be interesting to see them cut off the printing foundation and comparisons to other similar scale miniatures.

Nice neat results!

I'd be inclined to remove all the supports that are touching the sides, shouldn't be needed. 

I guess these are commercial?  I find that a dip in hot water before curing softens the supports and makes them a lot easier to remove neatly

Thank you. The original STL files were distributed under a Creative Commons licence, preventing commercial exploitation (even if I wanted to, which I don't). The support locations have been modified - the advantage of doing test runs.

I will try and put some comparisons together of free-standing models versus metal equivalents. The great thing about 3D printing is the ability to produce vehicles that aren't available otherwise.

Here is a comparison between the 3D printed model featured earlier and a GHQ Models armoured car (later variant). Will post a painted version of the printed model as soon as I can. This will bring out more of the details.

Thank you!

Yeah, that’s a seemingly excellent scale match.

So the stl filed are free, then?

Yes, the files were created courtesy of Marcus Bergman in the main - available on Thingiverse. Search with 'Sdkfz' and m_bergman as the creator.

And a Stug IIIB for good measure:

Nice.

What resolution?

Nice! I'm currently trying to get into this 3d printing thing myself. Its nice to see some great results! 8)

Here is a slightly better angle and lighting. The layers are 25µm thick.

That's pretty excellent. It does appear that 6mm cast metal vehicles will soon be obselete.

If you don't mind me saying there seems to be a lot of "waste" on each printing.  Is it recyclable, or do you just have to bin it?

What printer?

Title: Re: 3D printed German armoured cars
Post by: monk2002uk on 15 May 2020, 07:43:04 PM

The printer is a FormLabs Form 3 resin printer. You can get similar results with MARS or equivalent resin printers, which are much cheaper.

The raft and scaffolds are not re-usable. I can reduce the footprint by setting the item at or near perpendicular to the print platform.
