Shapeways has a pretty good summary of how big (or small) something needs to be to be printable in a given material.

I'm sure a local shop could give you a similar list based on their specific process.

Yeah, that's a good reference. But, for the gate, a lot of those small parts will have to support other elements. In those instances, they will need to be even thicker.

I've printed through Shapeways here in the US and i materialize which is based in Belgium. I don't know about shapeways, but I do know that imateralize has a support staff that reviews your model and can make adjustments or offer suggestions so that it prints correctly.

Hi Eugene,

A bit late to the party on this one, but I was wondering about the markings on the vertebrae you printed? The FDM printing used to produce that model leaves visible layer lines without post-processing, were the marks at all visible on the printed model?

We are testing a new technique using our FDM machine where we are trying to match a POI's quite unique hands to the bruising present on a victim. We have scanned a victim's face and removed the identifying features whilst leaving the relevant morphological aspects intact. This has been printed and will be used as a substrate for an impression that a pathologist can assess for consistency.

Hi Domenic,

You could see part of the deformation of the bone because it was quite severe, but there is no way you could match the cut marks to the same degree. Most of the cut was "smoothed out" in the process, but the print was sufficient enough to get the point across. In truth, I used a virtual model that was packaged in a 3D Viewer. All done in 3ds Max.

Cheers,

Eugene

Great looking models and a good example of what 3D printing can do.

I could not help noticing in the first post that you are looking for a very small human and a person with massive hands :lol: sorry...
If you don't see that there is nothing, then you are kidding yourself.
