I posted a follow-up in this thread

https://www.shapeways.com/forum/index.php?t=msg&th=20413 &start=74&

that shows the results of cutting into the FCS and FCP materials on a lathe.

Mr. Nib:
What about Shapeways own 2D to 3D application? To give you a very simple example... When you submit a design through their 2D to 3D application, the orientation is pretty clear. It's a 2D image that will be extruded to 3D. The image you submit is already in the orientation the final model should be printed in. This is especially important if the design contains a word. Shapeways even has a tutorial illustrating this:
https://www.shapeways.com/blog/archives/2566-How-I-Made-vide o-icant-Personalized-Necklace.html

There are no grey areas here. As was noted by other designers who have commented on this thread: there is a very definite front and back to the models printed in SF Plastic. If the model is printed backwards, it is printed incorrectly.

I'd still like to see these differences of "front/back" up/down roughness and have them quantified. Nobody can decipher anyone else's definition of roughness without at least a photo and nobody here wants to debate that on a subjective basis. There's no reason to think that items resulting from the 2d to 3d application are treated any differently from other uploaded models.

Shapeways doesn't even list a surface roughness specification other than letting you know there could be something as bad as ridges resulting from exposed stepped print layer thicknesses. Surely the roughness you are talking about does not exceed this variation? And beyond that about the only specification that is listed for WSF, as an example, is:

"Accuracy ± 0.15 mm, then ± 0.15 % of longest axis"

Unless the roughness causes peaks or valleys that cause this accuracy parameter to be exceeded Shapeways isn't doing anything wrong or unethical. And for those rare cases where badly printed or mistaken prints do get sent out they will generally replace or refund the cost of those prints, at least in my personal experience. Beyond that all you can do is to find a different 3D printing service or purchase a 3D printer to achieve results which are acceptable.

Next year we will see more cars like this , easy to manufacture compared to other robots + metal cutting + paid workers and stuff ... it only needs a little of sanding and it is pristine :D

I put those FCS and FCP test pieces through the ultimate destruction test other than fire and here are the results in photos.
full color sandstone left, full color plastic right:

glued to brass tube with a lot of excess glue smeared all over the place
index.php?t=getfile&id=71341&private=0

sanded with fine grit sandpaper and polished with liquid buffing compund
index.php?t=getfile&id=71342&private=0

the next three images show deeper cuttings into the parts
index.php?t=getfile&id=71343&private=0

index.php?t=getfile&id=71344&private=0

index.php?t=getfile&id=71345&private=0

Some observations:

The color layer thickness of FCP is at least half that of FCS. I probably should have made some thinner layers but that might not have passed FCP rule checking. Maybe next time or someone else can carry this burden forwards.

The FCS appears to have less binder deep inside of it that what I saw in my ornament prototypes last year and the FCP appears similar. In FCP there is some clearer binder just below the colored layer but below that it also gets much more powdery. That powder layer or the lack of it could be causing a lot of the warping we've seen in FCP prints.

There are a lot of defects in the FCP that are difficult to sand and polish out. You can make it shiny but it is difficult to make it as nice and smooth as FCS. It might be worth another try with a different test piece that isn't segmented like this one (i.e. pure surface coloring using textures).

The FCP piece was visually smaller than the FCS oiece and the inside hole diameter was a tad bit larger. The FCS fit snugly on the tube and the FCP was loose enough to fall off and be slightly wiggly before gluing into place.

That's all I got for now.

And once you go past all the outside color layers you get down to the red on the inside of the hole.

index.php?t=getfile&id=71346&private=0

index.php?t=getfile&id=71347&private=0

In the last photo the material was cut until both sides were red and then sanded and polished. There goes about $17 down the drain!

I received my elk sculpture and it was as expected, warped and faded. I threw it in my junk pile of misprints comprising of Shapeways as well as my own misprints. The warping on the antlers were fine, since elk never have perfectly formed antlers, however, there was a depression on the body that was unacceptable. There is no way for this depression to have formed in the printer. The depression was cause by fingers while the object was still soft and the powder was removed from the interior.

Even if the warping could fixed by letting the prints cure properly before handling them, the colors are so far off that I don't see myself ever using this material again unless I wanted to make some flowers of something like that with faded shades of pastel colors.

What else is available besides the Objet500 Connex3?






It always was. It always was because somethingness cannot spawn from nothingness. And in the was of the past there is the forever of the now. Only now. Only now and nothing new, for anything new would add to the infinite, yet there can only be one infinite. Only one. The universe is only becoming something new in the delusion of our minds. This delusion that makes life worth living in our perceived universe becoming.
