I did quite some color prints in the past and thought I had my workflow down.

However I had quite some difficulty when I tried to upload a color model the last few attempts. The error emails do not specify what the problem is however only that I need to give my model a bit of extra love.

I took the existing grandpa model and made a 'sinterklaas' version of it (hope the family will be amused next december

I kept the triangles well under 500.000 did all kinds of error checks... Also I opened the wrl in notepad to make sure the texture name and path check out.

Below are 2 exports of exactly the same source. One is a .STL without color. The other is a .WRL with texture.

imageafter.com/temp/tristan/SinterOpa3STL.zip
imageafter.com/temp/tristan/SinterOpa3WRLcolor.zip

The STL uploads perfectly however the .WRL 'needs more love'

Anyone an idea what is wrong?

Does the server check wall thickness when uploading an .WRL? If so that could be the problem since the wall thickness of colored sandstone is 3mm and the white strong and flexible is 0.7 but I guess if that is checked it would be easy to mention in the error email right?

I'll take a look.

Any luck with uploading one of your old models?

Also the guidelines for sandstone have been updated and 2mm walls are also possible now:

And the polygon limit has been upped to 1 million

btw here is a link to the succesfully uploaded stl file: http://shpws.me/lPPX

I had another 3D print issue a few months back that was solved by reducing the triangles to 300.000 instead of 450.000 which was my original size. apparently a memory issue.

I've downloaded en re-uploaded this model of the less funky grandpa: http://shpws.me/lnKA

I've yet to receive confirmation but that seems to be a good sign. The error of sinteropa where very quick after uploading... ]]> tristan_bethe 2012-10-29T12:38:36-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=56158&th=11389#msg_56158 tristan_bethe 2012-10-29T12:41:03-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=56159&th=11389#msg_56159 Sounds like that might be it, but the email should just say that if that is the case
Should be easy enough to test though, scale it up and see

Oh and in my experience, old models that do not adhere to the rules may or may not be rejected on ordering
Likely depends on the actual repeat printability.

See if you can find any differences between the files.
I have limited pc access atm.
But perhaps, spaces/newlines/dos/unix filetype or format issues?

Hi Tristan, Uh oh! Seems like your model needs a bit more love before our robots can work their magic. The 3D model Opa via meshlab you recently uploaded didn't pass all our automated checks, so it's not yet ready for 3D printing. Our tutorials and FAQ can be super helpful for more detailed information, or you can always ask the community a specific question on our forum If you're stuck or have any questions, don't hesitate to reach out at service@shapeways.com. Please include the file attached to the email, as well as any notes on your design, so we can help you solve your problem as quickly as possible. Kind regards,

The floating loose verts were the culprits. Dimensions and volume remain the same with the wrl fixed.]]> Fredd 2012-10-29T19:41:25-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=56460&th=11389#msg_56460
Thanks so much for checking it out. Just read your reply since for some reason I am not getting alerts on new posts anymore

May I ask what software you used to check and how you fixed it eventually?

Also do I understand correctly that the SW upload does automatic booleans with intersecting meshes? That would help me understand/visualize the SW upload a bit better!

I opened the file in Blender, nice little free program. For the uses would would need of it, would be simple to learn about 5 techniques.
By the way, I loved Pope Pawpaw.
