I just received my first 3d printed model and there are some issues which i could use some help with.

I have 2 questions -

How do i get Shapeways to recognize hollow areas - it seems as though they were ignored completely and filled solid with print material.
In 3DSMAX i created the hollow using a Boolean subtraction rather than Shell, was this a mistake?

Also, has anyone attempted to create small tubes using FUD and what are the smallest tubes physically possible? I need tubes that are as small as FUD will allow and they need to be functional -they will transport liquid within them. The tubes from the model i received today were fused solid, although it seems the 3d printer did at least make an attempt at them .

Thanks in advance folks,

For your FUD tubes, it's probably the support material inside them. Try soaking it in nail varnish remover for 10-15 minutes. May take a couple tries to get it all out.]]> Youknowwho4eva 2013-02-08T21:05:11-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=61633&th=12770#msg_61633
To be honest i think the tubes were kinda my fault, i tried to make them .5 mm ID and 1mm OD, oops . I'm just wondering if anyone has done anything similar. At least i learned that .5mm ID is too small for transparent detail.

Thanks for the answers.]]> Mechanical 2013-02-08T21:18:27-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=61634&th=12770#msg_61634 material. So it's an actual hole in the model

Transparent detail and FUD are two different things. The minimum clearance for FUD is .05mm I haven't made tubes in FUD myself, but that suggests the sizes you used would work, as long as you can clean out the support material. If you used transparent detail, the minimum clearance is 2mm. ]]> Youknowwho4eva 2013-02-08T21:26:57-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=61773&th=12770#msg_61773 GWMT 2013-02-11T05:46:57-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=61787&th=12770#msg_61787
That's great thanks, i have a model ordered that has .6mm ID tubes, hopefully it turns out ok and i'll let you know the results for other peoples future reference, thanks again,
