Stupid question from me about 3d coat vs Netflabb.  I did not realize that 3d coat was a full blown modeling program.  Checked out the video.  Looks like really interesting modeling tools!.  Will investigate further.  I do need a very fast and efficient method and i have already spent a lot of time learning Blender for my modeling needs.  Maybe the Netfabb approach seems easier?.  Just drag a few slider and then done'?

Wishgranter,  thank you so much for offering assistance!.  Greatly appreciated.  I have been pulling my hair on this matter for a few days.   I will email  a download link.

 I would really like to know for future project how to do this though.   What software are you using? 

Netfabb also has a private version for only 300USD that has the shell function. Do you guys think it has the functions i need?   I am mainly after the shell function. 

 Chris D,  Do you think Netfabb could generate a shell for the attached model?   It is a picture  of an actual print that was printed solid.  I am worried it will go wrong on the small details such as the wooden branches and encrustations on the cannon. 

Does Netfabb destroy the UV mapping or is it kept intact?  I like to print in color so keeping the textures intact is important.  Pros- Cons 3d -coat vs Netfabb?

Hi,

I need to shell (hollow out) a few photosscanned models for 3d print.  The prints would be to expensive solid. One is a scan of a 10.000 year old skull and the other is cannon. Images captured under water.  The models are very detailed.  Around 1 millon faces.  The skull have many small extrusions and the cannon large nr of small details. 

I use Blender for modeling. Normally the solidify command works very well on hand modelled meshes.  But not on these.  There are details that are smaller then 1mm and if i set the thickness to anything more then 1mm lots of artifacts are introduced.  As these are archeological artifacts they need to be exact and not deformed in any way.  I need a wall thickness of 2-3mm. 

So i have tried Meshlab using the uniform mesh resampling filter.  This almost works but not quite yet. 

Are there any software that would work for me?  I have Netflabb basic but that does not have the shell feature.  The Pro version is 1500USD.  If it works it would be worth the money but with no trial version i am hesitating to buy it.  Lot of money wasted if it does not work. 

So have anyone tried Netflabb Pro on complex models with small details and found it worked?  Any other software that can do the trick? 

If anyone would like to help i could send you the files and you can have a go with them. Would be great if someone that has Netflabb pro could try if the shell command works on my models.  If so i can buy it without remorse.
