Topic: Trek model advice?

Heya guys,

I've recently been learning how to pull mesh models from various PC games and then attempting to get said models ready to print on  my newly acquired Soli 2 once it arrives.

Having some slight problems understanding whether or not the model needs to be 'thickened' for Slic3r to have a proper chance at making the model viable.
When I've sliced it the results have been a  bit of a rats nest... Bits flying off in random directions, sections with no fill ect ect.

I've run it through NetFabb basic and the cloud based system to fix up any errors in the actual mesh.


So basically I'm asking if the model needs to have a thickness beyond the mesh?
Apologies for the rather basic question... Google has so far failed me....

Perhaps try one of the MeshLab filter, remesh, surface reconstructions to skin it over a little better.

I scaled this up by 8 and sliced it at .1 in RH with slic3r SD3 (and SD2) defaults and it appears to skin over just fine. At lower scale or res it has some gaps but nothing that prevents successful slicing. If you have 13.3cm3 to burn and need an 8 inch star ship that may be an option.

The VCG one seemed to help it out a bit. It can be skinned over at a scale of 5 and .1 res now at least.

Re: Trek model advice?

Yeah, I tried this too, and as Foofoodog said, the model slices just fine.  I noticed that the ship is not flat, rather it's at very slight angle, so I rotated in the "X" axis until the nacells were perfectly horizontal and saved the STL.  Then I imported the new STL into RH, scaled it by ten and sliced it at .1mm and .3mm.

The ships main hull is actually slightly lower than the bottom of the nacells, but with a little bit of support this should print just fine.  Also, for the panels to show nicely, .1mm is the way to go, .3mm will not have nicely defined surfaces, becuase of all the angled and rounded shapes and the convex shape of the saucer.

But in all a nice clean model.  You don't need to run it through MeshLab or anything like that.  Here is the rotated model.

To print or, 3D print, that is the question...
SD3 printer w/too many mods,  Printrbot Simple Maker Ed.,  FormLabs Form 1+
AnyCubic Photon, Shining 3D EinScan-S & Atlas 3D scanners...
...and too much time on my hands.

Re: Trek model advice?

Thanks guys!
Just like that I'm automatically in love with this community!

Didn't quite realise the obvious correlation between the scale of the model and the slice...

I shall post some results once the printer has arrived.

I've begun uploading various Gene Roddenberry inspired models to thingiverse, for any of you Sci Fi fans out there.

And again, thank you all for the help smile
