Build a printable 3D object

Hello,

I am building a 3D from a shape solid by extruding in Z dimension based on a value. I then add an image texture on the front face and finish with a .obj writer.

The shape consists of 31 features, each greater containing the previous ones, and with quite complex shapes (numerous vertex).

I manage to produce a visualisable 3D object with texture (I can also visualise it in GLC player) but when I try to upload it on a printer website (such as Sculpteo), further processing cannot be done because the object is not valid, with lots of singuliar edges, and I don't understand why.

What tools can I use in FME to clean the object without changing its layout? I can send the input shapefile, the image used for the texture (though I'm pretty confident this is not the problem) and the workbench if needed. I can also send some screenshots of the diagnosis generated by the printer website.

Thanks a lot!

Jean

Hi @jportemer,

What kind of errors are you getting from the 3d printer website? I took a look at Sculpteo's FAQ and noticed that for OBJ, it expects both the MTL and OBJ to be inside a zip file. Is that what you have already done?

 

As for simplifying the model in FME, I'd suggest giving the MeshSimplifier a try before writing it out to OBJ to reduce the number or vertices.

 

In this Q&A; Question, changing their writer to SketchUp seemed to work out for them, though OBJ should work fine for Sculpteo.
