I found a BJD doll model and I'm printing it at 50% of its actual size. All the pieces have sliced and printed very well, except the forearm. The problem is this: in the "solids view" it looks fine, but when I apply the "layers view", I see very strange gaps in the upper part of the model. Obviously, when I print it, the output is not the expected. It's the first time something like this happens to me. What can be failing?

I think I've found your problem. The STL file looks OK. The problem comes from the model having thin walls,  so thin that CURA don't print the walls thinner than the orifice or line width. You would have to use a 0,25mm print core to get the model to improve printing but even at 0,25mm it will not be perfect. You can also turn the "Print thin wall" option on in "Shell" settings.

Is this model design to be 3D printed?

 

Good luck!

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
