Re: The Eighth Passenger
Hello everyone,
Yesterday I printed the torso. It all seems ok, right? Instead, no!
I put too polyurethane and the rear wall of the mold, ie the back, it is inflated and remains deformed, due to the pressure and the heat of the polyurethane. I'll have to redo this wall with fiberglass, also more robust. I will have to reduce the foam density to 127 kgm / m3 instead of 150kg / m3. 127 kgm / m3, the minimum amount should be sufficient.
This part it could recover, but it's quicker to do it again. I'll try to retrieve the inner frame, but if I see that it is too strenuous, also redo this, which is a paltry expense.
It's a nuisance, because I thought I had finished with fiberglass. Patience, my fault. I should have been more cautious. Probably the legs have held up well because the relationship between the fiberglass thickness and width of the surface of the walls of the mold is greater. For example, as the difference between bending a long and one short iron rod, which have the same diameter.
In between I also made the second leg.
