Optimizing wall thickness
Objects made with 3D printing are all subject to gravity. Failure to take this into consideration will result in objects that break or droop. We already worked a little with that in remodeling the sword, but it's time to take a more in-depth look.
The first thing to do is to find out the minimum wall thickness specifications for the material you will be printing in. You can find this information on the Web. It differs for each material. For the dragon, which will be printed in gypsum/sandstone, the minimum thickness is 2 mm for a supported wall and 3 mm for a freestanding wall.
