Question 1

Should 3D-printed models be solid or hollow?

Accepted Answer

Both solid and hollow models can be used, depending on the printer, resin and model design. Solid models are straightforward and robust, while hollow models can reduce resin consumption and printing time. Hollow models require adequate wall thickness, drainage and curing. The resin manufacturer's guidance should be followed for thermoforming applications.
