NovaCast, a mexican mediprint, creates customized 3D printed Plaster cast which overweighs normal plaster in every concept. It doesn't absorb sweat, causes less skin infections, is 1/10th light-weighted, invisible to x-rays and you can take bath while wearing it. There's no way ordinary plaster can beat this 3.5 hours-to-make 3D printed plaster cast.
