Simplify3D is a 3D printing software that allows you to customise and control the settings for your 3D prints to a professional level. One of the initially useful features is the ability to customise the support structure you use to reinforce the overhangs. Being able to do this allows you to experiment with different densities and position supporting material in problem areas to achieve optimal results on your prints.
Adding custom supports is very simple to do and can be edited and adjusted to achieve the best results, take a look at our video below for a more in depth explanation:
