A level set based method for fixing overhangs in 3D printing [PDF]
, 2017 3D printers based on the Fused Decomposition Modeling create objects layer-by-layer dropping fused material. As a consequence, strong overhangs cannot be printed because the new-come material does not find a suitable support over the last deposed layer ...
