Abstract
A method of printing a three-dimensional (3D) object and a support construction for the 3D object includes depositing a model material, layer-by-layer, on a fabrication platform, to print a first portion of the 3D object, and depositing a support material, layer-by-layer on the fabrication platform, to print the support construction, wherein, in a predetermined number of the deposited layers, the model material and the support material are deposited such that a gap is formed between a surface of the first portion of the 3D object and a surface of the support construction.
