Abstract
An improved support structure is provided in a method for making objects by the incremental build-up of layers of a deposition material and adjacent support material. The improved support structure includes a first material and a second material placed as a coating upon the first material. The deposition material, first material and second material each preferably have a selected melting point such that the first material melting point is lower than the deposition material melting point and such that the second material melting point is greater than the first material melting point.
