Abstract: Methods of reducing warping of a printed part are disclosed. The method includes depositing a raft comprising a first printable material onto a build platen of a three-dimensional printer. The method includes depositing a support material comprising a second printable material onto the raft. The method further includes depositing an anchor comprising one or more anchor shells of the first printable material onto the raft. The anchor is deposited within the support material. The method further includes printing a part made from the first material above the support material. The securing the part to the anchor by depositing one or more skirt shells comprising the first printable material about the periphery of the part and onto the anchor. The anchor has substantially the same shape as the part.
