Zusammenfassung:	The use of compatible, semi-miscible or miscible polymer compositions as support structures for the 3D printing of objects, including those made from polyether-block-amide copolymers such as PEBAX® block copolymers from Arkema, polyamides such as RILSAN® polyamides from Arkema, polyether ketone ketone such as KEPSTAN® PEKK from Arkema, and fluoropolymers, such a KYNAR® PVDF from Arkema, especially objects of polyvinylidene fluoride and its copolymers. One particularly useful miscible polymer is an acrylic polymer, which is miscible with the fluoropolymer in the melt. The support structure composition provides the needed adhesion to the build plate and to the printed object and support strength during the 3D printing process, yet it is removable after the fluoropolymer object has cooled. The support polymer composition is selected to be stiff and low warping, yet flexible enough to be formed into filaments.
