MATERIALS THAT MODIFY THE INTERFACE PROPERTIES OF PRINTED MATERIALS FOR OBTAINING OBJECTS WITH IMPROVED STRENGTH

摘要

The invention provides a method for 3D printing a 3D printed item (10), wherein the method comprises depositing printable material (201) to provide 3D printed item parts (1320) on top of each other or next to each other, with the 3D printed item parts (1320) forming said 3D printed item (10), wherein the 3D printed item parts (1320) comprise polymeric printed material (202), wherein the method further comprises providing at least a set of two 3D printed item parts (1320a, 1320b) and binding these together with one or more of a chemical bonding and an electrostatic bonding. The invention also provides such 3D printed item, which has an enhanced strength due to the additional bonds.
