摘要：
A cartridge assembly (3) of a 3D printer system for printing a plastic substance, such as a dough, comprises a refillable cartridge (31) and a punch-fill adapter (32) having a circumferential cutting edge (26) and being provided with a punch-fill connector (24) to form a manually releasable inter-connection between the cartridge and the punch-fill adapter. When said inter-connection is effective, the cartridge assembly is effective as a manual tool for punching, by means of said circumferential cutting edge, punched slices out of a supply slice of said plastic substance, and thereby for automatically inserting said punched slices into the inner space of the cartridge. Thanks to this punch-fill connector the manual (re)filling of the cartridge can be performed more easily and more reliably.
