1. A non-transitory computer readable medium comprising program instructions which, when the program is executed by a 3D-printing apparatus, wherein the 3D-printing apparatus comprises a nozzle arranged to deposit one or more adjacently arranged filaments of printing material, cause the 3D-printing apparatus to carry out the steps of:
depositing the one or more adjacently arranged filaments of printing material to form at least one layer of the object,
bringing at least one exterior surface of the nozzle into abutting contact with a peripheral edge of the at least one layer; and
