11097466 · 2021-08-24 · ·

A method and system are disclosed. A method of printing onto a base having an upper surface spaced from a lower surface by a base thickness includes dispensing a yarn from a nozzle of a printing system and selectively attaching the yarn to a first attachment region. The step of dispensing the yarn includes dispensing a heat-moldable material and a melt-resistant material. The step of selectively attaching the yarn to the first attachment region includes moving the nozzle into the first attachment region. The step of moving the nozzle into the first attachment region reduces the base thickness by a prodding distance. The heat-moldable material bonds to the first attachment region.
