Abstract
A print head for a 3D printer can receive a syringe of printing material which controllably exits through a needle or nozzle. The print head has a misting port through which a mist of the chemical cross-linker flows around the printing material for curing. The print head further includes an extraction port for extracting excess chemical cross from around the printed object.
Claims24
A misting attachment for use in a material deposition process, the misting attachment comprising:
- a receiver for receiving a deposition head having an exit nozzle through which a material can be deposited;
- a mist delivery channel in proximity to the exit nozzle of the deposition head when present, the mist delivery channel arranged to supply a flow of across-linker or suspension of particles around the material being deposited through the deposition head;
- and
- a mist extraction channel in proximity to the exit nozzle of the deposition head when present, the mist extraction channel arranged to extract a flow of excess cross-linker or suspension of particles from around the material being deposited.
