Abstract
A drawing device can include a housing configured for to be held in user's hand, shaped to allow manipulation of the housing like a pen, and include a loading mechanism that supports or drives material toward a nozzle assembly of the device. The nozzle assembly has an exit nozzle from which material can be extruded. The drawing device can be configured to receive a cartridge assembly that can be coupled to the housing and be advancement mechanism and/or an automatic retraction mechanism, and allow for multiple operations, including the readying of additional material to be performed using a streamlined, synergistic activation of components, and facilitate disassembly and cleaning.
Claims20
A handheld drawing device comprising:
- a housing having a longitudinal axis;
- a nozzle assembly coupled to a distal end portion of the housing and comprising an exit nozzle and a heating element for melting pellets of material;
- and
- a loading mechanism comprising a reloading mechanism having an internal volume centered around the longitudinal axis and an aperture at a proximal end portion of the reloading mechanism, and a wave generator mechanism configured to linearly actuate the pellets of material through the internal volume from the aperture to the exit nozzle using a peristaltic motion.
A drawing device comprising:
- a housing having a longitudinal axis;
- a nozzle assembly coupled to a distal end portion of the housing and comprising an exit nozzle and a heating element for melting pellets of material;
- and
- a loading mechanism comprising:
- a reloading mechanism comprising an internal volume and an aperture, wherein the reloading mechanism is coupled to the exit nozzle at a distal end portion of the reloading mechanism;
- and
- an advancement mechanism configured to drive the pellets of material through the internal volume and along the longitudinal axis from the aperture to the exit nozzle.
