Filament dryer
An apparatus for heating three-dimensional printing filaments comprising a heating chamber including an insulation lining and spool holders mounted at a base of the heating chamber, a heater fan assembly mounted above the heating chamber, wherein the heater fan assembly comprises a powered fan and heater configured to heat air and circulate the heated air to the heating chamber, and a diverter situated between the heater fan assembly and the heating chamber, wherein the diverter splits and directs the heated air to the heating chamber through a pair of channels. The apparatus further comprising a plurality of exhaust ports at top sidewall portions and bottom sidewall portions of the heating chamber, wherein the plurality of exhaust ports allowing the heated air to escape from the heating chamber, and fitting adapters comprising apertures that allow filament material to be dispensed from the heating chamber.
1. An apparatus for heating three-dimensional printing filaments, the apparatus comprising:
a heating chamber including an insulation lining and spool holders mounted at a base of the heating chamber;
a heater fan assembly mounted above the heating chamber, the heater fan assembly comprising a powered fan and heater configured to heat air and circulate the heated air to the heating chamber;
a diverter situated between the heater fan assembly and the heating chamber, the diverter splitting and directing the heated air to the heating chamber through a pair of channels;
a plurality of exhaust ports at top sidewall portions and bottom sidewall portions of the heating chamber, the plurality of exhaust ports allowing the heated air to escape from the heating chamber; and
fitting adapters comprising apertures that allow filament material to be dispensed from the heating chamber.
2. The apparatus of claim 1 further comprising a computing device configured to control operations of the heater fan assembly.
3. The apparatus of claim 2 wherein the computing device is configured to utilize and operate the heater fan assembly to heat the air and maintain an air temperature within the heating chamber at a given configurable temperature based on a material setting or a user-defined setting.
4. The apparatus of claim 2 further comprising a touch screen that allows user interaction with the computing device to control heating modes and the operation of the heater fan assembly.
5. The apparatus of claim 4 wherein the touch screen is configured to present a graphical user interface including at least one of presets, dryer status, countdown timer, current and setpoint temperature, and a logo.
6. The apparatus of claim 1 wherein the heater fan assembly includes an air filter.
7. The apparatus of claim 1 further comprising a dryer door that provides access to the heating chamber.
8. The apparatus of claim 7 further comprising an interlock that toggles activation of the heater fan assembly based on a configuration of the dryer door.
9. The apparatus of claim 1 wherein the diverter splits and directs the heated at an outwards angle towards sidewalls of the heating chamber.
10. The apparatus of claim 1 wherein the diverter is triangularly-shaped or angularly slanted.
