Abstract
A fused deposition modeling printer comprises a head assembly comprising a heating head. The heating head has a top, a bottom, and a conduit extending between the top and the bottom, wherein the surface of the conduit is adapted to guide a flow of material therein. The heating head comprises an electrically conductive layer along the conduit surface that, when powered, generates heat heating the flow of material traveling in the conduit. One realization uses top and bottom electrical contacts. One realization uses several circumferential electrical contacts to power the heating head.
Claims15
A head assembly for a fused deposition modeling printer comprising:
- a heating head comprising:
- a top;
- a bottom;
- a conduit extending between the top and the bottom having a conduit surface for guiding a flow of material therein;
- an electrically conductive layer providing a resistance along the conduit surface for generating heat when electric current flows within the electrically conductive layer;
- a top electric connector connecting the electrically conductive layer at or near the top of the heating head;
- a bottom electric connector connecting the electrically conductive layer at or near the bottom of the heating head;
- and
- a biasing component pushing at least one of:
- the top electric connector toward electrically conductive layer;
- and
- the bottom electric connector toward the electrically conductive layer.
A head assembly for a fused deposition modeling printer comprising:
- a heating head comprising:
- a top;
- a bottom;
- a conduit extending between the top and the bottom having a conduit surface for guiding a flow of material therein;
- an electrically conductive layer providing a resistance along the conduit surface for generating heat when electric current flows within the electrically conductive layer;
- a plurality of flanges extending outwardly from the conduit each having a circumference surface;
- and
- an electrically conductive trace extending between a first one of the circumference surfaces at first one of the plurality of flanges and a second one of the circumference surfaces at second one of the plurality of flanges via a portion of the conduit surface;
- and
- electrically powered inwardly pressing tightening rings,
- wherein the tightening rings are mounted to the first one and the second one of the circumference surfaces thereby defining an electric circuit therebetween via the conduit surface.
