Diverter for a 3D Printer and a 3D Printer Using the Same

A print head assembly for a 3D printer comprising:

• a heat conduit, a heating element provided on the outer periphery of the heat conduit, a feeding channel provided inside the heat conduit, and further comprising a nozzle provided at the outlet of said feeding channel;
• and
• wherein further comprising a diverter, said diverter comprising an upper end and a bottom end, wherein said upper end is continuously molded and formed into a center column in a direction toward said bottom end, said center column having a plurality of extension walls extending radially outwardly therefrom, said extension walls extending for a length greater than a radius of said feeding channel;
• and
• said nozzle has an outlet and a placement slot wherein said placement slot has a cylindrical second inner wall surface, said outlet having a radius less than the length of said extension wall extending;
• and
• wherein said diverter is provided within said placement slot at an angle between every two adjacent said extension walls and forms a storage bin with a second inner wall surface of said placement slot;
• and
• when the print material enters said feeding channel, said heating element carries out heating and transfers heat to the print material and melts it, and the melted print material is diverted through said shunt and stored in said storage bin, and when said print head assembly performs a print job, the melted print material stored in said storage bin is discharged through said outlet.

A method of increasing the printing speed of a 3D printer comprising a diverter for a 3D printer, said diverter having a center column, and a plurality of extension walls extending radially outwardly from said center column, wherein said extension walls extend for a length that is greater than a radius of said feeding channel of 3D printer;

• and
• setting said diverter in a feeding channel of said 3D printer, wherein said diverter forms a storage bin in said feeding channel;
• and
• heating and melting the print material entering said feeding channel;
• and
• guiding said printed material after melting through said diversion of the diverter into said storage bin;
• and
• the melted said print material stored in said storage bin is extruded out of the nozzle of said 3D printer and a 3D printing operation is performed.
