Description

Printer head convenient to dismantle

Technical Field

The utility model relates to a FDM 3D printer technical field.

And more particularly to an FDM printhead that is easily removable.

Background

FDM is a shorthand form of "fused deposition modeling", i.e., fused deposition modeling. Typically, 2D printing is done on a piece of paper (on a flat surface), while 3D printing is done on a solid model. FDM, popularly speaking, melts a material into a liquid state at a high temperature, and then solidifies after being extruded through a printer nozzle, and finally forms a three-dimensional real object in a three-dimensional space. The FDM 3D printer extrudes and molds the melted liquid material through the printer nozzle, so the requirement on the printer nozzle is high, and the printer nozzle is easy to damage or block after long-time printing, so the printer nozzle needs to be replaced to ensure the precision of the FDM 3D printer.

Present FDM 3D printer nozzle all is integrative design, and the printer nozzle damages or can't change or maintain after the precision reduces, causes the wasting of resources. Some FDM 3D printer can change the printer nozzle, but the printer nozzle passes through screwed connection, need wait earlier the printer nozzle cooling down when changing at every turn, then pull down the printer nozzle of damage, pass through the screw with new printer nozzle again and fix, change the completion back because the material that melts in the FDM 3D printer has cooled down, need heat up again and just can work. This process wastes a large amount of time, and the process of replacing the printer nozzle is more tedious, increasing the labor intensity of the worker.
