Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] see Figure 1-3 , a 3D printer with a cooling nozzle, including a protective shell 1, which can protect the 3D printer, effectively prevent external impurities from entering the inside of the 3D printer, prevent printed items from being polluted, and effectively avoid dust generated by the 3D printer The particles are directly scattered in the atmosphere to prevent the dust particles from being directly inhaled and causing harm to the human body. A work...

The invention discloses a 3D printer with a heat dissipation spray head, which comprises a protective casing, a working platform is arranged inside the protective casing, a servo motor is arranged between the working platform and the inner bottom wall of the protective casing, and the protective casing A base is provided on the inner top wall of the base, a hydraulic device is provided at the bottom of the base, a spray head is provided at the bottom of the hydraulic device, a connecting seat is provided between the spray head and the hydraulic device, and the inside of the spray head is provided There is a heat dissipation inner pipe with a spiral shape, and a heat dissipation outer pipe with a spiral shape and cooling fins are arranged on the outside of the spray head. The 3D printer with a heat-dissipating nozzle greatly reduces the temperature of the nozzle, effectively improving the accuracy of 3D printing, avoiding the high temperature of the nozzle and causing other parts to dissolve and burn, so that the temperature on the nozzle can be controlled within a certain range. It greatly reduces the impact of the vibration generated by the water pump on the quality of the 3D printer, and greatly improves the accuracy of 3D printing.
Description
technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printer with a cooling nozzle. Background technique [0002] 3D printer, a machine of rapid prototyping technology, is a technology based on a digital model file, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products. [0003] As one of the core components of the 3D printer, the nozzle of the 3D printer largely determines the quality of the molding. The smoothness of the filament flowing out of the extrusion nozzle and the temperature of the filament directly affect the accuracy of 3D printing. However, if the temperature of the nozzle is too high, other parts will be dissolved and burned, so the temperature of the nozzle needs to be cont...
