A typical 3D printing technique is Fused Deposition Modeling (FDM), in which printer nozzles build objects by selectively depositing molten material in predetermined paths layer by layer, using thermoplastic polymer strands. The temperature at and near the printer nozzle is typically high due to the need to heat the print strands to melt them.

Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

As described above, the temperature of the printer nozzle of the 3D printer and its vicinity is generally high due to the need to heat the printing wire to melt it. In addition, when high-speed printing is performed, the internal temperature of the 3D printer may be higher. When the temperature is too high, damage may be caused to components of the 3D printer, and the printing quality of the printed material may be affected. Therefore, the internal space of the 3D printer and the printer nozzle need to be cooled.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 shows a schematic diagram of a 3D printer 100 according to an embodiment of the invention; fig. 2 shows a schematic view of the 3D printer 100 of fig. 1, wherein fig. 2 hides one of the side walls of the 3D printer 100 in order to better show the internal components, according to an embodiment of the present invention; fig. 3 illustrates a side view of the 3D printer 100 of fig. 1, according to an embodiment of the invention; and fig. 4 showsbase:Sub>A cross-sectional view of sectionbase:Sub>A-base:Sub>A' of the 3D printer 100 in fig. 3, according to an embodiment of the present invention.

Referring to fig. 1 to 4, an embodiment of the present invention provides a 3D printer 100. The 3D printer 100 includes: a case 110, the case 110 defining an inner space; a printer nozzle 120, the printer nozzle 120 being disposed in the inner space, for heating the printing material and extruding the heating-melted printing material; a printing platform 130, the printing platform 130 being disposed below the printer nozzle 120 for depositing a printing material; and a cooling assembly 140.

The cooling module 140 includes: a fan 141 provided on a sidewall of the case 110 for drawing air in the external environment into the internal space or discharging air in the internal space to the external environment; and an air duct 142, the air duct 142 defining a first port (a port above the air duct 142 in fig. 2) arranged toward the printer nozzle 120 and a second port (a port below the air duct 142 in fig. 2) arranged to face the fan 141 such that: when the fan 141 draws air in the external environment into the internal space, the air in the external environment enters the air duct 142 through the second port and then enters the internal space through the first port; or when the fan 141 exhausts the air in the interior space to the outside environment, the air in the interior space enters the air duct 142 through the first port and is then exhausted to the outside environment through the second port.

Accordingly, the fan 141 and the air duct 142 having a port facing the printer nozzle 120 accelerate the flow of the air in the internal space of the 3D printer 100, particularly accelerate the flow of the air through the printer nozzle 120 having a relatively high temperature, thereby cooling the internal space of the 3D printer 100, particularly the printer nozzle 120, to prevent the components of the 3D printer 100 from being damaged by overheating, and to accelerate the cooling of the printed material.

In some embodiments, as shown in fig. 4, the cooling assembly 140 may further include a filtering device 143, and the filtering device 143 may be disposed within the air duct 142 for filtering air flowing through the air duct 142. Therefore, on one hand, when the fan 141 sucks air in the external environment into the internal space, dust in the air can be filtered out, so that the dust is reduced or prevented from being attached to parts of the 3D printer 100 to interfere the normal operation of the parts, and the dust is prevented from being attached to a printed part to reduce the printing quality; on the other hand, when the fan 141 discharges the air in the internal space to the external environment, the filter device 143 may reduce or prevent the odor in the internal space from being discharged to the external space, thereby reducing or preventing the pollution to the external air environment.

In some embodiments, as shown in fig. 4, the first port may be disposed at the same height as the tip of the printer nozzle 120. Thus, more air flow can be made to flow through the printer nozzle 120, heat dissipation efficiency to the printer nozzle 120 is improved, and print quality of a printed product in a high-speed printing process is improved.

It should be understood that arranging the first port at the same height as the tip of printer nozzle 120 may mean that the first port is approximately the same height as the tip of printer nozzle 120. For example, the height of the first port may not differ by more than 20 millimeters or 30 millimeters from the height of the tip of the printer nozzle 120. Accordingly, the air outlet angle of the first port can be adjusted appropriately, so that more air flows through the printer nozzle 120.

In some embodiments, the first port may have a flat shape extending in a planar direction parallel to the upper surface of the printing platform 130. From this, can increase air supply area or air-out area to the air current velocity of flow of increase first port department, thereby promote the radiating effect.

In some embodiments, as shown in fig. 2 and 4, the fan 141 may be disposed on an inner sidewall of the cabinet 110, and the wind tunnel 142 is located in the inner space. The fan 141 draws air in the external environment into the air duct 142 or discharges air in the air duct 142 to the external environment through an opening on a sidewall of the case 110. Thus, during operation of the 3D printer 100 or during handling of the 3D printer 100, the side walls of the box 110 may provide protection for the fan 141 and the air duct 142 from damage; in addition, the 3D printer 100 can be made more compact and beautiful as a whole.

Fig. 5 shows a schematic diagram of a 3D printer 100 according to an embodiment of the invention. To better illustrate the internal components, fig. 5 hides one of the side walls of the 3D printer 100.

In some embodiments, as shown in fig. 5, the cooling assembly 140 may also be disposed on an outer sidewall of the case 110. A first port (a port above the air duct 142 in fig. 5) of the air duct 142 communicates with the inner space of the case 110 through an opening in a side wall of the case 110. Thus, the fan 141 and the air duct 142 are disposed outside the case 110, so that the fan 141 and the air duct 142 can be easily installed, repaired, or replaced.
