Embodiment 1

[0056] This embodiment provides a food microwave 3D printing equipment, such as Figure 1 to Figure 3 As shown, the food microwave 3D printing equipment includes: a focused microwave heating unit and a material extrusion unit; the focused microwave heating unit includes a microwave heating cavity 20 and a microwave heating antenna 21, wherein the microwave heating antenna 21 is a bipolar antenna , including an anode antenna 22 and a cathode antenna 23, which are arranged inside the microwave heating cavity 20.

[0057] The material extruding unit includes a barrel 10 and an extrusion nozzle 11; the extrusion nozzle 11 is arranged between the anode antenna 22 and the cathode antenna 23, and the anode antenna 22 and the cathode antenna 23 limit the microwave electric field to the anode antenna 22 and the cathode antenna 23. The position between the cathode antennas 23 realizes focused heating of the extruded material and achieves the effect of instant curing of the extruded mate...

Embodiment 2

[0077] This embodiment provides a food microwave 3D printing system, such as Figure 12 and Figure 13 As shown, the food microwave 3D printing system has image processing functions integrating scanning imaging, image processing, and slice processing. The food microwave 3D printing system includes: a scanning imaging unit, a control unit, a focused microwave heating unit, a 3D printing unit and an anti-leakage unit.

[0078] The food microwave 3D printing system obtains the image information of the target object by scanning the imaging unit, and sends it to the control unit. The control unit slices the image of the target object through cura, and sends corresponding instructions to the 3D printing unit to complete the printing of the shape of the target object. At the same time, the corresponding microwave power is set through the control unit to make the focused microwave heating unit complete the heating treatment.

[0079] The various components of the food microwave 3D p...

Embodiment 3

[0091] This embodiment provides a food microwave 3D printing method, which is applied to the food microwave 3D printing system described in the second embodiment above. The methods include:

[0092] Open the switch button 37 of the cabinet, and add an appropriate amount of food slurry in the barrel 10.

[0093] The target object is placed on the storage table 2 of the three-dimensional scanner 1, and the target object is scanned, and the generated image information is transmitted to the image signal converter 5 through the signal transmission line 4, and the image signal converter 5 automatically converts the image file into an stl format file .

[0094] If there is no target object, the image file of the target object can be directly imported into the image signal converter 5 through the USB interface, and the image signal converter 5 will automatically convert the target file into the stl format.

[0095] According to the appropriate printing parameters, use the built-in c...

Abstract

The invention discloses food microwave 3D printing equipment, a system and a printing method, and belongs to the technical field of food. By setting a bipolar microwave heating antenna, focused heating of a material in an extrusion nozzle is realized; meanwhile, the bipolar microwave heating antenna breaks through a traditional multi-mode cavity heating method, the volume of a heating cavity is greatly reduced, and integration with a desktop-level 3D printer is facilitated; a microwave switch is controlled through an extrusion command, the synchronization of extrusion and heating is realized,and the uniformity of heating is improved; the integration of the model making, slicing and 3D printing processes is realized by jointly operating a three-dimensional scanner, a slicing software and the 3D printer; and according to the food microwave 3D printing equipment and the printing method, the material in the extrusion nozzle can quickly and centrally heated to realize the immediate solidification of the extruded material, so that the extruded material has higher mechanical strength, the molding quality of printed products is improved, and the problems of deformation and collapse of theprinted products are effectively solved.

Description

technical field [0001] The invention relates to food microwave 3D printing equipment, a system and a printing method, belonging to the technical field of food. Background technique [0002] 3D printing is a kind of additive manufacturing technology, which is different from traditional subtractive manufacturing such as lathes and engravings. According to the instructions of the control system, the parts are manufactured in a layer-by-layer manner. In recent years, 3D printing technology has developed rapidly in the industrial field and has been widely researched and applied. In the field of food, due to the high moisture content of the system, food 3D printing mainly uses Fused Deposition Modeling (FDM) technology for molding. Generally, the food material is made into a molten state or a slurry, placed in the extrusion barrel, and the food slurry is extruded from the barrel through the extrusion of a piston, air or screw, and accumulated and formed on the printing platform. ...
