Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in further detail with reference to the accompanying drawings, and the present invention is not limited to the embodiments.
Fig. 1 is a partial sectional view for explaining the present invention, and fig. 2 is a sectional view for explaining a use state in fig. 1.
As shown in the drawing, the base 100 provided in the 3D printer of the present disclosure is a member that forms a shaped object by laminating raw materials extruded by the extrusion unit 200.
Among them, a general 3D printer has a disclosed technical structure, and includes: a cavity which is a space for forming a shaped object inside a not-shown case; an extrusion part that extrudes a material to be molded into the cavity; a bracket to which the pressing part is attached; a moving unit that moves the carriage; a control unit that controls the pressing unit and the moving unit; and a base for laminating the raw material extruded by the extrusion part to the cavity and molding the molded object.
The 3D printer may use metal or synthetic resin as a raw material, or may use chocolate or the like as a food material in some cases.
In addition, since the 3D printer is generally provided with a heating means on the base, when the molded object is made of synthetic resin, the molded object can be easily separated.
However, in the case where a shaped object is molded from a raw material such as food chocolate and then separated from a base, cooling is required, but the base provided in a conventional 3D printer cannot be provided with a cooling means.
The utility model discloses can be according to the material of the molding in the base, selectively heat or cool off to follow the fashioned molding of base separation simply easily.
Possess in according to the utility model discloses a 3D printer base 100 embeds there is: the peltier element 10 is stacked in a hollow box shape on the upper surface, and is heated or cooled depending on the material of the molded object 110.
The peltier element 10 may be provided on a general rack or a space holding port or a rail inside the base 100, and is preferably provided in a form removable from the rail for easy maintenance.
As described above, when the peltier element 10 uses a phenomenon that the temperature difference between both ends of the plurality of layers of the conductive material is continuously generated during the power supply, and the opposing high-temperature portion requiring the low-temperature cooling is forcibly cooled, the heat of the low-temperature portion is transmitted to the high-temperature side. According to the law of conservation of energy, when one side becomes cold, the other side inevitably becomes hot.
In other words, the basic principle is that: when electrons move between two metals with potential difference, energy is needed, and the needed energy is taken from the energy held by the metals, and the principle is as follows: switching the direction of current movement changes the flow of electrons and holes, as a result of which the faces that emit/absorb heat also become opposite.
The base 10 is preferably made of a metal material having excellent thermal conductivity, and ceramics or the like may be applied as necessary. In this case, the base may be provided with a non-illustrated one-way check valve on either the upper surface or the side surface thereof, so that the base is easily discharged to the outside when the inside of the base is heated or cooled to a temperature higher than a set temperature. Preferably, the base further includes a normal temperature sensor for sensing the temperature inside the base.
Also, it is preferable that either one of the side surfaces or the bottom surface of the base 10 includes: an openable or closable or detachable or slidable door/window 102 which is opened or closed in the disclosed manner to facilitate the removal of the peltier element 10. That is, the door window is provided with a simple and easy-to-replace door window when the Peltier element built in the base is abnormal.
Due to the above structure, according to the basic flow of the 3D printer of the present invention, the raw material extruded from the extruding portion is sequentially stacked on the base, and the extruding portion moves and forms the desired molded object according to the input shape.
When the shaped object is molded into the shaped object having the desired shape of the base, the process is started depending on the material of the molded shaped object, that is, when the shaped object is a synthetic resin, the upper surface of the base is heated by the peltier element provided in the base, and the molded shaped object is smoothly separated from the upper surface of the base.
When the shaped object formed on the upper surface of the base needs to be cooled, for example, chocolate which is a food product is used, the upper surface of the base is cooled by the peltier element provided in the base, and the upper surface of the base is cooled, thereby smoothly completing the separation of the formed shaped object.
The peltier element may be opened/closed in a known manner by manual operation of an operator, and may be connected to a control unit of the 3D printer to automatically heat or cool the object depending on the material of the object to be molded.
Therefore, the utility model discloses built-in plain type technical component, promptly, can heat or cool off the inside peltier element of base to being equipped with can be according to the shaping in the material of the modelling thing on the base heats or refrigerated condition, when further promoting the convenience of use, makes the modelling thing of shaping on the base not impaired, does not damage, and is safe easy during the separation, and efficiency is extremely high.
Fig. 3 is a sectional view for explaining another embodiment of the present invention, and fig. 4 is a sectional view for explaining a use state in fig. 3.
The above-described members shown in the drawings also provide a technical member which makes it easier to mold a shaped article when the shaped article is molded using a single material such as food chocolate.
The chassis 100 further includes: and a cold air supply unit 20 for supplying cold air to the upper side of the base 100 when the peltier element 10 is cooled.
The cool air supply part 20 includes: a connection pipe 24 connected to the side of the base 100 including the switching valve 22 to supply cold air to the upper portion of the base 100; a nozzle 26 disposed at a distal end of the connection pipe 24; and a discharge fan 28 for supplying cool air to the inside of the base 100. The connection pipe 24 has a double pipe shape and flexibility. That is, the connection pipe 24 is preferably composed of an air supply pipe 24A for supplying cold air to the inside and a bellows-shaped protection pipe 24B made of a general metal material surrounding the outer circumferential surface of the supply pipe 24A.
Thus, when the material of the shaped object 110 to be molded is a food, for example, when a shaped object is molded using chocolate, cold air is supplied to the shaped object 110 to be molded through the nozzle 26 provided at the end of the connection pipe 24, which is regarded as the cold air supply unit 20, thereby completing the molding of the shaped object more finely.
That is, the extrusion part extrudes the powdered or liquid chocolate material and rapidly cools it, and then the chocolate material can be continuously laminated on the extrusion part to complete the molding. At this time, another embodiment of the present invention has a cool air supply part to meet the above-mentioned conditions, thereby providing a condition that can complete the molding more rapidly and finely in a short time.
In addition, the purpose of making the connection tube flexible is to: the connecting pipe can move freely according to the molding position of the molding object, so that cold air can be conveyed to a required accurate position. And, can be according to the fashioned position, the nozzle that possesses in the connecting pipe end is fixed a position accurately to reach the effect of rapid cooling.
