INSTRUCTIONS: [Technical field to which the invention pertains] • This case relates to a two-way spreading and printing device, especially a two-way powdering and printing device and method thereof for a three-dimensional forming mechanism. [Prior Art] The rapid prototyping (RP technology) system is developed based on the concept of building a pyramid layer stacking. The main technical feature is the rapid molding, which can be used without any tools. In the case of fixtures, the design of any complex shape can be quickly and automatically converted into a 3D physical module f, which greatly shortens the development cycle of new products and reduces the cost of research and development, ensuring the time-to-market and new development of new products. The success rate of the product, which provides a complete and convenient product design communication tool between technicians, non-technical personnel such as technicians, decision makers, and product users, thus significantly improving the production market. The competitiveness and rapid response of the enterprise to the market. This force °σ / pre-RP technology developed the use of printing technology: carrier precision positioning technology to produce 3D solid model, its production of square gas layer-layer powder laying Above the vehicle and using a jet-printing technique to print a high-viscosity adhesive liquid to make the glue liquid and powder: solidify, repeating The process layer is stacked and combined. j is a 3D physical mold. However, it is known that the RP printing used in the RP technology can not be sealed when it is not printed. The residual glue will be dried in the print head or the cast maintenance station. 201036803 will cause Subsequent printing is not functional and it is impossible to continue printing to produce high quality 3D products. • The current RP technology is known as rapid prototyping technology, but it does take hours or tens of hours to form, regardless of the size of the part. The size of the item or how to improve the equipment of the rapid prototyping device. In the finished product, when the print head itself is blocked, if it is not immediately determined or perceived, it will result in irreparable time and material waste. In addition, when forming a liquid with a high-viscosity adhesive, the jetting speed of the glue point is as high as 8 m/sec. In this ultra-high-speed spray, when the droplet sticks to the powder, the next side is not the droplet. The sticky nano-sized small powder will rebound and fly, and when the powder is fed or picked up, the powder will fly everywhere when the push powder pile is dropped, and the conventional equipment does not have a quantitative powder feeding mechanism. Pushing the excess powder into the recovery cylinder will cause pollution and energy waste when the powder is dropped. In addition, it is necessary to wait for the molding drying time after each powdering, and wait for several hours to dry after molding, that is, if the forming strength is insufficient or Q Inadvertently, it may damage the finished product. Therefore, it is necessary to make the molded product strong enough to be taken out and the printing positioning accuracy cannot be achieved. Only one-way rapid powdering and printing can be performed, and the total molding time is increased. In addition, when the machine is in standby for a long period of time or the print head is removed, the blade and the seal in the maintenance station may adhere to the glue and cause hardening. Moreover, the conventional technology uses a one-way powder coating and a one-way printing device, and the one-way printing of the printing module firstly supplies powder from the origin to the end point, and then powders from the end point to the origin. Finally, printing from the origin to the end point, the pre-operation time is too long, and the time cannot be fully utilized. 5 201036803 Therefore, how to develop a two-way spreading and printing device and a method thereof which are suitable for a three-dimensional forming mechanism which can improve the above-mentioned conventional techniques, is an urgent problem to be solved.

It is to be understood that the present invention is capable of various modifications in the various aspects of the present invention, and the description and illustration are in the nature of Please refer to the first figure A and the first figure B. The first figure A is a three-dimensional structure diagram of the three-dimensional forming mechanism of the preferred embodiment of the present invention, and the first figure B is a schematic cross-sectional view of the first figure A, such as the first As shown in FIG. A, the three-dimensional forming mechanism 1 of the present invention mainly comprises a printing module 11 , a plurality of temporary storage powder slots, a plurality of powder supply tanks, and a lifting device 14 on a construction base 9 having a bearing platform 91. And a construction slot 15 (as shown in Figure B). Moreover, the three-dimensional forming mechanism of the present invention further has a printing quality detecting mechanism and an image detecting component, and the printing quality detecting mechanism comprises a driven scrollable paper for the printing module to spray on the paper. Printing a pattern, the image detecting component detecting the pattern of the paper to determine whether the printing stamp is blocked; and preventing the printing module from remaining on the printing head when the printing module is not operated The liquid hardened and flying powder containing the glue adheres to the printing head, which leads to the subsequent printing function being poor, and the high-quality three-dimensional object cannot be continuously printed. Therefore, a maintenance device is also arranged in the three-dimensional forming mechanism of the present invention. Furthermore, the three-dimensional forming mechanism of the present invention constructs a liquid three-dimensional object by spraying a liquid containing a glue on the powder, and the construction powder causes a dusty flying working environment during the powdering or printing operation, affecting the above-mentioned devices and components. It works normally. However, the devices and components of the three-dimensional forming mechanism of this case are required to maintain normal operation at any time, and it is necessary to require absolute dustproofness of the entire equipment. Therefore, the three-dimensional forming mechanism of the present invention is further provided with a dustproof device, and the dustproof device includes a transmission. The dust-proof structure of the component, the dust-proof structure of the construction groove, the dust-proof structure of the maintenance device, the dust-proof structure of the working environment, and the dust-proof structure of the powder storage tank are used to prevent the powder contamination caused by the powder-laying and printing operations. Be isolated. In addition, the general three-dimensional forming mechanism is very time-consuming to construct a three-dimensional object. To overcome this shortcoming, the speed of laminating the lamination on the groove must be accelerated, but at room temperature, the liquid containing the glue is sprayed. It is necessary to dry for a period of time. In order to shorten the drying time, the three-dimensional forming mechanism of the present invention is further provided with a heating return air device, which can speed up the drying time, achieve rapid printing and molding time, and can be used as the dustproof protection of the inkjet head. Moreover, in order to achieve the purpose of continuously supplying the liquid containing the glue, the three-dimensional forming mechanism of the present invention further provides a continuous liquid supply device for transferring the liquid containing the glue to one of the printing blocks of the printing module. The long-lasting time is continuously carried out on the construction powder. Hereinafter, the related devices, members, and three-dimensional object forming methods mentioned in the above three-dimensional forming mechanism will be described in detail. Referring to FIG. B, the internal structure of the construction groove 15 is connected to some components of the lifting device 14 and can be up and down and up and down, and the interior of the construction groove 15 has a construction platform 151 for laying the platform 151. The three-dimensional object is stacked and formed in a layered manner, and is connected to the lifting device 14 for positioning. The lifting device 14 is mainly driven by the lifting device 14 to raise the inside of the construction groove 15 201036803. Please refer to the first figure A, and the plurality of powder supply slots may include 2 The powder feeding slots 131 and 132 are mainly disposed on the left and right sides of the three-dimensional forming mechanism 1 and are used to provide the construction powder required for producing the three-dimensional object. For example, the plurality of temporary storage powder slots may include two temporary storage powder slots 121 and 122, which are respectively disposed on the left and right sides of the printing module 11, and are connected to the left and right sides together with the printing module 11 for The powder tank 131 is disposed on the same side as the temporary storage powder tank 121 for providing the construction powder to the temporary storage powder tank 121 for subsequent construction and paving, and the powder supply tank 132 is matched with the temporary storage powder tank 122. On the same side, the construction powder is provided to the temporary storage powder tank 122 for subsequent two-way construction and paving. In this embodiment, the method for implementing the three-dimensional object type operation from the first side to the second side of the printing module 11 is described. The first side represents the left side of the first figure A, and the second side represents the first side. The right side of Figure A, but the actual operation mode is not limited to this. Please refer to the first figure B and the twelfth figure. The operation mode of the three-dimensional forming mechanism 1 of this case is as follows: First, when the left side is supplied with Q powder tank When the 131 is matched with the temporary storage powder tank 121, the powder supply tank 131 will provide the construction powder 16 required to be laid on the entire surface of the construction platform 151 once to the temporary storage powder tank 121 (step S121 and the first figure D). After the powder supply is completed, the printing module 11 will drive the temporary storage powder tank 121 to move from the left side to the right side (step S122), and the construction powder 16 inside the temporary storage powder tank 121 will be laid on the construction platform during the moving process. On the surface of 151 (step S123), until the printing module 11 moves to the right side (as shown in the first figure C), the powder supply tank 132 can be arranged correspondingly with the temporary storage powder tank 122, and the powder supply tank 132 also provides laying on the entire surface of the construction platform 151 once in 201036803 If the powder 16 is to be built into the temporary storage powder tank 122 (step S124), after the powder supply is completed, the printing module 11 will be moved to the left side, and the portion laid on the construction platform 151 by the ink jet printing technology will be used. The build powder 16 is sprayed on. The liquid containing the glue is applied to adhere and solidify the liquid to the construction powder 16 (step S125), and the temporary storage powder tank 122 disposed on the right side of the printing module 11 is subsequently laminated. The powder 16 is constructed on the construction powder 16 which has been subjected to jet printing (step S126), and the printing module 11 is moved to the left side and the powder supply tank 131 is again matched with the temporary storage powder tank 121. The groove 131 will again supply the powder into the temporary storage powder tank 121 (step S127), after which the printing module 11 drives the temporary storage powder tank 121 to move from the left side to the right side, and uses the inkjet printing technology to construct the platform 151. The partially constructed powder 16 is sprayed with a high-viscosity glue liquid to adhere and solidify the glue liquid to the construction powder 16 (step S128). Then, the operating software of the three-dimensional forming mechanism 1 determines whether the three-dimensional object production has been completed. step If the result is YES, the end of production step, the lifting device 14 Q 151 will drive the construction of the platform to rise, to remove excess powder construction 16, for pickup.
