Description

How to make tasteful 3D printed products

The present invention relates to a 3D printing method that can directly produce flavor on a 3D printing product.

The 3D printing technology generally used at present is an emerging technology. Because of its wide range of printing products, from small to components, to large mechanical models, etc., it can be achieved through 3D printing technology. Due to the 3D printing technology, a 3D printer is used to melt the wires and then print them layer by layer to produce 3D objects. However, the wire structure of the 3D printing mentioned above only has a change in color when used, and it also has a bad smell of plastic, so it is easy to pollute the air during the printing process. Moreover, the produced 3D objects have poor taste and are difficult to be accepted and liked by the public, so there are problems in use.

Therefore, there is a new patent case No. M493477 "3D printing wire structure improvement" announced on January 11, 104 of the Republic of China, which discloses: a resin layer, an additive layer, a color layer and a fragrance layer, resin The layer is provided on one side for the combination of the auxiliary layer, and the color layer is combined on one side of the auxiliary layer, and the color layer is provided for the combination of the fragrance layer on one side. With the above structure, the auxiliary layer enhances the resin layer The combination and adaptability between the color layer and the fragrance layer, and the color layer makes the additive layer produce color, while the fragrance layer provides fragrance. In this way, the whole (printing wire) will have color and fragrance, and 3D After printing, the finished product still retains its fragrance, achieving the purpose of printing filaments and finished products with fragrance and not easy to decay.

The previous patent application is to combine a fragrance layer on the wire, so that the 3D object manufactured can have fragrance after printing. However, since the fragrance layer must be separately remanufactured and combined when the wire is manufactured, the manufacturing process is complicated and time-consuming and cost-consuming, so it is not ideal for use.

Therefore, there is a new patent case No. M525271 "Structural Improvement of the Nozzle of 3D Printing Device" announced by the Republic of China on July 11, 105, which discloses: a feeding module suitable for supplying a wire to the feeding mold In the throat pipe below the group, and the outside of the throat pipe is provided with a heating module, the wire sent to the inside of the throat pipe is heated and melted to form a molten wire, and then the printing nozzle arranged at the end of the throat pipe And a scent module arranged near the supply module, after the printing nozzle sprays the molten wire for a specific time, the scent module sprays a fragrance material on the molten wire, Make the printed object scented, so that the object is improved in terms of functionality.

Since the fragrance material of the previous patent is driven by a drive motor, the fragrance material is delivered to the spray hole through the pipeline for spraying. If the spraying pressure of the drive motor is too small, it is easy to volatilize the aroma material in the air; if the spraying pressure is too high, it will destroy the surface structure of the molten layer that has been printed on the wire. Moreover, the surface force of the molten layer close to the spray hole will be too large, and the surface force of the molten layer far away from the spray hole will be too small. Therefore, the spraying method will cause problems of uneven pressure and force.

In view of this, in view of the current 3D printing methods that produce flavors on products, they have the above-mentioned shortcomings. Therefore, the present invention provides a method for making a flavored 3D printed product, which includes: A. A 3D printer performs a 3D printing process for a product; B. When the product is 3D printed to a filling size , Suspend the 3D printing process, and make the product form at least one open filling space; C. A fragrance is embedded in the filling space; D. After the fragrance is placed, the 3D printing procedure is continued until the 3D printing of the product is completed.

Before performing the 3D printing procedure of step A, first obtain the actual size data of the product, and then input the data into the 3D printer.

In the above step C, the fragrance is placed in the filling space manually or automatically.

The above-mentioned aromatic substance is one of a spice, a flavor, a perfume, a coffee powder, and a couma, or any combination thereof.

A step C1 is added between the above step C and step D. After inserting the fragrance, continue to execute the 3D printing procedure, and repeat the above step B and step C each more than once.

In step C1, step B is repeated for the first time, so that the product is 3D printed to another preset filling size, then the 3D printing process is stopped, and the product is formed with another open filling Space, and then repeat step C for the first time, insert the fragrance in the other filling space, and then continue to perform the 3D printing process after the fragrance is placed, so as to completely seal the other filling space.

The above technical features have the following advantages:

1. During the 3D printing process, the fragrance is directly put into the product, so that the fragrance of the fragrance can be emitted through the pores between the layers of the product, thereby saving manufacturing costs and man-hours.

2. During the 3D printing process of the product, more than two filling spaces can be formed at the same time, so that more aromas can be placed and the concentration of the taste can be adjusted, so as to be suitable for 3D printing of large-volume products manufacture.

3. During the 3D printing process of the product, multiple filling spaces can be formed repeatedly, so that more aromas can be placed and the concentration of taste can be adjusted for 3D printing of long size Manufacturing.
