Problems solved by technology

[0004] However, the problem of molding quality of 3D printed products has not been effectively solved, especially the poor bonding quality of products will reduce its stress strength, making the strength of printed products lower than that of traditional processing (such as ordinary injection molding, etc.) overall strength of the product
[0007] Cyanoacrylate reactive adhesives belong to instant adhesives, which seem to meet the above requirements, but in practice, it is found that the process of direct addition is very strict, because its curing on the polymer melt still requires For a certain period of time, this makes it necessary to strictly control its application amount and the time gap of the printing process. Although it has been found that a more appropriate addition can indeed improve the bonding quality, it will also cause adhesion due to a slight deviation in the application amount or printing interval. Therefore, in order to directly apply the adhesive more conveniently, a more perfect method is still needed

Embodiment 1

[0030] First, the printing filament is manufactured. Weigh raw materials according to the following weights: ABS: 990g, woody powdered activated carbon: 10g. After mixing ABS and wood powdery activated carbon, melt it in an ordinary plastic extruder, pass it through a head with a diameter of 3mm, and stretch it properly to obtain a wire with a diameter of 3mm. The melt temperature during the extrusion process is 190°C;

[0031] Secondly, compile the 3D model of ordinary tensile splines in the computer, select the layer thickness as 0.3mm in the control software of the 3D printer to divide it into 10 layers, and the software automatically calculates the printing path of each layer, except for the uppermost Except for the bottom layer, the printing direction between the other two layers is exactly opposite, thus forming a staggered printing path;

Abstract

The invention discloses a method for improving the bonding quality of polymer three-dimensional printing products by using an instant adhesive, which comprises the following steps: (1) mixing polymer raw materials added with an adsorbent evenly and extruding printing filaments through ordinary plastics (2) putting the wire material prepared in step (1) into the polymer three-dimensional printer, layering according to the three-dimensional model to be printed, and performing three-dimensional printing after obtaining the three-dimensional processing data of each layer; (3) printing During the process, the instant adhesive is evenly added to one or several layers of the object to be printed. Adding the instant adhesive in the present invention can solve the problem of more porosity inside the three-dimensional printing product, so the method can improve the bonding quality and force strength between the two layers. From the effect point of view, the printed The bonding strength of the product can exceed more than 30% of the bonding strength of ordinary three-dimensional printing products, and can basically reach the tensile strength of ordinary injection parts.

Description

technical field [0001] The invention relates to a method for improving the bonding quality of polymer three-dimensional printing products by using an instant adhesive, and belongs to the technical field of three-dimensional printing and manufacturing of polymer materials. Background technique [0002] 3D printing technology is a kind of additive manufacturing technology, which is completely different from the traditional method in terms of manufacturing mode. It is based on the idea of ​​discrete / accumulation, and the CAD 3D model of the product is sliced ​​in layers along a certain direction through computer software, and each layer is obtained. The processing information of the cross-sectional profile is superimposed layer by layer by the 3D printer, so that prototypes or parts with certain functions can be processed quickly and accurately. As one of the rapid prototyping technologies, 3D printing technology can quickly obtain product prototypes, quickly respond to market ...
