Abstract

The invention relates to a self-propagating reaction and a 3D printing technology, in particular to a 3D printing method based on a self-propagating reaction. The self-propagating chemical reaction is used in the whole printing process for heat releasing, and an outer heat source is completely or partly not needed. In the printing process, products with needed components and structures are obtained through a self-sustained reaction of fast automatic wave combustion. The printing controllability is good, the speed, the temperature, the conversion rate and the components and the structures of the products in the process are controlled by changing the releasing and transmitting speed of heat. The self-propagating reaction and the traditional 3D printing technology are combined to increase the overall printing speed, the printing period is shortened, a large quality of printed products can be obtained rapidly, and various metal powder materials can be applied. Energy does not need to be supplied continuously once ignition is conducted, compared with laser sintering, cost is lower, efficiency is higher, and equipment is simple and easy to manufacture.

Description

technical field [0001] The present invention relates to self-propagating reaction and 3D printing technology, in particular to a 3D printing method based on self-propagating reaction. Background technique [0002] 3D printer is a machine of rapid prototyping technology. It is a technology based on a digital model file and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. Use the 3D printer to print the model, without the need of traditional cutting machine tools and molds, under the control of the computer, according to the 3D model of the workpiece, through the layered discrete and accumulation process from point to line, from line to surface, from surface to volume, Quickly realize the manufacturing and forming of complex three-dimensional solids. [0003] The British "Economist" magazine believes that 3D printing technology, together with other digital production models, will promote and realize the third industri...
