Problems solved by technology

[0005] The object of the present invention is to provide a method for recovering and reusing the heat of lasers used in dual-laser printing, so as to solve the problem in the above-mentioned background technology that existing printers need to use The inside of the device is heated so that the device is at a constant temperature for efficient printing, but during the laser printing process, the heat is radiated to the unprinted powder, and when the parts are finally taken out, they are recycled at one time for reprinting, resulting in laser printing. The problem of heat loss from the

Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] see Figure 1-10 , the present invention provides a technical solution: a method for recovering and reusing heat from lasers for dual-laser printing, and the specific implementation steps of the method:

[0037] Step 1: First heat the incubator to keep the temperature of the incubator constant;

[0038] Step 2: Start the printing equipment for laser printing, and spray the printing layer by layer until the end;

[0039] Step 3: Start the circulation device...

Abstract

The invention discloses a laser heat recycling method for double-laser printing in the technical field of laser printing. The method comprises the specific implementation steps that firstly, a heat preservation box is heated, and the temperature of the heat preservation box is constant; printing equipment is started for laser printing, and layer-by-layer spraying printing is stopped; and a circulating device is started to recycle a printing high-temperature printing medium for reprinting. The problems that when an existing printer is used, the interior of equipment needs to be heated, the equipment is located at the constant temperature for efficient printing, but in the laser printing process, heat on unprinted powder is radiated, when parts are finally taken out, the parts are recycled at a time for reprinting, and consequently heat losses of the laser printer are caused are solved.

Description

technical field [0001] The invention relates to the technical field of laser printing, in particular to a method for recovering and reusing heat from lasers used in dual laser printing. Background technique [0002] Laser 3D printing technology is one of the emerging technologies. It is the laser 3D printing equipment for high-precision metal parts with leading efficiency and the largest size of printed parts in the world; On the level that needs to be increased, add powder with a nozzle (or other means), melt the powder with a laser heat source, and obtain a stacked cladding layer after the powder is melted and cooled, and several thin layers are accumulated to form a three-dimensional entity, which is 3D printing. Basic idea: In the printing process of the existing equipment, the layered printing method is adopted, and a layer is printed, and a layer of printing powder is sprayed. After the printing is completed, the height of the powder is basically the same as the height...
