Auxiliary heating device and control method for 3D printer

Abstract

The invention relates to the field of three-dimensional printing machines, in particular to auxiliary heating equipment of a 3d printing machine and a control method of the auxiliary heating equipment. The auxiliary heating equipment comprises three-dimensional printing equipment and a lifting platform and further comprises a working platform, a programmable numerical control heating controller and an infrared thermal imager. The working platform is of a cuboid frame structure and is made of a high-temperature resisting material. Each side frame of the working platform is provided with array heating elements. The array heating elements face the inner side of the working platform. The lifting platform of the three-dimensional printing equipment is provided with a height senor for detectingreal-time heights. According to the auxiliary heating equipment, the heating compensation manner of the array heating elements such as infrared heating bulbs used for producing heat radiation is usedfor replacing a traditional heating wire and air circulating heating manner, the energy radiation can be precisely controlled, the efficiency and precision of control over the temperature interval areimproved, meanwhile, parts can be precisely heated and subjected to heat preservation, and moreover a plurality of different heating compensation control manners are provided.

Description

technical field [0001] The invention relates to the field of three-dimensional printers, in particular to an auxiliary heating device for a 3D printer and a control method thereof. Background technique [0002] 3D printing technology, also known as additive manufacturing technology, uses a 3D digital model as a template, and by using an energy source to increase energy, the materials are bonded together physically or chemically, and the processing of physical objects is constructed layer by layer. technology. Its characteristic is that the object can realize the requirements of being manufactured only by adding materials without going through the traditional cutting process. [0003] The application process of 3D printing is as follows: the object to be constructed is first constructed in the computer through software modeling or hardware scanning to construct a corresponding 3D model and converted into a grid model that can be recognized by the 3D printing software, and th...

Problems solved by technology

However, since the heating of the heating wire is to heat and keep the processing space of the part through the heating method of electric current, the heating speed is relatively slow and the efficiency is relatively low.

Moreover, the accuracy of temperature control and position control by means of heating wire heating is not high, and it is difficult to effectively reduce the influence of the outside world on the construction process
