Combined line printing method and device for three-dimensional line printing objects

Abstract

The invention discloses combined line printing method and device for three-dimensional line printing objects. A plurality of small-size three-dimensional line printing models are organically combined within the line printing size range of a three-dimensional line printing machine; meanwhile, line printing is carried out by virtue of the three-dimensional line printing machine; and the small-size three-dimensional line printing models are dismantled into a plurality of small-size three-dimensional line printing objects, so that an external support component of the single small-size three-dimensional line printing model during the line printing process can be reduced; and the line printing resources such as line printing consumables and line printing time are reduced. The plurality of three-dimensional line printing models which are suitable for being combined within the line printing size range of the three-dimensional line printing machine are subjected to line printing by the three-dimensional line printing machine, so that the accuracy is easy to control; and the line printing quality of the dismantled small-size three-dimensional line printing objects which are subjected to subsequent line printing is improved.

Description

technical field [0001] The invention relates to printing technology, in particular to a combined printing method and device for three-dimensional printing objects. Background technique [0002] 3D printing is a form of additive manufacturing technology in which 3D printed objects are created by a 3D printer through successive physical layers. Compared with other additive manufacturing technologies, the three-dimensional printing machine has the advantages of fast speed, low price and high usability. A three-dimensional printing machine is a device that can print out real three-dimensional objects. It is functionally the same as the laser forming technology. It adopts layered processing and superposition forming, that is, the three-dimensional printing object is generated by adding materials layer by layer, which is different from the traditional removal Material processing techniques are completely different. It is called a three-dimensional printing machine because it ref...

Problems solved by technology

However, if the size of a 3D printing model is much smaller than the printing size of the 3D printing machine, the printing resources of the 3D printing machine such as time, printing consumables and electric energy are wasted when printing, and When a 3D printing machine prints a small-sized 3D printing model, it is also difficult to control the accuracy, which reduces the printing quality of the obtained small-sized 3D printing object

Furthermore, since the outline of the 3D printing model varies widely, it may be necessary to generate additional external support parts to achieve complete printing, especially for small-sized 3D printing models, which will generate a large number of useless external support parts , adding printing resources such as printing consumables and printing time
