Embodiment Construction

[0039] In this example, if figure 2 As shown, a 3D printing batch control method considering printing quality is applied to a 3D printing manufacturing system composed of m printing task models 1, m task queues 2, and 3D printers with a capacity of N, and The types of consumables for each printing task model are the same; the capacity of the 3D printer group 3 is determined by the size of the printing platform.

[0040] Record the bottom surface size of the i-th printing task model as o i ;The size of the bottom surface of the print task model is determined by the size of the smallest enclosing rectangle of the model's horizontal projection shape; set the queue capacity of the i-th task queue as C i , and the i-th printing task model is stored in the i-th task queue;

[0041] Suppose the length c of the i-th task queue i is the state of the i-th task queue, then let the state c of the i-th task queue i Belonging to the state space Φ i ={0,1,2,...,C i}, i=1,2,...,m; then...

Abstract

The invention discloses a 3D printing batch control method considering printing quality, wherein the method includes the steps: 1, a 3D printing and manufacturing system for batch printing of printingtask models is proposed; 2, the 3D printing and manufacturing process randomly reached by the printing task models is described as a semi-Markov decision process; 3, a batch selection action and a printing parameter layer height are used as system actions; and 4, the 3D printing and manufacturing system is optimized on line by a Q learning algorithm. By taking the batch action and the printing parameter layer height as the system actions, the 3D printing and manufacturing system considering the printing quality can be optimized and controlled effectively on line, the quality of the product and the utilization rate of printing resources can be improved, and the waste of the inventory space is reduced.

Description

technical field [0001] The invention belongs to the technical field of production scheduling, and specifically relates to a 3D printing batch control method considering printing quality. Background technique [0002] Scheduling plays an important role in most manufacturing systems and information processing environments. In the manufacturing industry, a reasonable scheduling plan can greatly improve production efficiency and resource utilization, save production costs, thereby enhancing the competitiveness of enterprises and promoting the development of manufacturing. In recent years, with the development of 3D printing technology, 3D printing equipment has gradually entered personal life. 3D printing technology is to obtain a three-dimensional solid model by printing layer by layer, and some preparatory and auxiliary actions are required during the printing process. For example, when printing with FDM fused deposition modeling technology, the nozzle is preheated and the p...
