As society continues to develop and economic conditions improve, consumers increasingly pursue individuality. Personalized flexible production better meets the diverse needs of people in today's era. Early factories used assembly line production models of the Industrial Age, namely mass-producing homogeneous products. In many factories, the orders decreased from hundreds of thousands of units to tens of thousands or even thousands. Nowadays, market demand quantities are dwindling, necessitating the fulfillment of more personalized customization needs.
