• Difficulties in traditional manufacturing:

(1)Low material utilization rate, heavy product weight and high processing cost.

(2)Part of the structural design is unreasonable, and the product performance is compromised due to the consideration of traditional manufacturing methods.

• Advantages of 3D printing:

(1)Optimized design for product functions to realize geometric shapes that cannot be realized by traditional manufacturing processes.

(2)Lightweight, high effective utilization rate of materials.

(3)Insensitive to product complexity in manufacturing costs.
