• Difficulties in traditional manufacturing:

(1)Few quantity, many design schemes, need to open the mold for proofing, high cost.

(2)Some samples have complex structures and it is difficult to open the mold.

• Advantages of 3D printing:

(1)No mold opening is required, which avoids the risk and cost of mold opening when customers require proofing in the early order negotiation stage.

(2)Quick proofing improves the ability to receive orders for complex products and small orders.

(3)Increase the added value of products and help expand new markets.
