Compared with injection molding, 3D printing of plastic parts has the following advantages and disadvantages.

Compared with injection molding and 3D printing of plastic parts

Advantages

1. Strong customizability: 3D printing technology can be customized according to individual needs, so that it can better meet the personalized needs of customers.
2. Fast manufacturing speed: Through 3D printing technology, products can be manufactured faster without the need to manufacture injection molds or set up injection molding processing production lines.
3. High flexibility: Unlike injection molding, 3D printing can manufacture very complex structures, including irregular, hollow or indoor curved structures.
4. Small batch production: Small batch production is particularly suitable for completing the manufacturing process through 3D printing, reducing inventory pressure and not adding additional production costs.
5. Good repeatability: 3D printing technology has high precision and makes repeated manufacturing very easy, and can produce more of the same products.

Disadvantages

1. Low production speed and efficiency: Although 3D printing can manufacture very complex structures, its manufacturing speed is significantly slower than injection molding.
2. Poor quality of finished products: The quality of 3D printed products is much worse than that of injection molding in terms of stability and surface smoothness, and the durability when exposed to the environment is insufficient, so 3D printing technology is generally used in the initial trial stage of a project.
