Comparison of advantages and disadvantages of injection molding and 3D printing

writer:LI SONG Share

Injection molding is a traditional industrial manufacturing technology. By injecting molten material into the mold, this manufacturing technique can quickly shape your product, and then the material will cool down and reach the final solid shape.

3D printing is a process. You can use a 3D printer to produce parts without creating a mold. You only need a 3D printing model file, and there are many different 3D printing technologies and materials available on the market.

What are the advantages of injection molding?
Injection molding has great advantages, it can be produced in large quantities, and has high precision and perfect repeatability. When using plastic injection molding, you can choose from a variety of materials. There can be thousands of changes for each material through additives, each of which leads to different characteristics. Material weight, cost, flexibility, just for plasticity and possibilities, seem to be endless.

What are the advantages of 3D printing?
The use of 3D printing has many advantages, making it a true complement to traditional manufacturing techniques. First of all, 3D printing is very suitable for product iteration. For a long time, 3D printing has been considered a rapid prototyping technology. This is no longer the case, because it has also become a reliable manufacturing technology. However, quick and easy prototyping is still one of the best advantages provided by this manufacturing technology. When using 3D printing, you can print the project for testing, use the 3D printing modeling software to make all the modifications, and then print again to confirm the changes. The flexibility of this process will help you save time and money, but it can also help you improve your product design.

Using 3D printing also helps avoid material waste. Compared with CNC traditional processing methods, 3D printing can use only the amount of materials required for the entire project, thereby reducing the generation of waste and reducing production costs in disguise. With 3D printing, you can also improve supply chain management to avoid the storage costs of additional inventory.
