Smaller batches and shorter lead times are just two of the benefits of 3D printing parts in plastic. Here are six reasons to choose polymer additive manufacturing.
1. Low-volume plastic part production without a mold.
2. Easier, faster design iteration and modification.
3. Accelerated lead time.
4. For mass customization or mass personalization.
5. For assembly consolidation.
6. As a replacement for metal.
