3D printing offers rapid prototyping, enabling quick design validation, customization, and reduced lead times. It supports complex and intricate geometries, reducing assembly requirements. Material waste is minimized, making it more environmentally friendly. Additionally, it is useful for creating patient-specific medical implants and prosthetics.

3D printing has constraints related to material options, with limited strength compared to traditional manufacturing. Post-processing may be required for certain finishes. It can be slower and more expensive for large-scale production. Intellectual property concerns can arise as digital files are easily shared.
