FAQ

Q: How does 3D printing differ from traditional manufacturing?
A: 3D printing builds objects layer by layer from digital designs, allowing for complex geometries and customization, whereas traditional manufacturing often removes material from a solid block or uses molds.

Q: What materials are used in scientific 3D printing?
A: Common materials include plastics (PLA, ABS), metals (titanium, steel), ceramics, and biological substances for bioprinting.

Q: Can 3D printing be used for live tissue?
A: Yes, bioprinters can deposit living cells in scaffolds to create tissue models for research and potential medical applications.

Q: Is 3D printing safe for medical devices?
A: Devices must meet regulatory standards for safety and biocompatibility. Not all printable materials are suitable for medical use.

Q: How does AI improve 3D printing in science?
A: AI optimizes designs, predicts performance, and automates quality control, enabling faster and more reliable scientific outcomes.

Q: What are the limitations of 3D printing in science?
A: Limitations include material constraints, print resolution, device durability, and regulatory hurdles for clinical use.
