3D printing, also known as additive manufacturing, creates physical objects by building them layer by layer from a digital 3D model. In healthcare, this technology is transforming patient care by enabling customized medical devices, anatomical models, surgical guides, and implants.
How Does It Work?
1. Digital Design
Every print starts with a 3D model created using CAD software or medical imaging such as CT or MRI scans.
2. Slicing the Model
The 3D model is converted into hundreds of thin layers using slicing software. The software generates instructions that guide the printer during the printing process.
3. Printing
The printer deposits or solidifies material one layer at a time. Depending on the technology used, the material may be plastic filament, liquid resin, metal powder, or other specialized materials.
4. Post-Processing
Once printing is complete, the part may require cleaning, curing, polishing, sterilization, or quality inspection before it is ready for clinical use.
This is the flow chart of how its done
CT/MRI Scan → 3D Model → Slicing Software → 3D Printer → Finished Medical Model → Clinical Application
