Summary
3D printing using fused deposition modeling (FDM) technology can accurately create patient-specific anatomical models from CT scan data. These models offer significant potential for surgical planning, medical training, and patient communication.
Area of Science:
- Medical Imaging
- Biomedical Engineering
- Additive Manufacturing
Background:
- Computed Tomography (CT) scans generate detailed anatomical data.
- 3D printing offers a method for creating physical models from digital data.
- Fused Deposition Modeling (FDM) is an accessible 3D printing technology.
Purpose of the Study:
- To assess the feasibility of manufacturing human anatomical models using FDM 3D printing.
- To evaluate the accuracy of FDM-printed anatomical models derived from CT data.
- To explore the applications of FDM-printed anatomical models in the medical field.
Main Methods:
- DICOM CT scan data was converted to Standard Triangle Language (STL) format using InVesalius software.
- A patient's skull CT scan data was used as a case study.
- The anatomical model was fabricated using a desktop FDM 3D printer with Acrylonitrile Butadiene Styrene (ABS) plastic.
Main Results:
- Accurate 3D anatomical models were successfully fabricated from CT scan data.
- The FDM 3D printing process yielded a high-fidelity replica of the patient's skull.
- The physical skull model demonstrated the capability of FDM technology for precise anatomical representation.
Conclusions:
- FDM 3D printing technology is suitable for producing accurate anatomical models.
- These models can enhance preoperative surgical planning, medical training, and implant design.
- 3D-printed anatomical models can improve communication between healthcare professionals and patients.
