Summary
This study evaluated 15 3D printable materials for biomedical imaging accessories. Durable, easily cleaned materials that do not interfere with CT, PET, or optical imaging were identified.
Area of Science:
- Biomedical Engineering
- Materials Science
- Medical Imaging Technology
Background:
- Custom accessories for biomedical imaging (restraint, anesthesia, monitoring) require easy cleaning and must not affect image quality.
- 3D printing offers rapid prototyping for creating specialized imaging tools and accessories.
Purpose of the Study:
- To evaluate 3D printable materials for use in biomedical imaging applications.
- To identify materials that are durable, cleanable, and compatible with various imaging modalities.
Main Methods:
- Fifteen 3D printable materials were assessed.
- Evaluations included radiodensity, optical properties, simulated wear resistance, and repeated cleaning/disinfection capacity.
Main Results:
- Materials were characterized based on their suitability for imaging.
- Specific materials demonstrated durability and ease of cleaning.
- Compatibility with computed tomography (CT), positron emission tomography (PET), and optical imaging was considered.
Conclusions:
- Several 3D printable materials are suitable for creating custom biomedical imaging accessories.
- Selection criteria focused on material durability, cleanability, and minimal interference with imaging modalities.
