This study assessed new polycarbonate materials for 3D printing, finding talc filler affects properties. Material moisture content significantly impacts processing and implant stability outcomes.

Area of Science:

Materials Science
Biomedical Engineering
Additive Manufacturing

Background:

Polycarbonate-based materials are increasingly used in 3D printing for various applications.
Optimizing material properties is crucial for successful fabrication and performance, especially for biomedical implants.
Understanding the influence of fillers and processing conditions is key to material development.

Purpose of the Study:

To qualitatively assess new polycarbonate materials with talc fillers for 3D printing applications.
To evaluate the processability, geometric modification (drilling), and implant stability of these novel materials.
To determine the impact of talc content and moisture on material performance.

Main Methods:

Microscopic visual inspection of talc-doped polycarbonate filaments.

Keywords:

Fabrication of calibration and test models using fused filament fabrication (FFF).

Assessment of drilling susceptibility, shavings behavior, temperature changes during drilling, and implant stability quotient (ISQ).

Main Results:

Talc filler content significantly influences the composite material properties.
The use of a compatibilizer (polyol) was necessary due to talc's properties.
Differences in processing and ISQ were observed between commercial, dried, and undried materials, highlighting the importance of moisture control.

Conclusions:

The amount of talc filler critically affects the performance of polycarbonate composites for 3D printing.
Controlling moisture content during processing is essential for achieving desired material properties and implant stability.
These findings provide valuable insights for developing advanced polycarbonate materials for additive manufacturing, particularly in biomedical fields.
