Strengths & Limitations

Strengths

  • +Provides quantitative data on surface property changes.
  • +Uses standard 3D printing technology and materials.

Limitations

The specific mechanical properties (tensile strength, impact resistance) were not the primary focus, and the long-term effects of carbon fiber on print head wear were not investigated.

Reliability & validity

The use of multiple samples (3 of each type) and standardized measurement techniques (optical microscope, FT-IR) contributes to the reliability of the findings. The direct comparison between PETG and PETG/Carbon under identical printing conditions enhances validity.

Think critically

How might the increased microhardness and slightly decreased Shore hardness D of the carbon fiber composite affect its suitability for different types of functional applications?
