Engineering score profile
Engineering radar
Selected material
Material average - PETG
Manufacturer average - Thorwell
Legacy Impact radar: 12.127 % of legacy rig capacity. This historical visual reference is the mean corrected Flat/Upright result divided by the matching rig capacity; it is not a modern engineering score.
Izod and Charpy use versioned method references and together form one equally weighted impact family. Overall requires all five families and both calibrated methods; incomplete profiles are not ranked. Legacy Impact and thermal are outside Overall. Missing axes have gaps with no marker or filled polygon; measured zero retains a centre marker.

Engineering interpretation
Summary: Thorwell Standard Carbon Fiber-T PETG CF Black has a low engineering profile. It is without enough material-family average context and without enough manufacturer average context. Its strongest measured axis is Stiffness, while the weakest axis is Charpy.
Data-driven review: Thorwell Standard Carbon Fiber-T PETG CF Black is best understood as a limited-use material that should be validated carefully before functional use. Compared with the current verified dataset, it ranks better than 2% overall, is missing enough context for the material-family average, and is missing enough context for the manufacturer average. Its strongest engineering signal is Stiffness, while Charpy is the main limitation to consider before using it for demanding applications.

Strengths
- Stiffness: 70/100. Stiffness is a relative advantage in this comparison group.
Limitations
- Tensile: 15/100. Avoid using this as the primary choice for tensile-loaded parts.
- Izod/Charpy impact family: 2/100. Validate impact or shock-loaded components against their application requirements.
- Consistency: 64/100. Repeatability may not be the best reason to choose this filament.
- Layer adhesion: 13/100. Z-axis performance should be treated with caution.
Engineering trade-offs
- Good repeatability does not compensate for low tensile capability in load-bearing designs.
- Stiffness is useful for shape stability, but impact tolerance is a separate limitation.
- The report should be read as a suitability warning rather than a general-purpose recommendation.
Recommended applications
- Rigid brackets, fixtures and shape-stable prototypes
- Cosmetic parts, concept models or low-load prototypes
- Avoid high tensile load applications
- Avoid high impact components

Decision guidance
- Use this material mainly for low-load, visual or experimental parts.
- Review the listed alternatives if the application needs stronger overall performance.
- Do not choose it as a tensile-strength benchmark material.
- Validate impact-focused or shock-loaded designs against the measured Izod/Charpy results.

Methodology and limitations
Results are comparative 3DPIceland measurements from home-built test equipment. Thermal is a nearby BlueDOT probe-indicated fixture temperature, not ASTM D648, ISO 75 or specimen temperature. Missing evidence remains n/a. Scores and test results are not recalculated by this publishing layer and do not replace certified manufacturer datasheets or accredited laboratory testing.
