Engineering score profile
Engineering radar
Selected material
Material average - PET
Manufacturer average - Siraya Tech
Legacy Impact radar: 22.583 % 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: Siraya Tech Fiberheart Black PET CF Black has a specialized or limited engineering profile. It is above its material-family average by 6,3 points and without enough manufacturer average context. Its strongest measured axis is Stiffness, while the weakest axis is Izod.
Data-driven review: Siraya Tech Fiberheart Black PET CF Black is best understood as a repeatable material for cosmetic, concept and low-load prototype work. Compared with the current verified dataset, it ranks better than 84% overall, is above the material-family average by 6,3 points, and is missing enough context for the manufacturer average. Its strongest engineering signal is Stiffness, while Izod is the main limitation to consider before using it for demanding applications.

Strengths
- Consistency: 81/100. Repeatability is one of the stronger signals in this material profile.
- Izod/Charpy impact family: 19/100. The two-method impact score is competitive against the material-family context.
- Tensile: 35/100. Tensile behavior is competitive against the material-family context.
- Stiffness: 100/100. Stiffness is a relative advantage in this comparison group.
Limitations
- Tensile: 35/100. Avoid using this as the primary choice for tensile-loaded parts.
- Izod/Charpy impact family: 19/100. Validate impact or shock-loaded components against their application requirements.
- 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
- Repeatable print jobs and production-style batches
- Cosmetic parts, concept models or low-load prototypes
- Avoid high impact components

Decision guidance
- Use this material mainly for low-load, visual or experimental parts.
- 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.
