Engineering score profile
Engineering radar
Selected material
Material average - PETG
Manufacturer average - BambuLab
Legacy Impact radar: 11.551 % 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: BambuLab Basic Gray PETG Gray has a profile awaiting complete scoring evidence. It is without enough material-family average context and without enough manufacturer average context. Its strongest measured axis is Consistency, while the weakest axis is Thermal.
Data-driven review: BambuLab Basic Gray PETG Gray has incomplete scoring evidence or pending method references. Overall suitability and ranking are unavailable. Available scored axes can be inspected separately; missing scores do not establish weak material performance.

Strengths
- Consistency: 74/100. Repeatability is one of the stronger signals in this material profile.
- Tensile: 34/100. Tensile behavior is competitive against the material-family context.
- Stiffness: 68/100. Stiffness is a relative advantage in this comparison group.
Limitations
- Tensile: 34/100. Avoid using this as the primary choice for tensile-loaded parts.
- Layer adhesion: 35/100. Z-axis performance should be treated with caution.
Engineering trade-offs
- Good repeatability does not compensate for low tensile capability in load-bearing designs.
Recommended applications
- Repeatable print jobs and production-style batches
- Cosmetic parts, concept models or low-load prototypes
- Avoid high tensile load applications

Decision guidance
- Overall suitability is unavailable until the required measurements and method references are complete.
- Do not choose it as a tensile-strength benchmark material.

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.
