Engineering radar

Selected material

Material average - PETG

Manufacturer average - BambuLab

Legacy Impact radar: 24.243 % 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.

Fixture thermal result

Nearby BlueDOT probe-indicated fixture temperature from a non-standard comparative 3DPIceland method; not ASTM D648, ISO 75, specimen temperature, certified HDT or a manufacturer limit.

Engineering interpretation

Summary: BambuLab Standard Indigo Blue PETG CF Blue has a low engineering profile. 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 Charpy.

Data-driven review: BambuLab Standard Indigo Blue PETG CF Blue 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 4% overall, is missing enough context for the material-family average, and is missing enough context for the manufacturer average. Its strongest engineering signal is Consistency, while Charpy is the main limitation to consider before using it for demanding applications.

Strengths

Best available signal: Consistency at 70/100.

Limitations

Tensile: 21/100. Avoid using this as the primary choice for tensile-loaded parts.
Izod/Charpy impact family: 6/100. Validate impact or shock-loaded components against their application requirements.
Layer adhesion: 16/100. Z-axis performance should be treated with caution.

Engineering trade-offs

Good repeatability does not compensate for low tensile capability in load-bearing designs.
The report should be read as a suitability warning rather than a general-purpose recommendation.

Recommended applications

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.
