Selected material

Material average - PETG

Manufacturer average - Coex 3D

Legacy Impact radar: 13.872 % 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: Coex 3D Standard Banana Yellow PETG Yellow has a specialized or limited engineering profile. It is without enough material-family average context and below its manufacturer average by 6,6 points. Its strongest measured axis is Consistency, while the weakest axis is Charpy.

Data-driven review: Coex 3D Standard Banana Yellow PETG Yellow 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 26% overall, is missing enough context for the material-family average, and is below the manufacturer average by 6,6 points. Its strongest engineering signal is Consistency, while Charpy is the main limitation to consider before using it for demanding applications.

Dataset position

Better than 26%

60 / 80

Strengths

Layer adhesion: 38/100. Z-axis bonding is better than the material-family context.

Limitations

Tensile: 30/100. 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.
Layer adhesion: 38/100. 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.
