Selected material

Material average - PLA

Manufacturer average - Coex 3D

Legacy Impact radar: 12.103 % 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 Prime Scarlet Red PLA Red has a specialized or limited engineering profile. It is without enough material-family average context and above its manufacturer average by 4,7 points. Its strongest measured axis is Stiffness, while the weakest axis is Charpy.

Data-driven review: Coex 3D Prime Scarlet Red PLA Red 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 90% overall, is missing enough context for the material-family average, and is above the manufacturer average by 4,7 points. Its strongest engineering signal is Stiffness, while Charpy is the main limitation to consider before using it for demanding applications.

Charpy

Dataset position

Better than 90%

9 / 80

Strengths

Consistency: 88/100. Repeatability is one of the stronger signals in this material profile.
Stiffness: 100/100. Stiffness is a relative advantage in this comparison group.

Limitations

Tensile: 34/100. Avoid using this as the primary choice for tensile-loaded parts.
Izod/Charpy impact family: 4/100. Validate impact or shock-loaded components against their application requirements.
Layer adhesion: 32/100. 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.

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 tensile load applications
Avoid high impact components

Decision guidance

Use this material for moderate requirements after checking the weakest axis.
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.
