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

Measured strengths

Consistency: 82/100. Repeatability is one of the stronger signals in this material profile.
Izod/Charpy impact family: 24/100. The two-method impact score is competitive against the material-family context.
Stiffness: 82/100. Stiffness is a relative advantage in this comparison group.

Limitations

Tensile: 20/100. Avoid using this as the primary choice for tensile-loaded parts.
Izod/Charpy impact family: 24/100. Validate impact or shock-loaded components against their application requirements.
Layer adhesion: 15/100. 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.

Print workflow checks

Confirm nozzle temperature, bed temperature, speed, cooling and drying requirements from the manufacturer profile or spool label.
Print a small validation part before committing to a long, costly or safety-relevant print.
Orient the part so the governing load does not rely on an unverified or weak engineering axis.
Layer-adhesion evidence is weak; avoid critical Z-axis loading without additional validation.

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.

Score policy engineering-score-v70-1: Overall requires tensile, stiffness, consistency, layer adhesion and the Izod/Charpy impact family, each with equal weight. Both impact methods and configured versioned references are required. Missing results and unconfigured scores remain n/a. Legacy Impact is historical only; thermal remains separate. Engineering-axis counts describe displayed evidence, not Overall completeness.
