Strengths
- Layer adhesion: 47/100. Z-axis bonding is better than the material-family context.
- Consistency: 81/100. Repeatability is one of the stronger signals in this material profile.
Limitations
- Tensile: 30/100. Avoid using this as the primary choice for tensile-loaded parts.
- Impact: 14/100. Avoid high impact or shock-loaded components without additional validation.
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
- 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 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.
- Avoid selecting it for impact-focused testing or shock-loaded designs.

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.
