Strengths
- Layer adhesion: 61/100. Z-axis bonding is better than the material-family context.
- Consistency: 86/100. Repeatability is one of the stronger signals in this material profile.
- Tensile: 39/100. Tensile behavior is competitive against the material-family context.
- Stiffness: 88/100. Stiffness is a relative advantage in this comparison group.
Limitations
- Tensile: 39/100. Avoid using this as the primary choice for tensile-loaded parts.
- Impact: 12/100. 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.
- Stiffness is useful for shape stability, but impact tolerance is a separate limitation.
Recommended applications
- Rigid brackets, fixtures and shape-stable prototypes
- Parts where Z-axis bonding is important
- Repeatable print jobs and production-style batches
- Cosmetic parts, concept models or low-load prototypes
- Avoid high impact components

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.
