Engineering score profile
Engineering radar
Selected material
Material average - PLA
Manufacturer average - Landu
Legacy Impact radar: 16.128 % 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: Landu Standard Black PLA Plus Black has a profile awaiting complete scoring evidence. It is without enough material-family average context and without enough manufacturer average context. Its strongest measured axis is Stiffness, while the weakest axis is Layer Adhesion.
Data-driven review: Landu Standard Black PLA Plus Black has incomplete scoring evidence or pending method references. Overall suitability and ranking are unavailable. Available scored axes can be inspected separately; missing scores do not establish weak material performance.

Strengths
- Consistency: 76/100. Repeatability is one of the stronger signals in this material profile.
- Stiffness: 77/100. Stiffness is a relative advantage in this comparison group.
Limitations
- Tensile: 25/100. Avoid using this as the primary choice for tensile-loaded parts.
- Layer adhesion: 18/100. Z-axis performance should be treated with caution.
Engineering trade-offs
- Good repeatability does not compensate for low tensile capability in load-bearing designs.
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

Decision guidance
- Overall suitability is unavailable until the required measurements and method references are complete.
- Do not choose it as a tensile-strength benchmark material.

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.
