Engineering radar

Selected material

Material average - TPU

Manufacturer average - Siraya Tech

Legacy Impact radar: 61.705 % 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.

Fixture thermal result

111 °C · score 56/100 · method 3dp-thermal-deflection-fixture-v1
Nearby BlueDOT probe-indicated fixture temperature from a non-standard comparative 3DPIceland method; not ASTM D648, ISO 75, specimen temperature, certified HDT or a manufacturer limit.

Engineering interpretation

Summary: Siraya Tech Fiberheart Black TPU 67D GF 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 Consistency, while the weakest axis is Layer Adhesion.

Data-driven review: Siraya Tech Fiberheart Black TPU 67D GF 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: 92/100. Repeatability is one of the stronger signals in this material profile.

Limitations

Tensile: 27/100. Avoid using this as the primary choice for tensile-loaded parts.
Layer adhesion: 25/100. 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

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.
