Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • FFF is recognized as one of the most cost-effective AM techniques, requiring lower energy levels, minimizing material waste, and being effective in manufacturing time.

    “FFF is recognized as one of the most cost-effective AM techniques, requiring lower energy levels compared to other AM methods, minimizing the waste of materials, and being very effective in terms of manufacturing time [175-177].”
  • Molded PEEK has a tensile strength of 98 MPa (at yield).

    “In comparison, the tensile strength of molded PEEK is 98 MPa (at yield).”
  • The reduction in tensile strength from horizontal/0° to vertical/90° PEEK samples is more than 87%.

    “which represents a reduction of more than 87% from horizontal/0 ◦ to vertical/90 ◦ samples.”
  • PEEK samples with build orientations/raster angles horizontal/0°, horizontal/90°, and vertical/90° had tensile strengths of 82.58±1.03 MPa (at yield), 72.88±1.92 MPa (at break), and 9.99±0.94 MPa (at break), respectively.

    “It was found that the tensile strength of the samples with building orientations and raster angles of horizontal/0 ◦ , horizontal/90 ◦ , and vertical/90 ◦ is 82 . 58 ± 1 . 03 MPa (at yield), 72 . 88 ± 1 . 92 MPa (at break), and 9 . 99 ± 0 . 94 MPa (at break), respectively”
  • FFF parts, particularly PEEK, exhibit significant anisotropy: strength in the X-Y plane is usually acceptable, but strength in the Z direction is lower.

    “One remaining challenge in the FFF of materials, particularly PEEK, is the significant anisotropy in different directions. While the strength in the plane parallel to the layers (X-Y plane) is usually acceptable, parts exhibit lower strength levels in the direction perpendicular to the layers (Z direction) [118,175,202].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
