Elasticity in Porous 3D-Printed Polylactic Acid Scaffolds for Biomedical Applications: A Predictive Approach.
Article in Polymers, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Additive manufacturing (AM) is rapidly advancing, particularly in biomedical applications, necessitating a deeper understanding of the mechanical behavior of 3D-printed materials. Structures created using fused deposition modeling (FDM) exhibit anisotropic properties due to fabrication inhomogeneity and material architecture. Finite element modeling (FEM) is commonly used to predict mechanical behavior, though studies on porous structures have not deeply investigated the influence of geometrical features on global mechanical behavior. This study aimed to correlate the mechanical properties of porous polylactic acid scaffolds with different patterns and infill densities, fabricated via AM through the synergies of experimental and computational approaches. Tensile testing and FEM simulations were conducted, revealing differences in elastic modulus and tensile strength based on infill orientation. A sensitivity analysis on the main geometrical features assessed variations in filament dimensions and layer spacing. FEM simulations showed strong agreement with experimental data, validating their predictive capability, with deviations due to minor structural defects and irregularities in the extruded filaments. This study established for the first time the influence of geometrical details on the elastic properties of porous scaffolds, opening up to new tailored design for, but not limited to, biomedical applications.
