Laser Sintering of Polyamide 12 Nanocomposites: Combined Effects of Plasma Treatment and Laser Energy.
Article in 3D printing and additive manufacturing, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The current research studied the influence of plasma surface modification on the morphological and mechanical properties of 3D printed polyamide 12 composites. These composites were produced via laser sintering at three laser energies, 13, 17, and 21 W. Thus, the influence of the laser energies on the nanocomposites' characteristics was also considered. The surface characteristics of the reinforcing materials, untreated and plasma-treated organically modified nanoclay, were characterized using Scanning electron microscopy (SEM) and X-ray diffraction. Furthermore, SEM was also utilized to investigate the fractured surfaces of 3D printed parts made from untreated and plasma-treated nanoclay/polyamide 12 composites after testing for measuring tensile properties (ultimate stress, strain, and elastic modulus). Based on SEM observations, agglomerated sheeted structures were observed in untreated nanoclay. However, these were relatively avoided after plasma treatment, and a more uniform distribution of nanoclay layers on polyamide 12 was observed compared with the untreated ones. This resulted in an improved elastic modulus of plasma-treated nanoclay/polyamide 12 nanocomposites when compared with these results for pure polyamide 12 and untreated nanoclay/polyamide 12 nanocomposites. These results, therefore, provide evidence of a successful combination of laser sintering and plasma treatment.
