This article presents the effects of thermal annealing at elevated temperatures (> glass transition temperature Tg) on the performance of polymer parts via material extrusion 3D printing. Both semi-crystalline and amorphous filaments were used. As-printed parts were designed to be amorphous and then ...
Fused filament fabrication (FFF) is the most popular additive manufacturing method, with which it is possible to obtain highly complex three-dimensional parts without wasting materials. In order to improve the mechanical properties of 3D printed materials, literature suggests the thermal annealing process...

In this work, the AlSi10Mg alloy samples were printed using a selective laser melting process and subsequently subjected to annealing treatment at 280 °C, 300 °C and 320 °C for durations of 2, 3 and 4 h with a heat input rate of 5 °C/min, 10 °C/min and 15 °C/min ...
3D printingFDMPLAannealingCharpy testThis study conducts an experimental exploration and thorough analysis of the influence of annealing on the impact resistance of PLA 3D-printed components. The investigation extends its scope to encompass the influence of printing parameters, specifically la...
Process parameters have a significant impact on the mechanical strength of 3D-printed parts. In this work, the effect of process variables such as infill volume, pattern, layer height, nozzle temperature, and print speed on tensile and compressive strength of polylactic acid samples are investigated...
While 3D printing, polymer filaments heat up quickly before being extruded and cooled down quickly. Polymers have poor thermal conductivity, so the heating and cooling cause unevenness, which then results in internal stress on the printed parts due to the rapidity of the heating and cooling. The...
The measurement also showed that the porosity could significantly vary within a single printed part. This observation highlights the importance of repeated measurements from various parts of the sample (not only more images from a particular cross-section) for the reliable evaluation of the porosity ...
Differential Scanning Calorimetry supported these findings, showing increased crystallinity in PLA, thus highlighting the significant impact of optimized thermal annealing on enhancing 3D-printed PLA parts.doi:10.1016/j.polymertesting.2025.108735alar Kahya...
