Special Issue Information

Dear Colleagues,

Thermoplastic and thermosetting polymeric materials are widely used in various fields due to their extraordinary versatility, processability and applicability. Polymers are characterised by different molecular weights and unique chemical structures that influence physical, thermal and mechanical behaviour. They are applied in sectors such as medicine, packaging, electronics, automotive and aerospace. Polymeric additives such as latex appear to be a promising type of component that can significantly change the properties of concrete and mortar.

To investigate this further, we are launching a Special Issue of Polymers entitled "Mechanical Behaviour of Polymeric-Based Systems Used in Engineering Applications, 2nd Edition". This volume aims to collect contributions on recent advances in the form of research papers, communications, and review articles, exploring the mechanical and rheological properties of polymeric materials and emphasising the scientific and academic cooperation and guidance needed for the development/design and application of polymer-based materials.

This study examines the effect of elevated printing speeds (100–600 mm/s) on the dimensional accuracy and tensile strength of PLA components fabricated via fused deposition modeling (FDM). To isolate the influence of printing speed, all other parameters were kept constant, and two filament variants—natural (unpigmented) and black PLA—were analyzed. ISO 527-2 type 1A specimens were produced and tested for dimensional deviations and ultimate tensile strength (UTS). The results indicate that printing speed has a marked impact on both geometric precision and mechanical performance. The optimal speed of 300 mm/s provided the best compromise between dimensional accuracy and tensile strength for both filaments. At speeds below 300 mm/s, under-extrusion caused weak layer bonding and air gaps, while speeds above 300 mm/s led to over-extrusion and structural defects due to thermal stress and rapid cooling. Black PLA yielded better dimensional accuracy at higher speeds, with cross-sectional deviations between 2.76% and 5.33%, while natural PLA showed larger deviations of up to 8.63%. However, natural PLA exhibited superior tensile strength, reaching up to 46.59 MPa, with black PLA showing up to 13.16% lower UTS values. The findings emphasize the importance of speed tuning and material selection for achieving high-quality, reliable, and efficient FDM prints. Full article
