This study investigates the effect of 3D printing speed on mechanical strength parts produced with high-speed PLA. Samples were tested according to ISO 527-1 standard, focusing tensile strength. The results reveal that increasing print from 30 mm/s 500 reduces samples, although difference is minimal and does not affect surface quality when material appropriately selected. Additionally, orientation samples build plate had a significant impact their strength, printed along Y-axis exhibiting better performance. Ironing, which smooths at end print, improved fracture consistency regardless speed. improvement in observed ironed specimens can be attributed bonding layers, reduced porosity, reduction stress concentration points, ultimately contributed more uniform distribution less risk premature failure. Thermal camera images indicated no deviations heat distribution, excluding this factor as cause for inconsistent points. concludes higher speeds offer time energy savings properties, making them suitable prototyping decorative elements, effects should considered applications requiring
