Influence of Print Speed on the Mechanical Performance of 3D-Printed Bio-Polymer Polylactic Acid

Materials, Journal Year: 2025, Volume and Issue: 18(8), P. 1765 - 1765

Published: April 11, 2025

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

The SADRA Algorithm as a Framework for Sustainable Innovation: A Review of Case Studies on 3D‐Printed Reinforced Concrete Beam and Fiber‐Reinforced Concrete

Engineering Reports, Journal Year: 2025, Volume and Issue: 7(5)

Published: May 1, 2025

ABSTRACT The absence of a structured and evolutionary approach in civil engineering research often leads to fragmented innovations limited progress. This study introduces the SADRA Algorithm, philosophical practical framework inspired by Mulla Sadra's concept substantial motion, which emphasizes continuous development refinement projects. effectiveness this algorithm is demonstrated through two comparative case studies: 3D‐Printed Reinforced Concrete Beams Fiber‐Reinforced Concrete. In 3D printing case, an sequence projects shows transition from ineffective hyperboloid shell structures (which reduced compressive tensile strength) optimized truss patterns like Warren Howe trusses, improved flexural strength over 14%. Further refinements led print geometry placement, such as honeycomb infill at 10 mm beam's bottom, enhanced 25%. Each project built upon previous insights, illustrating SADRA's principle iterative contrast, fiber‐reinforced concrete studies (e.g., basalt steel fiber integration) yielded isolated findings. For instance, while 0.5%–1.2% strength, fibers increased ductility performance, lack methodological continuity hindered broader evolution. primary conclusion that Algorithm fosters sustainable innovation enabling project‐based evolution, offering transformative methodology for design, materials development, management.
