Summary
Stereolithography (SLA) 3D printing is a form of additive manufacturing which employs ultraviolet (UV) lasers to selectively cure liquid photopolymer resin into solid layers, producing highly detailed and precise components (Aerosport Additive, n.d.). In civil engineering, SLA technology is increasingly utilized for architectural modeling, structural prototyping, and customized component fabrication. Engineers leverage SLA printing to create scaled building models, bridges, and façade elements, achieving resolutions as fine as 25 microns (Wu, Wang, & Wang, 2016). SLA systems consist of a UV laser, a resin vat, and a build platform, which work together to achieve layer-by-layer curing. Advancements in engineering-grade resins now offer enhanced mechanical properties such as increased tensile strength, thermal stability, and chemical resistance, making SLA prototypes viable for functional testing (Goodfish Group, n.d.). Furthermore, SLA’s ability to fabricate intricate internal structures, including lattice frameworks, supports lightweight and optimized designs, a key factor in sustainable construction (All3DP, n.d.). While historically limited to small-scale applications, ongoing research explores SLA’s potential for producing modular building components, such as connectors and molds, to complement large-scale 3D concrete printing methods (Jipa, 2021).
Thesis
SLA 3D printing presents significant advantages for civil engineering applications, particularly in prototyping and specialized component fabrication. However, limitations in scalability, material durability, and cost present challenges for widespread adoption in large-scale construction.
