MARS is a ceramic 3D-printed modular system designed to construct reef habitat without the need for heavy-duty equipment. The system can be deployed from small boats and assembled by divers, making it suitable for reef restoration projects in locations where large marine construction equipment may be difficult to use [(MARS2026)]. | + | One of its well-known systems is MARS, which stands for Modular Artificial Reef Structure.

| - | A cement-based prototype is closer to the final concrete-based product because it can better represent the general appearance, surface texture, weight, and handling of the Reef Block. Concrete is widely used for artificial reef construction and can be used to create complex shapes for marine habitat structures [(ArtificialReefPreparation2026)]. In this approach, PLA filament is used to produce a 3D-printed mold, and cement is poured into the mold and left to cure. Therefore, PLA is not used as the final material of the Reef Block prototype, but as a tooling material for shaping the cement-based model. PLA is suitable for this purpose because it is commonly used for rapid prototyping and can also be used for mold inserts or casting-related applications [(PrusaPLA)][(UltiMakerPLA)]. | + | A cement-based prototype is closer to the final concrete-based product because it can better represent the general appearance, surface texture, weight, and handling of the Reef Block.

| - | This option allows the team to combine the geometric accuracy of 3D printing with the more realistic material behavior of a cement-based prototype. It is also low-cost and possible to produce locally. However, the prototype is not intended for real underwater deployment, and normal cement does not fully represent the final basalt fiber-reinforced concrete. Therefore, this option can be used to check the general shape, handling, assembly, and Smartlogger attachment, but it cannot prove long-term durability or full structural performance in marine conditions. For the final product, basalt fiber-reinforced concrete would still be required because it is more suitable for long-term marine exposure and resistance to chemical and environmental degradation [(BasaltFiberMarine2025)][(QU2021)]. | + | This option allows the team to combine the geometric accuracy of 3D printing with the more realistic material behavior of a cement-based prototype.
