Designed into the model
The internal architecture is created by the geometry itself. The demonstrated print uses 0% sparse infill.
Aquatic filtration · Engineered in three dimensions
An engineered three-dimensional structure designed to bring water into contact with internal and external surfaces for microbial colonization.
Developed by Rey’s Kreations, BioCore explores how deliberately designed pathways and structural geometry can serve aquatic biological filtration.

Developer-supplied presentation. The video is illustrative; technical and performance claims have not been independently verified for this page.
Purpose-built internal architecture
An exterior structural boundary surrounds a network of openings, chambers, passages, ribs, walls, cross-members, and structural junctions.
The internal architecture is created by the geometry itself. The demonstrated print uses 0% sparse infill.
Openings and passages are intended to allow water to move through the structure and contact its surfaces.
The structure is intended to provide fluid-accessible surfaces for microbial colonization in aquatic filtration systems.
From the development workspace
These supplied slicer previews show toolpaths and model geometry. They are not photographs of finished parts or biological test results.

The demonstrated embodiment
A generally cubic example of a broader three-dimensional architecture.
The cube is the primary demonstrated form. The underlying design concept is not restricted to a cube, a single dimension, a particular material, or a manufacturing method.
The model data below were supplied by the developer for Biocube.3mf. The file has not been independently analyzed for this page. Computational mesh area is not a measurement of biologically active or water-accessible surface area.
| Bounding box | ≈ 16.128 × 16.114 × 16.128 mm |
|---|---|
| Vertices | 13,855 |
| Triangles | 26,554 |
| Computed mesh surface area | ≈ 4,081.47 mm² |
| Enclosed volume | Not established: the mesh is not a closed solid. |
Developer-reported example: FDM/FFF on a Creality K2 Plus, using a 0.4 mm nozzle, 0.28 mm layer height, 0.20 mm first layer, 3 wall loops, and 0% sparse infill.
Demonstrated materials include PLA Pro and PETG/CR-PETG. These are current examples, not limits on the architecture or future manufacturing approaches.
Proposed design directions
Alternative embodiments under consideration include rectangular, cylindrical, tubular, hollow-core, modular, stackable, interconnected, variable-porosity, flow-directed, and other three-dimensional structures.
Proposed embodiment
Specifications, pricing, and availability to be confirmed.
Proposed embodiment
Specifications, pricing, and availability to be confirmed. The name is not a measured flow-performance claim.
Proposed embodiment
Specifications, pricing, and availability to be confirmed. Reef compatibility is not established here.
Product names identify commercial concepts; they do not define the boundaries of the underlying architecture.
Intended application environments
Potential uses include multiple units in aquariums, freshwater and saltwater systems, reef systems, sumps, reactors, canister filters, ponds, and aquaculture systems.
These are intended application areas, not demonstrated compatibility or performance results. Filtration efficiency, microbial capacity, flow rate, durability, and livestock safety have not been established by the information supplied for this page.
