Description

Bio-Media Floating and Mobile - Advanced Biological Filtration

Download and make your own FIL17-3D Apiobi bio-media with your 3D printer: floating, mobile and high-performance, perfectly printable in PETG or HDPE, for professional-level biological filtration.

This innovative 3D bio-media has been specially designed to provide optimal biological filtration, comparable to the top-of-the-line models on the market.
Its large surface area and optimized internal geometry promote the growth of large populations of beneficial bacteria, ensuring clear, stable, and healthy water.


Key features

Versatile and adaptable

  • Operates using floating filtration, moving bed filtration, fluidized bed filtration, or trickle filtration.

Ideal dimensions

  • Ø 17 mm × height 17 mm, designed for fluid water flow and maximum oxygenation.

Easy to print and produce

  • Weight per piece : 1 g → With 1 kg of filament, you can produce between 970 and 1,000 units.
  • Simple, fast and repeatable printing.

HDPE recommended (For more details and solutions, see the 3D printing tips)

  • Ultra-light, highly durable, chemical-resistant.
  • Offers a natural buoyancy perfect for moving systems.
  • Ideal for continuous use in freshwater or marine environments.

Durable and reliable

  • Lightweight yet robust, designed not to clog pumps and filters.
  • Resistant to abrasion and prolonged aeration cycles.

Filtration performance

  • Exceptional surface-to-volume ratio guarantees powerful biological filtration without overloading the system.

Total control

  • Print exactly the quantity you need → no surplus, no unnecessary expenses.

For whom?

Ideal for discerning aquarists, aquaculture professionals, filtration specialists, and anyone looking for a bio-media solution that is more effective, more economical, and fully customizable.

 

Technical Tips for 3D Printing

Printing recommendations

This bio-media was designed to be quick and easy to print, The right settings and materials are needed for prolonged immersion.


Recommended materials

  • PETG (recommended)
    This is the material I use for my own bio-medias (in white, as in the photos).
    Durable, stable, non-breakable and very easy to print.
  • HDPE
    The best choice if your printer can handle it.
    More expensive and more technical to print (shrinkage, warping), but extremely resistant, flexible and chemically inert - ideal for long-term use in aquariums and ponds.HDPE characteristics
    • Temperature resistance over 110°C
    • Excellent chemical resistance
    • Excellent resistance to abrasion and cracking
    • Very low moisture absorption
    • UV-stable and weather-resistant
  • And why not a technical filament certified for food contact? Unless I'm mistaken, no commercially available media offer this option, which is only available in 3D printing!
  • Absolutely avoid PLA
    PLA becomes brittle, swells and disintegrates on prolonged contact with water: totally inadequate media subject to numerous constraints, including constant friction 24/24 .

Recommended print settings

  • Nozzle : 0.4 mm maximum
  • Layer height : 0.2 mm
  • Walls : 0
  • High/low layers : 0
  • Infill : Gyroid 20 % (provides an excellent internal surface, perfect for bacterial colonization)

These settings produce bio-media lightweight, functional and high-performance, The internal geometry is ideal for biological filtration systems (moving bed, trickling, etc.).
