Frequently Asked Product Questions

Do you use aquarium safe materials?

Our designs are 3D printed in premium PETG plastic. PETG is a safe material suitable for aquarium use, also employed in the production of beverage bottles and food containers.

We've opted for an enhanced PETG blend, certified safe for applications involving contact with food or drink. This material boasts non-absorbent properties and exceptional resistance to salts, acids, alkalis, and solvents. It is entirely safe for freshwater and saltwater aquariums, and crafted to outlast the lifespan of your tank. Learn more »

Why PETG over PLA?

Both PETG and PLA are considered safe for aquarium use. However, PETG stands out due to its superior chemical resistance and stability. This makes it a reliable choice for ensuring the long-term maintenance of a healthy and non-toxic aquatic environment.
