Frequently asked questions
What materials are used to create your 3D-printed décor, and why are they aquarium-safe?
Every item is printed in either PLA+ or PETG filament sourced from U.S. manufacturers who provide third-party safety certifications. PLA+ is a plant-based polymer that is inert once printed and fully cured, while PETG offers superior impact resistance and a slightly higher glass-transition temperature, making it ideal for warmer aquaria or terraria. Both materials are free of BPA, heavy metals, and plasticizers, and have been soak-tested in fresh and brackish water for extended periods to confirm that they do not leach harmful compounds or alter pH.
Do I need to cure or seal the décor before adding it to my tank?
No additional curing is necessary. Each piece undergoes a two-stage post-processing: first a mechanical de-burring and edge-smoothing to remove any print artifacts, then a 24-hour rinse and soak in dechlorinated water to remove micro-particulates. You may give the item a quick rinse in your own dechlorinated water for peace of mind, but it is otherwise ready for immediate use.
How long do custom orders typically require?
Lead time depends on design complexity and current print queue. Simple size adjustments ship within 5–7 business days, while fully bespoke structures that require iterative prototyping can take 10–14 business days. We provide a written timeline and progress updates—including preview photos—so you can plan your aquascape with confidence.
Are the edges safe for delicate fins, antennae, or reptile skin?
Absolutely. After printing, each item is hand-finished with progressive-grit wet sanding and inspected under magnification to ensure a sub-0.2 mm surface roughness (Ra). This eliminates sharp ridges that could snag fins, barbels, or delicate exoskeletons.
Are these products suitable for reptiles, amphibians, or isopod terrariums?
Yes. PETG’s higher temperature tolerance (softening point ~80 °C) makes it safe for habitats with moderate basking spots, while PLA+ is perfectly stable in typical terrarium humidity and ambient heat. Both materials are non-toxic to amphibians and terrestrial invertebrates. For enclosures exceeding 40 °C at the basking surface, PETG is recommended.
How durable are your pieces compared with natural stone or ceramic décor?
While lighter than ceramic or stone, our 3D-printed structures achieve a tensile strength of 50–60 MPa (PETG) and resist typical aquarium impacts. They are less likely to crack under accidental drops and exert significantly less stress on glass panels, making them ideal for nano and rimless tanks.
What is the recommended cleaning procedure over the life of the product?
Rinse with tank water during regular maintenance to remove biofilm. For stubborn algae, use a soft toothbrush or dedicated aquarium-safe sponge. Avoid bleach or harsh solvents, as these can degrade filament integrity. If deep cleaning is required, a brief soak in a dilute (3%) hydrogen peroxide solution followed by thorough rinsing is safe.
Do you offer wholesale or professional aquascaping partnerships?
Yes. We supply breeders, fish stores, and professional aquascapers with volume-priced orders and private-label options. Please contact us with projected quantities and timeline; we can provide bulk packaging and custom branding upon request.
Do you ship internationally and handle customs paperwork?
Yes. We ship worldwide from the United States with full HS codes and material declarations to streamline customs clearance. Buyers are responsible for local import duties or VAT. For EU customers, our packaging includes CE-compliant material data sheets upon request.
Can these items be painted or sealed for a different look?
If you wish to add decorative finishes, use only epoxy-based or aquarium-certified polyurethane coatings. These coatings must be fully cured for at least seven days before submersion. We also offer multi-filament prints that achieve natural gradients without the need for additional paint.
