Is high volume 3D printing for Aquarium & Terrarium projects always the best choice? Choosing the right size 3D printer for beginners with the right print volume is crucial, especially when creating durable and visually appealing aquarium and terrarium accessories. Your printer’s size directly influences the complexity, durability and efficiency of your projects. Selecting an inadequate printer size could result in excessive post-processing, weaker structures or unnecessary expenses.

Aquarium accessories like fish caves and decorative items usually require moderate print sizes, whereas terrarium animals such as reptiles and amphibians typically demand larger hiding structures. Thus, high volume 3D printing becomes essential when crafting durable hides and caves in one piece, ensuring structural integrity and visual quality.
Designing modular pieces can help overcome size limitations. However, larger prints are often superior, as they reduce the need for multiple joints, which can weaken structures.
Common projects and their typical dimensions include:

When trying to figure what is a good 3D Printer for Beginners, avoid these typical pitfalls:
CoreXY printers usually offer better stability compared to bed-slinger designs.
For beginners passionate about aquarium and terrarium projects, a 250x250x250 mm (10x10x10 inches) build volume is a balanced choice. It accommodates most caves and hides without extensive assembly. If you’re planning larger terrarium shelters or single-piece aquarium caves, opting for 300x300x300 mm (12x12x12 inches) is ideal.
Smaller printers can still handle bigger projects through slicing and assembly with high-strength glue. However, larger print volumes simplify this process, minimize weak joints and enhance the overall structure.

Print size alone doesn’t guarantee success: print quality, filament adhesion and stability are equally critical, especially for larger aquarium and terrarium designs. Poor adhesion can lead to failed prints, wasted filament and structural weaknesses.
Ensure optimal adhesion by using:
Based on my extensive experience (over 130 k hours) in 3D printing, for larger, multi-part prints, using specialized adhesives is highly recommended. Based on my five years of 3D printing experience, I strongly advise applying a high-strength glue to assembled parts to reinforce structural integrity and prevent potential breakage. This approach enhances both the durability and longevity of your creations, making them better suited for long-term use in aquariums and terrariums.
So, is high volume 3D printing always the key and the ultimate benefit? Not always — but in many aquarium and, especially, terrarium projects, it gives you a serious edge. The right print volume depends on your goals. Small builds like feeding dishes and ledges don’t need massive machines, but when you’re crafting large hides, ramps or modular scapes, high-volume printers reduce slicing, seams and weak joints — all while improving durability and visual impact.
👉 My personal observation and experience shows that for most aquarium setups, a printer with 220x220x250 mm (8.7×8.7×10 inches) volume suffices (a Sovol SV06 ACE* would be a good start for beginners considering it’s quality, print volume and price), while terrariums typically require at least 250x250x250 mm (10x10x10 inches) – a Bambu Lab A1 would be a good choice. Larger projects benefit significantly from high volume 3D printing, ideally with a 300x300x300 mm (12x12x12 inches) printer (a Creality K2 Plus* will do good here), minimizing assembly and maximizing strength.
