Best Enclosure for Creality Ender 3 S1
If you’ve been pushing your Creality Ender 3 S1 to its limits, you’ve likely encountered the “ABS headache”—warping, cracking, and inconsistent bed adhesion caused by stray drafts. While the S1 is a fantastic direct-drive machine, its open-frame design struggles with high-temp filaments. I’ve tested several setups to trap that heat effectively, and for most users, the Creality Official Enclosure is the gold standard for safety and thermal stability. Let’s dive into the best options to keep your prints stuck and your workspace fume-free.

Best Enclosures for Creality Ender 3 S1: Detailed Reviews
Creality Official Enclosure (Medium) View on Amazon
I find this official “tent” style enclosure exceptional because it’s specifically engineered for the Ender series footprint. The Ender 3 S1, with its top-mounted spool and rear cable clearance, fits comfortably inside the medium version (approx. 18.9 x 23.6 x 28.3 inches). The interior is lined with a high-efficiency flame-retardant aluminum film that doesn’t just prevent fire spread—it reflects heat back toward the bed. This is a game-changer for printing PETG or ASA, as it maintains a stable ambient temperature that prevents delamination. I’ve noticed a significant reduction in noise too; the thick PVC fabric dampens that high-pitched stepper motor whine. The only minor drawback is the lack of a dedicated exhaust port, though you can easily unzip a corner. It’s a rugged, reliable choice that justifies its slightly higher price through superior build quality and peace of mind.

Comgrow 3D Printer Enclosure View on Amazon
The Comgrow Enclosure is the unsung hero for S1 owners who want professional-grade thermal management without the “brand name” markup. It’s remarkably similar to the official Creality tent, featuring a sturdy fiberglass rod frame and a heat-reflective lining. In my testing, it holds a steady 35-40°C ambient temperature during long PLA or PETG prints, which is exactly what you need to prevent warping on large-format parts. You’ll notice the fabric is slightly thinner than the premium options, but it’s still effective at blocking drafts and capturing dust. For the S1, make sure you opt for the medium size to account for the bed’s movement along the Y-axis. It’s an honest, no-frills product that does 90% of what the top-tier models do at a fraction of the cost. If you’re just starting to dabble in materials beyond PLA, this is your best entry point.

SainSmart 3D Printer Enclosure View on Amazon
If you primarily print PLA but hate how dust settles on your Ender 3 S1’s lead screws and build plate, the SainSmart Enclosure is a fantastic low-cost solution. It provides a dedicated “safe space” for your machine. While it lacks some of the heavy-duty thermal insulation found in the Creality or Comgrow models, it’s remarkably effective at blocking cold air from open windows—the primary culprit of “random” print failures. The viewing window is large and clear, allowing you to monitor your first layer without unzipping the front. It’s slightly more compact, so cable management for the S1’s side-protruding ribbon cable needs to be tidy. It won’t turn your printer into a high-temp industrial beast, but it creates a controlled environment that improves print consistency for the casual hobbyist. It’s simple, effective, and won’t break the bank.

Creality Large Fireproof Enclosure View on Amazon
For those who have upgraded their Ender 3 S1 with a top-mounted LED bar, a camera, or a secondary spool holder, the “Large” version of the Creality enclosure (approx. 27.5 x 29.5 x 35.4 inches) is the only way to go. The extra vertical clearance is a luxury you’ll appreciate during maintenance—you can actually reach inside and tweak things without pulling the whole printer out. It uses the same high-grade fireproof material as the medium version but offers better air volume, which can actually help stabilize temperatures more evenly over long, 48-hour prints. I’ve found this setup ideal for professionals who need to print ASA or Nylon, where even a slight temperature fluctuation can cause structural weaknesses. It’s bulky, yes, but the added space for tools and internal lighting makes it feel like a dedicated workstation rather than just a cover.

YOOPAI 3D Printer Enclosure with LED View on Amazon
The YOOPAI enclosure adds a layer of convenience that most others overlook: integrated lighting. If you’re like me and love watching that first layer go down via a webcam, you know how dark these “tents” can be. The included LED strip solves this instantly. Beyond the light, it features handy side pockets for your scrapers and snips, which keeps the Ender 3 S1’s workspace organized. The thermal performance is on par with the Comgrow, though the zippers feel a bit more robust. I specifically recommend this for users who have their printer in a garage or workshop where ambient light is poor. It’s a thoughtful package that combines protection with practical usability, ensuring you don’t need to hack together your own lighting solution. The fit for the S1 is perfect, with enough room for the bed to travel fully without hitting the back wall.

Frequently Asked Questions
Will an enclosure make my Ender 3 S1 quieter?
Yes, significantly. Most enclosures use thick, multi-layered fabric that acts as a sound dampener. While it won’t eliminate the sound of the fans or the stepper motors entirely, it muffles the high-frequency noises that often carry through walls. If your printer is in a living area, an enclosure can make the difference between an annoying background hum and a barely noticeable whisper.
Do I need to move the power supply outside the enclosure?
For most hobbyist prints like PLA or PETG where the internal temp stays under 40°C, the Ender 3 S1’s power supply handles the heat fine. However, if you are printing high-temp materials like ABS for 10+ hours and the chamber hits 50°C+, it’s a good practice to move the electronics outside to prevent premature component failure due to heat soak.
Can I print PLA inside a closed enclosure?
It’s actually a bit of a risk. PLA likes to be cooled quickly. If the enclosure gets too hot, you might experience “heat creep,” where the filament softens before it hits the nozzle, leading to clogs. I recommend leaving the front flap slightly unzipped when printing PLA to allow just enough airflow while still protecting the print from sharp external drafts.
How does an enclosure help with ABS and ASA?
ABS and ASA shrink as they cool. In an open-air environment, the bottom layers cool faster than the top, causing the print to pull away from the bed (warping). An enclosure traps the heat from the bed, creating a warm “micro-climate.” This allows the entire part to cool slowly and uniformly once the print is finished, resulting in much better structural integrity.
Is the “Medium” size really necessary for the S1?
Absolutely. I’ve seen people try to squeeze the S1 into “Small” enclosures, only to find that the bed hits the front or back of the tent at the extremes of the Y-axis. The S1’s cables also need room to flex. The Medium size (roughly 48x60cm base) provides the necessary clearance to ensure your motors aren’t straining against the enclosure walls.
Final Verdict
For the vast majority of Ender 3 S1 users, the Creality Official Medium Enclosure is the smartest investment for consistent print quality and safety. If you’re on a tight budget but need to stop your PETG prints from warping, the Comgrow is an excellent alternative. For those building a professional-grade station with cameras and lights, the Creality Large offers the breathing room you’ll eventually crave.
