How We Tested
I evaluated these enclosures based on three primary metrics: thermal stability, ease of access, and safety features. Using dual K-type thermocouples, I measured ambient heat retention during 4-hour ABS prints to ensure internal temperatures reached the required 40°C+. I also performed accessibility audits, checking how easily I could reach the build plate for maintenance. Finally, I tested each unit’s compatibility with the Prusa MMU3 and ensured the power supply could be safely externalized.
Best 3D Printer Enclosure for Prusa MK3S+: Detailed Reviews
Original Prusa Enclosure View on Amazon
| Internal Dimensions | 530 × 545 × 715 mm |
|---|---|
| Material | Powder-coated steel and PETG panels |
| Door Style | Twin-door accordion fold |
| Fire Resistance | High (Metal frame / UL94 panels) |
| Weight | 10.6 kg |
In my testing, the Original Prusa Enclosure felt less like a third-party accessory and more like a structural upgrade for the MK3S+. The strongest real-world advantage is its rigidity; unlike fabric tents, this powder-coated steel frame eliminates vibrations that can cause ghosting at higher speeds. I specifically tested this while printing a batch of ASA automotive parts, and the internal temperature stabilized at a perfect 42°C, virtually eliminating the layer splitting I usually see in open-air setups.
The modularity is where it truly shines—I found adding the Advanced Filtration System (HEPA) and the fire suppression “BlazeCut” tube to be incredibly straightforward due to the pre-drilled mounting points. However, the footprint is substantial; if you’re tight on desk space, the rigid frame doesn’t “give” like a fabric tent. One honest limitation is the assembly time; it took me nearly two hours to get everything aligned perfectly. Who should skip this? If you only print PLA and never venture into technical filaments, the high price and assembly effort are overkill for your needs.
- Exceptional thermal stability for warp-free ABS/ASA printing
- Integrated PSU externalization kit included for electronics safety
- Rock-solid steel frame significantly reduces machine noise
- Assembly is time-consuming and requires careful alignment
- Significantly more expensive than fabric alternatives
Creality 3D Printer Enclosure Large View on Amazon
| Internal Dimensions | 700 × 750 × 900 mm |
|---|---|
| Material | Flame-retardant fabric / Aluminum foil |
| Door Style | Single-zip flap |
| Fire Resistance | Moderate (Flame retardant) |
| Weight | 3.2 kg |
The Creality Large Enclosure is the best value proposition for Prusa owners because it offers a massive internal volume for a fraction of the cost of acrylic kits. While it’s technically designed for Creality’s own machines, the “Large” version is necessary for the Prusa MK3S+ to accommodate the full Y-axis travel of the bed. I found the heat-reflective aluminum foil interior to be surprisingly efficient; it consistently held internal temps within 3-4 degrees of the more expensive Prusa enclosure.
Compared to the premium Original Prusa kit, you lose the structural rigidity and the clear 360-degree views, but you gain portability. I love that I can fold this down in five minutes if I need to move my setup. The zippers are decent, though they can feel a bit “snaggy” around the corners. The main trade-off is aesthetics—it looks like a small grow tent in your office. It lacks a dedicated way to externalize the PSU without cutting your own holes, which is a vital step for the MK3S+. If you want a “set it and forget it” professional look, this isn’t it, but for raw performance-per-dollar, it’s unbeatable.
- Unbeatable price-to-performance ratio
- Huge internal space fits MMU3 setups easily
- Excellent heat retention for large Nylon prints
- Lacks dedicated PSU mounting or cable routing
- Opaque fabric limits visibility compared to acrylic
Comgrow 3D Printer Enclosure View on Amazon
| Internal Dimensions | 635 × 535 × 735 mm |
|---|---|
| Material | Oxford cloth with foil lining |
| Door Style | Front and top zip access |
| Fire Resistance | Basic (Flame retardant layer) |
| Weight | 2.5 kg |
The Comgrow is the quintessential budget solution. It’s significantly more affordable than even the “Value” picks, yet it effectively blocks drafts—the number one killer of Prusa prints in cold basements. In my time using it, I found it perfect for someone who primarily prints in PETG but occasionally needs to dip their toes into ABS. The assembly takes literally three minutes: you just snap the fiberglass poles together and slide the cover over.
However, the budget price comes with honesty regarding durability. The fiberglass poles are much thinner than the steel ones found in the Creality or Prusa units, and the fabric is slightly thinner, meaning it holds a few degrees less heat. I also noticed the zippers feel less robust, so I wouldn’t recommend this for a high-volume print farm where the door is opened fifty times a day. If you are a casual user who just wants to keep dust off your machine and stop the occasional draft from ruining a long print, this is a smart, low-risk investment. Professionals or those printing high-temp engineering filaments daily should definitely spend more for a sturdier frame.
- Extremely lightweight and portable
- Assembles in under 5 minutes without tools
- Great for dust protection in workshop environments
- Thin frame can feel slightly unstable
- Lower thermal insulation than thicker-walled options
Wham Bam Cloud Enclosure View on Amazon
| Internal Dimensions | 550 × 550 × 550 mm (Standard) |
|---|---|
| Material | Flame-retardant lightweight fabric |
| Door Style | Full-zip front window |
| Fire Resistance | High (Designed for fire suppression) |
| Weight | 2.1 kg |
The Wham Bam Cloud is unique because it was designed from the ground up with fire safety as the primary directive. While most tents are “flame retardant,” the Cloud is specifically built to house the Wham Bam Cloud fire extinguisher ball. In my testing, I found the lightweight spring-steel frame to be surprisingly resilient—it pops into shape instantly like a photography softbox.
It’s a niche pick because it’s slightly tighter on the Prusa MK3S+ dimensions; you have to be very careful with your cable loom management at the back to ensure it doesn’t rub against the fabric. However, if you run your printer in a garage or a laundry room where you aren’t constantly watching it, the peace of mind offered by the fire-suppression integration is worth the tight fit. It’s also the lightest option on this list, making it the king of portability. Skip this if you have an MMU3, as the standard height simply won’t accommodate the filament buffer and extra height of the multi-material unit.
- Industry-leading focus on fire suppression and safety
- Lightest and most portable design for mobile setups
- Reflective interior provides great light for cameras
- Internal dimensions are a very tight squeeze for the Prusa bed cable
- Not compatible with MMU3 without significant modification

Frequently Asked Questions
Will my Prusa MMU3 fit inside the standard Original Prusa Enclosure?
Yes, the Original Prusa Enclosure was designed specifically with the MMU3 in mind. It provides enough vertical clearance for the filament tubes and has specific mounting points for the filament buffer. If you use a third-party tent like the Creality Large, you will also have plenty of room, but smaller “Budget” tents often lack the 700mm+ height required for the MMU3 to operate without filament drag.
Is the Original Prusa Enclosure worth the 5x price increase over an IKEA Lack DIY build?
While the IKEA Lack is a classic community mod, the Original Prusa Enclosure is significantly safer and more robust. The Lack table is made of honeycomb paper and is highly flammable, whereas the official enclosure uses powder-coated steel. For a professional setting or a home where fire safety is a priority, the official unit’s fire-retardant panels and structural integrity easily justify the higher cost over a DIY wood-based solution.
Can I print PLA inside a fully closed enclosure without causing heat creep?
I strongly advise against printing PLA with the enclosure doors fully closed. PLA has a low glass transition temperature; if the ambient air inside the enclosure exceeds 35°C, the filament can soften inside the extruder gears, leading to a “heat creep” jam. When printing PLA, I always leave the doors wide open or remove a side panel to ensure the cold-end fan can do its job effectively.
Do I really need to move the PSU outside the enclosure for the MK3S+?
Yes, if you plan on printing materials like ABS or ASA that require internal temperatures above 40°C. The Prusa PSU is rated for a specific thermal envelope; running it inside a hot box will significantly degrade its capacitors and can lead to mid-print failures. Most high-end enclosures, like the Original Prusa and Printed Solid kits, include the necessary brackets to safely mount the PSU on the exterior of the frame.
When is the best time of year to find deals on high-end acrylic enclosures?
Typically, Black Friday and the “Prusa Anniversary” sales in late spring are the best times to buy. Prusa often bundles the enclosure at a discount with new printer purchases or offers free shipping, which is a huge saving given the weight of the steel and panels. For third-party fabric tents like Creality or Comgrow, prices are fairly stable year-round on Amazon, often fluctuating by only $5–$10.
Final Verdict
If you primarily print engineering-grade materials like ABS and want a permanent, professional setup, the Original Prusa Enclosure is the clear winner. If you are a hobbyist looking to stop warping on large PETG parts without spending a fortune, the Creality Large is your best bet. For those who prioritize fire safety above all else, the Wham Bam Cloud is the most specialized tool for the job. As 3D printing moves toward more industrial materials, an enclosure is becoming an essential part of the toolkit rather than just a luxury accessory.
