The ELEGOO Neptune 4 Max 3D Printer is a game-changer for large-scale 3D printing, boasting a massive 420x420x480mm build volume, lightning-fast 500mm/s print speeds, and an affordable $499.99 price tag. It’s the go-to choice for enthusiasts tackling ambitious projects like oversized decor or intricate prototypes.
A few months ago, I decided to take on a massive 3D printing project—a life-sized dragon head for my living room. My old printer? It choked halfway through. Frustrated, I started hunting for something bigger, faster, and tougher. That’s when I stumbled across the ELEGOO Neptune 4 Max 3D Printer. With its insane 420x420x480mm build volume and 500mm/s speed, I thought, “This could be it.” Spoiler: It didn’t just finish the dragon—it blew my expectations out of the water. Ready to see if this beast is right for you? Let’s dive into my full ELEGOO Neptune 4 Max 3D Printer review!

I’ve been 3D printing decor for years—check out my 3D printed vases guide for proof. But small build plates and slow speeds were holding me back. The ELEGOO Neptune 4 Max 3D Printer promised to fix that with a massive build area and Klipper-powered speed. At $499.99 (with an 11% discount on Amazon), it’s a steal for what it offers. But does it deliver? Let’s break it down.
Detailed Specs of the ELEGOO Neptune 4 Max 3D Printer
The ELEGOO Neptune 4 Max 3D Printer is a beast in every sense. Here’s what you’re working with:
- Build Volume: 420 x 420 x 480 mm³—huge enough for big decor like planters or statues.
- Max Printing Speed: 500 mm/s (default 250 mm/s)—cuts print times in half compared to older models.
- Max Acceleration: 8000 mm/s²—smooth, fast moves without sacrificing quality.
- Nozzle Temperature: Up to 300°C—handles PLA, TPU, PETG, ABS, ASA, and even nylon.
- Hot Bed Temperature: Up to 85°C—great for most filaments.
- Auto Bed Leveling: 121-point (11×11) system—set it and forget it.
- Extruder: Dual-gear direct drive—smooth filament flow, less clogging.
- Connectivity: WiFi, USB, LAN—print from anywhere.
- Motherboard: Klipper high-speed with ARM 64-bit 1.5G processor—fast and smart.
- Weight: 18.1 kg (net), 26.35 kg (gross)—sturdy but not a lightweight.
- Machine Size: 658 x 632 x 740 mm³—make room for this giant!
This thing’s loaded with features like pre-installed Klipper firmware, a PEI magnetic platform, and a 60W high-temp nozzle. It’s built for big ideas and tough materials.

My Experience with the ELEGOO Neptune 4 Max 3D Printer
Assembling the ELEGOO Neptune 4 Max 3D Printer took me about an hour. The instructions were decent, but I leaned on a YouTube video for clarity—pro tip: search “Neptune 4 Max setup.” Once it was running, I printed a Benchy (that classic 3D boat test). Perfect layers, no stringing, done in under an hour. Then I went big—a 400mm-tall vase from my plant pots guide. It finished in 14 hours with zero issues.
The Klipper firmware is a game-changer. With 500mm/s speeds and input shaping, I saw no ghosting or vibrations. The PEI bed gripped filament like a champ—though I did tweak bed adhesion for ABS (check my adhesion tips). WiFi printing worked flawlessly after a quick setup, letting me send files from my phone.
But it’s not perfect. The included USB drive disconnected twice, corrupting a file. Swapped it for my own, problem solved. And yeah, it’s huge—my desk groaned under the weight. Still, for large-scale decor, the ELEGOO Neptune 4 Max 3D Printer is a dream.

ELEGOO Neptune 4 Max vs. Creality Ender 5 Max
The Creality Ender 5 Max is solid for big prints, but its 120mm/s speed feels sluggish next to the ELEGOO Neptune 4 Max 3D Printer. Plus, no auto bed leveling? Pass. The Neptune 4 Max wins for speed and ease.
ELEGOO Neptune 4 Max vs. Anycubic Kobra 3 Combo
The Anycubic Kobra 3 Combo hits 600mm/s and adds multi-color printing. But its tiny 250mm build volume can’t touch the ELEGOO Neptune 4 Max 3D Printer for large decor. Pick this if size beats color for you.
ELEGOO Neptune 4 Max vs. Original Prusa MK4
The Original Prusa MK4 is a precision king, but at $1,099 and a small 250mm build area, it’s overkill for big decor. The ELEGOO Neptune 4 Max 3D Printer offers more bang for half the buck.
Which One Should You Pick?
- ELEGOO Neptune 4 Max 3D Printer: Go for this if you want massive prints, fast speeds, and a budget-friendly price. Perfect for oversized decor like statues or furniture parts.
- Creality Ender 5 Max: Good for big prints on a budget, but slower and less user-friendly.
- Anycubic Kobra 3 Combo: Ideal for colorful, smaller decor projects—think multi-color planters.
- Original Prusa MK4: Best for pros who need top-tier precision over size.
For my dragon head and huge vases, the ELEGOO Neptune 4 Max 3D Printer was the clear winner. Your call depends on your projects!
