FLSUN V400 Max 3D Printer

3D printing used to force an annoying choice: print big or print fast or print clean. You could usually pick two.

The FLSUN V400 Max is one of the rare machines that tries to erase that tradeoff. It’s built around a high-speed delta platform, designed to move quickly while staying stable, and it’s aimed at makers who keep running into the same problem: your ideas are bigger than your build plate.

In this Discover-style review, I’ll break down what the V400 Max does well, where it asks you to level up your workflow, and who should actually buy it (because “big and fast” isn’t automatically right for everyone).


Quick Verdict: Who the FLSUN V400 Max Is For

Buy the FLSUN V400 Max if you:

  • Print large pieces like helmets, armor parts, statues, vases, tall prototypes, jigs, or fixtures.
  • Want high speed without turning every print into a calibration marathon.
  • Prefer the “single-piece build” route instead of splitting + gluing + sanding.
  • Plan to print often enough that time saved becomes real value.

Skip it if you:

  • Mainly print small minis or tiny functional parts where build volume doesn’t matter.
  • Need a printer that lives inside an enclosure by default for high-temp materials.
  • Want the quietest, smallest “desktop appliance” experience possible.


Why the FLSUN V400 Max Stands Out

Large-format printers are everywhere right now—but most of them get large by simply scaling up a typical bed-slinger or gantry platform. The V400 Max stands out because its core design is different: it leans into delta motion, which is known for fast, smooth movement when tuned correctly.

  • Massive build volume: More one-piece prints, fewer seams to hide.
  • High-speed delta architecture: Built to move fast without feeling flimsy.
  • Precision-focused control: Speed is only useful if the layers still look clean.
  • Touchscreen workflow: A modern interface that keeps daily use simple.
  • Stability-first frame: Big printers fail when they wobble—this one is built to resist that.

If your current printer is “fine” but constantly forces you to print in pieces, the V400 Max feels like a different category of machine.


Speed Meets Precision: The Real-World Advantage

Here’s the truth about speed specs: marketing speed and usable speed are not the same thing.

Usable speed is what you can run consistently while still trusting the surface finish, the corners, and the first layer. That’s where the V400 Max earns attention. Delta systems can maintain momentum with fewer harsh direction changes than many cartesian setups, which can translate into smoother motion at higher speeds—especially on tall or sweeping geometry.

That’s why this printer naturally fits workflows like:

  • Cosplay (helmets, masks, armor panels)
  • Large prototypes (concept models, enclosures, assemblies)
  • Education (big demo models that actually get used)
  • Small business output (repeatable parts where time matters)

When you combine “big” and “fast,” you don’t just save hours—you save days on certain projects.


Designed for Big Ideas (And Fewer Assembly Headaches)

Large-format printers usually introduce new problems: bed leveling becomes more sensitive, long prints increase failure risk, and warping becomes more noticeable.

The V400 Max is aimed at reducing those “big printer taxes” by keeping the workflow approachable. The goal is simple: help you complete large prints successfully without turning every weekend into troubleshooting.

And when your print finishes in one piece, you get benefits that don’t show up on spec sheets:

  • Stronger parts (no glued seams acting like weak points)
  • Better aesthetics (no seam filling, sanding, repainting)
  • Less time lost (fewer steps between “done printing” and “usable”)

If you’ve ever spent three hours hiding a seam that shouldn’t exist, you already understand why big build volume is a superpower.


What You’ll Like Most (Pros)

  • Huge build volume that makes one-piece prints realistic.
  • Speed potential that doesn’t automatically wreck surface quality.
  • Great for tall prints where delta motion shines.
  • Creator-friendly workflow with a touchscreen interface.
  • Excellent “value per build volume” feel if you print big regularly.

What to Know Before You Buy (Cons)

  • Footprint: Big volume means big space. Measure your workspace first.
  • Long-print reality: Large prints amplify filament quality, first-layer prep, and airflow issues.
  • High-speed tuning matters: To fully benefit, you’ll want sensible slicer profiles and stable filament.

None of those are dealbreakers. They’re just the practical realities of stepping into a “big and fast” class of printer.


Who Should Buy the V400 Max?

If your print list includes any of these on a regular basis, you’re the target buyer:

  • Cosplayers who want fewer seams and faster build cycles
  • Designers and engineers prototyping large housings or assemblies
  • Makers selling prints who need throughput and repeatability
  • Educators who need big demo models that survive handling

If you mainly print small tabletop models, miniatures, or tiny functional parts, you may get more value from a smaller “precision-first” machine and spend the difference on better filament, nozzles, and upgrades.

FAQs

How fast can the FLSUN V400 Max 3D Printer print?


The V400 Max is marketed for high-speed printing (often cited up to 400mm/s with delta motion). Your best “real” speed depends on the model, filament, and tuning—but the platform is built to run faster than typical entry-level printers while still staying stable.

What is the build volume of the FLSUN V400 Max?


It’s a large-format build volume designed for big prints like cosplay helmets, tall vases, statues, and large prototypes—so you can print more projects in a single piece instead of splitting them.

Does the FLSUN V400 Max have auto-leveling?


Yes, it includes automatic leveling to help improve first-layer consistency. On large prints, that first layer is everything—auto-leveling is one of the features that helps make “big printing” less stressful.

What materials can the FLSUN V400 Max print with?


It supports common materials such as PLA, PETG, and ABS. For more demanding materials, your success will depend on your environment (drafts, temps) and setup (enclosure strategy, tuning, and filament handling).

Is the FLSUN V400 Max suitable for beginners?


It can be, especially if your goal is large-format printing and you want to grow into the machine. The touchscreen and automation help, but beginners should be ready to learn the basics of first-layer setup, filament tuning, and long-print planning.


Final Thoughts

The FLSUN V400 Max is built for makers who don’t want their printer to be the bottleneck. It’s for the moment you stop thinking, “Can I print this?” and start thinking, “How big do I want it?”

If you’re ready for larger projects, fewer seams, and faster iterations, the V400 Max is a strong move—especially if you plan to actually use that volume instead of just admiring it.
