This is a big printer and you will need a lot of space

The Flashforge Adventurer 3 has long been one of Nerdshala’s favorite midprice 3D printers. The updated Adventurer 4 brings a handful of iterative improvements that make for a winning development.


FlashForge is a granular, self-contained system that gives you everything you need to start printing, including the company’s proprietary software. While it’s not as popular or full-featured as other 3D printing apps like Prusa Slicer, it’s gratifying to edit and slice your model, send it to your printer and send it through a dodgy camera on a single platform. view from. I can see this system working well for teachers and hobbyists.

  • Small print size for such a large machine

  • no real automatic bed leveler

At $799 (£699, AU$1,088) it’s not the cheapest printer you can start with. Basic models like the Ender 3 from Creality or the Elegoo Neptune 2 can be bought for as little as $180. The price here feels particularly high when you look at the size of the bed compared to the overall size of the machine. The exterior dimensions are 500 by 470 by 540 mm, and the construction area is 220 by 200 by 250 mm.

Inside the box, you’ll find the usual bundle of parts, hex wrenches and scrapers found in a 3D printer box, along with the pleasant addition of 1kg of PLA filament to get you started. Mine also came with all the different nozzles currently available, from the standard 0.4mm to the huge 0.6mm. More on them later.

The LCD is bright and easy to use.

Because the Adventurer 4 is a completely enclosed unit – with even the large spool of filament locked inside it, it is much larger than the comparable Anicubic Viper, although the Adventurer 4’s bed is 10mm smaller on one side. The advantage of the enclosure is both protection and control. If you are a teacher or a young family, you may want to keep little fingers away from the hot end, which can easily reach temperatures of 265 °C (509 °F). The enclosure also helps to control temperature and block drafts to allow for more sensitive filaments such as ABS, which require more careful handling.

The Adventurer 4 also comes with a HEPA filter inside the unit that removes the toxic fumes some plastics produce. This is especially helpful when your 3D printer is in a home or school rather than in a large workshop with good ventilation. It took almost no effort to install Adventurer 4. If you’re new to 3D printing, you’ll be pleased to know how easy it was to set up and how clear the instructions displayed on the LCD are. I took it out of the box and printed a test piece in less than 10 minutes.

The Adventurer 4’s build quality is excellent. Almost all the problems I’ve encountered can be solved by making software changes and adding a little extra cooling. I made this beautiful dragon horse Luby3D, and you can see that some overhangs are not bridged correctly. I decided to leave the front door open on subsequent PLA prints, allowing the material to cool more as it came out of the nozzle.

Even at high altitudes, print quality was excellent. Layers were consistent and even in each layer, and small details such as skin texture and dimples came out well when using the standard 0.2 mm layer height.

Some overhangs were encountered, but it’s still a fine print.

I was recently part of a holiday toy drive, and many of the models I donated were featured on the Adventurer 4. This allowed me to test how well the printer holds up for extended use. It also performed well when printing 180 different models for Santa.

An additional build plate is included, which allows you to grab a finished build plate, swap in a clean one, and press print again. I used the machine for about 15 hours straight with minimal downtime, and it performed like a champ.

But it wasn’t all right. Adventurer 4 sometimes struggled to print more complex projects. I Tried A Large Articulated Dragon (The One I Found On Tiktok McGuibeer), but while it worked well with the brand new roll of filament supplied in the box, the print quality deteriorated on the old filaments. On the older stuff, I needed to increase the flow rate to get consistent layers. Jumping between new and old filaments can be challenging, but I expect the $800 model to take almost anything I can throw at it.

It is also difficult to maintain the bed level. You have to set the level manually, and there’s no mesh system to keep the Z-height constant, so there’s always a high and a low zone. If it’s in over your head, it means that setup and maintenance are more manual and less automated than on many other comparable printers. While Flashforge says the Adventurer has “auto-leveling,” what it really does is take you through a manual leveling process but automatically level the bed for you.

Extra Nozzle 4 for the Adventurer

These nozzles have different sizes and temperature ranges.

hot swappable

The last trick in the Adventurer 4 is the swappable nozzle system. Each nozzle is a stand-alone unit that you can easily pull out and replace. This may give you the opportunity to try out different nozzle sizes to see how thick layers can add strength while thin layers help with detail.

The Flashforge also has a nozzle designed to handle very high temperatures so you can print with ABS, PETG or carbon fiber for a sturdier print. This makes it more simple to replace the nozzle and clean the nozzle jam, although replacement from a flashforge costs more than a standard nozzle.


Video quality isn’t great, but the Wi-Fi connection is strong.

Wi-Fi connection via FlashPrint is also good. 3D printers can often have poor Wi-Fi systems, but the Adventurer 4 stays connected and the camera shows prints on everything I make. 3D printers have onboard storage so Wi-Fi sends files directly there. This minimizes the chances of errors caused by a bad connection.

If I were a teacher, I would want this as my classroom 3D printing platform. Setting up four of these in a lab would be perfect for a class of 20 or more. The bundled FlashPrint software, though limited, allows you to control multiple printers at once – you can even view prints on a built-in camera.

Despite looking great in this photo, the print quality isn’t perfect.

But for a hobbyist or small business, the Adventurer 4 requires a few tradeoffs. Yes, there are better printers out there for $800, but they require more work to set up and likely won’t offer the Adventurer 4K full enclosure. Bottom-line? No matter what I threw at it, as Nerdshala benchmarks from Lincoln Bust uses for a giant dragon-horse that took up the entire build volume, the printer took it and put out a great print.
