A 3D printer is protected from the elements in Flashforge Adventurer 4

It's a good printer and you'll need a lot of space.

The Flashforge Adventurer 3 has long been one of CNET's favorite midprice 3D printers. This feature has a few iterative improvements that make for a successful evolution.

The Flashforge is a granular self-contained system that gives you everything you need to start printing, including Prusa Slicer. While it's not as popular or full-featured as other 3D printing apps like Prusa Slicer, it's empowering to modify and slice your model, send it to your printer, and watch it through a dodgy camera.

Adventurer 4 for Flashforge is the first game of the game.

  • Fully enclosed,including the filament
  • Multiple build plates for faster setups
  • Usable Wi-Fi connection
  • Nozzles are easy to swap out
  • Small print size for such a large machine
  • Flashprint 5 software is limited
  • No true automated bed leveling

Basic printers like the Ender 3 from Creality or the Elegoo Neptune 2 can be purchased for as little as $180. The price here is especially high when it comes to the bed's dimensions, but the outside area is 220 by 200 by 250mm.

You will find a regular pack of spares, hex wrenches, and scrapers that you get in a 3D printer box. The box has also included all of the different nozzles currently available, from the standard 0.4mm to the giant 0.6mm. More on those later

The LCD is light and easily accessible.

Because the Adventurer 4 is a fully enclosed unit -- even the big spool of filament is locked inside it's far larger than the comparable, although the bed itself is smaller by 10mm on one side. The advantage of the enclosure is both security and control. If you're a teacher or a young family, you want to keep little fingers away from the hot end, which can easily reach temperatures of 265 degrees Celsius (509 degrees Fahrenheit).

The Adventurer 4 comes equipped with HEPA filters to reduce harmful chemicals that some plastics produce. This is particularly useful when a home or school is being used instead of a large workshop with good ventilation.

Plastic, a marble effect, looks great.

Great hardware, and good software

The Adventurer 4 build quality is excellent. Almost all of the problems I've encountered can be resolved by tweaking the software and adding extra cooling.

Print quality was excellent even at higher layer heights, and small details such as skin texture and dimples benefited from the standard 0.2mm layer height.

Some overhangs have been reported, but it is still a good sign.

Many of the toys I donated on the Adventurer 4 were excellent for extended usage.

It's included an extra build plate, which allows you to grab a finished build plate, swap it in a clean one, and press print again. I used the machine for nearly 15 hours straight, but it performed like a champ.

A lot of these toys have been printed for a holiday toy drive.

The Adventurer 4 was sometimes challenging to print more complex projects. I tried a large articulated dragon (which I found on TikTok by ), but although it worked well with the brand new roll of filament supplied in the box, the print quality was lacking on older filaments. I expect an $800 model to take just about anything I can throw at it.

If it's over your head, it's important that you manually set the level, and it has no mesh system to keep the Z-height constant, so there are always high and low areas.

These nozzles have different sizes and temperature ranges.


The Adventurer 4's last trick is the swappable nozzle system. Each nozzle is a stand-alone unit that you can easily pull and replace. This can give you a chance to try out different nozzle sizes to see how thicker layers can add strength while thinner layers provide attention.

Flashforge has a nozzle that can handle much higher temperatures, so you can print with ABS, PETG, or even carbon fiber for stronger printings. It also makes replacing the nozzles and clearing nozzle jams much easier, although replacements from Flashforge are cheaper than standard nozzles.

The video quality isn't particularly good, but the Wi-Fi connection is strong.

The Wi-Fi connection through Flashprint is good too. 3D printers often have poor Wi-Fi systems, but the Adventurer 4 stayed connected and the camera showed the print on everything I made. The 3D printer has onboard storage so the Wi-Fi sends the file directly there. This reduces the probability of errors caused by a bad connection.

If I were an educator, I'd prefer it as my classroom 3D printing platform. Having four of these set up in a lab would be perfect for a class of 20 or more. The bundled Flashprint software, although limited, does allow you to control multiple printers at once -- you can even see the print on a built-in camera

Despite appearing great in this picture, the print quality isn't perfect.

The Adventurer 4 is a little tricky for a hobbyist or small business, but it requires some considerations. No matter what I threw at it, from the Lincoln bust CNET to a giant dragon-horse that took up the entire build volume, the printer took it and spat out a great print.
