FDM (Fused Deposition Modeling) is one of the most popular 3D printing technologies available to all kinds of 3D printing enthusiasts regardless of their experience. It is characterized by being straightforward and relatively easy to become decent at. In essence, 3D printers powered by this particular technology extrude melting plastics onto a build plate layer by layer to shape a three-dimensional model of choice. The maximum final size of the model that can be achieved depends on the build volume of the printer. Some makers print pre-made 3D models that can be found on websites like Thingiverse, while others dive headfirst into 3D modeling and invent masterpieces by themselves. 

Today’s article will be focusing on the comparison of two affordable yet fully enclosed FDM 3D printers made by Flashforge that come from the Inventor family. Just like the series name implies, these machines are designed to provide you with a streamlined printing experience to let nothing prevent you from inventing something the world has never seen before.


About Flashforge

Flashforge is an experienced and well-known Chinese manufacturer of professional 3D printers and printable materials that entered the additive manufacturing market back in 2011. Thanks to having its own factory and an R&D department powered by a number of gifted employees that come from the world’s best universities, the company currently holds the number one position in the domestic market. And it is a huge achievement indeed, because the Chinese additive manufacturing market is considered to be one of the most competitive in the world. Besides, the company products are exported in nearly a hundred countries around the world, which once again highlights their reliability and efficiency.


Flashforge Inventor

The Flashforge Inventor is a user-friendly consumer-grade FFF/FDM desktop 3D printer that features a fully enclosed body made from high-end injection-molded parts. Coming in a fully assembled state, it has a powerful dual-extrusion system that lets you combine and print with two different materials in one go as well as benefit from multi-color printing. The machine offers a pretty decent build volume, a reliable ventilation system, and a heated bed, all of which allow for fail-safe use in both personal and professional applications. It can print at a minimum layer height of 100 microns, providing your models with a decent surface finish.

The Flashforge Inventor can be successfully used for rapid prototyping, reverse engineering, and education, let alone the creation of household items, tabletop models, artworks, accessories, souvenirs, props, cosplay accessories, and more.



As you can see, the Flashforge Inventor is a neatly-looking machine that features a refined appearance. Made of durable injection-molding parts, the middle of its body has been painted in light blue, while its top and bottom parts were painted white. By the way, its top lid can be detached if needed. Its design can even be described as minimalistic and classical. The front of the printer is equipped with a transparent see-through window that is neither large nor too small. Thanks to its dimensions of 485 x 344 x 382 mm (19 x 13.5 x 15 inches) and weight of 10.7 kg (23.6 lbs), it can be easily placed on almost any working table.

All things considered, talking design and dimensions-wise, this 3D printer can become a perfect addition for any kind of home workshop or office. 


Features Explained

Enclosure and Build Volume

Source: YouTube.com

The Flashforge Inventor offers a build volume of 230 x 150 x 160 mm, which, as we have already mentioned, is pretty decent. It is more than enough for the production of small and even medium-scale items like details prototypes, flowerpots, door hinges, tabletop miniatures, and other similar objects. However, it won’t be enough to print really large models like a full-size cosplay costume. But truth be told, not a single consumer-grade 3D printer is yet capable of printing something that big. The common solution would be to print big objects in pieces and glue them together afterward.

Full enclosure prevents unwanted temperature fluctuations and expands the range of printable materials, letting you benefit from printing with high-temperature plastics and creating durable, long-lasting, and functional parts. Besides, the enclosure makes the whole printing process much safer by keeping kids and animals at bay. It also helps to fight off the most commonly encountered printing problems such as delamination. You can learn more about the advantages brought by the full enclosure from this article.


Dual-Extrusion System

The Flashforge Inventor is equipped with two extruders each of which, in their turn, features two nozzles that can be heated up to 240℃ to provide optimal material compatibility. Not only does it let you print in different colors and materials, but it also makes the printing process a whole lot faster since there is no need to swap one filament to another throughout the printing process, which tends to be very time-consuming.

Therefore, dual-extrusion 3D printers let you create three-dimensional objects made of two different materials a whole lot faster. This is particularly useful in the case of creating models with water-soluble filaments like PVA since PVA-based supports are easy to remove. In its turn, easy support removal ensures a better surface finish of the final model because you don’t need to scrape away all the excess material manually.


Build Plate Details

Equipped with a heated build plate that can rapidly reach a temperature of 120℃, the Flashforge Inventor benefits from a vastly improved bonding strength (i.e.layer adhesion) since the plate remains in a heated state which doesn’t let the first layers be cooled and detach until the print job is complete. Besides, it helps to fight off delamination, one of the most commonly encountered FDM 3D printing problems. By the way, the heat bed of the Flashforge Inventor is a detachable and flexible one, which allows for effortless print removal.


Resume Printing Function

Continuing on the matter of essential features that every modern FDM 3D printer should have, the Flashforge Inventor features a built-in resume printing function that lets you continue making an object even after a sudden power outage has occurred. Needless to say, this feature is extremely important if you don’t intend to reprint a large model from scratch and would like to be safe from such unexpected events.


Connectivity Options

The Flashforge Inventor is an accessible 3D printer that boasts a plethora of connectivity options. It offers Wi-Fi, USB, and SD card connectivity, letting you control the device remotely as well as adjust all the necessary settings on the fly by using its touch screen.

You can also connect to a built-in HD camera located inside the print chamber to watch your models build in real time.
