Best FDM 3D Printer in 2021

Editor's Choice
PROS

Under $300

Upgradable SKR V1.4 32-bit mainboard

Impressive print quality

Dual OS

Easy assembly

CONS

Filament loading can be frustrating

Manual bed leveling

The Biqu B1 is a newcomer to the hobbyists-level 3D printer space and confidently rubs shoulders with mainstays such as the Ender and Prusa i3. It is a relatively well-kept secret that’s slowly gaining momentum among makers for its affordable price tag, great print results, and well-chosen feature set.

While a partially assembled printer, the Biqu B1’s setup is straightforward, sufficiently so not to completely confound beginners. The instructions are particularly clear and concise, aided by labeled screws and parts.

On the specification side of things, the Biqu B1 features a 235 mm x 235 mm x 270 mm build volume, 0.4 mm nozzle, a removable heated magnetic steel print bed, microSD card reader, USB port, power failure print recovery, filament sensor, and support for popular filament like PLA, ABS, PETG, and more. Another interesting feature of the Biqu B1 is the dual operating system. You can swap easily between Biqu’s proprietary touch screen interface or Marlin. Both work well and are responsive.

The print quality is impressive at this price point, whether that’s pumping out moving parts or textured showpieces. This applies to all compatible filaments, from standard PLA and ABS prints to PETG, TPU, and even nylon. However, we’d recommend swapping out the brass nozzle for a hardened steel alternative if you plan to print with nylon regularly.

The Biqu B1 lends itself well to tinkering and customization, primarily due to the SKR V1.4 32-bit mainboard with open slots there to house any upgrades you may want to integrate, a USB Type-C connector on the print head, BL Touch stand, a double z-axis port, Wi-Fi port, and Smart filament sensor slot. As stock, the Biqu B1 works a treat, but there’s scope for some serious improvements if you are that way inclined.

Best Large Volume
PROS

Large 300 mm x 300 mm x 400 mm build volume

Quiet printing

E3D Titan Aero Volcano-style hot end and extruder

Heated bed

100 micron resolution

CONS

Spool holder more of a hindrance than a helpful feature

Ignoring the questionable name, the Artillery Sidewinder X1 V4 is a well-rounded large-format 3D printer that excels at churning out thickly layered prints at great speeds. Artillery has carefully chosen and implemented features designed to perform that core function and all at a price point that sees it compete with other top choice large build volume hobbyists 3D printers.

The Artillery Sidewinder X1 V4 features a roomy 300 mm x 300 mm x 400 mm build volume and an equally hefty footprint to match. An E3D Titan Aero Volcano-style hot end and extruder is a rare feature at this price point and allows the Artillery Sidewinder X1 V4 to work with larger nozzle sizes and consistently high flows with filaments like PLA, ABS, TPU, and flexibles. There’s quite a few connectivity options, too, with USB, TF card, and USB key.

Speeds are unsurprisingly nippy, and the printer makes easy work of large prints even when pushed to the 150 mm/s maximum. Performance with different filaments falls where you’d expect at this price point with a manageable slice of imperfections here and there. With PLA, the Artillery Sidewinder X1 V4 finds its groove and produces high-quality prints consistently.

The spool holder is one of the few negatives here, as it poses more of a hindrance than acting as a helpful feature with an endless procession of tweaks and adjustments to make it barely serviceable. An easy upgrade, so a minor flaw in our eyes.

Best Mid-Range
PROS

Excellent Ultrabase Pro print bed

Good filament support

Massive build volume

Easy setup

CONS

Automatic Leveling requires manual adjustments

Among the priciest printers in our guide, the Anycubic Chiron sits firmly in the mid-range category and has the features to match. The Anycubic Chiron has the biggest build volumes among the recommendations in our list at 400 mm x 400mm x 450 mm, which allows it to produce impressively sized prints at speed ranging from 20 mm to 100mm per second depending on adjustments.

Alongside, it has a print resolution of 50 to 300 microns, ideal for high flow rate printing, especially if you swap out the stock 0.4 mm nozzle. Material support includes your standard PLA and ABS and HIPS, Wood, TPU, and the printer fares particularly well with more pliable types. Much of this is down to the pairing of a high-quality Titan-style extruder and Ultrabase Pro print bed that features a proprietary adhesive coating to ensure models stay firmly planted in place during the printing process but are equally easy to remove once completed. The heated bed reaches desired temperatures very fast, which helps with the general feeling that the Anycubic Chiron aims to get prints going quickly.

While the Anycubic Chiron ostensibly includes automatic bed leveling through a 25 point detection system that adjusts on the fly and compensates based on nozzle height, in reality, this requires manual adjustment before it springs to life. Each of the points needs to be calibrated. While this won’t be too much of an issue for those familiar with bed leveling, the ‘automatic’ label feels a little disingenuous.

PROS

Easy to use and setup

Perfect for beginners

Fully enclosed

Strong performance for basic 3D printing

CONS

More seasoned printers may quickly outgrow the printer

Attached to 3D printing is a steep learning curve, which can often be off-putting for beginners, especially with more DIY-oriented machines that require careful assembly, bed leveling, and tinkering to get printing. The Monoprice Voxel takes a lot of the complexity out of 3D printing, all at a very reasonable price point.

The Monoprice Voxel is effortlessly easy to use right out of the box with a fully enclosed, simple design, and intuitive touch screen. Rather than spending hours combing through instructions and struggling to piece semi-assembled parts together, you’ll be diving into your first print in a matter of minutes.

Under the hood, the specifications are entry-level but entirely suitable for some impressive prints: 150 mm x 150 mm x 150 mm build volume, 50 to 400-micron resolution, 0.4 mm nozzle, USB/Wi-Fi/Ethernet connectivity, heated removable bed, assisted leveling, quick-change nozzle mechanism, 2MP HD camera for print monitoring, auto filament feeding, support for 1.54 mm filament and ABS, PLA, TPU, TPE, TPC, and PETG.

Print performance is solid, especially when making more modest prints, perfect for novices trying their hands at their first creations. The lack of tinkering may hamper more experienced builders, and there is a sense that as time passes, you may outgrow the Monoprice Voxel, but this is years down the line for those only just entering the world of 3D printing.

Things To Consider

What Is Fused Deposition Modeling?

FDM, or Fused Deposition Modeling, is by far the most common and popular 3D printing process. Without delving into the technicalities of the process too much, FDM essentially uses an extruder that feeds heated thermoplastic material, or filament, through the nozzle, which then deposits the material on a print bed layer by layer to create a print.

Compared to other 3D printing processes such as SLS, SLA, or DLP, FDM printers are relatively cheap to piece together, low maintenance, easily upgradable, and are generally compatible with a range of low-cost thermoplastic materials such as PLA and ABS.

Interestingly, the FDM term is trademarked, first coined by the company Stratasys in the late 1980s when it brought the first FDM printers to market. You may have come across the term FFF and seen it used interchangeably with FDM. The reason for this is that FFF, or Fused Filament Fabrication, is a term established by the RepRap open-source project in the 2000s as it worked to create a self-replicating rapid prototype 3D printer based on the FDM process, but cautiously wanted to avoid using the trademarked FDM name. Stratasys’ trademark on the FDM process expired in 2009, opening the door for the DIY Kickstarter 3D printer phenomenon of the early 2010s.

Types of FDM 3D Printers

There are four types of FDM printers out there, although chances are you’ll end up with a Cartesian 3D printer due to the format’s popularity amongst manufacturers and hobbyists alike. Here’s a brief breakdown of each type.

Cartesian – this type of FDM printer is based on, you guessed it, the Cartesian coordinate system established by René Descartes in the 17th century. These printers piece together a build based on numerical X, Y, and X coordinates with the printhead module moving on the X and Y axes while the print bed manages the third up/down the Z-axis.

Delta – less popular than Cartesian printers, Delta printers still technically depend on Descartes’ planes but instead employ a triangular mounting system to deposit filament onto a fixed bed. Three arms are attached to horizontal rails. The arms move independently from one another along these rails to position the attached printhead as required by the print job.

Polar – unlike Cartesian and Delta printers, polar printers leave most of the work to a circular print bed, which moves freely along all axes based on a partially fixed position print head that can only move upwards or downwards. The print head acts as a polar or central point, hence the polar name, referring to the polar coordinate system, from which all coordinates are calculated to create a print.

SCARA – the best way to think of SCARA printers (Selective Compliance Articulated Robot Arm) is to think of the large robotic arms used in the automotive manufacturing process. SCARA printers are essentially miniaturized versions of these. The high cost involved in the technology means they are rarely seen in consumer or hobbyist-level 3D printers.

Filament

To the dismay of 3D printing enthusiasts, FDM printers don’t support all material types. As such, we recommend checking beforehand if your filament of choice will pair well with a particular printer. The most popular filaments for FDM printers are PLA and ABS: cheap, easy to use, and available in a broad range of colors. Different materials are suitable for various applications, and so it’s best to have a relatively firm idea of what you hope to print before committing to this or that FDM 3D printer.

Our Verdict

Editor's Choice

For us, the somewhat undervalued Biqu B1 stands as one of the more appealing FDM printers currently out there. The competitive price point, allied to impressive print quality and a wealth of great features, should see it rise the ranks of the most popular printers in the years ahead.

Sketchy name aside, the Artillery Sidewinder X1 V4 is a superb large-format 3D printer capable of very high flow rates and large layers. It’s fast, quiet, and the E3D Titan Aero Volcano-style hot end and extruder is a welcome surprise at this price point.

Those on the lookout for a mid-range 3D printer with a massive build volume should find that the Anycubic Chiron ticks all the right boxes. The Ultrabase Pro print bed is a highlight and does wonders to keep builds in place, which generally results in fine prints. The supposedly automatic leveling may irk some, though.

3D printing, despite a steep learning curve, should be easy for newcomers, and the Monoprice Voxel goes a long way to realize that ambition. Tremendously well-designed and straightforward to use, Monoprice Voxel shines because of its user-friendly attributes and is a strong option for first-timers. Finally, the Creality Ender 3 V2 is popular for a reason and wins out as our choice for a budget, reliable FDM printer.
