A Comprehensive Geeetech A20M 3D Printer Review

Features, Specs and Model Information

The under-$500 price range for 3D printers is becoming a very crowded market niche, which is probably a good thing for consumers. For manufacturers, that means plenty of competition. Many of the high-end 3D printers call for sophisticated technical ability and a major financial hit.

This printer is priced well under $500, with a retail price of $399. Note that various sellers offer discounts up to 20 percent, so if you shop around you can snag very attractive deals.

The beauty of this Geeetech model A20M is that it’s priced right, doesn’t require you to be mechanically inclined to set it up, and includes dozens of features that would normally push the product cost up by hundreds of dollars. Most users report being able to go from unboxing to full operation in under an hour, depending how many first-time adjustments need to be made.

The printer is not fully assembles when it arrives but the enclosed brochure/pamphlet includes easy-to-understand instructions accompanied by photographs.

Pros and Cons

No product is perfect because every consumer has their own likes and dislikes. Here are the most common pros and cons found on Geeetech A20M 3D Printer Review sites


-Within its price range, the unit clearly a bargain based on the number of features, specs and overall quality

-The color photos and plain language in the instruction booklet are a nice touch and help new users get up and running quickly

-The quality of print detail is high and the build volume is large

-There is more than adequate filament support for new and experienced 3D printer users

-Bed-leveling is automatic


-Some buyers report a wobbly bed out of the box

-It takes a while to adjust the alignment of the Y-axis wheel

What Consumers Think

Based on hundreds of product reviews of this unit, the overall consensus is that the item is low-priced, offers a generous number of features, is easy to set up, has excellent customer-service support, has a vast user community with multiple forum-discussion opportunities for owners, and usually arrives with all required parts.

How it Compares to Other 3D Printers

-Layer heights:

Many of the more expensive 3D printers feature layer heights in the 50 to 100 micron range, so the A20M’s 100-400 micron range is a nice improvement for users who want better range.

-Bed leveling:

The majority of 3D printers in this price range require the user to do a bit of DIY when it comes to bed-leveling, even if that only means adjusting a few turn-screws. This unit, however, features a fully automated bed-leveling function, which means you can spend time calibrating the machine to your own preferences rather than having to use an hour of your time dealing with the bed level.

-“Print resume” feature:

The printer has “break-resuming” capability as well as a very convenient reset button, which are not common on all products in this price range. If you need to turn the printer off for any reason, you can simply stop the job, do what you need to do, and then apply break-resuming to start again, exactly where you left off.

-Setup time:

Many medium and high-end 3D printers take a long time to set up and include hard-to-understand instruction pamphlets. That is not the case for the Geeetech A20M. The included SD card and USB connectivity make setup a snap. Most users can go from box-opening to printing in under an hour.

Begin by installing the upper gantry kit and filament holders onto the building base. After that, there’s a bit of wiring work that is simple and fully delineated in the color-photograph instruction booklet. Compared to competitors in this dollar-price range, the A20M sets up in about half the time.

-Main competitors and print speed:

Competition in the same price range as the A20M, includes printers like the Monoprice Select Mini 3D, Alunar 3D Desktop, XYZprinting da Vinci Jr, Printrbot Play, Wanhao Duplicator i3 V2, FlashForge Finder, QIDI TECH I, ROBO 3D R1 Plus, FlashForge Creator Pro, and the Dremel Idea Builder. Keep in mind that the Geeetech A20M has a top build speed of 180 mm per second, while most of its direct rivals are in a speed range of approximately 40-200 mm per second.

For the price, and considering the other helpful features of this printer, a 180 mm/s print speed is considerably superior to the majority of the Geeetech’s primary competitors.


Consumers who want to work within a reasonable budget will find the Geeetech A20M a worthwhile choice. It is not as big as some of the higher-priced models but it does feature a very stable base, a single nozzle, and a dual extruder. So, for about half of what you’d pay for a nearly identical set of features, you can acquire this printer and get started without having to be a mechanical genius.

Geeetech makes other printers that straddle this one in price and capability, but the A20M is a nice choice for those new or moderately experienced with 3D printing. It also represents one of the best 3D machines you can get for the price.
