Robo 3D R1 3D Printer Review After One Year of Use.

With the Robo 3d R1+’s simple interface and limitlessly upgradeable hardware, it is no wonder why so many beginners and advanced users flock to this printer. For the price of $499.99, you could have the printer capable of auto bed leveling, printing any material, and assembled and tested in San Diego, California.

About Robo 3D

Robo 3D started out on Kickstarter back on December 18th, 2012 lead by the businessman Braydon Moreno. They launched their first product the Robo 3D R1 3D Printer Original Version on February 1st, 2013 as they were funded $649,663 with 1,251 Backers. Later on, they would go on to become a success going onto making the New model of the Robo 3D R1+ and the Robo 3D C2 and R2.

Included items

  • Robo 3D R1 + 3D Printer
  • Power Cable
  • 500-gram spool of Robo blue PLA
  • Quick start guide
  • SD Card
  • 1-year of Fusion 360
  • Tool kit (includes lubricant, allen keys, and tweezers)
  • 3” USB cable



When you first receive the box after about 3 days of shipping (give or take a few days depending on your location) you will have a large 23lb box waiting for you. It arrives in a high-quality color printed box you can easily cut the top flaps off and slide the first piece of foam out. When you first open up the box you will realize they did not go cheap with packaging as you remove extremely high-quality protective foam. As the first piece of foam comes out you see what’s included.


Setup is quick and easy as you slide the 21lb printer onto your desk. Note you must always check your power supply on the back, 110V for US and 220V for Europe/Asia. After your power supply is configured you can plug in and turn on your Robo 3D printer. As you can hear, a slight hum will start as well as two LED lights in either corner of the printer. This LED light is a great feature adding light to illuminate the build platform as well as acknowledging to the user that the machine is on. You will next be instructed to open the SD card with video instructions and a link to the Mattercontrol Slicer. With my experience in Mattercontrol I find it a weak software slicer that doesn’t allow much tinkering with settings so I opted to use the printer with the slicer Cura. After the initial download and simple setup of Mattercontrol I then attempted to connect to the printer with the USB cable. It immediately connected and I attempted my first print. *tip (if you ever have trouble connecting to a 3D Printer, check the port for baud rate synchronization to the board or missing chipset driver in windows).

Test Print 

I watched as the Robo 3D R1+ 3D Printer did its first auto bed level since coming from the factory. It hit 9 points on a 3×3 grid pattern then got to work on a 3D Benchy test print. It started laying out with thin layers and let the printer go till finish. The print looked fine except for the thinness of layers that demonstrated under extrusion. I tried increasing flow rate but that did not solve the problem. Then looked at the included spool holder and determined that was the problem. It was causing so much resistance as it pulled over the plastic cover that it was under extruding. I immediately went on and downloaded a spool holder that would go directly above the extruder. I printed the holder with the lowest quality settings checking in every 5 minutes to make sure the filament was loose enough for the extruder. As the two-part spool holder was finished It took me about a minute to install and put the filament on. I then tried the same print and as suspected, it fixed the under extrusion. That small benchy looked great. 

On to some torture tests. First I tried a retraction test. There was no stringing whatsoever, excellent results. Next, I tried an overhang test and due to the printers high power print cooling fan, and good results except for a little drooping at 70 and 75 degrees. Next test was bed leveling. To my surprise, it had trouble with a few zones of the bed. Ran the test again to be sure and the same thing occurred. I inspected the auto bed leveling operation and discovered it didn’t use any “auto” bed leveling. What I found were two endstop sensors. I then took a close look and noticed that the sensor triggers were such a tight fit that they were getting stuck.  To combat this I used some WD-40 and fixed the problem and print test continued.

On observation, I realized it was a bit noisy. Since the Robo uses A4988 drivers it can sometimes be quite loud. You would definitely not want this printer around while watching Tv or youtube. I then tried printing ABS on it and that printed decently. There was a tiny bit of lifting, but that could be solved by using bed adhesion solution.

After that print on the ROBO 3D R1+ , I opted for something large so I printed a large Pikachu filling the whole print area and was amazed. All the overhangs were tight and had no drooping. The top layers were also filled with no gaps. All this testing was convincing me how decent this machine is.

For all of you beginners/experts in 3d printing that want something that is well assembled and high quality without burning a hole in your wallet, this may be your choice. This is also great for children, schools, makerspaces, and shops due to the plug and play functionality. Another PLUS is the Out of the Box, no assembly ease.

After a year of use, my opinion is this printer isn’t perfect but is good. Later as I got to know this machine, a little bit of spare time to make a few mods you to could appreciate this rig as much as I do now or more.

Please be sure when you buy any product like a 3D Printer that it includes a reputable warranty and service program. Unless you are an expert operator, you don’t want Alice the secretary at the Alibaba store answering your customer support questions or technical needs. That is why so many are cheaper. Many even offer they call “extra warranty”. It’s actually your option to buy a warranty plan or decline warranty support for the savings. Please be aware.
