The Top 6 Best Open Source 3D Printers

The Top 6 Best Open Source 3D Printers
Latest posts by Total 3D Printing Team (see all)

In such a relatively short time, 3D printing has been around, few things have largely contributed to the industry’s growth. One of the biggest factors is open source printers. Open source printers allow the industry to evolve and grow to fit consumer needs as users find ways to upgrade printers.

Many big names in the industry are known for creating awesome printers with open source technology. However, over time, some of these companies have run into problems

For example, Printrbot shut its doors in 2018 because of lackluster sales. Lulzbot was on the verge of closing down, even firing a significant portion of their staff in 2019 before they were bought out.

Makerbot, which was the biggest company that had do-it-yourself printers, stopped offering open source printers. They now sell proprietary 3D printers and patented their technologies.

So a lot has changed since we came out with this list in 2017. Here are the best open-source 3D printers you can buy today.

Creality CR10

The Creality CR-10 was developed in 2016 after the success of the CR-7 and the CR-8.

The primary selling point of the CR-10 is the huge print area and three size variants. The only difference in the three variants is size, so the features and capabilities of the different options are consistent across the board.

While the CR-10 takes a while to heat up to the higher end temperatures and may require an extruder cover to maintain these high temperatures, it only prints as well as your settings, so if you dial into them correctly, it can achieve excellent prints.

While the preparation process can be a bit tedious, it truly lives up to the hype when you use it consistently.


  • Easy to assemble and has a simple design
  • Easy to troubleshoot
  • Good for bigger prints with fine details
  • Removable glass bed
  • Affordable


  • The extruder’s placement can be better.
  • When printing, you often run into tangled filaments
  • Printer preparation can take effort and time


  • Dimensions: 23.6 by 19.3 by 24.2 inches (600 by 490 by 615 millimeters)
  • Weight: 22.7 pounds (10.3 kilograms)
  • Build volume: 11 by 11 by 15 inches (280 by 280 by 381 millimeters)
  • Nozzle size: 0.4 millimeters
  • Maximum printing speed: (7.9 inches per second) (200 millimeters per second)

Bottom Line

I Personally Prefer the Creality CR 10 | Creality3D

Simply put, it's one of THE most affordable 3D printers for beginners and intermediates. A fun, durable printer for experimenting and prototyping.

Frequently Asked Questions

Open-source 3D printers are huge, as they can deliver great print quality and still be very affordable. And we know you have questions. Here are some of the queries we got from our readers:

Question: Are there any open-source 2D printers?

Answer: Technically, you can create your own 2D printer at home. But it’s not very practical to do so. The components of a 2D printer should be available if you know where to find them. However, as for prepackaged open-source 2D printer comes form years and years of research and development by various companies.
And because of all that mone being poured into research and development, these companies typically patent their work. Printer manufacturers pay other companies to use the latter’s technologies and patents. With the cost of the patents and the actual components of the printer itself, it’s not going to be economical. Finding an open-source alternative can be challenging because you’d need a lot of time and knowledge in different areas to come up with a basic printer.
All that seems not worth it, considering that some of the best printers out there cost less than $150, such as the Brother MFC-J895DW or the very affordable HP DeskJet 3755, which seels for less than $100 and still gives you great prints.
On the other hand, 3D printers have roots, in the RepRap community, largely a community project. In short, there are no patents to contend with. There is no intellectual property to buy. And the community is very helpful when it comes to finding the components you need to build your printers.
In fact, in the early days of 3D printers, most of these machines were built by enthusiasts. People improved on already existing designs to put their own 3D printers for others to improve.
With 3D printers, if you already have one, you can easily create the parts you need to create a better version. Plus, because you don’t have to worry about licenses and patents, these 3D printers were mostly more affordable than what can be bought from the store.

Question: What’s the big deal with IDEX anyway?

Answer: Independent dual extruders, or IDEX, is a technology that enables to print heads to work independently. Each of the print heads has its own nozzles and will print in different directions using different materials.
IDEX print heads are not like dual extruders, which have two nozzles on one print head. With dual extruders, you can also print with two filaments having two different materials. still, because the extruders are close together, there is a very high risk of contamination as the other nozzle might ooze and drip filament unexpectedly.
With IDEX, the other nozzle will stay idle far away from the object you’re printing. IDEX also offers you two different printing modes: Sync and mirror.
This means that the printer can print a pair of identical parts, either symmetrical parts or the exact same parts. So, if you’re using your 3D printing for serial manufacturing, IDEX technology doubles your output.
IDEX also allows for multi-material printing, where you can print a model with two or more materials. Each nozzle on an IDEX print head can have its own temperature. In sum, IDEX technology allows you to do more with your 3D printer. Some of these capabilities are absent even in dual extruders.

Question: What’s the big deal with open source, anyway?

]Answer: You might have heard the term open source when it comes to software that you use for your computer. This software doesn’t require you to pay a license fee, and you can view their codes and check to see if you can introduce improvements.
Open-source 3D printers are the result of collaboration and user-initiated improvements. In theory, you can get a better 3D printer with excellent features and the latest technologies.
Open source helps encourage experimentation among users. Not only do they have access to the codes and other things that goes behind the scenes, but they also have to worry about infringing on copyrights, patets, and other intellectual properties.

Get the Perfect Open Source Printer for Your Needs

The beauty and benefit of the open-source philosophy are that you get an excellent 3D printer that’s loaded with features without paying a steep price. Whatever money that was not paid towards licenses or patents is spent on making the machine better or goes towards a more budget-friendly price tag.

An affordable open-source printer doesn’t mean that it’s got very few features, as the Flashforge Creator Pro shows. If you’d like to get the most bang out of your money, you can get the Anet A8. Or, if you’re serious about 3D printing and want to support the open-source philosophy, there’s the BCN3d Sigma D25.
