Best Open Source 3D printers

Open source 3D printers are very attractive to those who enjoy customizing and upgrading their machine.

Working with open-source 3D printers offers you unlimited potential and limitless upgrades. So, if you are into this type of machine, here are the best 3D printing machines to get!

1. Anet 8

Anet 8 is a budget and popular cheap 3D printer based on the Prusa i3 design. It is one of the most popular DIY 3D printers in the market. It’s in the low-end of the pricing range which makes it among the top choices especially to those who want to start 3D printing but are on a tight budget.

When it comes to the design, it is not different from other Prusa i3 clones on the surface level. It has an Open-framed design that most people will instantly recognize. The 3D printing material used in the frame is housed in an acrylic frame instead of aluminum.

Since Anet 8 is cheap you can’t expect it to be perfect. Acrylic frame is a red flag to most people since plastic frames are known for being less stable and a lot more fragile than all-metal frames. Also, since it has an open design its electronics are exposed.

A8 is not loaded with a lot of features – the thing doesn’t even have an actual power switch, which means the only way to power it down is to unplug it. But it is fairly easy to assemble because it includes the necessary hardware. However, if you are a complete novice with no prior knowledge or experience, you might find the assembly complicated and challenging.

But do not worry, the assembly instructions are easy to comprehend and follow. The entire assembly process can take six hours to 12 hours. If you are busy and can’t sit down for long hours, no worries, you can stretch out the initial setup to several days or an entire week!

Anet A8 has a large build volume which means you can print more complex 3D models. It has an open filament system and offers two connectivity options — USB connection and SD card.

Overall, it’s reliable, accurate, and a cheap 3d printer. It comes with with a fairly large build volume, so it’s a good value for money, so I highly recommend it.
