DIY Arduino 3D Printers Everything You Need To Know About Arduino

The 3D printing technology has become very popular over the past couple of years, though getting into the hobby might still be too expensive for many people due to high prices. There are plenty of affordable 3D printers that you can come across for sale, but if you’re looking to take it a step further, you can even make your own.

Arduino has given aspiring programmers one of the best opportunities to create devices that can accomplish a wide range of tasks, and 3D printing is no exception.

Top 5 Best Arduino 3D Printers

Over the course of this guide, we’re going to take a look at some of the best options you have when looking for an Arduino 3D printer project. We’ll look at projects that range from simple and barebones all the way up to some of the most versatile machines that you can hope to make on your own.

Frequently Used Parts

These printer kits are slightly different in their construction and control approach. However, there are a couple parts that you will need for any type of Arduino 3D printer:

Arduino Uno R3 controller – the defining factor of any Arduino project is the Arduino controller, with the most popular being the Uno R3. This is the core of any Arduino 3D printer build as it stores the control program used to actually run the printer.

3D printing pen or hot end extruder – any 3D printer requires a way to apply the filament to your prints, which is what these parts are used for. These parts act as the core of the mechanical part of a 3D printer by turning your rolls of filament into your own projects.

Heated bed – heavily recommended for any printer that you plan to actually use. Heated beds keep your printed objects from warping by keeping them evenly heated.

Without any further delay, let’s get right into our five best DIY Arduino 3D printer projects.

What is Arduino?

Before getting to know about the 3D printers, it is important to know what exactly Arduino is. It is a hardware and software platform for many electronic devices, mainly targeted at enthusiasts who tinker with the systems and the programming to make cool projects.

Over the years Arduino has become an integral part of numerous scientific projects ranging from the simple everyday instruments to the most complex semi-industrial ones.

Learning and understanding the inner workings of this system has become very popular among engineers and tech buffs. Hence why many instructional books like the ones shown here have popped up to help both newcomers and experienced Arduino buffs alike

It is being used as an open source platform by a lot of people, ranging from the hobbyists to the programmers. The most efficient users don’t just make use of the existent Arduino but keep adding more and more to it to improve its performance, making it sort of an open-source project shared between the enthusiasts.

With the rapid growth of 3D printing technology, it was only a matter of time since the Arduino professionals figured out how to use the platform to create cheap yet functional Arduino 3D printers. The well-known platform allows potentially infinite customization for those who know how to use it.


Reasons Why You Should Build Your Own 3D Printer

Let’s go over some of the reasons why you may wish to build your own 3D printer using Arduino, as you may be wondering whether or not you’re better off buying a pre-built option.


A Learning Experience

One of the best parts of building your own 3D printer is that you’ll be able to benefit from the experience, as you’ll likely have learned a thing or two by the end of it. If you have already used Arduino or if you plan on doing so in the future, you’ll be able to take advantage of that experience.

Of course, having DIY experience does more for you than just in the domain of Arduino, as you’ll grow handier in other areas as well. Problem-solving is a universal skill that can help you out in many different situations.


More Affordable

This will depend on the project that you pick, but you’ll often find that building your own 3D printer using Arduino will be much more affordable than opting for one that’s already made. One of the main areas where you save is in the assembly of the 3D printer, as you’ll be doing that yourself. Without a manufacturer adding to the price of raw parts, you’ll also save a lot on the machine itself.

Regardless of whether you buy the parts in a kit or if you buy them separately, building your own 3D printer can often be more economical, but you also have to consider your needs. If you require high-precision printing capabilities, then you’ll want to make sure that you have a machine made of quality parts.


You May Have Materials Lying Around

Another reason you can save quite a bit of money by building your 3D printer on your own is that you may already have some of the materials that you need. You’ll find that some 3D printers can be made with parts that are as simple as a disc drive’s motor, such as the EWaste.

Of course, if you already have some Arduino projects laying around, then you’ll be able to save even more money in the making of your 3D printer. While you’ll have to cannibalize some of your Arduino devices, the best part is that you can always put them back together again once you’re done.


Things to Consider Before Building Your 3D Printer

Let’s take a look at some of the most important factors to account for before you build your own Arduino 3D printer.


Print Area Size

You’ll need to think about the size of 3D printer that you’re looking for before making your purchase, as that will determine what you’ll be able to build in the first place. While smaller printers will be easier to assemble, they won’t be able to print out anywhere near as many items.

If you’re experienced enough in the field of Arduino projects, you may figure out a way of adding a useful heated bed to an existing project. This part will ensure that your new DIY 3D printer won’t create warped objects since the heated bed prevents separate parts of the printed object to cool before the rest.

As your 3D printer gets larger, keeping it reliable will be harder work since there will be more moving parts. With any 3D printer, you’re always balancing the aspects of size and convenience, and that’s still the case with a printer that you’ve made yourself.


What You Plan to Build

Of course, if you plan on making a DIY 3D printer, then you’ll need to account for the things that you want to make with it. Having an idea of what you’re going to build using your 3D printer means that it will be much easier for you to choose a plan that will work best for your needs. Filaments available for use with the printer are important since different materials provide different properties to the printed objects.

The main underlying issue here is precision. Larger, bulkier builds won’t suffer much from less precise Arduino 3D printer builds, while delicate projects, like tabletop miniatures or complex art pieces, may be rendered impossible to print by an insufficiently precise printer. If you don’t know what you want to make with your 3D printer, choosing the right one is often like taking a shot in the dark, so put some thought into it.


The History of Arduino 3D Printers

The story behind the Arduino 3D is very interesting. The idea originated in February 2004. It was the creation of the Adrian Bowyer who designed the concept of a machine that makes it possible to self-replicate even when working online.

He got the sponsorship and ultimately the dream came true with the first print by the RepRap 0.2 prototype. The success of this venture encouraged Massimo Banzi and David Cuartielles to come up with the first ever Arduino 3D printers. It was labeled as the second generation of the RepRap’s open source 3D printers. This integration of RepRap and Arduino was a real revolution that exhibited outstanding results at a very low price.

The MakerBot first was fitted with a RepRap Motherboard v1.1 with a Sanguino. Unlike other traditional motherboards, it was added with additional pins and the RAM was two times better. The storage was also increased. All these added features made it a great addition for the Arduino.

A massive leap in the world of Arduino 3D printers came in the form of the Ultimaker. The creators were not happy with the previously existing systems. This dissatisfaction regarding the RepRap models led to the creation of Ultimaker in 2011. The basic idea was to create something that could be assembled without any problem.



We hope that this guide has helped you find the best 3D printer project so you can make your own using Arduino. As you can see, there’s a rather wide range of choices available, each of which caters to a specific budget and required level of build quality.
