![]() With circuitry that can be purchased from any good electronics store or wholesaler, the 3D printed arm is a great example of progression for hobbyists or professionals looking to hone their skills. And their 3D printed robot arm is as grand as it is cool. The Instructables Workshop has featured lots of amazing 3D printing projects over the years, with a library big enough to have something for everyone. This is where the scale and intricacy start to rise. Whatever you need, they have you covered. Do you have your own controller you prefer using? You can just get a MeArm without any add-ons. Want to pre-program the arm? There’s a BBC micro:bit kit compatible with Microsoft Make Code. Want to control the arm using joysticks? MeArm has kits for Arduino and Raspberry Pi, as well as many more. And on top of all that, it comes with a healthy choice of control options for whatever tools you have available. The parts are deliberately simple and easy to fit together. The MeArm is intended to be easy and fun, with an array of different color schemes. ![]() You can even use a laser cutter if you don’t have a 3D printer to hand. The kits are available to buy on Amazon if you didn’t feel like printing it yourself, but you can also access all the open-source files you need. Hailing from United Kingdom, MeArm is the 3D printed robotic arm project that can cater to anyone. Image credit: Eezybotarm 3. MeArm: The Everyman 3D Printed Robotic Arm But when focusing on the accessibility of 3D printable robotic arms, the EEZYbotARM MK3 is your best bet. ![]() If you are looking to try something a little more physically impressive, the MK2 is the clear choice. It was made using ABS, but PLA is also very possible. The MK2 was created to be a little larger and stronger than its predecessor, but the MK3 returns to the smaller design, with a focus on cheaper motors and construction costs. The MK3’s design is very similar to its original. While it doesn’t have the strength to handle a significant payload, it’s definitely a project worth using as an experiment. The main enhancement is its 4 directions of freedom, with a rotating base, 2-finger gripper, and a pivot in the arm that allows it to bend. Developed by Carlo Franciscone, an engineer from the Novara, Italy, the EEZYbotARM is a slight step up in complexity from LittleArm. The EEZYbotARM is an ever-evolving 3D printing project that is currently on its third form. Just like David against Goliath, don’t write off the little guy just yet. With little more than a 2C motor and a roll of PLA filament, you can construct the 31 parts needed to build this rugged and flexible arm that can be assembled in less than an hour. With only 3 degrees of freedom, meaning 3 points of movement on the arm, it is very easy to understand, both when 3D printing and programming. Crucially, it is that simplicity that makes it so useful.Įverybody has to start somewhere, especially in 3D printing, and LittleArm is the ideal entry level project to get you hooked on 3D printed robotics. But that does not make it totally useless. As the name suggests, LittleArm is the smallest, most simplistic, and easiest to print of all the robotic arms on this list.
