Discover Your Inner Engineer: Make 3D-Printable Robotic Arms at Home

We will talk about the top robotic arms that can be made using a 3D printer. Robotic arms are machines that can pick things up and put them down, and are often used in factories for making things like cars. They can also be used for other things like engraving or 3D printing.

These robots are very good at doing the same thing over and over again with great accuracy. They work by using small motors and servos to move the different parts of the arm. The arm moves because all of the servos work together.

You can use a 3D printer to make many of the parts you need to build a robotic arm, even if you don’t have a lot of money to spend. The exact way the arm works will depend on how big it is and what it’s made of.

There are many different projects available for making a 3D printed robotic arm. Some of them are free and can be found online. To make the robot, you will need to download the files, print the parts, and assemble them with the servos.

Here are a few projects you can try, depending on how much time and money you have, and how good you are with 3D printing:

  • LittleArm V3: This is the easiest 3D-printed robotic arm to build at home. You only need four 3D-printed pieces and 21 other parts to make it. You can control it using a USB or Bluetooth. You will need an Arduino NANO, a custom PCB, a Bluetooth module (optional), four servos, a power adaptor, and the 3D printed parts to build it. You can find more detail here
  • EEZYbotARM MK3: This is a smaller robotic arm that is easier to build than the MK2 version. You can control it using a computer, or by programming it with a pushbutton. It’s available at EEZYrobots 
  • MeArm: This is a popular open-source project that can be built using Arduino UNO or Raspberry Pi. You can either laser cut or 3D print the parts. You only need four servos, a microcontroller board, and the parts to build it. You can control it via Wi-Fi. Pocket Sized Robot Arm MeArm V0.4 : 20 Steps (with Pictures) – Instructables 
  • Kauda: This is a low-cost, 3D-printable robot that is designed for educational purposes. It comes with easy-to-follow instructions and can be built using Arduino MEGA, two servo motors, and three stepper motors. You will need 41 3D-printed pieces, Nema-17 stepper motors, MG996R Servos, a 6V extended gear DC motor with a shaft, and Arduino MEGA. 010-Kauda | DIY Tech
  • OWI Edge: This is a wireless robotic arm that comes as a kit. You can buy it on Amazon or for $43.95. It comes with a controller board, 3D-printed parts, servos, and accessories. You can control it using software on your home computer. It’s a great starter project. Robotic Arm Edge – OWI Inc. dba: Robotikits™ Direct 
  • uArm: This is a highly capable and durable robotic arm that can be used for many commercial and industrial applications. It can even be used for 3D printing or laser engraving. You can control and program it without coding by using the uArm Studio software, or by using the Python SDK if you’re a programmer. The kit can be purchased for around $800. uArm Detail here 
  • PincherX 100: This is a 3D printed robotic arm that can be used for things like artificial intelligence and machine learning. It has a precision of 5mm and can carry things up to 50g. All the parts are 3D printed using ABS.  PincherX 100 Robot Arm
