According to the instructables,I am trying to make a robot arm like this one.Fortunately,this robot arm project is open source.I can DIY one!!
But I want to make a Acryllc robot arm ,because it is cheaper.The acryllc arm will be as high precisely as the metal one? I’m not sure.Can you give me some advice?Thanks

The accuracy of the arm depends mostly on the motors and controllers used. Changing the material to acrylic will make it more fragile, but so long as the material retains its shape and nothing breaks, it will be just as accurate as the metal one.
