Tough to learn but pretty cool

Had some trouble setting it up but the customer service dept has been pretty helpful



Great product !

We only tried a tiny portion of what this arm seems capable of, and it has been great. We tried some drawings and some pneumatic pick and place stuffs with the kids (8 and 9) and we know we’ve got thousands of hours of fun and tinkering to come… Quality of the hardware is awesome (to be honest, I didn’t thought it would be so clean and well finished). The box/case holding all accessories is very handy. Wonderful product, worth every penny ! Thanks from France

Rotrics DexArm

I wanted a 3D-printer for a long time, with the announcement of the Rotrics DexArm i found a affordable and multifunctional device. Not only it can 3D-print, it also can do laser-engraving and cutting, it also draws and can be a toy to pick up and sort things with the pneumatic-set.

Software is not fully complete or working 100% but Rotrics is still improving that and with every update it gets better.

When comparing the features with others

I was trying to purchase a robot for educational purposes, I was surprised by the capabilities in comparison to the others in the market, Price, Precision, and Parts that come as accessories,
