Meet LIX. It is a 3D printing pen that is deemed the smallest in the world. This handheld pen was launched on Kickstarter. According to its developers, it comes with an extremely compact design but still can be powered up with electricity via a USB port. All you need to do is turn it on for some warm up and then you are all set to create your own vertical illustrations.
Its description further discusses that it can melt and cool down colored plastic so that you can be able to come up with solid structures. Its hot end nozzle is what’s powered by the USB port. It is totally lightweight and well engineered.
It is a must check out item!
