In collaboration with NIH 3D Print and the EyeWire lab at MIT, I’ve made a 3D printed neuron! This particular neuron is a ganglion cell, which brings visual information from the retina to the brain. Its shape was revealed by gamers playing EyeWire, which uses crowdsourcing to create 3D models from serial electron microscope images. If you’d like to participate, you can sign up to play EyeWire here. If you want to try printing this cell, the model is available at the NIH 3D print database.
