she received training to operate the robotic 3D printer from AI spacefactory, which provided supervision during printing. Malott used a commercial beta version of the robotic 3D print system developed and manufactured by AI spacefactory, winners of the 2019 NASA centennial challenge / 3D printed mars habitat challenge. The 3D printed brain is four times the size of the subject’s brain, the scaling highlights the layer resolution of an average MRI scan the brain, weighing 75kg, was printed with recycled plastic pellets and took approximately 8 hours to print. Malott used open-source software to convert the MRI scans to a 3D surface model, which she then sliced and converted to robotic tool paths. modeled from real-world MRI data, the 3D printed brain is four times the size of the subject’s own brain, measuring 560mm x 670mm x 370mm tall. Following a few passes by various automated systems, human eyes provided a visual edit pass for some cells to determine whether or not the algorithms were identifying them correctly.Elena malott, a student from mcnair academic high school in new jersey, has 3D printed a larger-than-life brain using an experimental robotic printer developed for space applications. Machine learning algorithms carefully scanned the slice to identify the different cells and their underlying structures. This all resulted in the creation of 225 million two-dimensional images that could be stitched together to manifest a single 3D volume. A scanning electron microscope was employed next to image the sample, with a maximum resolution registering down to 4 nm.

The surgical sample was then diced into roughly 5,300 slices each around 30 nanometers (nm) thick. This slice was stained for added visual clarity, then coated in resin to protect and preserve it. Now in a huge advancement, Google and the Lichtman Lab at Harvard University has presented a mind-boggling model of a micro section of the human brain, which began with a microscopic sample obtained from the temporal lobe of a human cerebral cortex. This detailed database and its visualization tools has totally altered the way that neural circuits and pathways are understood in the fly brain. Back in January 2020, Google released the fly “hemibrain” connectome, an online database delivering the morphological structure and synaptic connectivity of approximately half of a fruit fly brain.
