An enthusiast has created a 3D printer out of Lego bricks that actually works and even printed a Benchy when testing.

Alternatively, we can split the 3D array into three 2D arrays, one for each colour channel. Note, this is different from above where we kept the entries as RGB vectors, where just two entries were 0.

Learn how this popular Python library accelerates math at scale, especially when paired with tools like Cython and Numba.

Here’s how to use Cython to accelerate array iterations in NumPy. NumPy gives Python users a wickedly fast library for working with data in matrixes.
