The block-laying switch engine (or block-making switch engine) is a puffer that was found by Charles Corderman. It consists of a switch engine reacting with blocks to create an infinite number of new blocks (eight new blocks every 288 generations).

It is the most common naturally-occurring pattern that exhibits infinite growth, and is one of only two patterns that exhibits infinite growth that has been known to occur naturally (the other being the glider-producing switch engine).

Because of its easy construction (see the predecessor below), it has appeared in some superlinear growth patterns including mosquito 1 and mosquito 2.[1]
