When Massimo Moretti and his team at the WASP project built their BigDelta clay printer to take on the task of printing homes from clay for third-world countries, little did they know that the technical challenges they faced would lead them to building a delta-based printer capable of astonishing speed. Moretti and collaborators like Dennis Patella took on a project to upgrade the PCB boards and firmware necessary to create the Delta WASP 20 40 Turbo, and they say it's capable of print speeds exceeding 1000 millimeters per second.

Below is a picture of the new machine. Let us know if you have tried it out. Watching the video it seems pretty legit.
