While laser cutting remains the dominant force for rapid prototyping anything made of plastic, MDF or wood, the real holy grail is the ability to cut metal — something most laser cutters are just not capable of.
In the industry, this is done using extremely high-powered laser cutters, plasma cutters, or water jet cutters. All of which are very pricey equipment for a hacker. Until now anyway. Introducing the Tinijet, the missing tool for affordable water jet cutting.
We first covered this project a few years ago when it was just a university research project called Hydro — it’s since evolved immensely, and will be available for sale very soon.
While the following video is just a rendering, they demonstrated a prototype of the unit at CES 2016.
According to the spec sheet, the working area is only 300x300mm but it is capable of cutting up to 6mm aluminum, and 4mm thick steel or titanium. The operating pressure is a whopping 17,000 PSI or 1200 bar. We want one.
