Introducing the AxiDraw V3

We are pleased to introduce the AxiDraw V3, a new generation of our flagship writing and drawing machine.

This new AxiDraw has been redesigned from the ground up for high performance. It features smooth rolling wheels on custom aluminum extrusions, specially designed for high stiffness and light weight. Its sturdy, rigid construction gives it finer quality output and in most applications allows it to operate at up to twice the speed of the previous AxiDraw, which it replaces.

As with the previous version, AxiDraw is a simple, modern, precise, and versatile pen plotter, capable of writing or drawing on almost any flat surface. It can write with fountain pens, permanent markers, and other writing implements to handle an endless variety of applications. Its unique design features a writing head that extends beyond the body of the machine, making it possible to draw on objects bigger than the machine itself.
