Towards a Pancake Printer

I love Kickstarter and have backed a lot of things on there, one or two of which have been great. But often the projects take longer than expected to complete and are a little underwhelming when they finally arrive.

I’ve noticed recently two pancake printers (here and here) on Kickstarter and, this time, rather than backing the one that is actually a product (is $299 really a reasonable price for a printer of pancakes?), I thought I’d have a go at making one.

Rather than go for a conventional XY plotter (which wouldn’t work well with a conventional pancake pan on a hob) I’ve been looking at SCARA robots like the one using in this great project.  SCARA robots are more like human arms working in a horizontal plane. The Plotclock uses two arms working together to hold the marker – so a bit like holding your hands together and using your shoulders and elbows to draw with a huge pen.

To make a start I decided to simulate the area that I could draw with this kind of robot using D3. I started with a nice simulation showing the relationship between a circle and a sine wave.

And I made my own simulation of a SCARA robot on JSFiddle.

    NFire 1 – Worlds First Truly Modular 3D Printer- I think This printers delta robot axis has greater potential for scaling than the traditional X Y Z machines. Already we have aerospace printers capable of printing directly with hot metal larger than 5 metre cubes. Installation of large CNC machines of 30 Metres or more is difficult. Consider how you maintain perpendicular X Y Z axis on a 30M concrete base within 100 micrometre? Or perpendicular X Y Z in nanometrology I think the future for the very large and the very small could be with printers looking like the G&L Variax Hexapod Mill – 6 axis printing with positional information and without any attempt at straight axes in what I am calling a ” software controlled print cloud “
