Crayon printer

create crayons in any color

This device would consist of:

A wax reservoir containing translucent wax
Four pigment reservoirs
wax melter/mixer with pigment injection
A low powered press for forcing the wax through a hole.
A single pixel/24 color display
A numerical keypad with a "make it" button
A simple internal computer control device
A simple label printer capable of printing out the new crayon's color in RRGGBB format, with two additional notations for how dark the new crayon is.
A label hopper containing labels with a water-activated glue strip down one side.

The purpose and combination of these items is, I think, obvious.

       Instead of one wax reservoir and four pigments, why not just have four reservoirs of coloured waxes (red, green, blue and black)?

       Ah, hang on - white will be a problem.

       I thought this would use 3D printer technology to allow making a crayon in any shape.   

       As described your idea is just a highly automated version of the Crayola Crayon Maker.

       And yellow

       You mean this is not a plotter that uses Crayons? Oh...too bad.
normzone, Oct 03 2014
  

       The Crayola Crayon Maker is not good. It is small, slow and makes little crayons with inferior molds. What is needed is a teflon coated oven pan with crayon shaped molds for serious crayon recycling. I am so surprised that molds of this sort are not sold. Lots of teachers would recycle their crayons.

       The addition of a white wax would solve this problem. I like your idea better.

       And I thought this would be about a printer that USES crayons....

       Got three buns for you...is there like a paypal for buns?

       Waves a hearty hello to [senatorjam], your link comes very close to this. But a substantial idea anyway. Hey where you been jam man?

       I thought that was Granola...   

       Looking at the "solid" ink printer blurb....it's a big girly fib. It melts the ink to print and needs a vacuum pump to debung ink from the printhead at the end of a print run.   

       Crayon, crayons, crayons!
