Two college students invented an adapter that allows 3D printers to print in full color for less than $100

Recommended Posts

You can make some nice vases with that. I'm more the black / white type though o.O

This can also be done a lot easier (not that good, but it works) by feeding multiple strands of PLA into one hotend, with multiple extruders and Bowden tubes. Somewhere on the forum there was a thread about that. Would be much easier to build and maintain (no dyes needed - what will the dyes cost, anyways?). It's even possible to actually blend different colors together.

Right, I think it was called something with "blend" in it...

I guess the main reason for using this kit is not in creating multi-colored objects - but in creating an object in a single color, exactly the color that fits the purpose of the object. I.e. a vase that is not blue or pink, but a tone that fits your interior. Or a replacement part for something, with exactly the same color as the original.

Cool! I would buy one if it is as good as predicted. The real advantage is you don´t need that many spools of filament anymore and you can change between colors without changing the filament. I have about 2 spools of different filaments laying around. And they don´t get better over time...

You will only get pastel colors at best, because the color is only applied to the outside of the filament.

You can try it out for free - use some sticky tape to create an "adapter" or hold one or more felt-tip markers against the filament before it goes into the machine. Note that the marker dries out fairly quickly since it is exposed to the air the whole time.

You could easily design and print an adapter to hold the markers in place...

    • Architect Design Contest | People
      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
