Perhaps it has something to do with the fact that they have swindled over a million USD for a glue gun which you can assemble at home in 20 minutes. Sure, people can spend their money on whatever they want but it doesn't make it any less ridiculous.

You're making the assumption that everyone in the world is capable of or would even want to assemble a crude version of the same concept at home. Comparing the resourcefulness or ingenuity of an experienced hacker to that of the product's target market (artists, crafters and children) is asinine at best.

It is exactly this kind of overreaction that I was addressing in my original comment. You make these wild assumptions that it's only going to cost them pennies per unit to manufacture and that they're ripping people off. But that's far from reality.

Swindled?

Seriously?

[jrogers65]

If I sell someone a sheet of A4 paper for $100, have I not swindled them?

[notmarkus]

Unless you lie and tell them that it's something other than a sheet of A4 paper, no, you haven't swindled them. You sold a sheet of A4 paper at the price that someone was willing to pay.

Which is exactly what has happened here on two counts -

1) it is not a world first - http://www.thingiverse.com/thing:4156

2) it is not a 3D printing pen, it's just an extruder - exactly the same mechanism as that used in a glue gun.

1. The item on thingiverse isn't referred to as a 3D pen.

2. Extrusion is the mechanism through which most 3D printing works. In this case, the extruder is attached to your arm rather than to a machine.
