Random thoughts on hot-end design

I spent some time modding the bfb hot-end. Originally the hot end is very sturdy but with extremely soft filament (soft-abs from orbi for example) it is not able to print at low speeds (0.25mm layer 16mm/sec was on the limit, working but not consistent, 0.15mm layer 16mm/sec killed it)...

3D printing and "Intellectual Property"

A while ago a few of us wrote a paper:

on the "IP" implications of home 3D printing.  This looked at the matter mainly from the UK and EU perspective.

Inspired by that, Public Knowledge, a Washington DC based public interest group, has now put out a white paper on the same questions from a US perspective.  You can access it here:

The Gada Prize

We are pleased to announce that Humanity+ has taken over the hosting of both the Initial and the Grand Gada Prize for Personal Manufacturing.

These prizes are offered for free and open-source RepRap machines that are significant improvements over the current generation of machines.

To stand a chance of winning you have to register your intention of entering and to publish your developments regularly - we all wanted to make sure that the prizes didn't drive people to develop work in secret, as that would be the exact opposite of what RepRap stands for.

Seventeen teams and individuals have already entered. Entry is free.  It is also still open, and will be for quite a while.

So why not have a go!
