I'm posting this here because I think it is a genuine advance in 3d printing and because is is a singularly impressive piece of work.

This guy,  Joshua Bird, has written the hardest part of a 3d slicer for non-planar printing.

Planar printing is the typical flat layer by layer that pretty much all printers have used to date.
Non-planer allows an object to be printed with minimal supports and allows better layer orientation for stronger parts.

Prior to Joshua's work, non-planar print tool paths had to be mostly had coded or simplified to multiple planes.

Hi folks,
A shorth week due to a trip to York on Friday, but we get stuck into the mini D
type, get the body off and get the engine layout sorted and fitted as far as the drive mechanism is concerned, when I get chain and sprockets finished I want to put the body back on to finalise the engine position. I get some more sorting out and spring cleaning done in the workshop, and a lot more items for sale photographed and listed. Sales have been made already!!

Cheater lenses come in a range of magnifications but are widedly available on the web - here is an example:

Certainly the leather flap made a big difference when I fitted it.

cool! 

I think I mentioned that the original intention was to run this little engine on wood. I wish I'd had the time when I first built it to make that possible.

Today I started making a little latch for the fire door on the firebox. I also began insulating the firebox. It will be insulated just like my melting furnace, but on a tiny model scale.

Here I've fitted a layer of fiber insulation to start with:
