Sierpinski Octahedron in blue sitting on top of a Menger Sponge in white.

My latest 40-hour print of a 3D mathematical object on the Anet A6 printer.  Now printing the first of 20 prints that will assemble into a remarkable object – and a first for me.

Ignoring Alexa top-left, this is the 3D print collection up to 24/09/2017

After 47-hours and 56-minutes this beauty was created from Rigid.Ink black pla on an Anet A6.

This is a Mandelbulb, 120mm high, at 0.2mm resolution.  Needs a bit of cleaning up, but you can see the general structure.

I will reprint this even larger using Rigid.Ink trans blue pla filament.

So here is the Digital Sundial – working for real – in the garden – between all the clouds.

Radio-Controlled clock next to it for accurate time.

The 3D print collection so far:

Here is a working 3D printed digital sundial showing the correct time in the New Forest Observatory garden.

Compass is to point the sundial North and protractor is to set the sundial angle to location latitude.

Digital Sundial??  Gotta be joking right??  Nope – some genius out there has created a 3D printable Digital Sundial with 20-minute resolution (at 0.1mm printing resolution).

It is a remarkable piece of work.

Only gripe is – it was 10:23 a.m. when I took the picture, not 10:20 a.m.  Just kidding – it’s remarkable!!

Here is a rather large 6th order Sierpinski sponge printed on the Anet A6 3D printer using Rigid.Ink white PLA.

All was going well 120-hours into the print – when I got a nozzle clog.  This meant the top portion of the pyramid didn’t get printed.

Luckily there are some pretty clever people on the 3D printer forums and one guy suggested I use Ideamaker to just select the missing bit of print and then print out the missing top section separately.  First attempt at doing this I didn’t choose a big enough section to reprint and it only just slightly didn’t fit.  Wanting a perfect fit I had a second go, this was in itself a 9-hour print just for the missing top bit – and fortunately this time all was o.k.

So here is the longest print to-date on the little Anet A6 – 129-hours on a Sierpinski sponge.
