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.
A Klein bottle only makes sense if it’s transparent so you can see what’s going on inside. Not that easy to make transparent/translucent 3D prints. Here you can see 3 different Klein bottle prints using an Anet A6 3D printer and Rigid.Ink Trans Blue PLA filament.
The leftmost bottle is a 0.8mm solid double-wall print – even back-illuminated you cannot see what is going on inside.
For the middle Klein bottle – I have cheated. That is a 0.8mm solid double-wall print of a half Klein bottle – the bottle has effectively been cut right through the middle, at least that way it is clear what is going on inside.
The right-hand Klein bottle is a 0.8mm SINGLE-WALLED print! Being translucent you can at least see what is going on inside.
I think we need a 3D glass printer to get what I’m really after.
The longest print I have made to date! This is a 115-hour print of a 4th order Menger Sponge 122mm on a side. Printed on an Anet A6 3D printer using Rigid.Ink white PLA.
I’m not sure if I will go for a longer print time than this again, it was a pretty nerve-wracking experience, particularly once it exceeded the 100-hours.
