Inspired by beetles and fabricated by a robot, this striking garden pavilion kicks off the Engineering Season.
V&A.
I made this gizmo to observe and study filament as it melts and moves through the extrusion process. The barrel is made of boro glass (aka Pyrex). It works pretty well but as you can see there is a leak between the glass barrel and the brass nozzle. Any suggestions on how to seal this 220C joint?
testing some ABS from 3D Universe - worked great! These are printed on an Ultimaker 2+ Extended in ABS, 0.1mm layer height and a 0.4mm nozzle.
A huge filament I had the chance to image a few days earlier
It keep the same basic shape but developes nicely
To show how big is this filament I added Earth in scaled size.

This morning the weather report said we might get "some snow." Well, from inside, the flakes were so fine you could hardly see them falling. I went out on my deck and let some of it fall on my shirt and noticed that I could see actual 6-pointed crystals!
I looked around and saw the most amazing sight. Numerous tiny snow crystals had fallen on a spider's web attached to my lavender plant and were suspended in mid air by the ultra-fine spiderweb filaments. My camera isn't good enough to capture the web itself, but the suspended snow flakes looked ethereal and other-worldly.
Can't wait to get a better camera so I can take better photos of subjects as magical as this, and have them look good!
This is the eastern portion the Veil Nebula, NGC6992. These glowing filaments of shocked gas are part of a larger spherical supernova remnant (known as the Cygnus Loop or Veil Nebula) -- expanding debris from a star which exploded over 5,000 years ago. Seen from our perspective against a particularly rich part of the Milky Way star field, the Veil lies ~1,400 ly away. At that distance, witnesses to the original stellar explosion would have seen a star in the heavens increase in brightness to about -8 magnitude, roughly corresponding to the brightness of the crescent Moon.
