We have moved to Japan!

5U0A8634

Good news, everyone! Schorsch is now living and working at OIST, Okinawa, Japan. Don’t worry about his wooden body, the Lab he’s in has a nice dry atmosphere and he shares it with a lot of far more expensive stuff. So far he’s doing a good job, but the fancy new place with ocean view has a steady cold breeze from the AC above so i will have to do something about that.

He survived the 14hrs+ in a plane with minor injuries on Z. Luckily the parts that broke were meant to break in case of failure and i am quite proud that there were no further problems due to the loose, rocking Z-axis. X and Y arrived fully working, even the lines haven’t jumped off any bearing.  Remember to fix EVERY part that can move when you put your Printer on an international trip!

 

Update: Science!

Dipol-Cluster_01

This is a cluster of eight dipoles. I did not thought about this until a few months ago when a friend came up with this at christmas. He told me that it would help him at work. So here it is! In this case the dipoles are represented by Toy-Magnets i had laying around. Each magnet sits in its own gimbal allowing free rotation around its centerpoint which is one corner of a 40mm X 40mm X 40mm cube. Manipulating one magnet forces the other ones to align. This is as fascinating as it is hard for me to explain. But don’t worry, Dr. Johannes Schönke will have a look at it.

(The screws in the picture might trigger some trolls. They are made of the least ferromagnetic stainless steel I found. But of course, there shouldn’t be any ferromagnetic part.)

Schorsch is [printing sth. that is] going near space!

ROCKET_Tip01Recently, a guy named Karl called me with his idea of building a Model-Rocket in order to start his new life in Rocketscience.

He already had everything but the cap so he sent me a Rhino-file with his calculated shape and now we have a few Caps that should make the Rocket go about 500m high. Above you can see the tip right out of the printer (left) and after sanding/acetoning (center, right). It is about 2.4g for the cone and another 1.2 for the bottom. After sanding and acetoning the should be 3.4g in total for the tip. Not that bad – with a .3mm nozzle they could weight around 2g at all!

Maybe the future will bring us some lower restrictions here in Germany so that we can use stronger Motors to lift something more than a few hundred meters…
