Hi,

dont know if this thread is dead... maybe this post will bring it back to life.

I invented a new type of cold end, it does not use a hobbed bolt but a belt. I hope it will inspire a whole new type of extruders, called v-struders

One of my first customers, a goldsmid, has let me know that he was able to print without any problems with a 0.1mm nozzle using moldlay wax filament. Im now searching for a place to buy a 0.1mm nozzle or even smaller so I can confirm this myself. Anyone knows a good webshop, preferably with fast shipping?

To this moment I was only able to test the v-struder with a 0.4mm E3D nozzle. In an extrusion only test, using petg 1.75mm at 235 degrees celcius I was able to extrude up to 2 meters per minute of raw filament without any slip in a bowden configuration with a bowden tube of 1 meter long.

You can buy it here: https://reprapworld.com/?products_de...8#.Vpo9WlKGNoc

Happy printing,

Vaeder
