The Extruder is still under development, but there are already nice 3D print results.
We have created an extruder based on the design of Unfold. We have added a syringe holder and a few more parts to attach it to the printer.
We used a 0.5 mm, 1.2 mm and a 1.6 mm nozzle as an experiment. But we have 30 other different nozzles, so we will keep trying to get the right nozzle. We bought a set of different nozzles in order to experiment with different sizes and lengths of the nozzles. You could also buy a set of 50 pieces of one type of nozzle.
We have also been creating different mixes of the ceramic, but we think that we have found a good mix that is strong enough to make thin walls.
If you would like to build your own, you will need the following things:
– 6mm multiplex
– HeadV1 5D.stl (from unfold: thingiverse.com/thing:28018)
– Syringe Adapter Head (from unfold: thingiverse.com/thing:21074)
– 2x M3 30mm bolts & nuts
– 4x M3 25mm bolts
– Disposable feed screw (http://www.dosieren.de/en/shop/products/cat/consumables/pr/disposable-feed-screw.html)
– Dispense needle kit (http://www.dosieren.de/en/shop/products/details/cat/dosing-needles/pr/dispense-needle-kit.html)
The project is still under development, but the results are already very promising. More info about the project will be uploaded in the future.
