Hi all,

Currently the thinnest single wall I can print with a 0.4mm nozzle, in ABS, is 0.48mm regardless of layer height (Upgraded Replicator 2X).

This is way beyond my original expectations; however I would like to know how far I can push it.

Ideally I was hoping someone could recommend a 0.3mm / 0.2mm nozzle supplier. Obviously I have had a look on eBay, but would prefer a recommendation - some of the Chinese nozzles don’t look the best of quality.

I’m working on the ducting for a Micro EDF Hawker Hunter RC Jet and need to get the weight of the printed parts as low as possible.

To give you some idea the pictures below are of the first printed prototype ducting and will be used to test the thrust & drivetrain etc.

Cheers, Steve

I love the use of 3d printers in rc hobbies. Your ducted design looks very nice but my understating of ducted fans is you need the intake to start of large volume then tapper down to increase air velocity. It looks like your design might increase in volume after the intake. Looking forward to reading some more on your progress.

@Tim_Rastall Thanks for the link Tim.

@Mr_covert It’s deceiving as I have actual designed them to be constant area for the inlet & only taper to 85% Fan Swept Area at the exhaust nozzle. If you are interested you can follow the build on RC Groups - http://www.rcgroups.com/forums/showthread.php?t=2085592
