I did some experiments this evening with the new 3D printer. This will be used for making propellers but this evening I decided to try and make some propeller nose piece (hubs).

I was pretty impressed. I cooked up a couple of hob designs in a CAD program and then ran it through the machine. Now that it appears to be working nicely I will add some down thrust and some landing gear fastening system. Once that works I’ll see what I can do to minimize plastic use.

This material is PLA (Polylactic Acid). PLA is a biodegradable thermoplastic that has been derived from renewable resources such as corn starch and sugar canes. This makes PLA environmentally friendly and very safe to work with.
