Hello guys,
First of all, congratulations to the developer for this dual extrusion upgrade for the UM2. I really appreciate your effort!
Now to my contribution for the contest. Some months ago, I started a build of an A330 home cockpit. Some years ago, I did not get the chance to become a real commercial pilot. As I am now an aerospace engineer I want to satisfy my desire to fly an airliner (only virtual).
The picture below shows the status of the cockpit (very basic until now). To save costs, I want to print most of the parts on my UM2. Because a lot of parts are visible or will be touched during the operation, a clean and smooth surface is a must. Therefore, a dual extrusion with the possibility to print PVA support would bring my project a step forward.
Two examples for my application:
1. Currently I can only control the aircraft via the pedals. But in the real A330 the ground steering is done with a so-called tiller. On Thingiverse is already a model of such a tiller available (http://www.thingiverse.com/thing:1592935). To realize a smooth surface, because you touch this every flight, I want to print this with PVA support.
2. The Flight Control Unit (FCU) which controls the autopilot is bought. It can be seen at the top of the main panel in the picture above. Unfortunately, the size of the knobs is far off and I want to replace them with some with real measurements. I already got a photo and the exact size from a real A330 pilot (photo below).
I think during my build I will have a lot of other applications for the dual extrusion.
Regards
Stephan
