I thought to try a small job with the 1/8" Grey Acrylic from Inventables. The large photo shows an old instrument panel with functional MFD’s for a large scale RC EuroFighter Jet.
The smaller pic is one of the new MFD button arrays that I did on my GF this morning. I used a vector drawing which uses four different colors. The buttons are done in a two stage approach. I duplicated the buttons twice then assigned different colors for engrave and cut ordering. First I peeled away the backing from the plastic. I then engraved the buttons using 140-8 After the engrave the button perimeters are scored with 305-20. Then the inner panel is cut out with 200-full and the same for the outer panel.
The buttons are not perfect but I can easily apply a drop of epoxy resin to each so that it flows out flat. I then make a silicone mold so that I can mass produce them.
I was quite impressed with the outcome for my first attempt. Once these MFD’s are attached to the main instrument panel I then use small LCD’s to animate the actual functions of the real aircraft.
Now if only my GF would stop scanning so that I can do another batch. Its stuck now for ten minutes scanning si will have to start all over again…
