Many of us have heard of 3d printing, and i certainly have, since i have just purchased a 3d printer with a considerably large print area. 3D printing has been used for quite some time now, but until recently, was not available to the average consumer willing to purchase one. Here, in the NBTVA, you might have seen the 3d printed 52 mm hub for connecting nipkow disc to motor shafts in club sales, or the 3d printed mirror drum project in the news letter, which i have been taking part in, printing around the figure of 4 mirror drums, all of them slightly different. In-fact, what prompted me to write this post was the completion of a new mirror drum a few minutes ago! But, in my mind, the most important part of 3d printing for the club, would be reproduction of replacement parts for building models of radio chassis, chassis for televisions of any era, or even complete radios themselves, which i have been trying to do, building a scale cabinet for a Baird radio receiver, and printing it with wood infused filament, and printing a circuit board, now possible with the event of electrically conductive plastic filament. I have even printed microphone cases, modeled to resemble the microphones used by the BBC in the late 1920's to the mid 1930's, and have put a little hole in them to insert an ordinary carbon button microphone out of a telephone handset. End of rant.
Also, i will be posting a few .STL files for models that i have produced myself, such as the BBC microphone, later in this topic.
