Pocket Sprockets

Well I've had bumper Friday of exciting things coming in the post today, first up here are my very first 3D printed objects. I present 2xDIY 8mm film sprockets. I only sent these to Shapeways.com on Monday night, and here they are in Friday's post! Much quicker than the 10 days Shapeways quote for turnaround time. I think it's pretty impressive that one can design a custom item and have it manufactured and returned within the same week. Here are the little fellas...

Now these are tiny, the hole in the centre of these is only 2mm in diameter, so you get some idea of just how tiny these are. I wanted to test the process with something small. Well I'm pretty impressed these came back, with all the features intact; maybe without the sharpness in definition I had hoped for. There 's no sign of the layering effect one sometimes sees in 3D prints, but there is a 'grainy' or slightly 'powdery' feel to these; they aren't smooth to the touch.

It remains to be seen whether my design and the manufacturing are fit for the intended purpose...

Ok, these just don't seem to engage the film sprocket holes at all. It seems the 3D printed sprockets are just too big and fat to fit in the holes... However, I've just noticed that Shapeways offer a 'fine detail' plastic material that's 'slightly shiny'; that sound more like what I'm after. I think I'll redesign a bit on 123D Design and send off another print job soon.
