So far so good – we have the scanner base and the vertical arcs.
The turntable consists of 12 pieces of a circle, 30 degrees each, and with a 3mm thickness overall and a 6mm edge and center.

Now that the scanning works, it’s time to explain the design of the tool. The size of the finished system of course makes it impossible to print it with any current 3D printer available to me, but even with MiniFactory’s 15 x 15 cm build table, it is doable. I wanted to have a 30 cm diameter turntable, and a 60 cm diameter frame base so as to have space to shoot objects bigger than 15 x 15 x 15 cm. The turntable is printed in 12 parts, assembled with screws, just like the arcs. I didn’t want to use glue, even if ABS is easy to build with glue. There are a couple of other parts too, like the cup below the turntable on which it revolves, and the three vertical arc mounts. There is a small triangular part at the top to assist in fixing the top arcs together, and that is done with a bundle strap. It’s easier than using screws and works just as well.
I modeled all parts in Blender, exported to STL and printed on my three Minifactories. I wanted to keep the design as simple as possible, and recycle parts so as not to have to change the printing setup every time a part was finished. Therefore the base arc and the three vertical arcs are of the same parts, and as ABS flexes a little, the whole setup can be put together and held in position by a single bundle strap at the top of the arcs. Let’s see the parts in detail.

I’ve been a little busy lately, what with the new curriculum at Haaga-Helia being introduced and whatnot, but I’ve also managed to do something I have wondered about for a while already. I found a piece of software, Autodesk’s 123D Catch, and it seems to work really well with my pet project, the 3D printed 3D scanner system. Now that the printing department of the 3D Lab works well, with the 3 Minifactories and one CoLiDo Printrite, it’s time to take the next step.
