I found this kind of flexure mechanism from internet yesterday and wanted to try print one. So I made a CAD-model and printed it out. Thinnest walls are only 0.5mm thick and it’s printed with 0.25mm nozzle so they have still two perimeters.
It turned out suprisingly well! I can get very precise movement out of it. 5mm motion in lever makes 0.25mm motion in dial indicator.

Would you mind sharing the cad files? 
That’s an impressive bit of 3d printing. The lever is your friend.
@Markus_Granberg I uploaded it to the thingiverse: http://www.thingiverse.com/thing:1424169
@Mark_Rehorst This was simply to test if it’s possible to make this! There isn’t a lot of information in internet about this kind of flexures…
What do you thing would be the result if the parts were modified to permit a 0.40 nozzle? That would kick the thin part out to 0.80, yes? Too much rigidity?
@Fred_U Yes, the thin part would be 0.8mm. It’s hard to tell but I guess it would still work. There isn’t so much bending after all.
@Topias_Korpi it’s so cool that this works.
And yes to flexures you don’t find much in the internet.
I was looking to 
Because I play a bit with homebuilt microscope and spectroscope.
You can find a bit of info on flexures in MEMS work. The accelerometers and gyros in your phone are a good example.
@Mark_Fuller also around themes like seismographs, Linearmotors(special around the voicecoil types) modern cameras like the one you find in smartphones.
Piezos are also often combined with flexures
@Mark_Fuller Very interesting applications! I guess these are mostly used as “shock absorber” rather than motion producing? At least in MEMS.
@Sebastian_Schmidt Do you have any photos or writings of your microscope online? I’d be interested to see those mechanics!
a compliant structure… ok. the’re used in MEMS and MOEMS to amplify displacements. since they are made as integral structures, there is no backlash. the actuator is soldered in place and that’s that.
A google search gives a lot of good ideas what can be done.
