3D printed prototype of MessnerMoto Brake/Clutch Master Cylinder

We finally got our hands on the prototype of our Master Cylinder. Prototype is 3D laser sintered(SLS) in PA12 plastic. There are 40 parts in hole assembly. Some parts are just several mm big.

All the parts came out almost perfect from 3D printing. The only problem was in 3D printed threads, but that was expected because the smallest thread in assembly is M3. We simply corrected all the threads and thread holes.

The most amazing thing is that 3D printed PA12 prototype is almost usable. PA12 is really strong and durable material even when sintered in SLS process.
