Hi,
A small example of a hybrid approach for 3D printed parts of my heli. Some parts need to be resilient and at the same time to have a high level of detail.
This was the case for the upper cable cutter of the Jet Ranger. This model (AB-206B)ncarries a quite long cable cutter. In order to reproduce this part I used the Z-Ultrat material on my Zortrax M200. This is a wonderful material, very stable, resilient and very easy to sand and glue. On the other hand, although the Zortrax M200 can reproduce a high level of detail, it is still difficult to 3D print small details on the parts.
High level of detail can be achieved with SLA 3D printing. My customized mUVe3D comes into play now. Already with around 70μm in-plane resolution the mUVe3D can reproduce fine details like small nuts and bolts of less than 1mm in diameter.
Now if we combine the two 3D printing methods we can print the main body of the cable cutter with the Zortrax M200 and the small nuts and bolts with the mUVe3D (put on a very thin raft shaped as and glued upon the underlying part that is printed with Z-Ultrat). The pictures speak for themselves.
While working on the helicopter I have many times accidentally pushed or pulled the cutter. It bent but it didn't break. A resin-printed part is not that resilient and it would have certainly broken.
More to come in the next days.
Cheers
