No. BD3D2MK3D converts from the BD3D format (AVC+MVC) to side-by-side, top & bottom or frame sequential format, encoded with the AVC codec (x264) or if you prefer HEVC (x265). Since that conversion requires to re-encode the video, it compresses it as well (more or less, depending of your encoding parameters). SBS and T&B are the most useful formats, because they are recognised by all 3D players. Frame Sequential is recognised by some players (notably DLP projectors) and is recommended only if your player doesn't support SBS or T&B.

In the other hand, recompressing to the same BD3D format (AVC + MVC) doesn't make much sense, except if you want to re-create a 3DBD with smaller files (such as for burning the movie only on a DVD formatted in BD format). To compress to the BD3D format, you need a "twin encoder", to create the AVC stream for the main view, and the MVC stream for the dependent view. And encoding to MVC is not possible with x264 or x265. To do that, you need an encoder based on the Intel toolkit (the only available free MVC encoder), such as FRIM. That encoder gives less good results than x264.

The third solution is to put the original AVC and MVC streams without re-encoding them into a MKV container with MakeMKV, to create the so called MVC MKV. Currently, only stereoscopic player can easily play that kind of MKV, so the only advantage of that format is that it's a good backup of the original BD. But it takes much disc space and is almost unplayable. You can save much disc space if you re-encode the AVC and MVC streams with FRIM, but what's the point? You'll get a too poor quality for a backup, and the MKV will still be playable only by Stereoscopic Player. Anyway, it's something BD3D2MK3D doesn't do.

Use the right tool to do what you want. Good quality SBS, T&B or FS in AVC or HEVC with BD3D2MK3D, or AVC+MVC with FRIM Encoder and a 3DBD authoring program is you want to compress the 3DBD to another 3DBD or create an almost useless MVC MKV.
