Is there existing technology that would allow to rebuild DNA molecule from a digital file storing sequenced DNA?

If not, does there at least exist theory explaining how such device could be built?

Yes, in fact synthesizing short stretches of DNA and RNA is available through several commercial services. However this limited to tiny DNA fragments (say 120 base pairs or so). Longer sequences require custom laboratory work.

    $\begingroup$ @user137 While it's true that long sequences can be made, this most often requires 'manual' stitching of several smaller fragments. However, current technology can already generate fragments of a few 1000bp (see e.g. here) $\endgroup$ – Nicolai Mar 14 at 9:20

    $\begingroup$ Thousands of base pairs is trivially possible with current technology - it's an off-the-shelf order from many companies. Tens of thousands becomes tricky. More importantly, although the question doesn't specifically ask this, this could not be used to re-create extinct animals (other than perhaps bacteria) because among other things epigenetic information would be missing. $\endgroup$ – iayork Mar 14 at 12:08
