Just an idea, but is it possible to have 2 liquid substances that
solidify outside the print head? Or 2 substances of enough viscosity
that they don't clog the print heads but at a certain temperature and
in contact with each other, they solidify?

On another note, addressing this whole "what is DiyBio Wikipedia"
controversy, let me suggest that you all work experiments out and in
the future, we can determine if it was DIYbio or not. History is
written after the event, and then it is analyzed and rewritten many
times. Just do experiments and take lots of notes.
