This is very interesting. I have a collection of the original Inkjet printer hardware and wanted to put it in a museum. www.layergrownmodel.com to see a video of the printer from early 1990's.
Would you be interested in working together to show these things to the public? It is really great you found this. I was asking if there was a first model off off the original .STL printer we hear so much about from Charles Hull but no one has shown it to me yet. Now we have two of the competitor technologies from that early era.
