Tethon 3D Acquires Fortify IP to Target RF and Defense Applications

Tethon 3D has acquired Fortify’s advanced materials intellectual property. Fortify wanted to bring fiber-reinforced vat-polymerized parts to market before pivoting to electronics and later to RF applications. This got them $12 million in funding from Lockheed Martin, followed by a joint investment from Raytheon and Lockheed. The firm sold a 3D printer to NASA’s Glenn Research Center, but things have been quiet around Fortify of late. It’s a shame because, whereas the firm initially made a rather diffuse and confused market entry, the RF 3D printing materials bet was prescient.
