One hundred microns is fairly standard for current desktop 3D printers, so we had to do a double-take when Old World Laboratories (OWL) announced they were bringing a 100 nanometer 3D printer to the prosumer/consumer market. If we convert the OWL Nano’s 100 nanometer print resolution into microns we get 0.1 microns, 1000 times more accurate than standard 3D printers and 100 times more than its intended competition.

At this point you’re probably wondering how OWL has achieved such a high resolution. According to the company they have used stereolithography (SLA) technology, which uses a laser beam to fuse/solidify UV curable material into layers. We’ve seen this technology used on a number of 3D printers already, but OWL’s Nano differs from other SLA printers by its use of the laser. Rather than using mirrors to bounce a laser beam onto the correct point, OWL positions its laser source just centimeters away from the structure.

OWL says their laser positioning brings about a number of benefits, “This decreases beam distortion and allows the highly tuned, single strand laser to focus on an area as small as 100 nanometers. The OWL Nano’s laser also maintains a perfect perpendicular position below the object it is forming, which creates a more balanced 3D print.” “In addition, it also minimizes fumes – eliminating the need for additional room ventilation – and helps stabilize operating temperature.”
