Why Cool: OWL offers a precision stereolithography (SLA) printer that is not sold but provided with a service subscription, assuring buyers of upgrades as their printer is enhanced over time. The unique subscription plan provides combinations of maintenance services, technical support, operator training and consulting. The business model is intriguing — I often tell our clients to “try before they buy” a 3D printer.
The printer itself incorporates patented, proprietary technology encompassing different lasers, materials and mechanisms than used by other SLA printers. OWL says its MC-1 printer offers repeatable 1-micron resolution and accuracy to +/- 500 nanometers. As a practical matter, a 4 millimeter (diameter) micro gear, such as the one in Figure 4, is an example of the smallest size part the printer can make.
