nScrypt Launches Ruggedized Precision 3D Printer/Bioprinter

nScrypt is now launching the nRugged, a precision 3D printing/bioprinting platform for harsh environments. nRugged is a ruggedized version of nScrypt's digital manufacturing platform (Factory in a Tool or FIT), which can be configured for 3D manufacturing or bioprinting in harsh environments, and can do both with automatic tool changes programmed into the build.

The machine can be outfitted with up to four tool heads, in any combination, for microdispensing, material extrusion, milling and polishing, and pick-and-place, using 10,000+ material choices. The standard machine sports a carbon fiber exoskeleton and 150x150-mm heated print bed, and prints 238 mm in the X axis, 173 mm in the Y axis and 152 mm in the Z axis, but can be built in other sizes. Optional equipment includes a target view camera (for microscopy and X-Y alignment) and a process view camera (for a live view of the printing tip) for in-process monitoring and control, a Keyence line scanner or point sensor, and a four-channel heater controller. No external compressed air is required.

The bioprinter configuration can print both biologics and non-biologics. For example, the ABAT version of nRugged recently printed a scalpel handle and hemostat, bioactive bandages with a hydrogel layer containing antibiotics over a flexible structural layer, a surgical model of T9 vertebrae, and a bioprinted meniscus comprised of live mesenchymal stem/stromal cells and a hydrogel scaffold, in a forward-deployed desert environment, in successive builds with automatic tool changes and a broad palette of materials, according to the company.

Setting up the nRugged printer is almost instantaneous. Its integral packing crate on wheels allows the user to roll the machine to where it is needed, remove the crate lid, plug together the printer, battery case and electronics case, and start printing. Calibration is automatic and near instantaneous, the company reports.

“nRugged is so much more than a 3D printer,” says Dr. Ken Church, nScrypt's CEO. “Because it is a version of our Factory in a Tool, it solves the problem of building a precision product, not just a part, and does it in harsh environments. The real advantage of this tough machine is mobility, rapid mobility, while maintaining precision.”

The nRugged runs on 24-28VDC power or 100-240VAC power and can run for up to 48 hours with the battery option, which can be solar charged. The machine and integral crate, which weigh about 220 lbs. (depending on the configuration and options), can be lifted and moved by three or four people and pushed by one person.

The nRugged is available for sale now.
