Built on optimized algorithms and carbide cutting tip, Mcor IRIS HD makes crisp, full-color detail and text on 3D printed models to deliver photorealistic appearance around full geometry of model. Unit creates complex, durable, and stable physical 3D models from layers of paper printed with ink and bonded together. Models can be tapped, threaded, hinged, and made water-resistant and flexible. Users can print hollows and moving parts, and recycle used models for cradle-to-grave sustainability.
