Mcor Technologies, Dunleer, Ireland, has introduced the IRIS color 3D printer that prints in more than one million hues simultaneously, creating photorealistic physical objects from 3D data. The IRIS delivers True Colour, printing different hues simultaneously, including pure black. The machine’s build material is standard Letter/A4 size paper, either new or used. The IRIS’s patented 3D color ink permeates the entire part, not just the surface, resulting in printabilty on all surfaces, including undercuts and sidewalls. Models can be disposed of in the recycling bin for cradle-to-grave sustainability. When pages are cut and bound together, the model is tough, durable, and stable, with no infiltration required. The printer employs water-based adhesive, eliminating toxic fumes, lasers, airborne powders, or toxic resins. Color resolution is 5760 × 1440 × 508 dpi, and machine resolution is 0.004". File formats for printing include STL, OBJ, and VRML, and the system is compatible with Windows XP, Windows Vista, and Windows 7.
