Abstract (EN): Special Issue Information Dear Colleagues, As one of the promising pillars in Industry 4.0, 3D printing or additive manufacturing (MA), an inverse path compared to well-developed subtractive manufacturing, has gradually evolved over the past 30 years, from the laboratory level to industrial applications. The versatility of 3D printing and the possibility of producing geometric shapes of unlimited complexity without the need for molds, are some of its great advantages over conventional subtractive manufacturing. This unique feature of MA—“modeling without mold”—results from a multidisciplinary approach that combines mechanical engineering, automation, software engineering, materials science, etc., brings new opportunities and challenges for future manufacturing. One of the major challenges comes from seeking a better relationship between the shape of the print head and the intrinsic rheology of the chosen ink, which can be either a polymeric filament, a ceramic paste or a functional ink. This duet limits the speed and quality of the 3D printing process. The numerical optimization of the flow process, considering the shape of the nozzle to maximize the printing speed, can help to overcome this barrier. We are pleased to invite you to contribute to this Special Issue aiming at gathering contributions that describe recent improvements on 3D printing techniques by optimizing either the rheological properties of the inks or the printing process itself. We look forward to receiving your contributions. Dr. Francisco José Galindo-Rosales Dr. Célio Bruno Pinto Fernandes Guest Editors
