The use of contemporary technologies of Computer Assisted Design (CAD), combined with latest rapid prototyping, tooling and manufacturing, with traditional CT scanning techniques and high medical skills are used as instruments for better diagnostic visualization, simulation of procedures and treatment of patients with craniofacial deformities. They also improve the overall performances of medical and nursing staff thus influencing the quality of medical service. Patients with congenital defects, orthognathic deformities, deformities after malignancy treatment or after craniofacial traumatic injuries of different severities are of particular interests due to both aesthetic and functional alterations. The paper presents two clinical cases - a patient with scull bone defect after brain hemorrhage and brain edema as well as a patient with hemifacial microsomia treated by surgery followed by implantation of titanium angular implant prepared by means of computer tomography scans, Computer...

In the last decades, the technical field of additive layered manufacturing (ALM) has offered aid in medical reconstruction procedures in order to help surgeons reconstruct physical faults and anomalies of their patients. Using a combination of Computer Assisted Design (CAD), high medical skills and latest ALM technologies, it is now possible to help patients with birth defects or those suffering from craniofacial injuries of variable severities, retain aesthetic and functional properties of their bodies. Combined with traditional CT scanning techniques rapid technologies (prototyping and tooling) can be used as instruments for better (three-dimensional) visualization, simulation of procedures and treatment of patients. They also improve the overall performances of medical and nursing staff thus influencing the quality of medical service. Using a combination of Computer Assisted Design (CAD), high medical skills and latest rapid prototyping and manufacturing technologies, it is now p...

n Introduction The textile printing market recorded a to-tal production of around 25 billion m 2 of printed fabrics for 1996. As a dominant textile printing method, rotary screen printing represents 61% of the total production of printed textiles [1-2]. The increasing demand for environmental protection, short process runs, quick re-sponse times, and mass customisation in the textile industry has increased interest in ink-jet printing technology [3]. Abstract In this work, a collection of decorative textiles for home furnishing was designed on a CAD CAM system, printed with an ink-jet printer, and transferred into production using rotary screen printing. The basic materials used were linen woven fabric and reactive dyes. Colorimetric measurements were carried out for the samples printed with both printing procedures. The reflectance values, CIELAB colour values and ΔE* colour difference values were obtained and compared using two spectrophotometers. The colour fastness of the printe...
