The scaffolds fabricated were subjected to series of examinations using microscopic and spectroscopic techniques. The data concerning a virtual 3D porous implant model was transferred into a SLM device and a scaffold was produced from metallic and/or ceramic powders with this machine. height, depth and width, they are duplicated with appropriate mathematical algorithms as a result of which a strictly defined, densed and complicated structure of pores defined by a designer is created. Once the shape is defined of a unit cell and its net parameters, i.e.
The real manufacturing process of a scaffold is preceded with creating a model of an element in the stl format that allows to present the element surface by means of a net of triangles. Scaffolds are produced with biocompatible materials that can be employed for a long time in an organism or may be subject to gradual degradation and resorption. The goal of the carried out research is to fabricate, by selective laser melting (SLM), a metallic and/or ceramic scaffold based on a virtual model corresponding to the actual loss of a patient's craniofacial bone.
For this reason, these technologies have been characterized in detail on the basis of available literature sources. Originality/value: According to augmented holistic Industry 4.0 model, many materials processing technologies and among them conventional powder engineering technologies play a key role in current industry development. Findings: In addition to the presentation of conventional sintering technological methods, sintering mechanisms in solid-state and liquid phase sintering which accounts for 90% of the commercial value of sintered products are presented. By using knowledge engineering methods, development perspectives of individual technologies were indicated. Design/methodology/approach: Extensive literature studies on conventional powder engineering technologies have been carried out. Development perspectives of the most widespread among them were indicated. Based on a comprehensive literature review, conventional technologies using the powders of metals, their alloys and ceramics are described. Purpose: Among the technologies that play a crucial role in the current stage of development of Industry 4.0 conventional powder engineering technologies are of great importance.
#Deadlock coatings code#
SWZ has been enhanced with a module generating files containing the script code of the system model using the internal language of simulation and visualization system. Furthermore the example of SWZ and simulation system integration is shown.
SWZ also allows to generate the dispatching rules as a sequence of processing operations for each production resource, performed periodically during the production flow in the system. The obtained results allowing the determination of acceptable production flow in the system - determination of the manufacturing system parameters those that ensure execution of orders in time under the resource constraints. In the paper examples of the application of SWZ system comprising the steps of planning and control is presented. Fulfilment of all the conditions (the conjunction) provides the ability to perform production orders. The methodology uses the propagation of constraints techniques and reduced to test a sequence of arbitrarily selected conditions. SWZ (System of order verification) is a computer implementation of the methodology that support fast decision making on the acceptability of a production order, which allows to determine not the best possible solution, but admissible solution that is possible to find in an acceptable time (feasible solution) and acceptable due to the existing constraints.
