In the process of design and product development, prototyping model is an important step to finalize the product. Rapid Prototyping (RP) is a technology of product synthesis layer deposition material. The method was developed in the early 1980s as a consequence of the enormous growth of automation systems design and technology (CAD / CAM). The prototype of a complex solid model to determine the final appearance of the product, evaluate the assemblability of products, etc.

“…The metallurgical processes occurring in the weldpool melt play the main role in the formation of a welded joint, which requires close control over the mechanical properties and structurization of weld metals. Therefore, application of modifiers in welding engineering takes on great significance [5][6][7]. The traditional methods for setting up an experiment generally involve description of all variables among observed correlated variables in terms of a potentially lower number of unknown variables, so-called factors.…”

The effect on the deposited metal structure of nanostructured modifiers introduced into the weldpool has been studied. Methods have been developed for determining the concentration of nanostructured powders of tungsten, molybdenum and Al2O3 in protective gas and for defining their optimal concentration. The influence of nanopowders on the structure of deposited metal was examined in consumable electrode arc welding employing the austenitic steel (chemical composition: C – 0,12%, Cr – 18%, Ni – 10%,Ti – 1%) as deposit and 1.2-mm welding wire manufactured from the austenitic steel (chemical composition: C – 0,12%, Cr – 18%, Ni – 9%,Ti – 1%). Addition of nanostructured powders of tungsten, molybdenum and Al2O3 to the weldpool has shown positive effect on the structure of metal in arc welding. It is shown that introducing the powders decreases dendrite size and leads to the formation of a more equilibrium microstructure of the weld.

This paper has presented the results of a study aiming to identify the effects of laser power and two other parameters on groove formation in ST52 steel using a fiber laser and to optimize these parameters so that the groove aspect ratio could be maximized. The Taguchi method has been used to explore the effects of three parameters, namely, laser power, scan speed, and frequency, on the laser grooving characteristics. The analysis has shown that the first parameter has a strong impact of about 69.95 %, while the other two have led to about 15.73 % and 14.31 %, respectively. Each scenario included three arrangements of factors and levels that corresponded to the L9 orthogonal array. Subsequently, a total of nine experiments were conducted, with an extensive variation in the formed grooves observed. The obtained results have shown that the groove’s deepness and grooves’ width vary substantially when the laser step settings through the developed quantitative range. The subsequent achievement in optimal response elaboration has the following ratio: 100 W laser power, 100 mm/s scan speed, and 20 kHz is a frequency. Moreover, the described ration corresponds to values derived through regression analysis. For that reason, the performed research provides a valuable contribution to furthering knowledge in laser-material interaction during the texturing procedure.
