Optimization of Parameters for the Printing Process of Adhesive Application in Honeycomb Core Manufacturing

In this study, the optimization of parameters of the printing process was carried out. The aim is to minimize the size of color variation in prints. A factorial design was used to evaluate the effects and interactions of three factors, that is, impression pressure, alcohol %, and press speed. The color variation is gauged by variation in ink transfer, which is governed by color difference (?E). The optimal conditions obtained from the desirable response are impression pressure of 0.15 mm, alcohol percentage of 12.2 % and press speed of 8500 sheets per hour. Under these conditions, about 0.62 of color difference is obtained.

This work are made for determine the possibility of generating the specific parts of a threaded assembly. If aspects of CAD generating specific elements was analysed over time in several works, the technological aspects of making components by printing processes 3D through optical polymerization process is less studied. Generating the threaded appeared as a necessity for the reconditioning technology or made components of the processing machines. To determine the technological aspects of 3D printing are arranged to achieve specific factors of the technological process, but also from the specific elements of a trapezoidal thread or spiral for translate granular material in supply process are determined experimentally. In the first part analyses the constructive generation process of a spiral element. In the second part are identified the specific aspects that can generation influence on the process of realization by 3D DLP printing of the two studied elements. The third part is affected to printing and determining the dimensions of the analysed components. We will determine the specific value that can influence the process of making them in rapport with printing process. The last part is affected by the conclusions. It can be noticed that both the orientation and the precision of generating solid models have a great influence on the made parts.
