Defining Print Parameters

Use the Print Setup command from the Print menu to define the printer and the print parameters like paper size and print quality (see Fig. 6.7). Clicking on the Properties button opens another dialog box. The settings shown will depend on the model of your printer. 

MCBase offers the possibility to load the original CAMPUS data of different suppliers from version 3.0 and higher into one database, which allows direct comparison. It has been developed in close cooperation with the CAMPUS consortium. For more information see http //www.m-base.de/. MCBase is user friendly and offers extremely efficient handling of material data. All CAMPUS options are available define search profiles define and sort tables print tables and data sheets curve overlay scatter plots. In addition MCBase 4.1 offers search in curves search for comparable grades text search update via Internet calculation of simulation parameters. A French version of MCBase is available from the distribution agent in France. 

A number of printer-defined parameters must be considered in setting up a print run (Figure 4.29). They are briefly described in the following discussion. 

In the box Layout Elements to be plotted choose Parameters and Title. Click on the Edit Title... button in the right side button panel to enter a title. Clicking on the appropriate buttons, define the acquisition, processing and plotting parameters that you require to be printed with your spectrum. 

To start the printout operation the Print... option in the Output pull-down menu is used. If there is more than one window on the screen choosing the Print... option - and using the mouse - allows you to specify the window which should be plotted. If all windows should be plotted, use the Print all option. With Printer Setup... a variety of output device specific parameters defining the resolution, the paper size and other printer variables, may be set. 

The first step in the evaluation process is to define and document the current system use and user requirement specifications. If the system will be changed in the foreseeable future, any resulting changes in the intended use of the system should be described as well. The definition should include a list of system functions, operational parameters and performance limits. For chromatography software required functions may include instrument control, data acquisition, peak integration through quantitation, file storage and retrieval and print-out of methods and data. If the system also includes spectrophotometric detectors, the functions for spectral evaluation should be specified as well. Table 2 lists items that should be included in the system documentation. 

One can expect (see fine print further) that the greater diffusivity of the counter-ion layer as compared to that established in Helmholtz model, would only affect the velocity distribution profile of the displacement of individual fluid layers in the direct vicinity of the solid surface. The experimentally observed velocity of the mutual motion of the phases with respect to each other, v0, determined, as in Helmholtz model, by the potential change significantly (curve 2 approaches the same limiting value as curve 7 ). This is also confirmed by the fact that the distance between the capacitor plates, 8, which is the only parameter defining the geometry of the system in the Helmholtz model, is not present in the final expression.4 The thickness of the ionic atmosphere, k 1, may be used as the parameter closest to the distance 8, i.e. 8=1/k. 

A number of reports show how each parameter in the FDM process contributes to the quality (less distortion) and functionality of printed parts. The complexity of the 3D printing process arises from the number of variables which are used to define the operation of the 3D printer machine and the material. Bearing in mind the possibility of producing solid or shell objects, the correct selection of the manufacturing parameters contributes to the improvement of the properties, such as density, porosity, layer thickness, and material properties (ViUalpando et al. 2014). The intrinsic layer parameters such as printing and feed roller speeds and, extrusion temperature should not be ignored in any optimisation process (Fig. 7.3). 

It is generally understood that thinner layers lead to smoother surfaces and more dimensionally accurate parts. The thickness of each layer is defined in the third step (slicing) of 3D printing process when the construction paths are established. Therefore, the slice thickness determines the Z-axis displacement relative to the subsequent layer during production. The definition of this parameter is considered one of the most important parameters that determines surface quality (Fig. 7.4).
