This research utilizes a 2D printer mechanism from a commercial available inkjet printer, combines with hardware and software to build up a new concept 3D printer. This 3D printer can receive printing information from personal computer, and setting the required layer thickness to stack those layers into a solid model. The largest build volume is 300x420x350 mm, print head resolution is as high as 1200x2400 dpi, and the life of printer head is longer than 12 weeks which is far longer than 4 weeks of Z Corp’s. There are many specifications are better than or equivalent to those of Z Corp’s Z-510 which is the state-of-art machine of this powder based rapid prototyping.

The Pelton turbines convert hydraulic energy into mechanical energy, through the Pelton runner, by using high heads and small discharges. The runner has a complex geometry, described in drawings by transversal and longitudinal sections that form continuous surfaces. The SolidWorks software was used to design two Pelton runners: the R1 runner with 21 buckets and the R2 runner with 19 buckets. The runners were made of polymeric materials through the Rapid Prototyping process, using the Objet Desktop 3D printer, which is based on the Objet PolyJet technology, with a layer thickness of 28 microns [1]. The runners were used to measure the hydrodynamic characteristics of a Pelton microturbine on a test rig. The paper aims to highlight the advantages of the Rapid Prototyping process compared to the traditional technology used to manufacture Pelton runners that are intended for experimental research.

Measurement Results

Rapid prototyping is closely related to 3D printers (additive manufacturing). Rapid prototyping is a technique for making a prototype model from a CAD file which is the final result, while a 3D printer is one of the processes. The 3D printer process is by melting the filament layer by layer to form a component or product. The 3D printer melting process uses a heater on the nozzle. This study aims to analyze the effect of nozzle diameter and layer thickness on the accuracy (dimensional measurement) of 3D printer objects. To determine the precision, a test object was made based on ASTM D995-08. The variation of nozzle diameter used is 0.2 mm and 0.5 mm, while the variation in layer thickness is 0.1 mm and 0.3 mm. In this study, delta type 3D printing was used with polylactic acid (PLA) material to make test objects. Dimension measurement using ASTM D5947-06. Analysis of the measurement results used ANOVA with a 2-level factorial design type and a 2 factorial interaction (2FI) model design using Design-Expert®. software. From the actual measurement results, the most accurate (precise) results are obtained on the test object with a variation of the nozzle parameters with a diameter of 0.2 mm and a layer thickness of 0.1 mm. From the analysis of the specimen measurement data, it can be concluded that the nozzle diameter significantly affects the response of length, width and height while the thickness of the layer affects the response of the length and width of the specimen.

The use of rapid prototyping technologies in the manufacturing ceramic materials has been developed in recent years due to its many advantages. Studies combining rapid prototyping using biomaterials as raw material increased significantly in recent years. The inkjet printing involves using ceramic powder with binder and a fluid released onto the sample through a printhead. The effect of dispersant in conventional manufacturing of alumina-based materials was widely known. However, there are few studies dealing on this issue for rapid prototyping. This work aims to obtain pieces of alumina via a 3D printer, inkjet model, varying concentrations of dispersant and fluid in order to compare its influence. The specimens were evaluated for their apparent porosity, density and dimensions. It was concluded that 1.0% of dispersant combined with a larger amount of solvent resulted in parts with suitable dimensions and higher mechanical strength.

This paper presents an analytical model of the tool path for staircase traversal of convex polygonal surfaces, and an algorithm—referred to as OPTPATH—developed based on the model to find the sweep angle that gives a near optimal tool path length. The OPTPATH algorithm can be used for staircase traversal with or without (i) overlaps between successive sweep passes, and (ii) rapid traversal along edge passes. This flexibility of OPTPATH renders it applicable not only to conventional operations such as face and pocket milling, but also to other processes such as robotic deburring, rapid prototyping, and robotic spray painting. The effective tool path lengths provided by OPTPATH are compared with those given by the following two algorithms: (i) a common industrial heuristic—referred to as the IH algorithm—and (ii) an algorithm proposed by Prabhu et al. (Prabhu, P. V., Gramopadhye, A. K., and Wang, H. P., 1990, Int. J. Prod. Res., 28, No. 1, pp. 101–130) referred to as PGW algorithm. This comparison is conducted using 100 randomly generated convex polygons of different shapes and a set of seven different tool diameters. It is found that OPTPATH performs better than both the IH as well as PGW algorithms. The superiority of OPTPATH over the two algorithms becomes more pronounced for large tool diameters.

The In-Mold Roller is a revolutionary printing process by which objects are 3D decorated. Products decorated by In-Mold Roller are waterproof and protected from fading. What’s more, these kinds of decorations strongly increase the beauty, desirability and value of the objects. The In-Mold Roller is now using either of gravure printing and screen printing to print PET film. However, there are some problems with these two techniques. This research is to investigate potential usages of combining In-Mold Roller with digital UV inkjet printing in 3D decoration, e.g. in personalized printing services. Study results found that when the coverage and the resolution of inkjet printing become higher, the SIDs will become higher as well. When transferred to ABS, SIDs in each combination will increase. Each combination of inkjet conditions, with the isolation of white ink, color differences are less variant. TVIs of white ink decrease 30% to 40% halftone and display in “M” type. In print contrast, C and K colors of each combination are better than M and Y colors. After transferred into print contrast, each combination of PC will be higher about 2 to5. When transferred to ABS, color variances of each combination are not huge, and color differences are about 3to5.

This paper describes an efficient algorithm for classification in large data set. While many algorithms exist for classification, they are not suitable for larger contents and different data sets. For working with large data sets various ELM algorithms are available in literature. However the existing algorithms using fixed activation function and it may lead deficiency in working with large data. In this paper, we proposed novel ELM comply with sigmoid activation function. The experimental evaluations demonstrate the our ELM-S algorithm is performing better than ELM,SVM and other state of art algorithms on large data sets.

The Cost

Educational technologists are often asked to provide assistance in the identification or creation of assistive technologies for students. Individuals with visual impairments attending graduate schools are expected to be able to work with data sets, including reading, interpreting, and sharing findings with others in their field, but due to their impairments may not be able to work with standard displays. The cost and time involved in preparing adapted graphs based on student research data for individuals with visual impairments can be prohibitive. This chapter introduces a method for the rapid prototyping of tactile graphs for students to use in data analysis through the use of spreadsheets, internet-based conversion tools, and a 3D printer.
