3D printing is a one of a new solution of manufacturing methods. This is caused by the ability of print a small part in a short time (rapid prototyping), but also because of the available materials. This is important because by using 3D printing, a specialized element is made for a specific apply. Compared with traditional production methods, such as turning and milling, 3D printing gives a wider possibility of making specific product patterns, thanks to which this method gained support and became a competitive one. Hence, the designing and manufacturing process based on it is more and more often referred as the “design-driven manufacturing”. This method gives the possibility of making personalized elements or a larger number of product variants, but also gives the possibility of manufacturing complete elements in one run. The article describes the possibilities of using 3D printing in the production of unusual elements in a uncertain situations.

A product that will be mass produced requires an initial prototype so that it can assess whether a product design meets the desired criteria and is ready to be mass produced. For the purposes of making the initial prototyping, one alternative is to use 3D printing. Prototyping is an early example of a concept as part of the product development process. Rapid Prototyping allows the visualization of a 3D (three-dimension) image into an original three-dimensional object that has a volume. In addition, rapid prototyping products can also be used to test certain parts. In the design process the 2017 Solidworks software and manufacturing process are used anet type 3D printer. In the manufacturing process many 3D Printer parameters must be regulated and very influential on the manufacturing results to be obtained, including the 3D printer parameter settings in the slicing process. This is a process that is very influential on the results, where the process of slicing the material temperature, printing speed, wall thickness, layer thickness and support must be set properly. In the future it is expected that research on 3D printing manufacturing results with the same printer parameters for the design results of some CAD software.

Tofu industry dominates by small-scale business with traditional production methods. On the other hand, demand for tofu products is quite high, and it is needed to increase tofu production. This study discusses the making of hygiene tofu maker tools able to simplify the production process. Based on the results of interviews with three tofu home industries in Cikarang, Bekasi, 17 request attributes of making an assistive tool obtain. Based on this, four technical responses were collected and will be developed become four concept designs. After conducting concept selection, it is determined to plan for making a tool which can simplify the process of making tofu. That is, starting from the manufacturing process, which starts from the pulp to the process of making tofu, can be put together into one manufacture of the tool. Thus, designing this tool can integrate the six stages of the tofu production process.

The expansion of the markets corroborated with product customization and short time to launch the product have led to new levels of competition among product development companies. To be successful in the globalization of the markets and to enable the evaluation and validation of products, companies have to develop methodologies focused on lifecycle analysis and reduction of product variation to obtain both quality and robustness of products. Keywords: Modeling, Evaluation, Validation, Design ProcessThis paper proposes a new design process methodology that unifies theoretical results of modeling stage and empirical findings obtained from the validation stage. The evaluations and validations of engineering design are very important and they have a high influence on product performances and their functionality, as well on the customer perceptions.Given that most companies maintain the confidentiality of their product development processes and that the existing literature does not provide more detailed aspects of this field, the proposed methodology will represent a technical and logistical support intended for students or engineers involved in academic as well as industrial projects.A generic methodology will be refined based on a new approach that will take into consideration the specification types (quantitative or qualitative), the design objectives and the product types: new/improved, structural/esthetic. Hence the new generic methodology will be composed of specific product validation algorithms taking into account the above considerations. At the end of this paper, the improvements provided by the proposed methodology into the design process will be shown in the context of the engineering student capstone projects at the Université de Sherbrooke.

In this work, the authors studied and compared the two main methods used in dental practice for the automated production of orthopedic structures: the widely used CAD / CAM milling method and the 3D printing technology. As an object of research, temporary crowns were used, which were made on the basis of the same digital model: a) by the method of CAD / CAM milling from polymethylmethacrylate disks; b) by 3D printing from photopolymer resin based on LCD technology. Comparison of production methods and finished designs was carried out according to the following characteristics: strength, durability, aesthetic qualities, accuracy of orthopedic designs, etc. According to the results of the study, it was concluded that 3D printing can be a good alternative to CAD / CAM milling in solving problems of temporary prosthetics.

Rapid prototyping refers to building three dimensional parts in a tool-less, layer by layer manner using the CAD geometry of the part. Additive Manufacturing (AM) is the name given to the application of rapid prototyping technologies to produce functional, end use items. Since AM is relatively new area of manufacturing processes, various processes are being developed and analyzed for their performance (mainly speed and accuracy). This paper deals with the design of a new benchmark part to analyze the flatness of parts produced on High Speed Sintering (HSS) which is a novel Additive Manufacturing process and is currently being developed at Loughborough University. The designed benchmark part comprised of various features such as cubes, holes, cylinders, spheres and cones on a flat base and the build material used for these parts was nylon 12 powder. Flatness and curvature of the base of these parts were measured using a coordinate measuring machine (CMM) and the results are discussed in relation to the operating parameters of the process.The result show changes in the flatness of part with the depth of part in the bed which is attributed to the thermal gradient within the build envelope during build.

Purpose Additive manufacturing of concrete (AMoC) is an emerging technology for constructing buildings. However, due to the nature of the concrete property and constructing buildings in layers, constraints and limitations are encountered while applying AMoC in architecture. This paper aims to analyze the constraints and limitations that may be encountered while using AMoC in architecture. Design/methodology/approach A descriptive research approach is used to conduct this study. First, basic notions of AMoC are introduced. Then, challenges of AMoC, including hardware, material property, control and design, are addressed. Finally, strategies that may be used to overcome the challenges are discussed. Findings Factors influencing the success of AMoC include hardware, material, control methods, manufacturing process and design. Considering these issues in the early design phase is crucial to achieving a successful computer-aided design (CAD)/computer-aided manufacturing (CAM) integration to bring CAD and CAM benefits into the architecture industry. Originality/value In three-dimensional (3D) printing, objects are constructed layer by layer. Printing results are thus affected by the additive method (such as toolpath) and material properties (such as tensile strength and slump). Although previous studies attempt to improve AMoC, most of them focus on the manufacturing process. However, a successful application of AMoC in architecture needs to consider the possible constraints and limitations of concrete 3D printing. So far, research on the potential challenges of applying AMoC in architecture from a building lifecycle perspective is still limited. The study results of this study could be used to improve design and construction while applying AMoC in architecture.
