Abstract In this paper, a framework for the rapid prototyping of lower-pair, geared-pair and cam mechanisms using a commercially available CAD package and a Fused Deposition Modeling (FDM) rapid prototyping machine is presented. A database of lower kinematic pairs (joints) is developed experimentally. Geared-pair and cam mechanisms are also developed. These mechanisms are then used in the design of the prototypes. Examples are presented in order to demonstrate the potential of this technique. Physical prototypes can be of great help in the design of mechanisms by allowing the 3D visualization of the mechanism as well as providing an experimental validation of the geometric and kinematic properties.

Low Efficiency

In the process of Fused Deposition molding (Fused Deposition Modeling, FDM), because the 3 d design is disconnected with manufacturing (or process), and prototype and precision is influenced by many factors, there are many disadvantages such as much design rework, difficult processing, low efficiency and high cost. Based on the concept of Design for Manufacturing ((Design for Manufacturing, DFM), this paper analyzes several factors that influence the forming accuracy, and puts forward the corresponding solutions to improve rapid prototyping manufacture parts strength and forming precision, combined with the actual rapid prototyping processing. It has certain reference value in the study of parameter selection and structure improvement of FDM process oriented component design.

Studies and researches in medical devices made evident the need of new systems and technologies for locomotors recovery of human body as to reduce the reintegration time in normal activities and, not the least, to improve the recovery quality, to give the possibility to perform natural movements identical to those before the suffered injury. Thus, the purpose of this paper is to obtain the 3D virtual model of a mechanism describing the hand kinematics, and a real medical prototype device to be used in locomotors recovery of the hand. In order to perform the movements, pneumatic fluidic actuators are used, considering that they are flexible, small, made especially for this project. A specialized software for assisted design is used to obtain the virtual model and for the fabrication of device component parts Rapid-Prototyping technology is applied, the Fused Deposition Modeling principle (FDM).

Biomimetic robots borrow their structure, senses and behavior from animals, such as humans or insects, and plants. Biomimetic design is design ofa machine, a robot or a system in engineeringdomain thatmimics operational and/orbehavioral model of a biological system in nature. 3D printing technology has another name as rapid prototyping technology. Currently it is being developed fastly and widely and is applied in many fields like the jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industry, education, geographic information system, civil engineering, guns. 3D printing technology is able to manufacture complicated, sophisticated details that the traditional processing method cannot manufacture. Therefore, 3D printing technology can be seen as an effective tool in biomimetic, which can accurately simulate most of the biological structure. Fused Deposition Modeling (FDM) is a technology of the typical rapid prototyping. The main content of the article is the focusing on tensile strength test of the ABS-Acrylonitrile Butadiene Styrene material after using Fused Deposition Modeling (FDM) technology, concretization after it’s printed by UP2! 3D printer. The article focuses on two basic features which are Tensile Strength and Determination of flexural properties.

Main Material

Fused deposition modeling (FDM) is one of the thirty techniques of rapid prototyping methods that produce prototypes from polymer materials (natural or with different grades). Acrylonitrile butadiene styrene (ABS) is one of the good material among all polymer materials. It is used in the layer by layer manufacturing of the prototype which is in the semi-molten plastic filament form and built up on the platform from bottom to top. In FDM, one of the critical factor is to select the built up orientation of the model since it affects the different areas of the model like main material, support material, built up time, total cost per part and most important the mechanical properties of the part. In view of this, objective of the present study was to investigate the effect of the built-up orientation on the mechanical properties and total cost of the FDM parts. Experiments were carried out on STRATASYS FDM type rapid prototyping machine coupled with CATALYST software and ABS as main material. Tensile and Impact specimens were prepared as per the ASTM standard with different built-up orientation and in three geometrical axes. It can be concluded from the experimental analysis that built orientation has significant affect on the tensile, impact and total cost of the FDM parts. These conclusions will help the design engineers to decide on proper build orientation, so that FDM parts can be fabricated with good mechanical properties at minimum manufacturing cost.

Working Principle

The present paper approaches the issue of using the new technology of Rapid Prototyping [1,2] in product engineering and tries to demonstrate its economic efficiency from the point of view of costs, in comparison with other technologies [. The comparison is made between Rapid Prototyping and plastic material injection. Rapid Prototyping is used for obtaining some prototypes but it also can be successfully used for individual or small series production. The background of the work briefly presented in this paper is related to some experimental research developed by the author regarding Rapid Prototyping Technologies for certain products which are belt pulleys. After the products have been physically created using Rapid Prototyping Technologies, the author was interested in quantifying its economic efficiency. The belt pulley the present paper refers to was obtained by using the Rapid Prototyping Technology FDM (Fused Deposition Modeling [).The working principle of this technology is briefly described later in this paper. As a novelty, the present paper is aiming at determining a criterion that allows a company to choose between the two technologies mentioned above.
