Manufacturing Techniques

Laser Metal Deposition Shaping (LMDS) is a Rapid Manufacturing (RM) process that can be classified under the area of layered manufacturing techniques, where parts are built in layers. Parts of any complexity can be built directly from the 3D CAD model without much human intervention and requires minimum post-processing. In fact, LMDS technique can be recognized as multilayer laser cladding. Accordingly, it is necessary to perform the elementary laser cladding experiments with common metal powder so as to better understand the LMDS process. Then the characteristics of microstructure, composition and phase of as-deposited clads were analyzed through SEM and XRD, as well as relative model. The results prove that the microstructure of 316 stainless steel deposits is composed of the slender dendrites growing epitaxially from the substrate, and the composition is uniform without obvious segregation. Besides, it can be deduced from XRD diagram that the microstructure is composed of mono-phase γ.

Rapid Prototyping System

This paper presents a new complete CAD-driven rapid prototyping system for polystyrene. ModelAngelo, as it is called, consists of six subsystems featuring hardware and software. The system utilizes a virtual 3D CAD model to produce a set of commands used to control a 5-axis CNC Machine to move a heated-wire tool into a block of polystyrene to form the desired surface. The ultimate goal of ModelAngelo is to reach the stage of “what you see is what you get”. An overview of ModelAngelo system is first presented followed by a detailed discussion of ModelAngeloSoftware. The various mechanical subsystems responsible for realizing the final product are then described. Advantages and disadvantages of several tooltip designs are discussed and the best solution is selected. The main features of the robotic arm, which carry the tooltip is also discussed in detail. Finally ModelAngelo controller that manages the interaction between software and hardware is briefly highlighted and possible applications of ModelAngelo are suggested.

Rapid Prototyping (RP) has been considered, over the last decades, as a highly promising technology for reducing product development time and cost, as well as for addressing the need for customization and faster response to the market needs. Nowadays this technology is also used widely in medical applications (Medical Rapid Prototyping – MRP), supporting diagnosis and treatment in Neurosurgery, Orthopedic and Dental-Cranio-Maxillo-Facial surgery as well as in Tissue Engineering. The scan data that are usually obtained by Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) are used to build a 3D CAD model of the patient’s pathological region. The 3D model is used to construct the real size prototype using one of the existing RP processes. This assists surgeons in gaining a detailed insight of the problem, making the diagnosis and treatment easier and more reliable. This study presents the current benefits and barriers of Rapid Prototyping and Manufacturing methods and applications in the field of medicine. Most of the recent state-of-art developments and case studies of MRP are presented. Their limitations are discussed along with the challenges to be addressed in the future.

The prototype of a production can be manufactured directly from its 3D CAD model data by using rapid prototyping technology, and can be renewed conveniently after modifying the CAD model. In this paper, the basic principle, typical prototyping systems are introduced, and rapid prototyping methods such as selected laser sintering of powder material, fused deposition modeling of threadlike material and laminated object manufacturing are presented. An application of rapid prototyping technology on design and development of first aid kit is described in detail. It is indicated that rapid prototyping technology is an effective means to lower the cost and shorten the period of development of medical equipment.

The project and techniques of driving rapid prototyping (RP) machine within CAD system were researched to avoid the precision decreasement of the data transfer from CAD to RP system. The method of achieving the layer’s contour scanning data within CAD system was researched; then, the data transfer model of direct integration of CAD and RP was established; finally, tests were conducted on a polystyrene foam cutter machine with example of layer generation. Tests show that the approximate processing to 3D CAD model can be avoided during data transfer between CAD and RP, and RP machine can be driven and controlled within CAD system.

Tooling is one of the most important elements in the manufacturing process. To achieve the high quality requirements, moulds are traditionally made by CNC-machining, electro-discharge machining or conventional technologies. The term Rapid Prototyping (RP) refers to a group of technologies that can automatically construct physical model from Computer Aided Design data. Rapid Prototyping allows them to be made quicker and less expensively. The Rapid Prototyping techniques involves basic five step process like, Create a 3D CAD model of the required design, Convert the CAD model to STL format, Slice the STL file, Construct the model Layer by Layer and finally Clean and finish the model. Rapid Prototyping is widely used in fabrication of intricate parts of automotive, aerospace, medical and consumer products industries. Also especially moulds are made from RP model from Rapid Tooling. In this paper, a case study of manufacturing of engine head is taken. In contrast to construction of models by machining, based on the removal of material until the required form is achieved, RP model is made by adding material layer by layer until the whole part will be completed.

The article describes an attempt to address the automatized evaluation of student three-dimensional (3D) computer-aided design (CAD) models. The driving idea was conceptualized under the restraints of the COVID pandemic, driven by the problem of evaluating a large number of student 3D CAD models. The described computer solution can be implemented using any CAD computer application that supports customization. Test cases showed that the proposed solution was valid and could be used to evaluate many students’ 3D CAD models. The computer solution can also be used to help students to better understand how to create a 3D CAD model, thereby complying with the requirements of particular teachers.

In this paper, we present the first steps in the process of the modeling in ADAMS MBS of MSC software of the mechanical system of an articulated robot, with six revolute joints. The geometric 3D CAD model of the robot, identical to the real model, in the PARASOLID format, is imported into ADAMS/View and then are presented the necessary steps for building the kinematic model of the robot. We conducted this work, in order to help us in our future research, which will consist of kinematic and dynamic analysis and optimization of the robot motion.
