Chapter 1
1.0. Introduction
Rapid prototyping is the realization of an idea into a physical object in order to provide a representative of a finished product using rapid prototyping technologies to allow for appraisal and design modifications. The First rapid prototyping machine was first made available to markets in late 1987 meaning it is a relatively recent development. Rapid prototyping began as an expensive tool for manufacturing a physical model for design engineers to use to visualize their component designs. However in recent years the technology has advance so much that it is becoming cheaper to produce a component. (1)
1.1. Aim
The aim of this report is to provide an insight to rapid prototyping technologies by discussing various methods and provide the advantages and disadvantages of rapid prototyping itself.
Chapter 2
2.0. Generic Rapid Prototyping Process
The basic steps in a rapid prototype process can be summarized into the following:
1. Construct a CAD model based on the desired design.
2. Convert the CAD model to and .STL file by slicing the model into layers.
3. Building on the rapid prototyping machine
4. Support material is removed and the model is finished and cleaned.

2.1. CAD Model Construction
A component or model is constructed on a CAD (Computer-Aided Design) program. This model will represent the desired physical rendering part to be built. This model must be built with closed surfaces which defines an enclosed volume. This means that the data must specify the inside, outside and other characteristic boundaries of the model, but this does not apply if the model itself is meant to be a solid as a valid solid model will automatically be an enclosed volume. This requirement ensures that all horizontal ...

Designing An Mvp For A Day Workshop About Prototyping Essay

- Prototyping your idea: Guess is reading week and I have classes. Sound weird, well like part of our course we have a two-day workshop about prototyping. It starts on Tuesday where we have a more theoretical class and finished on Friday where we when to Fablab to create our prototype. Tuesday was a class where we discussed some theory related to the process of prototype. The main point was how to create an MVP (Minimum valuable product), why the importance of this MVP in our process. I think it was really useful to understand you don’t need to come with the final product....   [tags: Idea, Thought, Rapid prototyping, Prototype]

Incremental Sheet Metal Forming Essay

- INCREMENTAL SHEET METAL FORMING Introduction Incremental Sheet Metal Forming (ISMF) is a technique used to shape sheet metal and is usually used for rapid prototyping. The process begins with sheet metal secured below the ISMF device’s main body. A metal rod, which can be either a ball, a rounded shape or a cube is lowered onto the sheet metal and traced over the material in the desired shape. Computer software is used to create the desired product and trail paths are mapped before the process begins....   [tags: technique for rapid prototyping]

Essay Prototyping

- Prototyping The word prototype derives from the Greek prototypon, 'primitive form', neutral of prototypos, 'original, primitive', from protos, 'first' and typos, 'impression'. The first known use of the word prototype was in France in 1552 (Prototype, n. d.). A prototype is also known as a case, exemplification, illustration, instance, example, sample, specimen, or representative of a system or a part of a system. A prototype is a small-scale, incomplete, but working sample of a desire system using rapid application development (RAD) tools....   [tags: Technology, Systems Analysis]

3D Prototyping Essay

- Introduction 3D Prototyping plays a vital role in industry. While simulations allow complex analysis nothing compares to being able to hold a model in one’s hand. This used to be possible only for major companies or required a long time delay, but the development of 3D printers has allowed for a renaissance in rapid 3D prototyping. With small form factor and the ability to print many materials, the use of these machines are on the rise. It is only a matter of time until every household has one capable of producing any part required....   [tags: Technology ]

Essay on SLS and FMD Manufacturing Processing

- The manufacture industry has been developing since the industrial revolution, however with the evolution of some advanced technologies and the widespread of specialized Computed Aided Design (CAD) software, the traditional way of manufacturing products may be about to change. According to E. Sachs two needs, which are key to industrial productivity and competitiveness, are the reduction in time to market for new products and the flexible manufacture of products in small quantities [1]. A factor that contributes to the product design process is the development of prototypes, defined as a base model that can be tested and exhibits characteristics that can only be seen only when there is a phys...   [tags: design and prototyping processes]
