Hi,
A friend is interested in developing a bit of automation in a small trucking company where scheduling, maintenance, driver availability and truck/haulage tracking is a bit centralized and managed automatically.
Would like to integrate with Google Earth for Geo-Fencing and triggering alarms and so on.
He would like to calculate costs and help to optimize and make the pre-sales process a bit more accurate and painless.
Mostly Microsoft VB and MS Access background, so where should he start?

In research, development and study, prototypes play a very important role. These developed prototypes help to do testing before production and help to identify the possible issues that are occurring thanks to the design faults. Earlier generating a prototype model was extremely dear process and also time taking. But with the aid of computer Numerically Controlled ( CNC ) Machining, the velocity at which a prototype is developed has increased. With Rapid Prototyping, this period of time has even decreased from few days to a couple of hours.

For this computerized appliances are used that builds a three-dimensional model of a casting from a CAD drawing.
There are different forms of desktop manufacturing available relying on the wants. One can differentiate between them by the techniques these systems employ to make the layers. Following are few of the main types of desktop manufacturing :
Stereolithography uses UV ray to solidify liquid acrylic polymer layer by layer on a moving platform and after many layers, the prototype in the preferred form is formed. This process is carried on in a VAT, a device that is filling up with photocurable liquid acrylate polymer.

Fused deposition modeling also referred as FDM, is a rapid prototype technology frequently used to convert CAD drawings into physical parts. Scott Crump. Plastic or wax is soft and liquefied in the extrusion head and extruded through a nozzle. The nozzle is created to move over a trail identified by the CAD design to supply part. This way single layer is extruded and then it is fell to extrude the following layer on top of the first till the whole prototype is built, with one layer at a time.

Selective Laser Sintering uses the theory of sintering. Sintering is a heating process that stops softening and a coherent mass is produce.
There are not many more types of three dimensional printing available, like ; Laminated Object Manufacturing, 3D Printing, Solid Base Curing, Optical Fabrication and Photochemical Machining.

Rapid prototyping has supplied designers with several benefits. Designers can look their parts and in case any mistake happens they can easily fix it. Apart from industrial use they have formed part of produce. This development process provides blank patters to be used in casting. RP has also expanded biomed science. .

I know what rapid protoyping is but have heard reference to “soft tooled” parts, and don’t know what it means! Any help appreciated. Nez

For those concerned in product development, engineering, and other form-giving applications, quick prototyping technology can offer an wonderful deliverable for various applications. Prototyping can be employed for idea generation, ergonomic testing, test fitting, functional testing and even small-batch production. There are a number of rapid prototyping technologies available for use including Fused Deposition Modeling ( FDM ), Stereolithography ( STL ), Selective Laser Sintering ( SLS ), and 3D Printing. Each of these technologies has benefits and disadvantages.

Fused Deposition Modeling technology is marketed commercially by Stratasys, which also holds a trademark on the term. Like most other RP processes FDM works on an “additive” principle by laying down material in layers. A plastic filament or metal wire is unwound from a coil and supplies material to an extrusion nozzle which can turn on and off the flow. The nozzle is heated to melt the material and can be moved in both horizontal and vertical directions by a numerically controlled mechanism, at once controlled by a computer-aided design software package. In an identical demeanour to stereolithography, the model is built up from layers as the material toughens straight after extrusion from the nozzle. Stereolithography is an additive fabrication process employing a vat of liquid UV-curable photopolymer “resin” and a UV laser to build parts a layer at a time.

On each layer, the laser beam traces a part cross-section pattern on the surface of the liquid resin. Exposure to the UV laser light cures, or, solidifies the pattern traced on the resin and adheres it to the layer below. Selective laser sintering is an additive quick producing strategy that uses a high power laser to fuse little particles of plastic, metal, ceramic, or glass powders into a mass representing a desired 3D object. The laser selectively fuses powdered material by scanning cross-sections generated from a 3D digital description of the part on the surface of a powder bed. After each cross-section is scanned, the powder bed is lowered by one layer thickness, a new layer of material is applied on top, and the process is repeated until the part is completed. 3D printing is a unique form of prototype creation that has roots in standard fast printing technology. A 3 dimensional object is created by layering and connecting successive cross sections of material.

3D printers are often quicker, cheaper and simpler to use than other additive fabrication technologies. While prototyping dominates current uses, 3D printing offers amazing potential for retail consumer uses, particularly because the price of production is less than other techniques, and the part build time is low. In the most recent incarnations, 3D color printing is available. This indicates that a part can be made public to represent the colours of the completed product, to show label ideas or needs, or to indicate the results of stress research or other failure mode effects ( FME ) research. For the most part, all rapid prototype systems require a 3D computer model to start the process. Usually a big amount of file preparation must be undertaken to get a file to generate a correct rapid prototype model.

As an element of the innovation process, some corporations may employ one or several quick prototyping technologies in-house. However, being a new “cutting-edge” technology, many firms can make use of service offices to provide their quick prototyping as the requirement becomes evident. Most service bureaus have detailed internet sites to market and serve their customers. A handful of service firms are fairly enormous corporations with numerous workers and locations. Many provide related services and technologies, such as tooling, commercial design, molding and production.

However, service firms are usually tiny corporations, and while they may be little, a lot of them are vertically integrated and can supply services from idea models to finished functional parts. Service firms tend to concentrate on a number of areas such injection molding, casting, for example. Examine a company’s portfolio or case histories on their webpages, or discuss previous projects with the company to try to better understand areas of certain experience. Sculptors have also made use of the technology to supply complex shapes for fine humanities exhibitions. In the future, quick prototype technology will become more widespread and pervade even to the home.

For now, for timely and expert delivery, the use of a service bureau is the best way for most leading edge corporations, people and organizations.

Hello and thanks in advance for reading this!!
How can I get my new website listed for search engines easily? I would like it to show up in the top somewhere. My website is www.giesinc.com and I designed it with my keywords as follows in an area where they told me to put them on using SiteBuilder: (rapid,prototype,fdm,prototyping,prototy… model, abs, dimension, sst, printer, metro, detroit, area, shipping, overnight,sameday,design,services,CAD,mo… I offer nationwide delivery of solid model prototypes with same-day local service (Metropolitan Detroit Area), and overnight delivery nationwide. Prototypes are made from 3D CAD models and printed on a special printer that prints the model in 3D using ABS plastic.
Does it cost me anything to have the site listed and to keep it higher in rankings? Tx so much for your help!
