Rapid prototyping is a procedure of software development in which physical objects are robotically built by means of SFF or solid freeform fabrication. In the process of rapid prototyping, a prototype or functioning model can be built rapidly, and tested for its functionality, performance and output. The latest features or ideas can be illustrated well in the prototype and early user feedback can be gathered with regards to the product. There are various advantages of rapid prototyping.

Benefits of Rapid Prototyping: Significant advantages of rapid prototyping include reduction of project cost and risk. Generally, one or more prototypes are developed in the process of software development in a series of incremental and iterative steps. Every prototype that is manufactured is based on the previous designs’ performance and it is a corrective process through which the past design defects or problems are corrected. The product is readied for production when the prototype is refined as per requirements and meets all the design goals like manufacturability, robustness and functionality.

Whether you are manufacturing small electronic appliances, automobiles, consumer goods or large-scale parts, you already know just how important inspection and quality control are towards the continued success of your organization.

3D laser scanning is not only used for inspection purposes. The ability to scan an object or surroundings and produce digital 3D models with the collected information is proving very helpful across diverse fields. Other areas in which 3D laser imaging is creating a great impact consist of reverse engineering, the film business, anthropology and industrial design.

The accuracy of 3D laser scanning to that of top CMMs, is typically less. In general non-contact methods are slightly less accurate and repeatable, but provide greater resolution and higher speed. The ability to handle the point cloud of data produced by these approaches has also grown to be much more rigorous overtime with the advances in computing processing hardware. The capability to do full part inspection using point cloud information is now considered a necessary tool within the metrology world. A robust software package ought to handle the inspection job flow from scanning to COP manipulation and CAD analysis. For reverse engineering apps it is required to gather large point cloud information and also to organize the data for the export to reverse engineering packages.

In the industrial manufacturing space, the primary application is dimensional quality control and reverse engineering. IE in the automotive and aerospace manufacturing sectors inspection for sheet metal parts, turbine blades and automotive parts are integrated into the process. In the food industry, 3D laser scanning is being utilized for volume measurement, 360 scanning of baked goods. You may wish to use 3D laser imaging to ensure the integrity of specific components involved with manufacturing. Alternatively, you might be much more worried with verifying the final products conform to one another because of the component configuration and industry compliance requirements. 3D laser imaging greatly minimizes inspection time, thereby expediting complete manufacturing time, and almost eliminates the chance for human error.

3D laser imaging minimizes the possibility of product liability suits. By thoroughly inspecting all elements of assembly with 3D laser imaging technology (and eliminating the variability of human error), you will be delivering a quality and much more stringently manufactured product. You will also have the ability to use the 3D laser imaging information collected to document for SPC, compliance and traceability.

By employing 3D laser imaging for inspection and control, your company could be improving manufacturing yield, while demonstrating a commitment to a finished product of uncompromised quality. The 3D industry continues to evolve and broaden. Potential buyers need to define the objectives and goal of inspection and work backwards towards the technology, either tactile or non contact. Be realistic about your measurement needs; match your product for the measurement technology. With the technologies growing to be increasingly well-liked and accessible, finding the right 3D laser imaging match for your requirements ought to be a relatively simple procedure.

Plastic mould, Rapid prototype, and other types of comparison, rapid prototype Shenzhen mold with five distinctive features, as follows:

Cavity and three-dimensional surface cores were:

Plastic parts of the external and internal shape of the cavity and core by direct molding, these complex three-dimensional surface machining more difficult, particularly within the molding cavity surface of the blind pass processing, if the traditional processing methods, not only require workers with high technical level, supporting more than fixtures, cutting tools, and that the processing of long period.

Long process to create a tight schedule:

Mold expert Luo Baihui that, for injection molded parts, the other parts are mostly composed of a complete package of products, and in many cases are in other parts have been completed, eagerly awaiting the injection molded parts of the package listing. Because of the product shape or size precision is high, And because of the characteristics of different resin 材料, mold manufactured, you may need repeated 地 tryout and revision, enabling developers and the delivery time very nervous.

Remote design and off-site manufacture:

Mould is not the ultimate goal, but the final products made by the user design, mold making factory according to user requirements, design and manufacture of molds and in most cases, the products of production are also other manufacturers of injection. This resulted in product design, mold design, manufacturing and product production off-site is proceeding.

Professional division of labor, the dynamic combination of:

Mold production volume is small, generally belong to a single piece of production, but the mold needs a lot of standard parts, large mold, small thimble, they can and can not be completed by only one manufacturer alone, and manufacturing process complexity, general equipment and CNC devices use very uneven.

For general mold cavity design and manufacturing cycle of constructed feature-based injection mold cavity design and manufacturing systems. The system uses interactive features of the library based on feature recognition methods to identify the characteristics of products, the establishment of product feature model. By undercut features were distinguished to determine the direction of optimization parting, and to determine the parting line and parting surface.

Mold cavity parting surface segmentation method to obtain the template. Rapid prototype Shenzhen Also made the mold cavity feature extraction algorithm to extract The characteristics of the mold cavity, the mold cavity and the manufacturing strategy formulation. The results show that the system could effectively reduce the mold cavity design and manufacturing cycle, to speed up the process of mold development.

3D prototyping techniques are a group of procedures that can quickly produce a tangible model of a product by using 3D CAD software. Another name for 3D prototyping is rapid prototyping. This process will create a solid physical structure of the product instead of a 2D layout. The prototypes can be used in different ways. For example, a visible image of the product can be use for communication and marketing purposes. As well as, a visual representation of the product can be used for testing and diagnostic purposes, tooling and rapid manufacturing.

Rapid prototyping is made up of a few basic steps. The first step is creating a design model of the product by using computer aided design data. The next step involves converting the computer aided model design into a stereolithography form. The stereolithography form is chopped to develop a cross sectional model. This will create a constructed band and the band will be placed topmost of another band. The final step is a clean and finished model.

Rapid prototyping has six 3D prototyping techniques that involve a variety prototyping apparatuses. In addition, the prototype apparatuses are stereolithography, selective laser techniques, laminated object manufacturing, fused deposition models, three dinensional inkjet printing and solid ground curing.

Stereolithography is one of the first prototyping techniques. This technique uses liquid polymer which is photosensitive and solidifies with the use of an ultraviolet light. On the other hand, stereolithography is considered to be the standard of rapid prototyping techniques. In 1988, the stereolithography machine was built by 3D systems. One of the disadvantages of early stereolithography was that the model created from this method would produce a deformed and brittle model.

The laminated object manufacturing technique was created with the Helisys machine. The process involves taking adhesive sheets and layering the sheets to create a prototype. In addition, the laminated paper is put together with a sticky substance and put on a spool. Laminated paper was one of the first substances used with this technique.

Selective laser techniques are a method that was developed by Carl Deckard. Deckard created the method as a thesis project to complete his Master’s Degree. This method uses powdered metal, nylon and elastomer to make a solid object.

Fused modeling is a technique that makes use of ejected thermoplastic filaments. The thermoplastic filaments are heated from the end. The tip moves on an x and y field range.

The ground curing technique was developed by Cubital. Ground curing is similar to the stereolithography method. The technique involves using ultraviolets light that heats and harden the polymer. Solid ground curing and stereolithography is different because of the way the material hardens. The ground curing technique makes a complete layer of the product at a time.

The techniques make it possible to create a quick prototype to meet important deadlines. Furthermore, 3D prototyping techniques are a fast way for businesses to create models to promote their brand.

Mass goods were finally able to be produced through the Industrial revolution of the late 18th century, thus creating economies of scale which changed society for ever, in a manner that no one could have predicted at the time. A new manufacturing technology has emerged which does the absolute opposite.

Additive manufacturing, or 3-dimensional printing, now makes it just as cheap to produce single items, as it is takes to produce huge quantities. This may have as great an influence around the globe, as the Industrial Revolution did.

A three dimension printer operates by taking a 3D computer file and using it to make a series of cross-sectional slices. Each slice is then printed, one on top of the other, to arrive at the 3D object.

First you have the chance to modify colour and shape where required, before you press the ‘print’ button. The 3D printer commences to build up the article gradually, one layer at a time, either through selectively solidifying a thin layer of plastic, or metal dust, or by depositing material from a nozzle, using tiny drops of glue, or a tightly focused beam.

The object that finally becomes visible could be a spare part for your car, a lampshade, or a violin.

Small articles can be formed by a machine similar to a desktop printer, in the corner of an office, a house, or a shop. Larger articles such as bike frames, aircraft parts, or panels for cars, require a larger machine and a lot more area.

A big number of technologies are available to create 3D printing, the major difference being in the manner the layers are created to build parts. Some processes use softening material, or melting, to create the layers (SLS, FDM), while others lay liquid materials that are treated with different technologies. In lamination systems, thin layers are cut to shape and joined together.

The process is currently possible only with certain materials (resin, plastics and metals) and with a preciseness of approximately a tenth of a millimeter.

The same as computing was in the late 1970s, it is currently the domain of hobbyists and workers in a few academic and industrial niches. 3D printing is spreading rapidly though, as the technology improves and costs lessen. The technology is being used in footwear, jewellrey, industrial design, engineering, aerospace, architecture, automotive, dental and medical industries and construction.

Original articles can be produced by an artist or engineer etc., then duplicated using a 3D Scanner and printed out with a 3D printer, known also as a fabricator or “fabber”, which now costs less than a laser printer did in 1985. The scope of this new technology is merely as limited as the imagination.

Rapid prototyping is the automatic construction of physical objects using additive manufacturing technology. To learn more about rapid prototyping, herunder I elaborate a 5 steps process to create a rapid prototyping model

A 3D Computer aided model (CAD) of the initial idea or concept sketch design will be created.
This 3D CAD model will be converted in a STL or IGES format.
The STL model will be sliced into thin cross-sectional layers.
The model will be constructed one later atop another.
The model will be finished and cleaned: your rapid prototype is ready!

CAD Model Creation: First, the object to be built is modeled using a Computer-Aided Design (CAD) software package. Solid modelers, such as Pro/ENGNEER, tend to represent 3-D objects more accurately than wire-frame modelers such as AutoCAD, and will therefore yield better results. The designer can use a pre-existing CAD file or may wish to create one expressly for prototyping purposes. This process is identical for all of the RP build techniques.

Conversion to STL Format: The various CAD packages use a number of different algorithms to represent solid objects. To establish consistency, the STL (stereolithography, the first RP technique) format has been adopted as the standard of the rapid prototyping industry. The second step, therefore, is to convert the CAD file into STL format. This format represents a three-dimensional surface as an assembly of planar triangles, “like the facets of a cut jewel.” 6 The file contains the coordinates of the vertices and the direction of the outward normal of each triangle. Because STL files use planar elements, they cannot represent curved surfaces exactly. Increasing the number of triangles improves the approximation, but at the cost of bigger file size. Large, complicated files require more time to pre-process and build, so the designer must balance accuracy with manageablility to produce a useful STL file. Since the .stl format is universal, this process is identical for all of the RP build techniques.

Slice the STL File: In the third step, a pre-processing program prepares the STL file to be built. Several programs are available, and most allow the user to adjust the size, location and orientation of the model. Build orientation is important for several reasons. First, properties of rapid prototypes vary from one coordinate direction to another. For example, prototypes are usually weaker and less accurate in the z (vertical) direction than in the x-y plane. In addition, part orientation partially determines the amount of time required to build the model. Placing the shortest dimension in the z direction reduces the number of layers, thereby shortening build time. The pre-processing software slices the STL model into a number of layers from 0.01 mm to 0.7 mm thick, depending on the build technique. The program may also generate an auxiliary structure to support the model during the build. Supports are useful for delicate features such as overhangs, internal cavities, and thin-walled sections. Each PR machine manufacturer supplies their own proprietary pre-processing software.

Layer by Layer Construction: The fourth step is the actual construction of the part. Using one of several techniques (described in the next section) RP machines build one layer at a time from polymers, paper, or powdered metal. Most machines are fairly autonomous, needing little human intervention.

Clean and Finish: The final step is post-processing. This involves removing the prototype from the machine and detaching any supports. Some photosensitive materials need to be fully cured before use. Prototypes may also require minor cleaning and surface treatment. Sanding, sealing, and/or painting the model will improve its appearance and durability.

When it comes to manufacturing prototypes, laser sintering is the wave of the future. The use of lasers has proven to be extremely effective in a variety of applications, from laser eye surgery to laser fingerprint scans to laser light shows. Lasers prove their effectiveness once again in the ways that they can be used to improve manufacturing technology. Through the process of DMLS, you can make prototypes of metal parts with ease. This technology is simple to use and can create accurately rendered parts made of a variety of different types of metals. Whatever the part you need, you can make it with laser technology.

Direct metal laser sintering, or DMLS, is a manufacturing process by which metal powder is sintered into layers using lasers. These layers are sintered together until they reach the desired thickness. They require the incorporation of support structures, which are also made from sintered metal. These support structures can be removed after sintering is complete. The finished prototype may require some additional work in order to be perfected, such as heat treatment, shot peening, and other processes. The result is a durable, accurate metal prototype that will help you to figure out whether or not your new design will work.

You can use DMLS to create prototypes from a variety of metals. You can make parts out of cobalt chrome, stainless steel, Inconel, Hastalloy, and titanium. Laser sintering applies powdered metal in 20-micron thick layers, and technology is continuing to move ahead on these innovations. Soon, you will be able to use this technology on even more types of metals and alloys so that you can get your prototypes made in the metals that you want for maximum durability and efficiency. Your prototypes will be so good that you might even be able to use them in production.

DMLS took a while to be developed, but, now that it exists, iss moving ahead quickly with different metals and further innovations in the field. There are sure to be more improvements to the technology of laser sintering, and if this process is any indication, the manufacturing world can look forward to even more efficient and cost-effective prototyping technologies in the future. The easier it is to make a prototype, the more time you will have to perfect your part or product or whatever it is that you want to improve. The wave of the future is continuing to forge forward.
