Rapid prototyping applications have exploded in the 21st century. This impressive technology also known as 3D printing applications has taken product creation to a new level.  It is now possible to create a prototype and the ability to create the design in a timely fashion. Models are created using rapid prototyping applications with the use of inkjet technology. This technology is powerful because of the ability to create something new from scratch. 3D printing is a type of additive manufacturing technology which is the process of fusing materials to make things from 3D model data, typically layer upon layer, contrasting from subtractive manufacturing methodologies. Rapid prototyping applications until recently were too expensive for most businesses. Nowadays, it’s becoming less expensive, more accessible and easier to use than ever before.

Reasons to Choose Rapid Prototyping Applications

Rapid prototyping applications provide noticeable quality and details to models.
While wax and other forms can be used to create models, they aren’t reliable at pinpointing mistakes in prototypes.
Using 3D printing, the sections of your model should align themselves together. If they don’t fit together, you’ve made a mistake that would have cost a lot of money if you were using wax or handmade models to fix.
Rapid prototyping applications enable you to get the job done in a timely manner and your design can get immediate feedback.  Instead of taking a few weeks or month to finish a model, 3D printing can save your company a lot of time and money.
Outsourced models will cost much than using in-house made 3D models created by 3D printing.
3D printing is also easy to use and quicker than many regular printers. You don’t need to be a rocket scientist to use 3D printing and no specialized training is necessary to get started with 3D printing.
All you need is a computer and software to use rapid prototyping applications.  3D printing allows you to make models faster and with more details.

How Do Rapid Prototyping Applications Work?

Rapid prototyping applications or 3D printing applications create a solid physical structure of a product instead of a 2D layout. The prototypes can be used in different ways. The machine is fed an image by special graphics applications and the printer will show the image. In addition, the printer will use a fine powder such as cornstarch, plaster or resin to create a 3D model that built layer by layer through cross-sections. Stereolithography is one of the most common rapid prototyping methods. It makes use of a computer controlled UV laser to solidify a photo curable liquid resin to create 3D models from CAD designs.

When surgery that involves delicate and precise technique is called for, many orthopaedic surgeons have found the use of three-dimensional models to be of extreme help. With these devices, surgeons can get a well-rounded view of the patient’s injury for planning and preparing surgical procedures. Before this important medical device was created, surgeons relied solely on CT scans and MRI’s. With the new 3-D model being used as a diagnostic tool, they can provide valuable information in diagnosing certain injuries and diseases, since they give the surgeon an up-close and in-depth realistic view of the area of concern.

Three-dimensional models are created by medical stereolithographers who are experts in this field. With the use of a MRI scan or CT scan, the stereolithographer can duplicate a 3-D model that is exactly like the anatomy of the patient. The accuracy of the model is within 1/35th of a millimeter. This allows the surgeon to hold the model and inspect the area of concern closely, which otherwise can only be evaluated with imaging results. These 3-D models can be made for any skeletal part including the skull and spine.

Not only does this new and innovative medical tool allow the spinal surgeon to analysis and diagnosis orthopedic conditions, it also is valuable in the practicing and review of exactly what the orthopaedic surgery will involve. Doctors can do a dry run of the procedure before the actual surgery, which can reduce the margin of error extremely and reduce the amount of time the surgery would normally take. This provides the patient with much lower costs of operating room and surgical team fees as well as anesthesiologist and surgeon fees. Patients are also under anesthesia for a shorter amount of time, helping to reduce the risks of complications.

With the use of 3-D models being so beneficial to patients and spinal surgeons, this incredible invention will soon be a common orthopedic tool for doctors. With these devices able to identify defects that may not be found with traditional imaging devices, doctors will be able to provide a more thorough and accurate diagnosis. They also are being used as educational tools to help patients understand exactly what the spinal injury is and how it will be surgically corrected. These models are being found to be very beneficial to patients with thoracic, lumbar and cervical spine disorders as well as individuals who suffer with lordosis, spondylosis, spondylitis, kyphosis, spina bifida and stenosis. They can also be very beneficial for patients who require back surgery such as laminectomy or repair of a spinal cord injury.

Having the ability to reconstruct items using rapid prototyping has made a difference in many ways. One example would be the Buddha of Infinite Light, Amida. This is a carved figure made of wood and lacquered. Believed to have originated in the 13th century, it is a wonderful piece of art that tells us much about the earlier cultures. However, the Buddha is believed to have originally been adorned with a necklace, topknot and crown.

The Buddha was the inspiration it took to build another one using plastic mold. Adding the missing adornments was one of the purposes for doing this. The reconstructed Buddha was made using 0.1 mm layers and was based on 3D scanning at close range. In addition, digital modeling was used and the end result was the Buddha with the accessories that were believed to be missing.

The use of selective laser sintering made the reconstruction process possible and allowed very high definition. It was constructed in one piece. The original is displayed at the World Culture Gallery in Liverpool. Other sculptors have used the technological advances made in the world of rapid prototyping to make other intricately detailed pieces for displaying in art galleries the world over.

Using computer aided design (CAD) to acquire the designs of the object for rapid prototyping, the layers are broken down. This is the model that is used to create the nearly identical physical model. By breaking down the layers, this allows the user to create the layers needed to construct the actual model. They are put together to form the shape desired. The main advantage to the process is that any shape can be made simply by using this method.

Using the methods of plastic mold models normally can be produced in a matter of hours. This does however, depend on the number of models being produced at the same time and the size of the model. The intricate detail of the model being made is another aspect that must be considered. In addition, the machine being used can affect the time it takes to make the model.

Rapid prototyping is not always rapid. As you can see, there are many factors that have an effect on the time it takes to construct a form using this method. There are many companies in the technological field that are available for rapid prototyping. The big difference is the method used to build the layers when creating the model.

The boundary that exists between the CAD software and the plastic mold machine being used is the STL file format. This is what predicts the shape of the model with the use of facets that are triangular in shape. The smallest facets generate the best quality. While some technologies use a softening or melting process to generate the layers, there are others that use liquids such as thermosets that have already been cured.

One of the types of rapid prototyping is freeform fabrication. With this method the use of two materials – one for constructing the model and one for the support – is used and the support material is later dismantled. With the use of rapid prototyping it is possible to automatically construct objects using the technology of additive manufacturing. This allows the creation of two objects – one virtual and one physical – that are typically identical. Using this fairly new technology the sky is the limit.

This technology is also used by the sculptors in order to achieve complicated shapes for display in any exhibition of fine arts. Rapid prototype creates 3D models with the help of virtual designs from animation modeling software or computer-aided design, which helps in transforming the design into thin layers, virtual and horizontal cross sections until the entire model is complete and all these can be done with the help of additive manufacturing technology present in rapid prototyping. With the use of this particular technology the virtual image can be easily transformed into the physical model.

• The additive manufacturing technology helps the machine to read data from computer aided design and builds the model with the help of layers of liquid, powder and sheet material. Various cross sections are used while building up the model. The layers are combined with the virtual cross section automatically to get the final shape.

• The biggest advantage of the rapid prototype fabrication is that it is able to form or create any type of geometric feature or shape.

• The stereo lithography helps in the plastic mould formation of the accurate shape of any object with the usage of triangular facets and aims at quality production.

• The models can be constructed within hours instead of days. The time depends on the complexity of the object to be created or the type of machine used. It definitely takes lesser time than the usual digital data or 3D.

• The technique of solid freeform fabrication uses two types of materials, the part material and the support material, which is later removed with a solvent, by water or by heat.

• There are 3D printers present in the rapid prototype machine that helps the manufacturers or the designers in the rapid development of the production.

• It helps the manufacturers by detecting the flaws and errors beforehand and thereby reduces the cost of re-work. It gives the right and clear concept of the idea and plan that is supposed to be implemented by the manufacturers.

• Rapid prototype helps in the construction of the prototype at a very low cost in a very short period of time. The plastic mold is almost similar to the actual product and it is created by the cross sections and forming layers in the free space until the model is prepared.

• It is beneficial for the implementation of new ideas and plans for the manufacturers and used in a short production cycle, where the time is very limited and the task is to be finished at a low capital investment.

For people outside the fields of engineering and technology, there can be some confusion regarding the terms “3D printers” and “rapid prototype machines.” This conundrum is to be expected since there are even engineers who are not aware that these machines exist.

Nonetheless, both these machines are used in fabricating scale models used in engineering, automation, manufacturing and mechanics. In recent years, however, the use of these machines has expanded beyond the confines of engineering to medicine, education, and even the arts. But what makes these machines different from each other?

What Are Rapid Prototype Machines?

The term “rapid prototype machine” actually refers to a wide range of machines that use many different technologies to create scale models. These technologies have names such as stereolithography, where photosensitive resin is shaped and hardened by a laser beam; solid ground curing, where the resin is cured with ultraviolet rays; or fused deposition modeling, where melted polymer is built in layers around a support structure.

Regardless of the technology used in these machines, the procedure used in creating models is almost uniform. A model is generated using CAD software, and the model is then converted into a file with an STL extension. The rapid prototype machine then processes this STL file by slicing it layer by layer. These layers are then produced on a platform using resin, and once completed the model is finished and cured.

3D Printers Are Rapid Prototype Machines

As for 3D printers, they are actually a subclass of rapid prototype machines. What makes them distinct from the other rapid prototype machines is that they are faster. The word “rapid” in rapid prototype machines can be misleading because creating models with them can still take days, even weeks. With 3D printers, you can have your model within a matter of hours, even minutes.

Most machines that are classified as 3D printers make use of inkjet printing technology, which is why they are called “printers” in the first place. This does not mean that 3D printers use inkjet technologies exclusively. There are such machines that also use derivatives of the fused deposition modeling process or the ultraviolet curing process. In 3D printers that use inkjet technology, the resin is sprayed on the printing platform using inkjet nozzles.

Another characteristic of 3D printers is that the base materials they use are usually non-toxic and do not require curing or finishing. This is a big contrast with 3D models created with stereolithography, for instance. In stereolithography, the resins that operators work with can become toxic if left uncured.

In addition, 3D printers are a lot less expensive. A starter 3D printing machine can cost US,000. While that figure cannot be considered cheap, it is relatively inexpensive compared to high-end rapid prototyping machines that can cost hundreds of thousands of dollars. There are also 3D printing machines that you can make on your own using starter kits and open source software.

Three-dimensional models are used for many different purposes and projects by movie studios, advertisers and video game manufacturers. If you would like to use a 3-D car model, there are four ways to get one. You can purchase one from a retailer in 3-D models like Dosch or Marlin 3-D, download one from the free section of a site like Renderosity, hire a 3-D modeler to make you a custom 3-D car free 3d models, or you can use a 3-D modeling program to make your own. There are several programs that you can use for this purpose, varying in price and features. But most can be used to carry out a process called box modeling.

Step by step.

Download an image of the car that you want to model. Then open Hexagon. Go to the “Scene Properties” on the right and add the car image to one of the grids as a reference.
Select the “Primitives” tab and click on the “Cube.” Draw it in the view and select the forward facing polygon.
Select the “Extrude” tool and extrude the face forward to form the front of the car. Repeat this step with the other faces to form the back and top of the car. Use the “Tessellation” tools to divide the model, giving more polygons that you can then move to refine the shape of the car free 3d models.
Add “Cylinder” primitives and use the “Boolean” function to subtract then from the model to create the tire wells. Then add more cylinders to act as the tires.
Use the “Materials/Shading Domain” function on the left to add colors to the parts. Save your work as a Wavefront OBJ.

Google SketchUp

Load the image that you want to use as a reference onto your computer. Open Google SketchUp.
Select the “Line” from the toolbar and draw the outer shape of the car on the ground. Now use the “Push/Pull” tool to raise the shape to about the height of the car door, using the image as a reference.
Use the “Line” tool to dived the shape into sections for the front, middle and back of the car. Use the “Push/Pull” tool to raise the center section to make the top of the car.
Select lines and adjust them to refine the shape of the car. Use the line tools to add more lines to refine the shape, as well as to create tire wells. Use the “Elliptical” tool with the “Push/Pull” tool to make tires.
Select the “Paint Bucket” tool and use it to fill each section with the color you want. Export the file as a Wavefront OBJ.

Wings 3D

Load the image of the car you want to make onto your computer. Open Wings 3D.
Click on the “Cube” to add one. Select the forward face. Right-click and from the options choose “Extrude.” Extrude the face to make the front of the car. Continue this process to make the rest of the car.
Use the “Inset” functions to create windows, doors and other sections. Then use the “Move” tool to select edges or points and move them to refine the shape of the car based on the reference image (free 3d models).
Save your work as a Wavefront OBJ.

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.

3D prototyping is the mechanical creation of physical substances using patented polyjet manufacturing technology. 3D prototyping technologies originated in their simplest plastic and liquid hardening versions in 1988 and were initially used to make simple static model structures. Many famous artists have used 3D prototyping technology to create installations for exhibitions. In recent years, the advancements in and the use of CAD and 3D prototyping has continued to spread. As such its important to understand the background and application for 3D prototyping processes.

Current Usage of 3D Prototyping

3D prototyping models have many uses. They make great visual aids for communicating ideas to colleagues or for presentations to customers. Being able to see, feel and hear an idea accounts for over half of one’s senses and helps make an impression on customers. One of the greatest benefits of 3D prototyping is that it can significantly reduce company costs. Outsourcing 3D modeling needs to suppliers is expensive and time consuming. With the latest 3D Prototyping equipment 3D printers can sit on a desk in your office.

3D prototyping is already applied in a number of industries and sectors. 3D prototyping is currently being used by in healthcare, engineering, education, architecture and the entertainment industry. It’s also being used by paleontologists to model fossils, duplicate prehistoric artifacts and to reconstruct bones and body parts to create a 3D tangible model of ancient mankind. Today, Architects are using 3D prototyping technology to design buildings with precise measurements and able to create 3D models in-house and therefore confidentially. Engineers are testing designs and able to locate errors and design flaws quicker and cheaper than previously.

Future Usage of 3D Prototyping

3D prototyping technology is presently being studied by biotechnology firms and universities. Their objective is to use 3D prototyping and engineering applications to create body parts and organs. Scientists can today use 3D prototyping to place layers of living cells on to gel mediums to test and learn how they react to being transplanted to humans, therefore reducing the need for live animal testing. With the help of a 3D prototype, one day recognizable pieces of furniture in a home can replaced by a 3D printer and a recycling unit. Clothing, cutlery and books can already be printed on demand.

In the future, product designers, engineers, teachers and architects will all be using 3D prototyping systems in their respective careers to teach, demonstrate and sell their concepts instantly. 3D prototyping has only been around for about 2 decades and has only recently become affordable enough for businesses to use in-house. Just imagine what the future holds for 3D prototyping printers.
