Prototyping is a process in which plan teams put ideas into substantial forms from paper to digital. To capture the design concept of different fields and test on users the design teams can build a prototype. With the help of a prototype, one might be able to clarify and confirm the design, which may help in the post of your right product of any brand.

Prototyping is an essential piece of critical design thinking and in general, people’s experience design as it permits us to test our recommendations and upgrade them according to an equitably timely fashion.

At Stanford, the institute of design can encourage a “bias towards action” where manufacturing and experimentation given importance overestimating and meeting.

Rapid prototyping is known as three-dimensional (3D) printing. It is a group of developing technologies, which produce the 3D body in layer model manner from already defined 3D computer modal.   

Rapid prototyping processes:

Rapid prototyping processes includes fine detailing of layer-by-layer deposition of the material with the help of computer design. With the help of this process, architecture engineer can hold and enhance the mechanical performance, as they desired.

 By using this process, the engineers can accelerate the renewal of bone tissues with examine bone formation from the anatomic structure of cortical-trabecular. 

For the fabrication of scaffolds, many prototyping processes include ink-jet printing, 3D modeling, laser sintering, fused deposition modeling, and stereolithography. 

Classification of prototyping processes:

In the increasing trend of the industrial importance of LM and a wide range of technologies, all are count under the rapid prototyping term. According to the premature physical conditions of the materials, the rapid processes may be classified. The initial states may include the shape as 2D or 3D, which include different elements like metals, liquid, that is freezable or curable, a reactive gas, and ceramics materials. The conversion principles include the polymerization that is either photochemical or thermally and modification such as to melt powder as well as the vapor deposition process.

Selective laser sintering:

Rapid prototyping consists of a collection of technologies that can produce a physical model from the computer-aided design. Selective laser sintering that abbreviated, as (SLS) is an additive manufacturing technique used for the production of low volume functional parts and models of the prototype.

Selective laser sintering can use the laser as its source of power to materials of sintered powered that helps in binding of the materials together to produce a solid structure.  

For example, the report of successful fabrication Duan et al. a multifunctional tissue of engineering that is biometric Nan composite, which, based on the calcium phosphate material. 

Its surface is a coat with gelatin and inactivates heparin; it provides a perfect binding site for the bone morphogenetic protein, which abbreviated as (BMP-2). It helps too, enhances the ALP activity of the body and in stem cells, it increases the osteo genesis. 

Importance of Rapid Prototyping:

The rapid prototyping changes the abstraction of the manufacturing, development of products, and derive. The past purpose of rapid prototyping is to motivate the development of the product by providing facilities to the physical models for the approval of new designs rapidly and at a cheap rate. 

It shifted to premature stages processes of product development, design security, and help to reduce the need for expensive changes that are required in later stages.

Throughout the recent years, many articles and books have published on the development, applications, and ingredients of rapid prototyping technologies. 

Rapid prototyping synonymously known as (SFF) abbreviated as solid freedom fabrication as well as layer manufacturing which abbreviated as (LM) can represent the three-dimensional (3D) layer-by-layer fabrication. It depends on pre-processing operations that help to convert the 3D models created with the help of computer design. 


The build processes pressurize by plunge factors to their operational limits. The machines of rapid prototyping are generally more effective and reliable than use for a long time. Due to the highly complex structure of the human anatomy building models, it provides a large rate of risk of failure in medical modeling than the engineering approach. The rate of risk of failure depends upon the processes, which used but mostly it depends upon the applied principle.

In rapid prototyping processes, the stability of the model is quite important. It provides the facility to position your model in the most suitable orientation like where it is more stable i.e. more in width at the bottom than the top. It will also affect the support that is required. 


Rapid prototyping technologies have major applications in the manufacturing of trade-made parts that may include the prototypes and small chain parts. Additive manufacturing considers more flexible than conventional formative modeling or casting processes. It is cheap and economically favorable for the production of models and tools when needed as the high financial and time expenditure. 

Subtractive manufacturing technologies that include computerized numerical control (CNC) machining and additive manufacturing can take benefits from a material of lower waste construction and allow federation of complex internal cuts and structure.

In rapid prototyping, the poly Jet is used to rapidly prototype and examine several wing designs for different applications. The NASA stands for National Aeronautics and Space Administration can be studied to assess the design ideas approaches for the upcoming generations and AM RP with commercial aircraft.

The preparation of a model of a wind tunnel is a critical stage, where it is used to evaluate the different operations, the structure of the proposed idea, propulsion, etc.  

Moreover, airbus also used the application of rapid prototypes to examine and evolve a new aircraft prototype. Its structure is almost 90% made up of plastic polymeric materials. It helps in savings of time. Almost in 8 weeks, rapid prototyping can permit the aircraft to manufacture.

Future Developments:

Rapid prototyping helps to generate different ways to the companies to produce new ideas and design to build new products. To improve manufacturing there are many developments. In which the first factor of development is to increase the speed. As the rapid prototype, machines are slow as by some parameters and standards. With the help of using fast speed computers, better efficiency materials, and strong complex control system and helps to reduce the rapid prototype manufacturer’s time. For example, in January 1998, the Stratasys had established the quantum machine named FDM that produce more ABS plastic models in the range of 2.5 to five times as compared to the previously present FDM machine.
