Rapid prototyping is the simplest alternative to conventional manufacturing methods.

It doesn’t only allow fast production but also high precision of the end model.

Therefore, a lot of companies, from a variety of sectors rely on these services for creating parts and models before finalizing further mass production.

Rapid Prototyping services allow the assessment of the models’ performance in real-time. Hence, it has huge importance among manufacturing companies.

How is Rapid Prototyping Services Carried?

what is Rapid Prototyping

It is majorly a four-step process. Here is how a usual Rapid prototyping service accomplishes its projects.

Designing of 3D File

The process starts with the creation of a 3D file.

These files are the replica of the models we wish to create. In order to design these files, one must take a few important aspects into consideration.

For instance, if the model is suspected to have major tolerances, it is wise to have a 2D plan for the design ready along with the project specifications.

Using the important details into consideration, the designer creates the 3D file for the desired model.

Budgeting

Well, every process has a cost connected to it. And, rapid prototyping of models isn’t different.

The cost of the models differs depending on the myriads of factors: model finishing, geometry, and more.

Production

In the case of complex parts, companies often go with the testing of models. Experts produce only a few parts.

If the testing phase goes well, mass production happens.

Testing

To check the part’s resemblance and performance against the set requirements, the testing phase comes into play.

This decides if the 3D file will need further changes or it is okay to allow the mass production of the tested 3D file.

So, you now know that rapid prototyping has something to do with manufacturing.

And manufacturing has all things to do with products that you see all around you.

So, think about the laptop that you are using to access this article, or maybe about the cell phone or desktop or a tablet, how was it manufactured?

Think a little bit about the process of manufacturing and the calculation it requires.

The list of calculative questions starts from, what all material do you need for making the device? How much material do you need for manufacturing the device? Where will you get that raw material from?

To the end questions, how much satisfied you are with the product when compared to the idea that you had in your mind?

What has led to the little bit of dissatisfaction that you have? Is it the fault in the idea or the manufacturing process?

Rapid prototyping services is that experiment of humans wherein taking the help of a machine to manufacture a sample of the actual product and see before starting its manufacturing, go right.

So, then the question comes about how is it different from the traditional methods?

The answer to this question lies in three-dimensional computer-aided design data.

When products were developed traditionally, they were developed in one step-process from designing to creating, because it took a lot of time.

What rapid prototyping does is, gives you more scope for experimenting with your product design by developing a sample i.e. a prototype of the same before developing a product.

You can analyze this sample or prototype and see if you need any improvements in it, talk with your design team, do some edits in it, again experiment, and ensure you get the quality that you needed.

So, this gives you the foreknowledge of the product before its creation.

Introduction

A group of techniques that are used to quickly create a scale model of a part or assembly using three-dimensional computer-aided design data is called rapid prototyping.

Going back in history, we find out that the first rapid prototyping technique was Stereolithography. It was developed by 3D Systems of Valencia, CA, USA.

The company was founded in the year 1986. Since that year rapid prototyping techniques have grown from one to many.

References have also been made to solid free-form manufacturing as rapid Prototyping.

Other references include computer automated manufacturing and layered manufacturing.

One of the most basic uses for rapid prototyping is as a vehicle for visualization.

Additionally, rapid prototyping models can be used for testing, an example of this is when an airfoil shape is put into a wind tunnel.

These models can be used for creating male models for tooling, for example, silicone rubber molds and investment casts.

The main benefit of this technique is that, if you are completely satisfied with the final prototype, you can consider that as a final part also.

The only downside to it is, in most cases the rapid prototyping material is not strong or accurate enough.

However, it is in your hand to choose the material that you wish to.

There is a whole range of experimental rapid prototyping methodologies that are either in development or currently used by small groups of individuals.

A list of commercially available rapid prototyping techniques is Stereolithography (SLA), Selective Laser Sintering (SLS), Laminated Object Manufacturing (LOM), Fused Deposition Modeling (FDM), Solid Ground Curing (SGC), and Ink Jet printing techniques.

Companies that offer you any of those rapid prototyping techniques are called rapid prototyping service providers.

List of rapid prototyping service providers

As soon as you try to google this term out, you get lots of suggestions.

Starting from the service providers near your location to the service providers which are far but renowned according to the search engine’s algorithm.

So, what happens exactly after going through all of these. You get to know the name of a few companies that have made it to page one or two of the search list and you decide from that, the service provider which suits you the most.

What about the service providers which are mentioned on say the fifth page of Google, would be able to reach out to them, know which services they provide, or anything?

The answer tends to be more towards no than yes.
