A prototype is what tells an inventor how his/her product will work in the real world.
It is the first physical model of the inventor’s invention, on the basis of which he/she receives feedback from the prospective customers and companies.
There are three main stages through which a prototype has to undergo during the production process of model prototype.
The first one is Crude Prototype, which makes an inventor feel better for design concept, the second is the Working Prototype that enables a user to test some of his/her invention’s features, whereas the Final Prototype is the final product of the invention that can be built with any type of material.
CNC machine prototype model
Though there are many other ways to prototyping an invention idea, Rapid Prototyping (RP) and CNC machining relate to the two main categories of prototype production.
Both types of prototype modeling have their own pros and cons, there is an increased growth in the efficiency of CNC machining, as compared to Rapid Prototyping methods.
The latter leverages a CAM/CAD software-programmed machine, which helps in creating prototype design within a fraction of time.
Contrary to the Rapid Prototyping, the CNC-machining centers helps in creating prototypes using different materials, such as plastic, wood, metal and ceramics.
That apart, it helps in producing pieces of all complicated sizes and shapes.
Rapid Prototyping model
The Rapid Prototyping, aka “layered manufacturing,” offers many options to fast fabricate prototypes.
The RP machine leverages three-dimensional (3-D) CAD drawings to begin with the prototype modeling process. It cuts model into many sections.
Thereafter, a three-dimensional (3-D) laser creates one drawing of the layers on the inside of a vat of liquid plastic.
As the plastic gets harder, a platform reduces it to just a fraction of a millimeter, and the next layer is pulled out.
This process goes on working unless the process of model prototype is finished.
Rapid Prototyping also helps in creating highly complex shapes and works great when it comes to creating a logo design; but this process is not as quick as the earlier one.
A single layer, based on the nature and size of a prototype, just has a few seconds to complete.
Once it is done, the plastic gets improved before declaring it a complete product.
A few of the examples of prototyping techniques include: Stereo-lithography, elective Laser Sintering, LOM and Fused Deposition Modeling.
The increasing number of invention techniques determines the progress of prototype model as the methods are used for their productions.
Since there is constant growth and advancement in the technology, producing prototype model flawlessly has become quite quick and easy compared to previous time.
