Rapid prototyping refers to building physical models from computer-aided design (CAD)data.
This type of modeling creates the original unique structure of a physical model designed in digital form.
The main purpose of rapid prototyping is to create a 3D object by using a 3D printer, resulting in a tangible prototype of the design.
To execute the object perfectly, the duration of making the object can be extended from several weeks to several months.
Compared to the old one, the process consumes less time and money.
Since the technological advances used to bring effective results, there are many sources available for the rapid prototyping process.
Prototype manufacturing includes two processes: subtraction and addition.
The subtraction process involves cutting plastic materials before the prototype is created.
Subtraction prototypes are produced using most traditional processes.
Such prototypes are generated using milling, drilling and CNC machining
Another drawback of subtraction is that they usually only do simple shapes, and it is impossible to achieve complex geometry in the subtraction method.
The addition process is a new technique for creating larger, more complex objects within a specified time frame.
The add process is done using a 3D printing
device that takes a layered approach until the part is completed.
This is a time-consuming and fast process.
3D printing is the process of converting the physical form of an object from the digital nature of the object.
This is an add-on process that is completely different from the old version of traditional prototyping methods such as cutting and grinding edges.
Usually, this process is done by laying a layer of material continuously.
Because it is a fast-growing process, it is now applied in the jewelry field, in the automotive field, in the plastic field, in the industrial design field and in the construction field.
This is mainly due to the rapid growth of advanced technology hidden behind this process.
The use of additive manufacturing obtains designs from CAD and other animation software, converts them into vertical and horizontal cross-sections, and creates structures until the shape is formed.
The same virtual and real model is the WYSIWIG process.
Production of stereo prototype method (SLA)
Is an additive manufacturing process that forces the use of UV resin or UV lasers to make layers layer by layer at a time.
It is also considered to be one of the rapid emerging processes of building solid prototypes using liquid photo polymers.
Hope the above facts are helpful for you to understand the fast prototyping and 3d printing services.
