Guide Of Rapid Prototyping

Usually, prototypes are required for products that have just been developed or designed. Prototyping is the first step to verify the feasibility of a product. It is the most direct and effective way to find out the defects, deficiencies, and shortcomings of the designed product, so as to make targeted improvements to the defects and provide sufficient basis for product finalization and mass production.

1.What is rapid prototyping?

Prototype refers to the verification sample manufactured in small quantities before the product is finalized. It can also be called: verification parts, equal-scale models, etc.
For products that require mold production, prototypes are one or more functional models made first based on product appearance drawings or structural drawings without opening the mold to check the rationality of the appearance or structure.

2.Types of prototypes

2.1 According to the production method, depending on the equipment used, it can be divided into 3D laser rapid prototyping prototypes and rapid CNC machining prototypes.

SLA prototypes: mainly prototypes produced by laser rapid prototyping technology.
CNC prototype: mainly produced by machining center.

2.2 According to the materials used in the production, the prototypes can be divided into plastic prototypes, silicone prototypes, and metal prototypes.

2.3 According to the desired effect, it can be divided into appearance prototype, structure prototype, and function prototype:

Appearance prototype: Mainly inspect the appearance design of the product, requiring exquisite appearance, accurate color, and low requirements for internal processing.
Structural prototype: Mainly check the structural rationality of the product, with high requirements for size and relatively low requirements for appearance.
Functional prototype: It is required to achieve the same appearance, structure and function as the real product. It can be understood as a finished product that is not on the market. It is the most demanding and difficult type of prototype.

3.Comparison of 3D printing prototype and CNC prototype

The advantages of 3D printing prototypes are mainly reflected in its speed, but it is mainly formed by stacking technology, so 3D printing prototypes are generally relatively rough.
The advantage of CNC prototype is that it can accurately reflect the information expressed in the drawings, and the surface quality of CNC prototype is high, especially after the surface spraying and silk printing are completed, it is even more glamorous than the product produced after the mold is opened.

Therefore, CNC prototype manufacturing has always been the mainstream of prototype manufacturing.

4.Materials used for rapid prototyping

Petal prototyping: ABS,POM, PMMA (acrylic), PC, PP, PA, BT, PVC, rubber sheet, bakelite, plastic king, etc.
Metal prototyping: Aluminum, stainless steel, iron, copper and other alloys

5.What are the advantages of a prototype?

Inspect the appearance design.
The prototype is not only visible but also touchable. It can intuitively reflect the designer’s creativity in physical form, avoiding the disadvantage of “drawing it looks good but making it unsightly”. Therefore, prototype production is indispensable in the process of new product development and product shape scrutiny.
Inspection structure design.
Because the prototype is assemblable, it can intuitively reflect the reasonableness of the structure and the ease of installation. It is convenient to find and solve problems early.
Avoid the risk of opening the mold directly.
Because the cost of mold manufacturing is generally very high, relatively large molds are worth hundreds of thousands or even millions. If unreasonable structure or other problems are found in the process of opening the mold, the loss can be imagined. Prototype production can avoid this loss and reduce the risk of mold opening.
Make the product go to the market ahead of schedule.
Due to the advanced nature of prototype production, you can use the prototype for product promotion before the mold is developed, and even pre-sales and production preparations to occupy the market as soon as possible.
