rapid prototyping application introduction

Up to now, rapid prototyping technology has deeply affected all walks of life and has been widely used in production links in many fields. According to my research, it is particularly prominent in the following fields, medical industry, mechanical engineering, electronic products, automotive industry, aerospace, and footwear design. At present, rapid prototyping has become the standard equipment of manufacturing enterprises.

Rapid prototyping improves manufacturing

1. Promote the rapid development and design of products.

2. It can support high-precision production.

3. Improve the creativity and flexibility of product development.

Process classification of rapid prototyping

According to the different molding principles and molding materials, the rapid prototyping process currently used in the furniture design and manufacturing process can be divided into the following 4 types:

1. Fused deposition process

The Fused Deposition (FDM) process is to melt the filamentous thermoplastic material at a specific temperature. The material is always kept in a liquid state and extruded uniformly through the extrusion head. Under the control of the molding data, it is selectively deposited on the work platform and immediately cooled and solidified after deposition.

2. Stereo light curing process

The stereoscopic light curing (SLA) process utilizes the material properties of photosensitive resin. The phase change from liquid to solid. The molding data control the trajectory of the ultraviolet light beam, and selective scanning is performed on the surface of the photosensitive resin to achieve point-by-point curing and molding.

3. Three-dimensional printing process

The principle of the three-dimensional printing (3DP) process is the bonding and forming of powdered materials under the action of a binder. Spread a layer of powdered material on the working platform. Then use the nozzle to distribute the adhesive to the powder area that needs to be molded, realizing the powder's cohesive form.

4. Selective laser sintering process

The selective laser sintering (SLS) process principle is the melting and bonding of powdered materials under laser sintering. Lay a layer of powdery material close to the melting point on the working platform, and then use a laser to scan the layer of powder selectively. The temperature of the powder in the scanned area rises, and it is sintered after melting.

● Mechanical Engineering

● Electronics

● In Footwear Designing

● In automobile industry

Aerospace field

Medical Industry

The application of rapid prototyping technology in the medical field: medical device design

 trial production,

trial use

the materialization of CT scan information

surgical simulation

configuration of human bones and joints, etc. 

These technologies have been widely used in many specialties, such as cranial surgery, neurosurgery, plastic surgery, oral surgery, etc., to help surgeons in surgical planning. If there is no rapid physical model, these are impossible to do.

Compared with the two-dimensional images acquired by traditional medical imaging equipment such as CT and MRI, the 3D model produced by rapid prototyping technology can present more realistic three-dimensional data, assisting doctors in more accurate surgical planning. , Improve the success rate of surgery. The Orthopedics team of Southern Medical University has achieved a clear grasp of the location, displacement, and direction of bone damage through the printed physical model to understand the patient's condition in detail and plan the surgical plan. Especially for fractures, orthopedic repair, deformity correction, and other high-risk and complex operations, the 3D model provided by rapid prototyping technology provides essential treatment information for preoperative planning.

Mechanical Engineering

In the manufacturing industry, rapid prototyping technology is an advanced manufacturing technology that has been rapidly developed in industrialized countries such as the United States. Rapid prototyping is of great practical significance for shortening the development cycle of products, reducing development costs, and improving market competitiveness.


Rapid prototyping is very common in the electronics industry. Still, the application of rapid prototyping 3D printing technology in the electronics industry does not just stop at the "surface" of electronic products. More exciting applications are the printing of PCBs (printed circuit boards) and in many applications. The components are printed directly on the substrate.

In Footwear Designing

Rapid prototyping 3D technology gives shoe designers unlimited design space. With additive manufacturing, the potential of shoe design is unlimited. Being able to design and print out functional and ever-changing prototypes within a few hours will take several months if it is traditional manufacturing.

in automobile industry

Rapid prototyping 3D printing technology is almost the earliest application in the field of automobile manufacturing. Today's automobile appearance is becoming more and more gorgeous, closely related to the cost-saving and unlimited creation of rapid prototyping. Rapid prototyping technology can produce almost all auto parts prototypes from car interior parts, tires, engine blocks, air ducts, etc.

aerospace field

Rapid prototyping and rapid iteration,The traditional process is used to manufacture turbine blades, during which molds need to be opened. It takes about half a year from design to manufacturing. In contrast, the use of additive technology can quickly achieve iteration within one month.

Improve the degree of design freedom. In the past, components with very complex designs were challenging to manufacture, cost very high, or even impossible to manufacture.

It can reduce costs, does not require molds, and can be manufactured quickly. In addition, it is repaired. Repair is a big problem for civil aviation. To reduce costs, the use of additive methods can reduce costs by one-fifth.
