1. Introduction

3C product is the abbreviation of computer, communication and consumer electronic products, including mobile phone, personal computer, tablet computer, intelligent wearable device, digital camera, etc. 3C product covers a wide range of products, which have a series of commonness of large output, fast update. The manufacturing process of 3C product involves many links and the process flow is complex [1]. Therefore, many countries and regions attach great importance to 3C product manufacturing industry. 3C product manufacturing industry is a more popular one of intelligent application and promotion. In China, many 3C product manufacturing enterprises have become the national intelligent manufacturing demonstration pilot, and have constructed some new manufacturing modes that can be used for reference. However, due to the fact that the whole manufacturing of 3C products is oriented to mass production, it is difficult to meet people’s demand for personalized, low-cost and fast updating products.

3D printing, also named as additive manufacturing, is a subversive new technology, in which 3D model is discretized into two-dimensional sliced surface information, and then the three-dimensional entity is produced via superposition layer by layer. This innovative method is a kind of calculus manufacturing, which can control the shape and performance from the meso and micro level of materials to realize digital manufacturing in the whole process [2]. Due to the characteristics of 3D printing, it breaks through the limitation of subtractive manufacturing (turning, milling, grinding, etc.) and equivalent manufacturing (forging, casting, stamping, etc.). 3D printing can produce any complex and any shape products in any field with cost independent of batch size in any place [3]. This unique advantage of 3D printing has been well reflected during this year’s epidemic, and has become an important part of the supply chain of world epidemic prevention system [4].

3D printing is especially suitable for the processing of small batch products and can also boost the low-cost personalized customization of products, so it is especially suitable for the manufacturing of 3C product. At present, research of influence of 3D printing on global manufacturing is not much [5]. Compared with other research fields, the part of the research is seriously lacking. Therefore, it is necessary to strengthen research in this field. The purpose of this paper is to discuss effect of 3D printing technology on 3C product, including design and manufacturing. The structure of the paper lists following: this part mainly describes the characteristics of 3C products and 3D printing; the second part will describe impact of 3D printing on manufacturing; the third part will discuss the change of 3C product manufacturing system after integrating of 3D printing technology; and the last is summary.

2. Effect of 3D Printing Technology on Manufacturing Industry

The emergence of any technology is due to needs of the society, and the transformation of any enterprise is to adapt to changes of the market. 3D printing is a kind of principle innovation, which brings new opportunities and many possibilities for companies which are seeking to improve manufacturing efficiency. This technology provides designers with full freedom, so that the design is no longer limited to manufacturing, and fully releases the designer’s imagination [6]. Therefore, some lattice structure, integrated structure and topology optimization structure, as shown in Figure 1, have obtained innovative applications.

Figure 1. Innovation structure via additive manufacturing. (a) Lattice structure; (b) Integrated structure; (c) Topology optimization structure.

With 3D printing, the cost of small batch, even single and complex piece and personalized customized products can be maintained at a low level, as shown in Figure 2 [7]. Because of this, the manufacturing mode of low-cost products will no longer be obtained only through mass production in the future.

3D printing has been applied in many fields, from key applications such as aircraft parts and medical devices to common highly engineering products, such as running shoes. At present, more than 20% of the 3D printing market consists of parts in the aerospace and automotive industries [8]. In 2013, more than 22000 parts were manufactured in the aerospace industry via 3D printing [9]. The success and growth level of 3D printing in these industries shows that 3D printing technology is no longer the technical level of printing prototype, and the quality level of 3D printing components has met the strict industry standards. It is expected that it will completely change many niche areas and is expected to see exponential growth [10]. It is estimated that 3D printing will be more widely used in less than 10 years. However, 3D printing will not replace the existing production methods such as subtractive manufacturing and equal manufacturing. 3D printing will cooperate with various manufacturing modes and promote each other to make the manufacturing process more democratic [11]. Table 1 lists the impact of 3D printing on manufacturing industry.

In addition, 3D printing has a great impact on the whole supply chain and logistics of products, and has gradually become a valuable method to improve efficiency of the supply chain. According to some academic studies, 3D printing has great potential in reducing complexity of the supply chain [12]. One advantage of 3D printing technology is that it can print any kind of complex parts which make some components integrate into a product, so then assembly and pre-assembly may be cancelled. Further supply chain nodes and inventory complexity and operating costs are reduced. At the same time, 3D printing makes it possible to customize products individually. Therefore, 3D printing will have a significant impact on the logistics and inventory sectors. Through the participation of customers in design and manufacturing, even sales, the distance between customers and manufacturing enterprises is shortened. It makes enterprises rapidly response to market changes for reducing operating costs and increasing profits.

As a result, this technology can transform the global supply chain into a globally connected but fully localized supply chain, which allows some goods

originally produced in other countries to be locally manufactured. And mass customization products also reduce the demand for inventory and warehouse. The long-term large-scale production economy will give way to limited customization production, and the original “push supply chain” mode will transform into “pull supply chain”.

3. 3C Product Manufacturing Integrated with 3D Printing

3D printing has deeply been affecting the whole manufacturing industry, fundamentally changing the way of product manufacturing. According to a recent study, 3D printing is the technology of best suited for small volume, customer specific, and affordable products, which require a high degree of customization and a short lead time to bring them closer to the consumer group. On the other hand, 3D printing can use more kinds of materials, such as metal, plastic, nylon, etc. These characteristics coincide with manufacturing 3C products. The application of 3D printing technology will bring the following changes to 3C product manufacturing industry: 1) Simplification of production process, 2) Customized service on-line, 3) More complex design, 4) Digital platform mode.

3D printing serves 3C products via two ways: indirect manufacturing and direct manufacturing [13]. Indirect manufacturing actually follows the traditional injection molding or stamping process of 3C products, 3D printing is used to manufacture investment mold for injection or stamping. The available 3D printing processes include SLA, DLP technology based on photopolymerization process, and project based on ink-jet technology. The powder bed selective laser melting 3D printing equipment directly forming metal, FDM molding plastic products or SLA molding nylon are used to directly manufacture 3C products. Direct manufacturing, compared to indirect manufacturing, does not need mold and makes the manufacturing process further shorten. In addition, the direct manufacturing process can achieve very complex geometric structure, even the structure that cannot be realized by injection molding or stamping process. This creates conditions for 3C product design freedom to enhance again.

However, the direct manufacturing is not the manufacturing mode which widely accepted by 3C product manufacturing industry. The reason is that the surface precision and smoothness of 3C products via direct manufacturing process are difficult to compare with those of injection molding and mechanical processing. The post-processing is required after 3D printing, which virtually increases the difficulty of manufacturing. On the other hand, direct manufacturing process requires high purity and particle size of metal materials, which makes the cost of metal direct printing high.

Whether it is direct manufacturing or indirect manufacturing, compared with the traditional process, 3D printing reduces the manufacturing steps of 3C product and improves the productivity significantly. Meanwhile, 3D printing reduces the dependence on manual experience. This facilitates the production and quality management of 3C product processing enterprises.

Although the customization of 3C products is not a new service after the emergence of 3D printing technology, the born digital advantages of 3D printing technology make small batch customization production more advantageous in cost and efficiency, which can bring more convenient conditions for 3C product customization. At the same time, the digital characteristics of 3D printing make it have the “gene” of Internet, thus creating conditions for the combination of 3C product customization service and the Internet. Based on the above discussion, 3C product manufacturing industry integrated with 3D printing will form a new manufacturing mode as shown in Figure 3, which combines 3D printing with multiple manufacturing.

On the proposed 3C product service platform, three partners among consumers, designers and brands will share big data and exchange and communicate product data through the Internet. Only after the consumer has determined the design scheme can the production be carried out. Therefore, the integration of 3D printing into the manufacturing of 3C products is not only the improvement of manufacturing technology, it will affect the existing product customization and sales mode, and make consumers change from simple product buyers to “designers”.

On this platform, consumers who were originally in the downstream may put forward personalized requirements and participate design process in the upstream. Driven by the personalized needs of consumers and supported by the Internet, big data and information technology, 3C industry will develop towards the trend of “light luxury + light customization” [14].

3D printing can help 3C product manufacturing industry to realize the transformation from single variety (small variety) mass production mode to multi variety, small batch or multi variety and multi batch production mode as soon as possible. This is the foothold of 3D printing technology in 3C product, which can better reflect the technical characteristics of 3D printing and meet the market demand of 3C products and the fierce market competition.

4. Summary

cost and rapid upgrading. 3D printing technology is just in line with the characteristics of 3C product manufacturing industry. Integrating 3D printing into the manufacturing of 3C products, combining with the internet, big data and other new technologies, the proposed manufacturing system integrated with 3D printer has the following advantages:

1) It can enable consumers to participate in the design and obtain required 3C products online. In this way, the designed products can better meet the needs of consumers.

2) 3D printing enables consumers to enjoy complex and personalized 3C products with lower cost and shorter cycle time.

3) Based on the 3C product design and manufacturing platform, enterprises can use digital production and management via network and big data, making the whole process more convenient and simpler.

4) The mode can make small batch and single piece production become normal in low cost. It also makes “light luxury + light customization” to be a possibility and trend.
