Mass production of toys - High precision, faster, and more economical
The high-precision and intelligent upgrading of the core components of 3D printers has provided solid technical support for the industrial upgrading of toy manufacturing. The large-scale application of 4K/8K DLP optical engines in the 3D printing field has achieved a leap forward in larger molding format and finer surface details, increasing the traditional toy manufacturing capacity by several times. The technical features of multi-machine cluster management, large-format molding, high-speed and efficient production, and full-process intelligentization have completely restructured the toy production and manufacturing mode, greatly simplified the production process, comprehensively replaced the mandatory pre-processes such as tooling and hand-carved prototyping in traditional toy development, and provided core hardware support for the flexible mass production of the toy industry.
Production Process and Industrial Development Background
Since the 1980s, the global toy industry structure has undergone in-depth adjustment. European and American markets have firmly controlled high value-added links such as creative design, IP incubation and brand output. The toy processing and manufacturing industry began to migrate to Asia on a large scale, first landing in Thailand, Hong Kong, China and other regions, and then gradually transferred to Chinese mainland. Thus, China's modern toy manufacturing industry has embarked on a process of vigorous development.
At present, China is not only the world's largest toy manufacturer and exporter, but also the world's second largest toy consumer market. Data shows that in 2024, the total retail sales of toys (excluding trendy toys) in China's domestic market reached 97.85 billion yuan, a year-on-year increase of 7.9%; after including the statistics of trendy and collectible toys, the total retail sales of the whole category reached 144.42 billion yuan. China's toy exports have long accounted for more than 70% of the global toy trade volume, making it the core hub of the global toy supply chain.
The traditional toy manufacturing process is complex and lengthy, and is severely limited by the molding process. It not only restricts the product structure design, but also has an extremely long production and delivery cycle. For standardized mass production, it is necessary to first make a hand-carved prototype, then manufacture steel tooling after verification and conduct repeated mold testing and adjustment, and then complete production through multiple processes such as injection molding, trimming, assembly and painting, with the whole development cycle of up to 3-6 months. For niche customized or limited-edition products, the unit production cost after the allocation of tooling costs is extremely high, which is not commercially feasible at all.
In the prototype development link of the toy manufacturing industry, the hand-carved method has been used for a long time to make the master mold, which is labor-intensive and time-consuming, and skilled prototype sculptors are scarce resources in the industry. With the continuous application of new technologies, some processes of toy production have gradually shifted from manual operation to automated processing, and the production efficiency has been significantly improved. The large-scale application of 3D design software and 3D printing technology has completely changed the underlying logic of toy design and manufacturing. 3D design software can realize creative ideas and complete the creation of complex structures more quickly, and to quickly transform these unrestricted designs into physical products, it is precisely necessary to give full play to the core advantages of 3D printing technology.
1. Application Status of 3D Printing Technology in the Toy Manufacturing Industry
Advanced manufacturing technology ushered in rapid development at the end of the 20th century, and 3D printing technology (also known as Additive Manufacturing, AM) was gradually formed and achieved considerable development under this industrial background. The popularization of 3D printing technology has greatly shortened the cycle of product design and manufacturing, improved the first-pass yield of product development, significantly reduced R&D costs, brought fundamental changes to the global manufacturing industry, and perfectly fits the diversified and fast-iterating consumer demand of the toy market.
3D printing is a new additive manufacturing method. It requires first building a 3D digital model of the product, then slicing the model into multi-layer sheet structures along the Z-axis, and then curing and stacking layer by layer to form a three-dimensional physical object according to different molding principles and material characteristics. The digital model can be created by 3D design software such as ZBrush, Blender and Maya, or obtained by 3D scanning of physical objects, and can be prepared for printing after being processed into formats commonly used in 3D printing such as STL/OBJ/3MF. Based on different molding materials and curing principles, the industry has also formed a variety of 3D printing technology routes adapted to different scenarios.
In the early stage of the development of 3D printing technology, the toy manufacturing industry has started relevant application exploration, and gradually matured with the iteration of technology. Today, 3D printing has become an indispensable core manufacturing method in the new product development, prototype verification, and small-batch production of toys, and has also had a subversive impact on toy creative design. In the initial stage of application, 3D printing technology was mainly used to replace traditional hand carving and CNC machining to make hand prototypes. However, hand carving has extremely high requirements on the skills of technicians, and it often takes weeks to make a hand prototype with complex structures. Once a mistake occurs, it is difficult to repair, which is completely unable to adapt to the fast-paced development needs of the industry.
At present, 3D printing is deeply related to more than half of the toy manufacturing links. Whether it is indirectly used for prototype verification before tooling or directly used for small-batch production of finished products, it greatly simplifies the toy production process and promotes the transformation of the entire toy industry towards customization, complex structure design, and full-process digital manufacturing.
There are many 3D printing technology routes applied to toy manufacturing, among which Digital Light Processing (DLP) and Liquid Crystal Display (LCD) mask-based photopolymerization are the most mature and widely used technologies. In the industry, equipment using these technologies is generally referred to as photopolymer resin 3D printers. The core consumables adapted to toy manufacturing are mainly high-performance red wax resins, which can be divided into general-purpose and high-end special-purpose types according to application scenarios. At present, in addition to prototype development, they have gradually penetrated into the small and medium-batch finished product manufacturing links.
The core advantage of 3D printing technology is that it can quickly complete the manufacture of 3D entities and greatly simplify the conversion process from design to prototype. However, for a long time in the past, it has always been difficult to play a core role in the mass production of toys. The core reason is that the printing cost of a single product is relatively high, the mass production efficiency of a single device is insufficient, and the comprehensive cost and production cycle cannot compete with the traditional tooling and injection molding process.
2. New Digital Light Processing 3D Printing Technology Enables Mass Production of Toys
In recent years, photopolymer 3D printing technology has ushered in rapid iteration, with continuous breakthroughs in printing speed, expanding molding format, continuous optimization of the performance of red wax resin materials adapted to toy manufacturing, and steady decline in costs, creating mature conditions for the realization of flexible mass manufacturing in the toy industry. The CLIP (Continuous Liquid Interface Production) technology of Carbon in the United States and the cDLM technology of Envisiontec in Germany have greatly improved the printing speed through continuous liquid surface molding technology; domestic manufacturers have also launched mass-produced DLP/LCD equipment adapted to red wax materials for toy manufacturing scenarios, focusing on the implementation of mass printing and manufacturing in the toy industry.
2.1 Personalized Demand and Diversified Design
At present, toy consumer demand is accelerating towards personalized and diversified direction. Toys are no longer just entertainment products for children. Trendy toys, collectible figures, IP derivatives, and customized toys have become the core needs of young consumer groups. Consumers pay more and more attention to the uniqueness and scarcity of products. Traditional manufacturing processes cannot provide efficient production support for fast-iterating creative designs, and even the best designs are difficult to implement.
It is precisely because of the popularization of 3D printing technology that designers' creative tools have become more abundant and easy to use, especially the emergence of powerful 3D design software and AI modeling tools in recent years, making toy design easier and freer. Obtaining physical data through 3D scanning for secondary creation has realized the creative freedom of "everything can be designed", and these complex creative designs ultimately need to rely on 3D printing technology to complete the transformation from virtual to reality.
2.2 Hardware Upgrading Facilitates Mass Manufacturing
The high-precision and intelligent upgrading of the core components applied to 3D printers has provided technical support for the large-scale upgrading of toy manufacturing. For the first time, 4K/8K DLP optical engines have been applied to toy-specific 3D printing on a large scale, achieving a breakthrough in larger molding format and finer surface details, and increasing the manufacturing capacity of a single device by several times compared with traditional models. The technical features of multi-machine cluster management, large-format molding, high speed and high efficiency, and intelligentization have completely changed the production and manufacturing mode of toys, greatly simplified the production process, completely replaced the necessary tooling and wax injection processes in traditional development, and provided core hardware support for the mass production of toys.
Cloud-based equipment monitoring technology can realize remote control and status monitoring of multiple devices, greatly reducing the workload of on-site manual attendance; with the technical iteration of the automatic loading and unloading system, it can realize automatic assembly and disassembly of the workbench in the future, and completely complete the unmanned production closed loop. The continuous liquid surface molding 3D printer specially optimized for toy red wax materials not only greatly improves the printing speed, but also effectively eliminates the layer line problem in the stacking manufacturing process. The surface of the printed finished product is smooth and delicate, and it can enter the subsequent painting process almost without manual grinding, completely solving the pain point of high post-processing cost of traditional technology.
2.3 Material Upgrading Facilitates Process Optimization
Materials are the foundation of industrial production. Different material characteristics determine the technical route and process adaptability of 3D printing, and the performance of materials directly affects the final effect of the product. Different from conventional single 3D printing materials, the photopolymer resin system has a rich variety of categories, and can provide material solutions with different characteristics such as high toughness, high hardness, and high temperature resistance according to the different needs of toy manufacturing.
In the toy manufacturing process, silicone molding is the core process for small-batch production, and the core of this process lies in the production of high-precision and high-performance prototypes. The red wax resin specially developed for toy manufacturing, with its characteristics of high precision, high strength and high surface quality, perfectly replaces the traditional manual prototype and becomes the core material of toy manufacturing. Among them, 517H general-purpose red wax for toy LCD & DLP and 308S high-end special red wax for toy DLP are the most widely used benchmark materials in the industry at present. Both materials have ultra-high hardness and strength, and the printed finished product has a smooth and delicate surface, which can instantly transform the designer's creative inspiration into a visible and touchable physical prototype. It can not only provide reference for design modification and finalization, but also be directly used as the prototype of liquid silicone mold.
The core performance parameters of the two red wax materials are as follows:

This type of high-performance red wax material has the industry's top detail capture ability, can perfectly replicate micron-level complex details such as hair, clothing lines, hollow textures, no need to worry about the inability to print tiny features, and can easily achieve extremely challenging creative models. At the same time, the surface finish of the printed finished product is extremely high, no manual grinding is required, and only minimal finishing is needed to achieve perfect results, which greatly reduces the labor cost and time cost of post-processing.
Different from the early castable resins with large thermal expansion and easy deformation during the thermoforming process, the new red wax resin takes into account both photopolymerization formability and dimensional stability, with a molding shrinkage rate of less than 0.2%, it is not easy to deform when printing complex structures, and the dimensional accuracy can reach ±0.05mm, which is perfectly suitable for the precision assembly needs of toy figures. The technological breakthrough of red wax materials has not only greatly simplified the process flow of toy development, even completely eliminated the traditional tooling link, and directly completed small-batch finished product manufacturing through 3D printing; at the same time, it has greatly reduced the workload of subsequent manual processing. Except for simple support removal, the rest of the surface treatment processes can be completed by automated equipment, providing a solid material guarantee for the flexible mass production of the toy industry.
3. Conclusion
