3D printing technology, as a representative of additive manufacturing, is gradually changing the face of traditional manufacturing. Closed 3D printers occupy a place in the market with their unique advantages. This article will explore the working principle, advantages and disadvantages of closed 3D printers, and compare them with other types of 3D printers to evaluate whether they are better.
Working principle of 3D printer
The working principle of 3D printers is based on the “layered manufacturing” technology. It cuts the 3D digital model into layers of thin slices and then prints them based on the information of each layer. The printing materials can be plastics, metals, ceramics, etc., which are stacked layer by layer through a computer control system to form a complete object.
Characteristics of closed 3D printers
Closed 3D printers usually refer to those 3D printers whose construction cavity is enclosed during the printing process. This design helps control the printing environment, especially when printing environmentally sensitive materials (such as photosensitive resin), which can prevent interference from ultraviolet rays or oxygen during the printing process.
Advantages
Environmental control: The enclosed structure can effectively control the temperature, humidity, and light in the printing cavity, which is crucial for improving print quality and accuracy.
Material compatibility: Closed printers are suitable for working with multiple materials, especially those that require specific environments to print successfully.
Reduced interference: The enclosed environment reduces the impact of dust and particles on the printing process and improves the surface quality of the finished product.
Safety: For printing processes that use hazardous materials or produce harmful by-products, enclosed structures can provide better safety.
Disadvantages
Cost: Closed 3D printers are generally more expensive than open printers because they require more complex build cavities and environmental control mechanisms.
Maintenance: Closed structures may require more frequent maintenance and cleaning to ensure print quality.
Space limitations: Closed printers are usually larger and take up more space, making them unsuitable for environments with limited space.
Comparison with other types of 3D printers
Open 3D printer
Open 3D printers have a simple structure and low cost, making them suitable for beginners and users with limited budgets. However, they have weaker control over the environment and may not be suitable for printing sensitive materials.
Industrial-grade 3D printer
Industrial-grade 3D printers typically have higher accuracy and speed, making them suitable for large-scale production and high-precision applications. However, they are expensive and have high maintenance costs, making them unsuitable for individual users.
Desktop-level 3D printer
Desktop 3D printers are small in size, easy to use, and suitable for individuals and small-scale production. Their prices are relatively more affordable than industrial printers, but their printing speed and accuracy may not be as good as industrial printers.
Conclusion
Whether a closed 3D printer is better or not depends on the specific needs and application scenarios of the user. If the user needs to precisely control the printing environment or needs to print materials that are sensitive to the environment, then a closed 3D printer may be a better choice. However, if the user has a limited budget or needs frequent hardware upgrades and maintenance, an open 3D printer may be more suitable. Generally speaking, the choice of which type of 3D printer to use needs to be considered comprehensively based on printing needs, budget, and usage environment.
