3D printing is a new production and processing method, which is different from traditional methods. Currently, 3D printing can print soft glue, but the soft glue for 3D printing is not like the soft glue processed by traditional methods, which can change the color and softness at will. The softness, hardness, and color of the soft glue for 3D printing cannot be adjusted, and the common one is white.

3D打印軟膠主要有2種工藝，光固化和激光燒結2種，光固化的軟膠硬度只有50到60度，力學性能一般，不怎么耐磨和耐撕裂，沒什么彈性，只能用于測試軟的產品的原型打樣，激光固化的軟膠硬度有90度，耐磨和彈性好，性能比較接近傳統軟膠了

There are two main processes for 3D printing soft glue, namely light curing and laser sintering. The hardness of the light cured soft glue is only 50 to 60 degrees, and its mechanical properties are average. It is not very wear-resistant and tear resistant, and has little elasticity. It can only be used for testing prototype samples of soft products. The hardness of the laser cured soft glue is 90 degrees, with good wear resistance and elasticity, and its performance is relatively close to that of traditional soft glue

3D打印可以根據個人的需求進行定制，可以靈活地改變尺寸、形狀和設計。這使得打印出的模型可以完全符合用戶的要求。

3D printing can be customized according to individual needs, and can flexibly change size, shape, and design. This allows the printed model to fully meet the user's requirements.

精/確度高：3D打印技術可以實現很高的精/確度，能夠打印非常細節豐富的模型，可以表現出復雜的結構和造型。

High precision/accuracy: 3D printing technology can achieve high precision/accuracy, printing very detailed models, and displaying complex structures and shapes.

快速制作：相比傳統的制造方法，3D打印模型的制作速度非常快，可以在較短的時間內完成一個模型的打印。

Rapid production: Compared to traditional manufacturing methods, the production speed of 3D printed models is very fast, and it can complete the printing of a model in a relatively short time.

可視性強：使用3D打印技術可以生成透明、半透明或帶有空洞的模型，使得內部結構和細節可以清晰可見。3D打印模型

Strong visibility: Using 3D printing technology can generate transparent, semi transparent, or models with voids, making the internal structure and details clearly visible. 3D printing model

材料多樣性：3D打印可以使用多種材料，如塑料、金屬、陶瓷、紙張等，可以根據需要選擇Z適合的材料進行打印。

Material diversity: 3D printing can use multiple materials, such as plastic, metal, ceramics, paper, etc., and suitable materials can be selected for printing according to needs.

可重復性好：通過3D打印技術，可以重復制作多個相同的模型，保持一致性和質量。

Good repeatability: Through 3D printing technology, multiple identical models can be produced repeatedly, maintaining consistency and quality.

節約材料：傳統的制造方法常常需要大量的原材料，并會產生大量的副產品，而3D打印技術可以根據需要逐層構建模型，減少了材料的浪費。3D打印模型

Material saving: Traditional manufacturing methods often require a large amount of raw materials and produce a large number of by-products, while 3D printing technology can build models layer by layer according to needs, reducing material waste. 3D printing model

設計自由度高：使用3D建模軟件可以實現對模型的自由設計和修改，可以創造出各種獨特的形狀和結構。

High degree of design freedom: Using 3D modeling software can achieve free design and modification of models, creating various unique shapes and structures.

總而言之，3D打印模型具有個性化、精/確度高、快速制作、可視性強、材料多樣性、可重復性好、節約材料和設計自由度高等特點

In summary, 3D printing models have the characteristics of personalization, high precision/accuracy, fast production, strong visibility, material diversity, good repeatability, material conservation, and high design freedom
