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打印软胶主要有2种工艺，光固化和激光烧结2种，光固化的软胶硬度只有50到60度，力学性能一般，不怎么耐磨和耐撕裂，没什么弹性，只能用于测试软的产品的原型打样，激光固化的软胶硬度有90度，耐磨和弹性好，性能比较接近传统软胶了

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打印可以根据个人的需求进行定制，可以灵活地改变尺寸、形状和设计。这使得打印出的模型可以完全符合用户的要求。

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/确度高：3D打印技术可以实现很高的精/确度，能够打印非常细节丰富的模型，可以表现出复杂的结构和造型。

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：相比传统的制造方法，3D打印模型的制作速度非常快，可以在较短的时间内完成一个模型的打印。

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.

可视性强：使用3D打印技术可以生成透明、半透明或带有空洞的模型，使得内部结构和细节可以清晰可见。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

材料多样性：3D打印可以使用多种材料，如塑料、金属、陶瓷、纸张等，可以根据需要选择Z适合的材料进行打印。

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.

可重复性好：通过3D打印技术，可以重复制作多个相同的模型，保持一致性和质量。

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

节约材料：传统的制造方法常常需要大量的原材料，并会产生大量的副产品，而3D打印技术可以根据需要逐层构建模型，减少了材料的浪费。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

设计自由度高：使用3D建模软件可以实现对模型的自由设计和修改，可以创造出各种独特的形状和结构。

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

总而言之，3D打印模型具有个性化、精/确度高、快速制作、可视性强、材料多样性、可重复性好、节约材料和设计自由度高等特点

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
