快速成型是一批用于快速建立模型的技术，是使用三维计算机辅助设计（CAD）的建筑的物理部分。山东快速成型中使用的其他技术包括：模塑、铸造、高速加工、挤压。不同类型的快速成型设计：

Rapid prototyping is a group of technologies used to quickly build models, which is the physical part of buildings using three-dimensional computer aided design (CAD). Other technologies used in rapid prototyping in Shandong include molding, casting, high-speed machining and extrusion. Different types of rapid prototyping designs:

1.立体光刻技术（SLA）

1. Stereolithography Technology (SLA)

SLA是一种快速成型制造工艺，低廉，速度快。它是有史以来种3D打印的类型。SLA使用一罐光敏液体，在与计算机控制的紫外线接触时变成固体。一旦SLA零件凝固了，它们就不能再变回液体；这个过程是不可逆的。

SLA is a rapid prototyping manufacturing process with low price and high speed. It is the first type of 3D printing in history. SLA uses a can of photosensitive liquid that turns into a solid when in contact with computer-controlled ultraviolet radiation. Once SLA parts solidify, they cannot be turned back into liquid; This process is irreversible.

2.选择性激光烧结(SLS)

2. Selective laser sintering (SLS)

SLS也是一种快速成型制造技术，适合用于塑料和金属成型制造。SLS使用高功率的激光来加热和烧结粉末层，以创建一个成型。值得注意的是，SLS产品比SLA成型要弱得多。然而，SLS要便宜得多，需要的时间和劳动力更少，同时提供高生产率。SLS零件很粗糙，在获得终零件后需要更多的精加工。

SLS is also a rapid prototyping manufacturing technology, suitable for plastic and metal molding manufacturing. SLS uses high-power lasers to heat and sinter powder layers to create a molding. It is worth noting that SLS products are much weaker than SLA molding. However, SLS is much cheaper, requires less time and labor, and provides high productivity. SLS parts are very rough and require more precision machining after obtaining the final part.

3.材料喷射或熔融沉积成型（FDM）

3. Material Spray or Melt Deposition Molding (FDM)

材料喷射也是一种快速成型制造工艺，速度快，合理，易于使用，而且便宜。FDM好用于产品开发。FDM使用在打印喷嘴筒内熔化的热塑性塑料丝来创建成型。打印机通过来回移动喷嘴而工作。通过使用计算机沉积程序，塑料被分层以形成成型。图片

Material spraying is also a rapid prototyping manufacturing process, which is fast, reasonable, easy to use and cheap. FDM is good for product development. FDM uses thermoplastic wire melted inside the printing nozzle barrel to create a molding. The printer works by moving the nozzle back and forth. By using a computer deposition program, plastic is layered to form a shape. picture

4.粉末床融合（PBF）或选择性激光熔化（SLM）

4. Powder Bed Fusion (PBF) or Selective Laser Melting (SLM)

SLM是常用的快速成型制造类型。这种方法在航空航天、汽车、国防和医疗公司很受欢迎。它是受欢迎的方法，因为它的成本较低，而且能制造高质量的零件。该方法使用高功率或电子束来熔化与粉末分层的粘合剂，以创建生产零件或成型。PBF使用基于动力的材料，如：铜、铝、不锈钢。

SLM is a common type of rapid prototyping manufacturing. This method is very popular in aerospace, automotive, defense, and medical companies. It is a popular method because of its lower cost and the ability to manufacture high-quality parts. This method uses high-power or electron beams to melt and layer the adhesive with the powder to create production parts or forming. PBF uses power based materials such as copper, aluminum, and stainless steel.

5.片材层压或层压物体制造(LOM)

5. Sheet Lamination or Laminated Object Manufacturing (LOM)

与SLS和SLM相比，板材层压没有那么复杂。这个过程不需要你在一个特别控制的环境中来达到你想要的结果。片材层压的工作成理是利用激光束将一层层的金属、塑料和陶瓷切割物放在一起，以创造出所需的CAD设计。每一层都用胶水粘合起来，直到整个部件完成。然而，这种方法是劳动密集型的，需要大量的时间。

Compared to SLS and SLM, sheet lamination is not as complex. This process does not require you to achieve the desired results in a specially controlled environment. The working principle of sheet lamination is to use a laser beam to place layers of metal, plastic, and ceramic cutting materials together to create the required CAD design. Each layer is glued together until the entire component is completed. However, this method is labor-intensive and requires a significant amount of time.

6.数字光处理(DLP)

6. Digital Light Processing (DLP)

DLP与SLA方法几乎相同。DLP使用的是树脂聚合，使用一束光进行固化。DLP的光源来自投影仪，而SLA的光源则来自激光束。DLP比SLP更便宜、更快速，但它在后期固化方面需要更多基础设施。

The DLP and SLA methods are almost identical. DLP uses resin polymerization and a beam of light for curing. The light source of DLP comes from a projector, while the light source of SLA comes from a laser beam. DLP is cheaper and faster than SLP, but it requires more infrastructure in terms of post curing.
