快速成型是一批用于快速建立模型的技術(shù)，是使用三維計算機(jī)輔助設(shè)計（CAD）的建筑的物理部分。山東快速成型中使用的其他技術(shù)包括：模塑、鑄造、高速加工、擠壓。不同類型的快速成型設(shè)計：

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.立體光刻技術(shù)（SLA）

1. Stereolithography Technology (SLA)

SLA是一種快速成型制造工藝，低廉，速度快。它是有史以來種3D打印的類型。SLA使用一罐光敏液體，在與計算機(jī)控制的紫外線接觸時變成固體。一旦SLA零件凝固了，它們就不能再變回液體；這個過程是不可逆的。

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.選擇性激光燒結(jié)(SLS)

2. Selective laser sintering (SLS)

SLS也是一種快速成型制造技術(shù)，適合用于塑料和金屬成型制造。SLS使用高功率的激光來加熱和燒結(jié)粉末層，以創(chuàng)建一個成型。值得注意的是，SLS產(chǎn)品比SLA成型要弱得多。然而，SLS要便宜得多，需要的時間和勞動力更少，同時提供高生產(chǎn)率。SLS零件很粗糙，在獲得終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.材料噴射或熔融沉積成型（FDM）

3. Material Spray or Melt Deposition Molding (FDM)

材料噴射也是一種快速成型制造工藝，速度快，合理，易于使用，而且便宜。FDM好用于產(chǎn)品開發(fā)。FDM使用在打印噴嘴筒內(nèi)熔化的熱塑性塑料絲來創(chuàng)建成型。打印機(jī)通過來回移動噴嘴而工作。通過使用計算機(jī)沉積程序，塑料被分層以形成成型。圖片

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）或選擇性激光熔化（SLM）

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

SLM是常用的快速成型制造類型。這種方法在航空航天、汽車、國防和醫(yī)療公司很受歡迎。它是受歡迎的方法，因為它的成本較低，而且能制造高質(zhì)量的零件。該方法使用高功率或電子束來熔化與粉末分層的粘合劑，以創(chuàng)建生產(chǎn)零件或成型。PBF使用基于動力的材料，如：銅、鋁、不銹鋼。

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.片材層壓或?qū)訅何矬w制造(LOM)

5. Sheet Lamination or Laminated Object Manufacturing (LOM)

與SLS和SLM相比，板材層壓沒有那么復(fù)雜。這個過程不需要你在一個特別控制的環(huán)境中來達(dá)到你想要的結(jié)果。片材層壓的工作成理是利用激光束將一層層的金屬、塑料和陶瓷切割物放在一起，以創(chuàng)造出所需的CAD設(shè)計。每一層都用膠水粘合起來，直到整個部件完成。然而，這種方法是勞動密集型的，需要大量的時間。

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.數(shù)字光處理(DLP)

6. Digital Light Processing (DLP)

DLP與SLA方法幾乎相同。DLP使用的是樹脂聚合，使用一束光進(jìn)行固化。DLP的光源來自投影儀，而SLA的光源則來自激光束。DLP比SLP更便宜、更快速，但它在后期固化方面需要更多基礎(chǔ)設(shè)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.

快速成型制造確保不需要昂貴的工具和設(shè)置。同樣的3D打印機(jī)可用于生產(chǎn)不同幾何形狀的成型。它大限度地減少了設(shè)計缺陷和錯誤。您對此有什么疑惑或者需求，歡迎您來我們網(wǎng)站http://www.faxuemingjia.com咨詢！
