We all know that there are many methods of 3D printing, such as SLA, SLM, SLS, and so on. 

Each technology has its own characteristics. This blog post will introduce SLA 3D printing technology.

SLA technology, which stands for Stereolithography Appearance, uses laser focused on the surface of photosensitive material to solidify it from point to line, from line to surface in sequence, layer by layer, to form a three-dimensional solid.

SLA technology is mainly used for manufacturing various molds, models, etc. 

It can also be used in precision casting by adding other components to the raw material, using SLA prototypes instead of wax molds in precision casting. 

SLA technology has fast forming speed and high accuracy, but due to the shrinkage during resin curing process, stress or deformation is inevitably generated. 

Therefore, the development trend is to develop light-sensitive materials with small shrinkage, fast curing, and high strength.

Advantages of SLA:

• SLA is the earliest rapid prototyping technology with high maturity, tested over time.

• Prototypes are directly made from CAD digital models, with fast processing speed, short product production cycle, and no need for cutting tools and molds.

• It can process prototypes and molds with complex structures or difficult to be formed by traditional methods.

• It visualizes CAD digital models, reducing the cost of error correction.

• It provides samples for experiments and can verify and check the results of computer simulation calculations.

• It can be operated online and remotely controlled, conducive to production automation.

Applications of SLA rapid prototyping technology: SLA prototype

• Medical field: SLA technology is widely used in the medical field, such as medical device development, dentistry, biomedical research, etc.

  For example, dental enthusiasts can use SLA technology to manufacture orthodontic appliances, retainers, etc., and can be personalized.

• Automotive manufacturing: In the automotive manufacturing field, SLA technology can be used to manufacture product models, product external systems, internal components of automobiles, etc.

• Electronics industry: SLA technology can be used to manufacture electronic product casings, etc.
