In 1986,Doctor Charles W Hull mentioned in one of his papers the concept of using laser to find the surface of photopolymer resin and solidify three-dimensional objects.
After that, Charles Hull applied for related patents. In 1986, the rudiment of SLA appeared, and SLA became the first prototyping technology that accomplished the commercial application. In 1988,the company 3D systems made the first SLA 3D printer-SLA 250 and commercialized it. And since that SLA printers spring up all over the world.
Very mature technology since it is the earliest 3D printing technology
High quality of surface and accuracy (about 0.1mm)
Various printing materials. With a wide range of functional materials, you can choose the most suitable one according to your own need.
The prototype is directly generated from the CAD data, which has the advantages of fast processing speed, short production cycle and no need for the cutting tools to do the secondary processing.
SLA can be applied for:
Customization on a large scale, for example material for dental hospital
Ideal for quick cast, to build part that is thin-walled and hollow in the core
Thanks to its high accuracy, it can be used for making high precision tools and measuring tools
Digital manufacturing, with the high precision, it can be used for manufacturing and assembling. Besides, with the repeatability, SLA printer make it possible for making large amount of parts,
With the high accuracy and repeatability and fine surface, the parts that printed by SLA printers are perfect prototypes for function testing.
for industries such as Aerospace ,Military , Automobile, Consumer Goods, Electrical Appliances and so on.
And now let me introduce our company SEEWE that especially focus on SLA 3d printer.
