SLA 3D printing technology is a form of additive manufacturing that uses photopolymerization to create three-dimensional objects. In SLA printing, a liquid photopolymer resin is cured using a laser to create the desired shape. This technology has been around since the mid-1980s and has advanced significantly since then, making it a popular choice for creating intricate and high-resolution parts.

How SLA 3D Printing Technology Works

The process of SLA 3D printing begins with a digital model of the desired object. This model is created using 3D modeling software or obtained from a 3D scanner. The model is then sliced into thin layers using specialized software, and the resulting 2D slices are sent to the SLA printer.

The SLA printer works by using a laser to cure a liquid photopolymer resin. The resin is contained in a vat and is spread out in a thin layer using a build platform. The laser is then directed at the resin, curing it in the desired shape for each layer. The build platform then moves down, and the process is repeated, layer by layer, until the object is complete.
