What is SLA 3D Printing?
Stereolithography - more commonly referred to as SLA 3D printing - is one of the most popular and widespread techniques in the world of additive manufacturing. It works by using a high-powered laser to harden liquid resin that is contained in a reservoir to create the desired 3D shape. In a nutshell, this process converts photosensitive liquid into 3D solid plastics in a layer by-layer fashion using a low power laser and photopolymerization.

Every standard SLA 3D printer is generally composed of four primary sections:
* A tank filled with the liquid photopolymer: The liquid resin is usually a clear and liquid plastic.
* A perforated platform immersed in a tank: The platform is lowered into the tank and can move up and down according to the printing process.
* A high-powered, ultraviolet laser
* A computer interface, which manages both the platform and the laser movements
