Stereolithography (SLA) Printing
It can be used for the creation of prototypes for new product development, medical sector and has many more applications with a relatively lower price.
SLA 3D Printing
Stereolithography technique is an additive manufacturing process that is used for creation of parts layer by layer through the use of photochemical processes. In this process, chemical monomers and oligomers are cross linked to form polymers. An ultraviolet laser is focused on a vat of photopolymer resin with the help of a CAD software. The resin is solidified photochemically and a single layer of the desired part is formed. After that, one layer is lowered by the build platform and the tank is coated with the resin again. This process is repeated again and again until the part is completed. After the completion, the part is washed with the solvent in order to remove the resin off the surface. It is a very widely used 3D printing technology.
Major Benefits :
- Lower cost
- Lesser print time
- Large built size
- Widely available
- Smooth finish
Uses :
It can be used for the creation of prototypes for new product development, medical sector and has many more applications with a relatively lower price.
Medical Sector
SLA can be used in the creation of 3D model of the various regions of the patient’s body through the use of CT and MRI scans and subsequently it can help in the planning and designing and manufacturing of the implant.
Prototype Creation
This technique is widely used for the creation of prototypes in a relatively low price and high accuracy. It can be used for the creation of complex shapes.
