Liquid State-Based AM Processes
Liquid State-Based Additive Manufacturing processes, primarily Stereolithography (SLA), utilize photopolymerization to create three-dimensional objects layer by layer. This method is characterized by precise control of a UV laser to cure photopolymer resins, allowing for the production of complex geometries and fine surfaces. Additionally, the chapter explores the advantages and disadvantages of SLA, along with its applications in various fields such as dental and medical devices, rapid prototyping, and microfluidics.

What we have learnt
- Stereolithography (SLA) is an effective additive manufacturing technique that works through photopolymerization.
- SLA allows for high-resolution 3D printing, making it suitable for complex and intricate designs.
- Post-processing is required in SLA to ensure the final products have the appropriate strength and finish.
Key Concepts
- -- Stereolithography (SLA)
- A vat photopolymerization-based additive manufacturing technique that forms objects by selectively curing liquid resin with a UV laser.
- -- Photopolymerization
- The process of curing liquid resins by exposure to UV or visible light, converting them into solid polymer networks.
- -- Microstereolithography (μSLA)
- A technique enabling sub-micron resolution fabrication, suitable for micromechanical systems and biomedical applications.
- -- Layer Thickness
- The thickness of each layer in the SLA process, typically ranging from 25 to 100 microns.
- -- PostProcessing
- The stage after printing that includes cleaning, curing and support removal to enhance the object's properties.
