Stereolithography (SLA) 3D printing is the most common resin 3D printing process that has become vastly popular for its ability to produce high-accuracy, isotropic, and watertight prototypes and end-use parts in a range of advanced materials with fine features and smooth surface finish.
Is SLA printing better than FDM?
In general SLA 3d prints are much slower than FDM prints. Due to the small surface area of the laser it takes longer to build each layer. With FDM you can choose the layer heights which allows for much faster and more flexible 3D printing. But at the same time the surface quality of an SLA print will be smoother.
What materials can SLA print?
SLA 3D printers use light-reactive thermoset materials called “resin.” When SLA resins are exposed to certain wavelengths of light, short molecular chains join together, polymerizing monomers and oligomers into solidified rigid or flexible geometries.
How does SLA printing works?
How does stereolithography work ? SLA 3D printing works by first positioning the build platform in the tank of liquid photopolymer, at a distance of one layer height for the surface of the liquid. A UV laser creates the next layer by selectively curing and solidifying the photopolymer resin.
Is resin stronger than FDM?
FDM prints are generally stronger than 3D resin prints. Specifically, the tensile strength of FDM prints ranges from 38-64MPa, while those of resins are generally lower at 23-55Mpa. Also, FDM prints have higher flexural strengths at 2.1-7.6GPa, while resins only average at 60.6MPa.
