It used to take several weeks or even months to make a prototype with earlier technologies. Today, an SLA prototype can be made within two to three business days, speeding up the product development stage and the time to market. That’s the magic of 3D printing, especially with technologies like stereolithography (SLA). It’s one of the best solutions that allow product designers to go from ideation to end-use production quickly.
SLA 3D printing may be one of the oldest additive manufacturing technologies, but it is still widely used because it offers versatility for prototyping and low-volume end-use production. It builds parts layer per layer with a photosensitive resin that solidifies when exposed to a highly precise UV laser. This results in accurate parts with a good surface finish, which can be enhanced with post-process finishing. Although building an SLA prototype requires support structures, these are removed after printing.
Given its versatility and process, SLA 3D printing has contributed to the evolution of product design. Keep reading to explore how and why.
More material options
SLA prototypes can be built with a wide range of materials that come in specific colors, including generic resin (white), rigid (black), and high-toughness resin (light green or yellow). It’s also possible to build a transparent prototype with a special resin.
Various surface finishes
In prototyping, the goal is to make the model as identical as possible to the final product to allow precise testing and aesthetics. An SLA prototype will have a good surface finish, but it can be further improved with post-processing to be smoother or in a different color. SLA 3D printing specialists in China offer paint, dye, chrome plate, and smooth finishes.
Build complex shapes
Manual prototyping techniques won’t usually guarantee precise results, especially when crafting complicated geometries. That’s not a problem with an automated 3D printing process like stereolithography. Modern SLA technologies meet tolerances of +/- 0.001” or +/- 0.004” per inch, whichever is greater, whether printing high-resolution or normal prototypes. This ensures more precise results, even for prototypes with complex shapes.
