Stereolithography (SLA)
RAPID PROTOTYPING & SMALL BATCH PRODUCTION
Rapid prototyping serves as an invaluable tool for businesses aiming to swiftly iterate and test their product designs, enabling them to refine concepts and identify improvements efficiently. For small batch production runs, 3D printing technologies (FDM) and (SLS) provide a cost-effective and agile solution, enabling companies to produce limited quantities of customized components or products without the need for expensive tooling or lengthy setup times
Fused Deposition Modeling
or FDM 3D Printing
FDM printers work by heating a thermoplastic filament to its melting point and then extruding it, layer by layer, to create a three dimensional object.
FDM printers are relatively inexpensive and easy to use, making them a popular choice for home and small-scale 3D printing
Stereolithography (SLA)
Stereolithography works by using a photopolymer resin that is cured by exposure to light.
The machine traces out the desired geometry layer by layer using a computer-controlled moving laser beam.
The beam is directed by mirrors that are positioned around the build platform.
CAD DESIGN & REVERSE ENGINEERING
When it comes to certain projects, a computer-aided design, or CAD, can be extremely beneficial. A main advantage to using CAD is the fact that it provides experts with greater accuracy. This is done by replacing manual drafting with electronic design software, such as SketchUp, Fusion 360, or AutoCAD Design Edition.
Stereolithography is a 3D Printing process which uses a computer-controlled moving laser beam, pre-programmed using CAM/CAD software. Stereolithography (SL) is an industrial 3D printing process used to create concept models, cosmetic - rapid prototypes, and complex parts with intricate geometries in as fast as 1 day.
The technology was invented in 1986 by Charles W. Hull, who co-founded 3D Systems Corp. The first stereolithography machine was capable of creating small two-dimensional shapes. However, over the years the technology has evolved and progressed to where it is today.
Stereolithography works by using a photopolymer resin that is cured by exposure to light. The machine traces out the desired geometry layer by layer using a computer-controlled moving laser beam. The beam is directed by mirrors that are positioned around the build platform.
The build platform is lowered into the vat of photopolymer resin after each layer is cured. This process is repeated until the desired geometry is achieved.
The advantage of stereolithography is that it can create parts with very intricate geometries that would be difficult or impossible to create using traditional manufacturing methods. Additionally, the lead time for stereolithography is much shorter than traditional methods such as milling or machining.
The downside of stereolithography is that it is a relatively expensive technology. Additionally, the material properties of the parts that are produced are not as good as those produced using traditional methods.
Overall, stereolithography is a versatile and powerful technology that has a wide range of applications in industry and research.
How it works? Stereolithography, or SLA 3D printing, is a type of additive manufacturing technology used for creating models, prototypes, patterns, and production parts. SLA 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. The build platform is then lowered by one layer thickness, and the next cross-section is drawn. This process is repeated until the build is complete.
SLA is an acronym for “stereolithography apparatus” or “stereo lithographic apparatus.” It was invented in 1986 by Chuck Hull, who later founded 3D Systems Corporation. The patent for stereolithography (U.S. Patent 4,575,330) was issued in 1986 and expires in 2004.
The key advantage of stereolithography is its accuracy. SLA is capable of producing parts with very fine features and detail, as well as smooth surfaces. Additionally, SLA is one of the fastest additive manufacturing technologies, with some machines capable of printing a layer in as little as 12 seconds.
Resin 3D printing i s often used for creating prototypes and models, as well as for low-volume production. Applications for SLA parts include investment casting patterns, medical devices, and eyewear.
Stereolithography is an amazing tool that can be used to create accurate models of just about anything. Whether you need a prototype for a new product or a 3D model of a patient's anatomy, stereolithography can get the job done quickly and accurately.
This technology is especially useful for pre-planning and implant design. With stereolithography, you can create a 3D model of the patient's anatomy and use it to plan the surgery in advance. This ensures that everything goes according to plan and that the implant fits perfectly.
Stereolithography is also great for creating concept models and scale models. If you need to create a prototype of a new product, stereolithography can help you do it quickly and accurately. And if you need to create a scale model of something, stereolithography can create a perfect replica.
No matter what your needs are, stereolithography is a great tool that can help you achieve your goals. So if you need to create a accurate model of something, don't hesitate to use stereolithography.
In 1986, Charles W. Hull invented stereolithography, which is a 3D printing process that uses a computer-controlled moving laser beam. This technology has helped advance the prototyping and manufacturing process in a variety of industries. Today, stereolithography is used to create concept models, cosmetic prototypes, and complex parts with intricate geometries.
The first stereolithography machine was only capable of creating small two-dimensional shapes. However, over the years the technology has evolved and progressed to where it is today. This technology has helped many companies save time and money on the manufacturing process.
