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.
What is stereolithography 3D printing?
Stereolithography (SLA) is an industrial 3D printing process used to create concept models, cosmetic prototypes, and complex parts with intricate geometries in as fast as 1 day.
What does stereolithography mean?
Stereolithography (SL) is one of several methods used to create 3D-printed objects. It’s the process by which a uniquely designed 3D printing machine, called a stereolithograph apparatus (SLA) converts liquid plastic into solid objects.
What is the difference between stereolithography and 3D printing?
SLA, or stereolithography, is a method of 3D printing that utilizes a laser and resin. That’s right, with SLA you are essentially 3D printing upside-down. Most SLA machines will use a UV laser and UV-curing resin, which makes the setup and post-printing processes difficult due to ambient UV light.
Why is it called stereolithography?
The term stereolithography was coined by Charles (Chuck) W. Hull, who patented the technology in 1986 and founded the company 3D Systems to commercialize it. Hull described the method as creating 3D objects by successively “printing” thin layers of a material curable by ultraviolet light.
What are the disadvantages of stereolithography?
Limitations of stereolithography Fragility: stereolithography uses equivalent materials which are resins. Expensive machines: if we had predicted the boom in 3D printing in the past few years, experts have neglected the cost of the machines and the difficulty of their operation.
What can stereolithography be used for?
Stereolithography can be used to create prototypes for products in development, medical models, and computer hardware, as well as in many other applications. While stereolithography is fast and can produce almost any design, it can be expensive.
Who uses stereolithography?
Stereolithography is well used for creating accurate 3D models of anatomical regions of a patient, used to aid in diagnosis and for pre-planning and implant design and manufacture. It is also good for use in concept models and scale models.
What are the advantages and disadvantages of stereolithography?
Advantages and limitations of stereolithography It’s quick. It’s cheap. It aids prototyping. It’s a multi-material process. It creates tools, quickly. High quality parts. Snap-together assemblies. Scaling is easy.
What are the advantages and disadvantages of stereolithography process?
Fast implementation of prototypes in early stages of product development. Single-stage production process produces smooth surfaces even without finishing. Low material consumption: non-hardened synthetic resin can be reused. Production of both flexible and rigid 3D objects.

What is the cheapest 3D printing method?
Material Extrusion devices are the most commonly available – and affordable – types of 3D printing technology globally. You might be familiar with them as fused deposition modeling or FDM. They are also sometimes referred to as fused filament fabrication or FFF.
Which is better SLS or SLA?
Whilst SLA might be better for small features – SLS has the advantage over SLA in that the surrounding powder provides support to the parts during the build process. With SLS the powder supports the part, allowing complex geometries and channels to be built which might not be possible to build without supports in SLA.
How does stereolithography 3D printing work?
It works by using a high-powered laser to harden liquid resin that is contained in a reservoir to create the desired 3D shape. In a nutshell, this process converts photosensitive liquid into 3D solid plastics in a layer-by-layer fashion using a low-power laser and photopolymerization.
Which liquid is used in stereolithography?
The unique 3D printing machine also referred to as stereolithography apparatus converts liquid plastic into solid objects. The implementation of stereolithography is fair, though there are many different variations which it is used. The liquid used in this process is photopolymer resin.
Which company invented stereolithography?
3D Systems SLA-1 3D Printer | 1987 Chuck Hull developed stereolithography in 1983 and formed 3D Systems to manufacture and market a commercial printer.
What are the advantages of using additive manufacturing?
Top Ten Advantages of Additive Manufacturing The Cost Of Entry Continues to Fall. You’ll Save on Material Waste and Energy. Prototyping Costs Much Less. Small Production Runs Often Prove Faster and Less Expensive. You Don’t Need as Much On-Hand Inventory. It’s Easier to Recreate and Optimize Legacy Parts.
What do you mean by additive manufacturing?
Additive manufacturing (AM) or additive layer manufacturing (ALM) is the industrial production name for 3D printing, a computer controlled process that creates three dimensional objects by depositing materials, usually in layers.
How does fused deposition Modelling work?
Fused deposition modeling (FDM) is a technology where the melt extrusion method is used to deposit filaments of thermal plastics according to a specific pattern. Similar to 3DP, the layout for FDM consists of a printhead able to move along X and Y directions above a build platform.
Which type of laser is used in stereolithography?
Stereolithography systems use ultraviolet lasers to solidify liquid resin into the desired form as defined by the CAD file.
What is the raw material which is used in stereolithography 3D printing what is the special feature of that material?
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.
What is the difference between fused deposition modeling FDM and Stereolithography STL?
FDM 3D printers form layers by depositing lines of molten material. In SLA 3D printing, liquid resin is cured by a highly-precise laser to form each layer, which can achieve much finer details and is more reliable to repeatedly achieve high-quality results.
What materials can be used in stereolithography?
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.
What are the steps for stereolithography?
How Does Stereolithography Work? A thin layer of photopolymer is exposed above the perforated platform. The computer directs the UV laser to “paint” the layer in the desired pattern. After the layer is fully “painted” and cured, the platform is lowered and the process begins again on the next layer.
