Stereolithography was the first process developed for rapid prototyping, and though it is among the oldest 3D printing methods, it is still very popular today.
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 is stereolithography in dentistry?
 This allows for the production of complex shapes with internal detail and undercut areas. One such method is stereolithography, which produces three-dimensional objects by curing a liquid resin under a computer-guided laser.
What is the principle behind stereolithography?
The basic principle of Stereolithography is the selective curing of a photopolymer (a resin) using a UV laser. A thin layer of liquid resin (generally 50-100 microns deep) is prepared in the machine’s building space. The Laser draws a pattern on that layer curing only the shape desired in the first layer of the model.
Where is fused deposition modeling used?
Fused deposition modeling (FDM) is one of the most widely used additive manufacturing techniques. It has been utilized in the automobile industry, ranging from testing models, lightweight tools to final functional components.
Which laser is used to cure stereolithography?
Stereolithography (SLA) or vat polymerization uses single or multiple laser beams from a UV laser to cure thin layers of photopolymer resins [38,39]. The beam from the UV-laser source is controlled through the desired path and is made incident on the resin reservoir.
What are the desirable features of stereolithography resin?
SLA provides the tightest dimensional tolerances of any rapid prototyping or additive manufacturing technology: ± 0.005″ (0.127 mm) for the first inch, and an additional 0.002″ for each additional inch. Print surfaces are smooth. Build volumes can be as high as 50×50 ×60 cm3 without sacrificing precision.
How do stereolithography printers 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.
What products are made from stereolithography?
- Standard resins, for general prototyping.
- Engineering resins, for specific mechanical and thermal properties.
- Dental and medical resins, for biocompatibility certifications.
- Castable resins, for zero ash-content after burnout.
What is stereolithography SLA used for?
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. A wide selection of materials, extremely high feature resolutions, and quality surface finishes are possible with SLA.
Which technology parts are built fully cured?
PolyJet parts are built fully cured. PolyJet supports are created out of a separate material specially formulated to release from the final part with water blasting and some hand labor. While PolyJet parts offer a smoother surface right off the build, Stereolithography parts offer a much easier to sand surface.
Why is Binder 3D faster than direct 3D printing?
Binder 3-D printing has a few advantages over direct 3-D printing. First, it tends to be faster than direct printing because less of the material is applied through the nozzles. Another advantage is that you can incorporate a wider variety of colors and materials in the process, including metals and ceramics.
