Which resin is used in stereolithography?
Stereolithography (STL) (3D systems, USA) is another RP technique to build prototypes using a monomer formulation usually of acrylic- or epoxy-based resin.
What is photocurable?
photocuring (usually uncountable, plural photocurings) The photoinduced hardening of a monomeric, oligomeric, or polymeric substrate, normally using ultraviolet light.
What is SLA resin made of?
SLA Is Special Instead, it uses liquid resins, which are photosensitive mixtures of monomers and oligomers – short chains of carbon molecules that are combined into longer chains during the photochemical process to become hardened plastic.
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.
Which liquid is used in stereolithography?
liquid photopolymers resin
Stereolithography (or SLA) is one of the oldest 3D printing techniques ever developed. This additive manufacturing process is used to 3D print resin material, using a photochemical process. This SLA 3D printing process uses a vat of liquid photopolymers resin that can be cured.
What is the working principle of 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.
What is photocurable resin?
2.3. Photocurable resin (PPF/DEF) was polymerized using a stereolithography system (Lee et al., 2007). PPF is an unsaturated linear polyester that has carbon–carbon double bond cross-linking (Peter et al., 1998). It is degradable by simple hydrolysis of the ester bonds and its product is nontoxic (He et al., 2001).
What industries use stereolithography?
Many industries — from medical to manufacturing — use stereolithography to build prototypes and, on occasion, final products. A car manufacturer, for example, might use stereolithography to create a prototype casting of a car door handle.
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 of the following is used as base material in stereolithography process?
Which of the following is used as base material in Stereolithography (SLA) process? Thermoplastics , Eutectic metals….23.

What are the process parameters of stereolithography?
Stereolithography (SL) is one of the most popular RP process used for rapid tooling applications. There are several process parameters contributing to the strength of an SL product. The contribution of three parameters; namely, layer thickness, post curing time and orientation are most significant.
