One of the most popular and versatile technologies offered by most of the leading engineering companies which can be utilized for producing concept models, single presentation models and experts for use in vacuum casting. Stereolithography (SLA rapid prototyping) is a 3D printing process which is used for additive manufacturing and rapid prototyping.

Stereolithography Process

SLA prototyping is a 3D printing process utilized in fast prototyping and is normally utilized from the get-go in the item improvement process as an idea or irregular introduction models and experts.

It produces parts with great quality smooth surface complete, amazing optical lucidity, high exactness and thin, straight, vertical dividers. The scope of materials that can be utilized takes into consideration a scope of resistances and property versatility.

Stereolithography, ordinarily alluded to as SLA, utilizes a laser to harden a photopolymer gum building parts layer by layer. Stereolithography (SLA) is an extraordinary decision for complex model geometries on account of the exactness to which it fabricates and the capacity to apply a huge number of completions.

Stereolithography (SLA) is characterized as Vat Polymerization and is one of the seven procedures characterized by ASTM F42. Met-L-Flo, Inc. utilizes our vast limit Stereolithography frameworks, and also our ability in show completing, to deliver quality models of your direct computerized fabricating outlines in a quickened time period. These examples are fantastic for Silicone moulds and auxiliary tooling application, for example, Rubber Plaster Molding and investment casting.

Stereolithography: Principle and Process

•    This depends on specific polymerization of a photosensitive pitch utilizing ultraviolet rays.

•    In this framework, an ultraviolet laser beam is centred around the best layer of photosensitive pitch contained in a vat.

•    The beam is positioned and moved in level X and Y headings to polymerize the gum inside the boundary a specific cross-area.

•    The cured layer of polymer is brought by a stage connected down to it, with the goal that a crisp layer of fluid pitch covers the restored layer.

Benefits and Drawbacks of Stereolithography


•    Accomplishing accuracy in businesses.

•    Share Market and Industry presence.

•    Prepared to do high detail and thin walls.

•    Great surface finishing.


•    Requires post-restoring.

•    Some warpage, shrinkage and twist because of stage change.

•    Restricted materials (Photopolymers).

•    Support structures constantly required. Expulsion of support structures can be troublesome.

Rapid Prototyping

In the least complex of terms, rapid prototyping is the expedient formation of models that are outwardly as well as practically assessed while the item advancement process. Rapid prototyping might be rehashed on various occasions as an outline is idealized.

Despite the fact that the expressions "3D printing" and "rapid prototyping" are every so often utilized conversely, the previous is the procedure and the last the final product.

From multiple points of view, additive manufacturing is the ideal procedure for rapid prototyping. It encourages the brisk and effective refining of client encounters into a mockup, making it conceivable to rapidly create and assess a 3D-printed model. Thoughts accumulated from rehashed criticism cycles yield included refinements that are immediately joined into resulting iterations.
