Why is stereolithography SLA?

Stereolithography (SLA) is an additive manufacturing process that can 3D print parts with small features, tight tolerance requirements, and smooth surface finishes.

What does SLA stand for stereolithography?

What Does Stereolithography (SLA) Mean? Stereolithography (SLA) is an additive manufacturing process that builds solid prototypes, patterns and products from CAD drawings. SLA enables the construction of solid plastic prototypes that are weaved from a CAD-powered laser beam gun.

What’s the difference between SLA and SLS?

SLA works with polymers and resins, not metals. SLS works with a few polymers, such as nylon and polystyrene, but can also handle metals like steel, titanium, and others. SLA works with liquids, while SLS uses powders that raise safety concerns. Breathing in fine particulates of nickel, for example, can be harmful.

What does SLA stand for?

SLA stands for service-level agreement and is a document that defines the level of service expected during an exchange between a receiver of service and a service provider.

How does stereolithography SLA 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 materials are used in stereolithography?

Stereolithography is a laser-based technology that uses a UV-sensitive liquid resin. A UV laser beam scans the surface of the resin and selectively hardens the material corresponding to a cross-section of the product, building the 3D part from the bottom to the top.

Why do desktop stereolithography SLA systems use an inverted configuration?

Inverted SLA printing introduces peel forces that affect the print as it separates from the surface of the tank, so the build volume is limited and sturdy support structures are required. The Formlabs Form 2 is heavily calibrated to account for the forces of the peel process and produce high quality parts.
