Stereo Lithography Apparatus(SLA)
Print your SLA parts with fast turnaround and wide variety of resin materials as fast as 2-3 days!
Overview: How SLA 3D Printing Works?
The Basics of SLA 3D Printing
Stereo Lithography Apparatus (SLA) is a powerful 3D printing technique ever developed. It produces highly accurate and high-resolution, detailed parts. It’s used directly in end-use, low-volume production, or for prototyping. Unionfab offers over 30 uniquely engineered SLA materials to enable products to the market at reduced production costs.
Benefits of SLA 3D Printing
One of the advantages of Stereo Lithography Apparatus is its speed; functional parts can be manufactured within a day.
The length of time it takes to produce a single part depends upon the complexity of the design and the size. Printing time can last anywhere from hours to more than a day.
Prototypes and creations made with stereolithography are strong enough to be machined and can also be used to make master patterns for injection molding or various metal casting processes.

Features of SLA 3D Printing
Advantages
Surface & Detail
SLA has tolerances of +/-.004” per inch, and resin surface is ideal for post-processing like polishing and painting.
Cose Saving
SLA is one of the cheapest method for rapid prototyping while preserving a good surface quality and accuracy.
Geometry
SLA allows to integrate multiple components as well as thin-walled objects and intricate geometries that traditional method won’t be capable of.
Turnaround
SLA 3D printed parts do not require tooling which reduces the manufacturing lead time from weeks to days, allowing for faster innovation and speed to market.
Material Selection
There're various material with special properties like toughness, heat resistance, flexibility, which simulates the end products.
Scalable Volume
Multiple, identical parts can be built on a single platform at one time, greatly increasing production efficiency.
Drawbacks
Durability
Photopolymers are not stable over time and most resins don’t have balanced impact/heat resistance.
Scale Effect
The unit cost and lead time will not be reduced as much as casted or molded parts.
