Overview: How SLA 3D Printing Works?
The Basics of SLA 3D Printing:
Stereolithography (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.

Features of SLA 3D Printing
Cost 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.
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.

SLA 3D Printing Applications
Prototypes
With SLA, the prototype can be made using nylon material with great functionality. Fast turnaround makes it a good choice for functional prototyping.
Customized Products
The speed and versatility of SLA let variable production of customized gifts/samples for different users become possible.
Batched Products
SLA can be applied to make high-quality small batched products from 1-10,000 units, ideal for small businesses that wishes to test the market’s reaction to their newly developed products.
