Stereolithography Apparatus(SLA)

Release time:2018-09-05

Introduction:

SLA is the most accurate and versatile rapid prototyping technology. SLA prototypes are constructed from a liquid photopolymer that is selectively cured using an ultraviolet laser.

Due to the accuracy of this processreproduce fine details, SLA models are perfect for use as concept models, form-and-fit studies, functional testing, and as master patterns for a variety of vowin.cn/en/News/news1251.html' target='_blank'>vowin.cn/' target='_blank'>molding techniques.

Highlights:

It is the original Rapid Prototyping technique, and still the most commonly used.
It is comparatively low-cost.
It utilizes a light-sensitive liquid polymer.
It requires post-curing since laser is not intense enough to fully cure.
Extended curing can cause warping.
Parts are somewhat brittle and have a tacky surface.
There is no milling process, so dimensional accuracy can suffer.
Support structures are typically required.
The process is simple: Neither milling nor masking steps are required.
Uncured material should be expected to emit toxic fumes. Thorough ventilation is necessary.

Applications:

When a low number of prototypes is needed (1-10).
Form and fit testing.
Functional testing (for example, snap-fit).
Plastic piece rapid-tooling patterns.
Metal piece rapid-tooling patterns.
Focus group and presentation models.
