Can SLA Be Used for Producing High-Strength Resin Parts, and What Are Its Advantages?

SLA for High-Strength Functional Components

Yes, Stereolithography (SLA) can be used to produce high-strength resin parts when combined with engineering-grade resins. Modern SLA materials such as tough resins, durable resins, and high-temperature resins allow SLA to go beyond prototyping and deliver parts that perform in mechanical assemblies, fixtures, or functional end-use conditions.

Key Advantages of SLA for High-Strength Resin Parts

1. Excellent Mechanical Performance

With the right resin selection, SLA parts can achieve:

• Tensile strength: 55–65 MPa

• Elongation: 10–50%

• Impact resistance similar to ABS or polypropylene

These properties make SLA suitable for clips, housings, jigs, and load-bearing structures.

2. High Resolution and Dimensional Accuracy

SLA offers ultra-fine detail with tolerances down to ±50 µm and layer heights as small as 25 µm. This precision supports snap-fit features, thin walls, threaded holes, and sealing geometries.

3. Smooth Surface Finish

The photopolymer curing process results in smooth surface textures (Ra 1–2 µm) directly out of the printer, reducing the need for extensive post-processing and allowing direct use in applications like fluid contact, optical components, or cosmetic surfaces.

4. Diverse Engineering Resin Options

High-strength SLA resins are available to meet various needs:

• Tough resins for mechanical stress and impact resistance

• Durable resins for fatigue and deformation

• High-temperature resins for thermal stability

• Biocompatible resins for skin- or body-contact medical devices
