Our team works with industrial-grade systems and professional resin materials to deliver accurate, reliable parts for prototyping and product development. With hands-on experience across multiple industries, we focus on quality, consistency, and dependable manufacturing results businesses can trust.
What is SLA 3D Printing?
SLA 3D printing, also known as stereolithography, is a precision additive manufacturing process that creates detailed plastic parts from liquid photopolymer resin. A UV laser cures the resin layer by layer according to a digital 3D model, forming a solid object with high accuracy and smooth surface finish.
Key features
• Produces smooth surfaces and fine details
• Achieves high dimensional accuracy
• Creates complex and intricate geometries
• Supports multiple resin materials for different applications
• Ideal for rapid prototyping and product development
Advantages of SLA 3D Printing
SLA continues to lead when precision and surface quality are non-negotiable. Here is why businesses choose it for high-stakes applications.
High Resolution Printing
Achieves layer resolutions as fine as 25µm, capturing intricate details, thin walls, and sharp edges with consistency.
Smooth Surface Finish
Parts come off the build platform with a near-injection-mold surface quality — ideal for presentation models and end-use components.
Tight Dimensional Accuracy
Tolerances of ±0.1mm are standard. Functional fits, threads, and snap-fits behave as designed — no guesswork on critical dimensions.
Complex Geometries
Internal channels, overhangs, lattice structures, and organic shapes are printed without compromise — where other methods struggle, SLA excels.
SLA 3D Printing Materials
The performance of an SLA printed part depends on the resin material used. Different photopolymer resins are designed to deliver specific properties such as strength, flexibility, clarity, or heat resistance, allowing parts to match the needs of various applications.
Standard Resin
General purpose resin for prototypes, models, and display parts with excellent surface quality.
Tough / ABS-Like
Mimics the behaviour of ABS thermoplastic. Ideal for snap-fit parts and durable prototypes.
Flexible / TPU-Like
Soft rubber-like material suited for wearables, gaskets, grips, and ergonomic testing.
Clear / Transparent
Produces near-glass transparency after polishing. Used for lenses and display parts.
High-Temp Resin
Withstands temperatures up to 289°C. Suitable for mould tooling and electronic housings.
Dental / Bio-Compatible
Used for surgical guides, dental models, and orthodontic devices.
Applications of Stereolithography
SLA 3D printing is widely used in industries that require high precision, smooth surface finish, and detailed parts. Because stereolithography works with very fine layers, it can produce complex shapes and professional-quality components suitable for prototyping, testing, and specialized manufacturing.
Product Prototyping
Engineers and designers use SLA printing to quickly create accurate prototypes for design validation, product testing, and concept development before moving to full production.
Medical and Dental Models
Stereolithography is commonly used to produce detailed anatomical models, dental molds, surgical guides, and orthodontic components that require high precision.
Jewellery Casting Patterns
SLA printing allows jewelers to create intricate casting patterns with fine details, making it ideal for rings, custom ornaments, and complex decorative designs.
Engineering Components
Functional parts such as brackets, housings, jigs, and fixtures can be produced with tight dimensional accuracy, making them suitable for engineering and assembly testing.
Miniatures and Scale Models
High-resolution SLA printing is perfect for architectural models, figurines, collectibles, and detailed scale models where surface quality and fine features are important.
SLA vs FDM 3D Printing
Both SLA and FDM are widely used additive manufacturing technologies, but they are designed for different purposes. The choice between them usually depends on whether the priority is high precision and surface quality or faster production with lower material cost.
SLA — Stereolithography
- Produces very smooth surfaces with minimal visible layer lines
- High resolution printing with fine details and small feature sizes
- Excellent dimensional accuracy for complex geometries
- Parts can achieve consistent mechanical properties after proper curing
- Best suited for detailed prototypes, medical models, jewellery patterns, and presentation parts
- Produces very smooth surfaces with minimal visible layer lines
- High resolution printing with fine details and small feature sizes
- Excellent dimensional accuracy for complex geometries
- Parts can achieve consistent mechanical properties after proper curing
- Best suited for detailed prototypes, medical models, jewellery patterns, and presentation parts
Stereolithography Design Guidelines
| Parameter | Recommended Value | Design Notes |
|---|---|---|
| Minimum Wall Thickness | ≥ 0.4 mm | Thin walls may deform or break during printing or post-processing. |
| Minimum Feature Size | ≥ 0.2 mm | Fine details print best at higher resolution settings. |
| Vertical Hole Diameter | ≥ 0.5 mm | Small holes may close during printing, so design slightly larger. |
| Dimensional Tolerance | ±0.1 mm | Tight assemblies may require test prints or adjustments. |
| Escape Holes | ≥ 3.5 mm | Allows uncured resin to drain from hollow parts. |
| Embossed Text | ≥ 0.5 mm | Raised text should be deep enough to remain visible after finishing. |
