3D Druck Service - Stereolithography (SLA)

Stereolithography (SLA)

Stereolithography (SLA) is a 3D printing process that uses UV light to cure liquid resin (photopolymer) layer by layer. The process enables very smooth surfaces, extremely fine details, and the precise realization of complex structures and geometries with high dimensional accuracy. This makes SLA ideal for high-resolution prototypes, design models, applications in dental and medical technology, jewelry manufacturing, and precise functional and visual parts.

Standard service – The component is cleaned, freed from support structures and post-cured by UV light. The result is a dimensionally accurate part with a smooth surface and fine details, ideal for prototypes as well as design and display models.

Material Selection for SLA

When selecting materials for SLA (stereolithography), the intended use of the component is crucial. SLA resins differ primarily in mechanical properties, temperature resistance, surface quality, and biocompatibility.

Nylon-GF

SLA

Nylon GF is a glass-fiber reinforced plastic with high strength and rigidity. The components are resilient, temperature-resistant, and dimensionally stable. Ideal for functional prototypes and technical components where stability and precision are important.

8K Resin

SLA

This resin is ideal for precise, dimensionally stable technical components. It offers a smooth surface, high detail accuracy, and reliable stability for functional prototypes and simple construction parts.

8K ABS Resin

SLA

This resin is ideal for precise, dimensionally stable technical components with increased stability. It offers a smooth surface, high detail accuracy, and robust, ABS-like material properties – perfect for functional prototypes and durable construction parts.

Clear resin

SLA

This resin is ideal for components that require high transparency, clean surfaces, and precise details. Perfect for light guides, design models, fluid containers, and technical components with a viewing function.

SLA 3D Printing: Advantages and Disadvantages at a Glance

Benefits

Resolution - Very high detail resolution and dimensional accuracy, extremely smooth surfaces.

Complex shapes possible – Cavities, lattice structures, and moving parts in one print.

Fast production – Your parts are usually ready for shipment in 1.5–4 days.

Small series and individual pieces – from one part to many components, efficiently producible.

Accuracy - Very high precision with tolerances from ±0.01 mm to ±0.05 mm

Wide color palette - diverse design options and the possibility of individual color matching.

Material – a diverse selection of different material types.

Disadvantages

Material Properties - Materials are usually more brittle than with other 3D printing processes.

Design Limitations - Support structures are necessary.

Durability - Lower temperature and UV resistance than engineering plastics.

Color Options - Only one color per printed part is possible; no multicolor printing.
