Which 3D Printing Technology Is Best for Producing High-Precision Resin Parts?

Optimal Technology: Vat Photopolymerization (SLA and DLP)

Vat Photopolymerization, specifically Stereolithography (SLA) and Digital Light Processing (DLP), is the best 3D printing technology for producing high-precision resin parts. Both methods cure photopolymer resin layer by layer using light, delivering excellent resolution, fine detail, and smooth surface finishes. This makes them ideal for applications in prototyping, medical devices, dental models, and miniature components.

• SLA uses a laser to trace and cure each layer individually.

• DLP projects an entire layer at once using a digital light source, offering faster builds with high accuracy.

Key Advantages for High-Precision Resin Parts

• Dimensional accuracy: ±25–50 µm

• Surface finish: Ra 1–2 µm without post-processing

• Layer resolution: As fine as 25 µm

• Ideal for microfeatures, thin walls, and tight-tolerance components

Compatible High-Precision Resins

• Standard Resins – for general prototyping and visual validation

• Tough Resins – for functional parts requiring impact resistance

• Engineering Resins – for parts under load or with mechanical stress

• Medical-Grade Biocompatible Resins – for surgical guides and dental use
