Why Choose Resin 3D Printing for High-Precision Parts?
Resin 3D printing has transformed how industries produce high-detail, functional, and visually stunning parts. Unlike filament or powder-based technologies, resin printing delivers exceptional surface finish, fine feature resolution, and versatile material properties that make it ideal for prototypes, functional components, and end-use production.
Stratasys's resin 3D printing technologies—SLA, P3 DLP, and PolyJet—offer unique advantages tailored to different production needs, from speed and precision to multi-material functionality.

Stereolithography for Precision and Surface Quality
Stratasys® SLA
Technology Overview:
Stereolithography (SLA) uses a laser to cure photopolymer resin layer by layer, producing parts with micron-level accuracy and ultra-smooth surfaces. SLA is the go-to choice when detail, dimensional fidelity, and surface finish are critical.
Why SLA Stands Out:
- Unmatched Detail: Perfect for dental models, jewelry, medical devices, and intricate engineering parts.
- Smooth Surfaces: Minimal post-processing required, often suitable for direct use.
- Consistent Accuracy: Excellent repeatability across multiple prints.
- Material Variety: Wide selection of engineering resins for mechanical strength, heat resistance, and biocompatibility.
- Scalable Production: Modern SLA systems like the Stratasys Neo series allow batch production without compromising quality.
Ideal Applications:
Functional prototypes with tight tolerances
High-detail consumer and industrial products
Automotive and Motorsport components

Rapid, High-Fidelity Production
Stratasys® P3 DLP
Technology Overview:
Stratasys’ P3 (Programmable Photopolymerization) DLP technology uses digital light processing to cure entire layers of resin simultaneously. This approach accelerates build times while maintaining exceptional accuracy and surface quality.
Why P3 DLP Stands Out:
- Fast Production: Layers cure all at once, significantly reducing print times compared to traditional SLA.
- High Geometric Fidelity: Maintains sharp features and smooth surfaces for small and complex parts.
- Open Material Ecosystem: Compatible with a broad range of resins, from rigid engineering polymers to flexible materials.
- Repeatable Results: Ideal for medium to high-volume production runs with consistent quality.
Ideal Applications:
Functional prototypes and small batch production
Complex geometries for consumer and industrial products
Rapid production where speed cannot compromise detail

Multi-Material, Multi-Color Capabilities
Stratasys® PolyJet
Technology Overview:
PolyJet takes resin 3D printing to the next level by jetting multiple photopolymer droplets simultaneously, instantly curing them with UV light. This enables parts with multiple materials, colors, and textures in a single print.
Why PolyJet Stands Out:
- Multi-Material Printing: Combine flexible, rigid, and transparent materials in one build.
- High-Resolution Detail: Supports fine features, thin walls, and smooth surface finishes.
- True-to-Life Prototypes: Perfect for realistic product models, functional assemblies, and soft-touch components.
- Fast Iteration: Quickly produce complex prototypes or parts without assembly.
- Healthcare Applications: Produce medical-grade parts with smooth surfaces and precise geometries.
Ideal Applications:
Realistic product prototypes for consumer testing and marketing
Multi-material assemblies
Medical and dental models with functional and aesthetic requirements

Why Choose Resin 3D Printing Over Other Technologies?
- Superior Surface Quality: Smooth finishes reduce sanding and post-processing.
- High Feature Resolution: Resin printing captures intricate geometries, thin walls, and fine details.
- Material Flexibility: Photopolymer resins offer a wide spectrum of mechanical, thermal, and optical properties.
- Multi-Material & Color: PolyJet enables combining materials and colors in one part, impossible for powder or filament-based methods.
- Faster Prototyping for Functional Parts: Especially with P3 DLP, you get high-quality parts at high speed.
Resin printing is the choice when quality, detail, and versatility are non-negotiable, making it ideal for medical, dental, consumer products, and functional engineering prototypes.
