What Is PolyJet 3D Printing?
PolyJet 3D Printing is a cutting-edge 3D printing technology that falls under the umbrella of additive manufacturing. At its core, the PolyJet process uses photopolymer jetting—a method where tiny droplets of liquid photopolymer resin are jetted onto a build platform. These droplets are then instantly cured (hardened) with UV light, creating thin, precise layers. This layer-by-layer fabrication continues until the final part is complete, making it ideal for rapid prototyping and precision printing of even the most intricate designs. Unlike some other 3D printing methods, PolyJet allows for seamless integration of multiple materials in a single print, opening up endless possibilities for functional and aesthetic parts.

The PolyJet 3D Printing Process
The PolyJet process is a streamlined, step-by-step workflow that ensures accuracy and efficiency from start to finish. Each stage is optimized to deliver high-quality parts with minimal waste.
- Digital Model Creation: Everything starts with a digital model—usually designed using computer-aided design (CAD) software. This model serves as the blueprint for the 3D print.
- CAD File Preparation: The CAD file is checked for errors (like missing surfaces) and optimized for printing. This step ensures the design is compatible with PolyJet technology.
- STL Conversion: The CAD file is converted to an STL (stereolithography) file—a standard format for 3D printing that represents the model as a series of triangular facets.
- Slicing Software: Slicing software breaks the STL file into hundreds or thousands of thin layers (typically 16–100 µm thick). It also adds support structures to hold the part during printing.
- Layer Deposition: The 3D printer jets droplets of photopolymer resin onto the build platform, following the sliced layers. Each layer is cured with UV light immediately after deposition.
- Support Structure Removal: Once printing is complete, the part is removed from the build platform, and support structure removal is done manually or with specialized tools (depending on the part’s complexity).
- Post-Curing: Some parts undergo post-curing—additional UV exposure—to enhance strength and durability, especially for functional components.
Inspection & Quality Control: The final part goes through inspection using tools like calipers or 3D scanners to ensure it meets dimensional requirements. Quality control checks confirm the part is free of defects and ready for use.
PolyJet 3D Printing Materials
PolyJet offers a wide range of photopolymers (resins) to suit different applications, from rigid structural parts to flexible elastomers. The ability to combine materials in a single print makes PolyJet one of the most versatile 3D printing technologies available.
| Material Type | Key Properties | Common Applications |
| Rigid Materials | High strength, impact resistance, heat stability | Automotive brackets, electronic housings |
| Flexible Materials | Elasticity (Shore A hardness 30–95), tear resistance | Grips, gaskets, wearable devices |
| Transparent Materials | Optical clarity (similar to glass or acrylic) | Light covers, lenses, medical fluid containers |
| Opaque Materials | Matte or glossy finish, color stability | Consumer product prototypes, toys |
| ABS-like Materials | Similar to injection-molded ABS—tough, durable | Functional prototypes, tooling |
| Rubber-like Materials | Soft, flexible, and resilient | Seals, bumpers, soft-touch components |
| Bio-Compatible Materials | Approved for contact with human skin/tissue | Dental appliances, surgical guides |
| High-Temperature Materials | Withstands temperatures up to 200°C | Engine components, industrial parts |
| Multi-Material Combinations | Mix textures, colors, and properties in one part | Prototypes with soft grips and rigid bodies |
Surface Treatment for PolyJet Parts
While PolyJet parts already have a smooth surface finish right off the printer, surface treatment can enhance their aesthetic appeal and functional performance. Our post-processing team offers a range of services to meet your specific needs.
- Smoothing: Reduces layer lines for a polished look—ideal for consumer-facing parts.
- Painting: Applies custom colors or finishes (matte, glossy, metallic) to match brand standards.
- Coating: Adds protective layers like UV protection to prevent fading or chemical resistance for industrial parts.
- Plating: Applies metal coatings (chrome, nickel) for conductivity or a premium appearance.
- Sanding & Polishing: Creates a ultra-smooth surface—used for optical parts or high-end prototypes.
- Texturing: Adds patterns (like leather or grip) to improve usability or aesthetics.
- Priming: Prepares parts for painting by ensuring even color absorption.
- Aesthetic Enhancement: Combines multiple treatments (e.g., painting + polishing) for a finished product look.
Functional Coating: Adds properties like anti-microbial protection for medical parts or lubricity for moving components.
PolyJet 3D Printing Tolerances: Precision We Can
Tolerances are critical in 3D printing—especially for parts that need to fit or function with other components. PolyJet excels at high accuracy and tight tolerances, making it a top choice for industries like medical and aerospace.
| Tolerance Factor | Specification | Industry Requirement Match |
| Dimensional Accuracy | ±0.1 mm for parts up to 100 mm; ±0.1% for larger parts | Meets medical device (ISO 13485) and aerospace (AS9100) standards |
| Repeatability | Consistent results across 100+ consecutive prints | Critical for mass customization (e.g., dental aligners) |
| Layer Thickness | 16–100 µm (adjustable based on speed/quality needs) | 16 µm for high-detail parts (jewelry); 100 µm for fast prototypes |
| Tolerance Range | Customizable to ±0.05 mm for precision-critical parts | Suitable for engineering components that require tight fits |
| Inspection Methods | 3D scanning, coordinate measuring machines (CMMs) | Ensures parts meet design specifications |
