What Is PolyJet 3D Printing Technology?

PolyJet is an advanced photopolymer 3D printing technology that jets tiny droplets of liquid photopolymer resin onto a build platform, then cures each layer instantly with UV light. Unlike traditional 3D printing technologies, PolyJet stands out for its ability to print multiple materials and colors in a single print job—it can combine rigid, flexible, transparent, and opaque resins, as well as gradient colors, to create parts that mimic the look and feel of real-world products.

EPTAHUB has invested in industrial-grade PolyJet printers (such as Stratasys J850, Objet500 Connex3), which feature ultra-fine print heads with droplet sizes as small as 16 microns (comparable to the diameter of a human hair). The minimum layer thickness can reach 16 microns, and the positioning accuracy is ±0.1mm, ensuring exceptional detail reproduction. Whether for multi-material functional prototypes, colorful consumer product models, or medical simulation parts, EPTAHUB’s PolyJet 3D printing service delivers unmatched realism, making it ideal for industries like consumer electronics, medical device development, automotive design, and toy manufacturing.

EPTAHUB PolyJet 3D Printing Advantages

Compared to other 3D printing technologies, EPTAHUB’s PolyJet service offers unique benefits that make it a top choice for high-fidelity and multi-material applications:

Multi-Material & Multi-Color Printing In One Job

PolyJet can combine up to 14 different materials (or 600,000 color combinations) in a single print, eliminating the need for post-assembly. For example, EPTAHUB printed a smartphone case prototype that integrated a rigid outer shell (VeroWhitePlus), a soft grip (TangoBlackPlus), and a transparent window (VeroClear) - all in one print run - saving the customer 80% of assembly time.

Ultra-High Detail & Realistic Texture

With droplet sizes as small as 16 microns, PolyJet captures tiny features like fine textures, logos, and even micro-engravings (down to 0.1mm). Parts have a smooth, finished surface right off the printer (Ra 1.0-2.0μm), requiring minimal post-processing - perfect for consumer product appearance models and medical simulation parts.

Fast Molding Speed And Short Delivery Cycle

EPTAHUB's industrial-grade PolyJet printers have high-speed jetting and instant UV curing capabilities. A single small part (such as 50×50×50mm) can be printed in as fast as 2 hours; the delivery cycle for regular orders is 2-5 days, and urgent orders can be delivered in as fast as 1 day, greatly shortening the product design verification and launch cycle.

PolyJet 3D Printing Design Guidelines

Dimensional Considerations & Tolerances

Minimum part size: Length/width ≥ 0.3mm, height ≥ 0.2mm; micro-features (e.g., thin walls, small holes) ≥ 0.1mm;
Standard tolerances: ±0.05mm (parts ≤ 50mm), ±0.1mm (parts 50-100mm), ±0.15% (parts ＞ 100mm);
Overhangs: Unsupported overhangs up to 5mm are possible without supports; for overhangs ＞ 5mm, add minimal supports (1-2mm diameter) to prevent sagging.

Wall Thickness & Structure

Minimum wall thickness: 0.2mm for rigid resins (e.g., VeroWhitePlus), 0.3mm for flexible resins (e.g., TangoBlackPlus);

Wall thickness uniformity: Avoid sudden thickness changes (＞ 2mm) to prevent curing unevenness;

maintain consistent thickness (±0.1mm) for best dimensional stability;
Hollow structures: For large parts, use hollow designs with 1-2mm wall thickness to reduce weight and material usage; add 1-2mm vent holes to allow resin flow during printing.

Material Combination & Color Design

Material compatibility: Ensure combined materials have similar curing properties (consult EPTAHUB’s material guide for compatible pairs);

Avoid combining rigid and ultra-soft resins in areas with high stress;

Color design: Use RGB color values for precise color matching;

For gradient colors, allow a 1-2mm transition zone between colors to ensure smooth blending;

Texture application: Apply textures (e.g., matte, glossy, grainy) directly in the 3D model;

EPTAHUB’s software supports high-resolution texture mapping for realistic results.

Post-Processing Recommendations

Support removal: Use EPTAHUB’s specialized tools to remove supports; for delicate parts, use ultrasonic cleaning (5-10 minutes) to remove residual resin;
Polishing: For transparent resins (e.g., VeroClear), polish with 800-2000 grit sandpaper followed by polishing compound to achieve a glass-like finish;
Sterilization: For medical parts (e.g., MED610 resin), use ethylene oxide (EO) sterilization or UV light sterilization—avoid high-temperature sterilization (＞ 60°C) to prevent material degradation.
