Metal 3D printer J850™ Core

plasticPolyJethigh-speed

Overview
J850™ Core makes professional PolyJet 3D printing more accessible for engineering teams and prototyping labs that need fast, accurate, multi-material prototypes without full-color capability. Built for versatility, functionality, and affordability, it enables realistic multi-material prototypes that support form, fit, and functional validation.

Key Features

• Three-material printing: combine multiple materials in one part for overmolding, seals, snap fits, and transparent elements.
• Large build tray: 490 x 390 x 200 mm build volume supports large parts or efficient batch production.
• Fast print modes: includes High Quality and High Speed print modes for quick turnaround and higher throughput.
• GrabCAD Print Pro workflow: automatic nesting, layout optimization, and job presets to streamline print preparation.
• Material versatility: supports rigid, flexible, transparent, and tough engineering materials, including ToughONE™-compatible materials.

Benefits

• More accessible professional PolyJet capabilities focused on core engineering needs rather than full-color complexity.
• Functional prototypes with rigid, flexible, transparent, and tough materials in the same print.
• Faster iteration cycles supported by high-speed modes and large tray capacity.
• Simplified, office-friendly workflow with minimal post-processing and GrabCAD Print Pro support.
• Competitive pricing and cost efficiency while maintaining core PolyJet capabilities and high throughput.

Typical Applications

• Functional prototyping: validate form, fit, function, and assembly with accurate multi-material parts.
• Consumer product development: rapid iteration for housings, enclosures, wearables and refined product concepts.
• Automotive prototyping: durable components, flexible seals, and interior prototypes for engineering validation.
• Medical device prototyping: complex instruments, housings, and multi-textured prototypes for evaluation before tooling.

Materials
Supports essential PolyJet materials for realistic functional prototyping, including PolyJet ToughONE™, VeroUltra™, VeroUltra™Clear, Agilus30™ and other rigid, flexible and transparent resins suitable for engineering prototypes.
