Stratasys J850 Core 3D Printer
Stratasys PolyJet 3D Printers
The Stratasys J850 Core is a professional PolyJet 3D printer designed to make multi-material functional prototyping more accessible for engineering teams. It offers core performance – such as producing accurate, realistic prototypes for form, fit, and functional validation – without the full-colour capabilities and higher costs of premium models. This printer provides a balance of versatility, functionality, and affordability, helping teams streamline their product development cycles.
Features and Benefits
Three-Material Printing: Allows combining rigid, flexible, and transparent materials in a single part, ideal for creating overmoulding, seals, snap fits, and transparent elements.
- Large Build Volume: A 490 x 390 x 200 mm tray supports large parts or batch production, boosting throughput.
- Fast Print Modes: Includes High Quality and High Speed modes to accelerate turnaround times and increase productivity.
- Simplified Workflow: Uses GrabCAD Print Pro software with automatic nesting, layout optimization, and job presets, reducing manual preparation and post-processing.
- Cost Efficiency: Offers a more affordable entry into professional PolyJet printing for teams that need core performance without unnecessary complexity.
Typical Applications
- Functional Prototyping: Validate form, fit, function, and assembly with durable, multi-material parts.
- Consumer Product Development: Rapidly iterate on housings, enclosures, wearables, and other refined product designs.
- Automotive Prototyping: Produce durable components, flexible seals, and interior prototypes for design and engineering validation.
- Medical Device Prototyping: Create complex instruments, housings, and multi-textured models for evaluation before committing to tooling.
The Core Advantage of PolyJet Technology
PolyJet 3D printers remove the constraints of traditional modelling methods for designers, engineers, educators, and healthcare professionals. The technology uses curable liquid photopolymers to deposit ultra-fine layers, producing smooth surfaces, intricate details, and vibrant colours. Stratasys® PolyJet can bring ideas to life across virtually any colour spectrum, combining translucency, opacity, rigidity, and elasticity while simulating numerous desired materials and finishes.
Versatility and Accessibility
The flexibility of PolyJet stems from its wide range of material properties and a suite of printers to fit different budgets and applications. Regardless of the industry, this technology enables users to refine ideas quickly and accurately.
Key Benefits by Field
- Product Design: Helps designers save 50% of their time by creating realistic prototypes, models, and functional parts – complete with full-colour elements, labels, and true-to-life textures – in a single print job.
- Healthcare: Full-colour, flexible materials produce lifelike anatomical models for physician training and pre-surgical planning, lowering operating room costs and improving patient outcomes.
- Education: Allows students to design, test, and discover in days instead of weeks.
- Dental Labs: Increases efficiency by printing large quantities of varied dental parts with different materials together in one unattended job, reducing labour while significantly scaling capacity.
PolyJet Compatible Materials
The Stratasys J850 Core supports essential PolyJet materials for realistic functional prototypes:
- Tough Materials: Engineering-focused resins (black and white) for durable, high-performance functional parts.
- Rigid Materials: High-quality resins for accurate concept models, housings, and smooth-finish parts.
- Transparent Materials: For lenses, covers, fluid visualization, and clear part validation.
- Flexible Materials: For gaskets, grips, soft-touch features, seals, and overmoulding applications.
- Support Material: Uses SUP705B™ for easy removal during post-processing.
