Digital Anatomy™ 3D Printer


Cutting-edge realism functional anatomical models.


Cutting-edge realism.

Materials and software combine to create human anatomy that mimics bone and tissue to an unprecedented level of realism.

Animal, cadaver and synthetic models can’t always accurately represent targeted pathology. The J850 Digital Anatomy 3D Printer comes with three unique digital materials and anatomical pre-sets that provide ultra-realistic anatomical simulation and biomechanical realism — resulting in a model that feels and behaves like the real thing. Create the anatomy you need and mimic specific clinical environments for enhanced learning and development.

Bring Medical Models to Life
The J850 Digital Anatomy Printer takes PolyJet™ technology to the next level. Use its capabilities to create models with an incredible array of fine details and minute structures that look, feel and function like actual human tissue, with true haptic feedback. And do all of this in a single print operation with minimal to no finishing steps like painting, sanding or assembly.

Make Model Fabrication Easier
Take the guesswork out of material selection. Choose the anatomy, and the materials are automatically selected for you. You can also adjust the degree of each tissue attribute desired. The gel-like support material can be removed with little or no effort from complex structures, like small blood vessels with internal diameters and wall thicknesses as low as 1.0 mm, making post-processing quick and easy.

Create Complex, Multi-Texture Structures
Combine three new base materials exclusive to the J850 Digital Anatomy Printer to form over 100 unique digital materials. Use the proprietary validated applications offered to mimic human cardiac and vascular anatomy from actual patient scans. Select from a range of anatomical details and tissue properties to integrate into your model. Construct heart models with functional cords, annulus, valves, and calcifications. Vary compliance in vascular models to replicate both healthy and diseased vessels.

Produce Anatomical Models As You Need Them
The J850 Digital Anatomy printer lets you maintain a digital inventory and print models on demand when you need them.

Achieve Efficiency Gains
Because the J850 Digital Anatomy printer allows you to produce anatomies that feel and behave like the real thing, it reduces the necessity for animal and cadaver labs allowing you to test and train anywhere. That means a reduction in training and procurement costs. It also means improved ethical practice, because it minimizes the use of animals for device testing and surgical training.



The versatility of the Stratasys J850 stems from its high material capacity. By blending up to six materials in specific concentrations and microstructures, right on the build tray, it yields hundreds of thousands of colours, translucencies and durometers.

Full colour gamut:

Blending Rigid Opaque materials, you can 3D print in over 360,000 colours for unmatched realism.


Add Rubber-like materials for a range of bright and subtle colours, opacities and elastomer characteristics.


Incorporate transparent materials to vary tint and opacity.

Strength and durability:

Simulate standard ABS plastic to produce durable tools and prototypes that are tough and heat resistant. Combine with Rubber-like material for outstanding durability and a range of Shore A values.
