Stratasys J850 Digital Anatomy

The Stratasys J850 Digital Anatomy 3D printer truly brings the look and feel of medical models to life with unrivaled accuracy, realism and functionality

Unmatched realism

The Stratasys J850 Digital Anatomy Printer brings medical models to life with incredible realism that accurately represents both the appearance and response of human tissue.

Whether for surgeon training or testing new medical devices, these models provide unmatched clinical versatility and reduce the costs and inconveniences of cadaver and animal labs.

Stratasys J850 Digital Anatomy Features

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.

On-demand Models

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.

Complex, Multi-Texture Structures

Combine three new base materials exclusive to the J750 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.

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.

Stratasys J850 Digital Anatomy Benefits

Visual medical model

For Medical Demonstration

This heart model printed with rigid Vero™ materials highlights the J750 Digital Anatomy Printer’s ability to produce anatomical models with fine details using multiple colors and materials, texture gradients, transparencies and durometers.

Functional medical model

For Surgeon Training and Device Testing

This heart model features functioning cords, annulus, and valves with leaflets, created with the J750 Digital Anatomy Printer’s cardiac application. It combines the ultra-soft TissueMatrix™ material with Agilus30™ to mimic the feel and response of myocardium, giving realistic haptic feedback during device insertion and deployment.

Liver model

More Versatility

Take advantage of the versatility offered by the J750 Digital Anatomy Printer. Use the 100+ anatomical presets or when full color capabilities are desired over biomechanical properties, select from over 500,000 colours. Define transparencies. Determine textures and finishes. Create an end product that’s as close to the real thing as possible.

With PolyJet technology and multi-material capabilities built-in, you can 3D print prototypes or anatomical models in the most intricate detail.

Medical procedure trial

Feel the difference

Animal, cadaver and synthetic models can’t always accurately represent targeted pathology. 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.

Materials available for the Stratasys J850 Digital Anatomy

Gelmatrix material

GelMatrix™ resin

A gel-like support material for easy removal from blood vessels. Inner diameter as small as 1mm and wall thickness as low as 1.5mm.

Tissuematrix material

TissueMatrix™ resin

The softest translucent material commercially available. Ideal for replicating the look and feel of heart tissue.

Radiomatrix material

RadioMatrix ™

Print radiopaque medical models that exhibit radio-realistic properties under X-Ray and CT. Control the HU values to achieve specific contrast levels to mimic different anatomies.

Bonematrix resin

BoneMatrix™ resin

Create complex material depositing patterns that mimic porous bone structures, fibrotic tissues, and ligaments, providing the most realistic feedback when cutting and drilling.

Advantages of PolyJet Technology

Advantages of parts built with a Stratasys PolyJet Machine

Realistic Parts

Stratasys PolyJet 3D Printers are based on proven technology, which creates precise prototypes that set  the standard for finished-product realism.

Their fine resolution makes complex shapes, intricate details  and smooth surfaces possible.

Precise Models

PolyJet 3D Printing works by jetting layers of liquid photopolymer onto a build tray and instantly curing them with UV light.

The fine layers build up to create a precise 3D model or prototype. Models are ready to handle right out of the 3D printer, with no post-curing needed.

Better ideas, easier sell

PolyJet 3D printed models improve communication and collaboration because they produce amazingly  accurate representations of your ideas that you can share with your team and your clients for a faster, more confident buy-in.
