Ultra-Realistic Anatomical Simulation 3D Printing
3D Printers from GoEngineer are Available in the U.S.  Now Serving US & Canada  3D Printers from GoEngineer are Now Available in Canada


The relevance of 3D printing to the medical industry is fundamentally changing with the arrival of the Stratasys J850 Digital Anatomy Printer. Stratasys’ mission for the J850 DAP is to replicate the biomechanical properties of cardiac, vasculature, and bone in addition to general anatomies such as tumors, fibrotic tissue, soft or elastic organs, and more. With a shift away from printing “parts” to instead printing “anatomies,” the J850 DAP offers something medical professionals worldwide have dreamed of: on-demand, ultra-realistic anatomical simulation models.

These models give us the best opportunity to re-create human physiologic conditions on a structural basis to simulate clinical situations and study new devices to establish their effectiveness before introducing them into patients.

  Learn how to reduce costs by up to 70% with the Stratasys J850 Digital Anatomy Printer
When compared to synthetic and biological models (e.g., cadavers and animals)

Because the J850 Digital Anatomy 3D Printer allows you to produce anatomies that feel and behave like the real thing, it reduces the necessity for the use of synthetic models, animals, 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 eliminates the need to test surgical procedures and devices on animal subjects.





Heart Valve printed on the Stratasys J850 DAP


Bone and tissue are exceptionally intricate in their makeup – their multi-material, variable density, regional internal structures heavily influence their mechanical properties. An ultra-realistic model will need to replicate the interior structures of the anatomy – treat femurs differently than skulls – and the J850 DAP does that.

Voxel Printing

The hardware is important – the ability to print six materials simultaneously (and  water-soluble support) is a pre-requisite to creating hyper-realistic anatomical models. But an easy-to-use software, with drop-down menus for 100+ anatomical presets, is what empowers the everyday user to take advantage of the J850 DAP. Complex internal structures and regions are built at the voxel level automatically by GrabCAD Print. Only a few clicks are required to print calcified blood vessels or cardiac blood clots – no medical experience necessary.

Stratasys J750 Digital Anatomy 3D Printer Matrix Materials

Matrix Materials

New materials, developed specifically to match anatomical requirements, help make this solution reality. TissueMatrix, BoneMatrix, RadioMatrix, and GelMatrix are combined during the print process in the same way a desktop printer combines CYMK ink to achieve hundreds of thousands of colors (which, by the way, the J850 can also do!). Think of it this way: instead of loading CMYK inks you are loading flesh, fat. bone, connective tissue, skin and the printer is outputting ultra-realistic anatomical models.

Frequently Asked Questions

Source files can be obtained from imaging data (X-ray, CT, MRI, EKG, etc) or engineered models. Imaging files, such as DICOM, may require some segmentation before loading into the GrabCAD Print software. Once the outside shape is loaded into GrabCAD Print, the operators control the inside structure through a series of drop-down menus. Simple!
Great question – you may be in the vascular field if you are concerned about clearing long, winding, narrow passages of support material. Stratasys developed GelMatrix material and the new Blood Vessel Cleaning Station to make this process possible. The cleaning station is sized to handle 2 full size TAVR/Neuro models at a time and provides an unattended cleaning experience.

The mission to recreate anatomy could be viewed as daunting – there are countless combinations of variables. But the implications of such an ability are an enormous good for the medical industry and Stratasys is committed to accomplishing that goal. Extensive R&D and industry partnerships will bring new materials, new anatomies, and new pathologies to the J850 DAP platform for years to come.
