Digital Anatomy
Materials: GelMatrix®
In order to enrich the medical modeling field and enable thecreation of more realistic anatomical models, Stratasys hasdeveloped a new series of Digital Anatomy™ Materials.
This information includes a collection of materials that can beused to mimic human tissue.
Mixing these materials in different ratios, along with PolyJet™
materials such as the Vero™ family and Agilus30™, can generate
a range of shore values to create almost any anatomy in thehuman body. This family of materials opens new possibilities toenrich medical modeling — to create models with mechanicalproperties similar to any type of tissue, educate, suture,puncture, drill, stretch and perform mechanical tests for research
and medical practice.

GelMatrix
The watery translucent material GelMatrix is used to mimic soft and damp
tissues and as an easy-to-remove support material for small cavities like inblood vessels for instance. This material cannot be printed as pure material
due to its softness and instability; it should be mixed with other, more stablematerials such as Agilus30. Example anatomy presets include:• Liver				• Subcutaneous Fat		• Gel Support• Pure Gel Support

To ensure proper curing while printing a preset that contains GelMatrix, use
only one UV lamp in the curing process of each layer. Using two UV lamps
can cause the edges of the model to burn. Due to its unstable properties,
this material does not have consistent mechanical properties.

Collaborations Make Development
Stratasys has collaborated with the top research and medical institutes todevelop a library of anatomies that can be printed for research, surgicalplanning and education using the Digital Anatomy printer and PolyJet materials.
Medtronic
Scientists and engineers from global leader in medical device manufacturing,
Medtronic, performed a series of tests to compare the compliance ofStratasys Myocardium and Liver presets to porcine tissues. The results
showed a remarkable compatibility between the two. For more information,
read the white paper “PolyJet 3D Printing of Tissue Mimicking Materials:
An Investigation of Characteristic Properties of 3D Printed Synthetic Tissue.”
Jacobs Institute
The Jacobs Institute, a medical innovation center that focuses on vascular
medicine, reviewed the use of 3D printed models for pre-surgical planning.
They used a Stratasys 3D printed neurovascular model for pre-surgicalplanning of aneurysm surgeries. The compliance and realism of the printed
model and its materials gave the surgeons the opportunity to prepare properlyfor the procedure. In 2020, these scientists performed an extensive set ofexperiments to explore the accuracy of Digital Anatomy materials and vascularpresets, and the results were remarkable.

a direct characterization of model distensibility using intravascular ultrasound.”© 2022 Stratasys Ltd. All rights reserved. Stratasys, Stratasys signet, Agilus30, GelMatrix, Digital Anatomy, PolyJet and Vero are trademarks
