Cardiovascular Models

3D Systems’ anatomical models are the ultimate tool for visualization of complex cardiovascular anatomy. Service begins with the receipt of patient imaging data from CT or MR scans followed by image processing and model design resulting in a 3D printed patient specific model.

These models can be made from a variety of materials:

    Full-color CJP (Color Jet Printing) models allow for color identification of anatomical structures. MJP (Multi-Jet Printing) models are highly accurate and can be printed using multiple materials including flexible material which is ideal for pre-surgical rehearsal. CJP and MJP are optimal for use prior to surgery for planning and patient education. Translucent SLA (Stereolithography) models can be uniquely enhanced with selective pigmentation to highlight vital structures. These models can be steam sterilized for reference during surgical procedures.

Patient Specific Anatomical Models

3D Systems has been instrumental in establishing this industry segment, which focuses on taking medical images from the computer screen to the 3D world. Different additive manufacturing processes and materials are used to produce physical anatomical models used in surgeries such as reconstruction of the cranium and the hip.

Applications for Anatomical Models

    Craniofacial Reconstruction:
      Cases for reconstruction of congenital disease in pediatric patients have been a good indication for the use of models. Procedures such as cranial vault remodeling, resection/reconstruction of fibrous dysplasia and mid-face advancement all benefit from the use of a model preoperatively for surgical time savings and enhancement of outcomes.
    Cranio-Maxillofacial Distraction Osteogenesis:
      Use of a model in planning distraction osteogenesis procedures has proven to help answer questions relating to the type of distraction device used, the size of the device and intraoral versus external device type. Additionally, the model can save operating time by allowing precise pre-bending before surgery, taking into account the vectors of distraction and vital structures such as teeth buds and the inferior alveolar nerve.
    Mandibular/Maxillofacial Reconstruction:
      Cases of reconstruction following trauma or congenital disease can be planned using models. Issues such as symmetry, projection and volume can be better visualized using a model. Implants and reconstruction plates can be pre-bent before surgery, allowing for a better contour and shorter surgical time.
    TMJ Reconstruction:
      Three-dimensional analysis of the temporomandibular joint using anatomical modeling has proven an invaluable aid for surgeons treating TMJ. For cases of severe joint degeneration, stereolithography models can be used for creation of custom total joint replacement components.
    Spinal Fracture and Degenerative Disease:
      Assessment of the facet joints can be visualized and intervertebral measurements can be accurately accomplished using the model preoperatively. Surgical techniques and determination of osteotomy placement can be visualized and planned using models.
    Patient-Specific Complex Cardiac and Vascular Anatomy:
      Models are suitable for use as pre-surgical planning tools, educational resources and benchtop fixtures for testing of instruments and implants.

ArthroView Anatomical Models®

3D Systems offers its ArthroView Anatomical Models® exclusively for orthopedic applications. These opaque-white stereolithography models are the ideal visualization tool for orthopedic reconstruction and oncologic cases. Highly accurate and sterilizable, these models provide a true three-dimensional view of complex anatomy and allow for hands-on surgical planning. Following the medical imaging step, which reconstructs the two-dimensional images into three-dimensional files, the bone model files are sent to our fleet of state-of-the-art stereolithography additive manufacturing machines. These machines typically produce single or multiple models over many hours, in a layered, additive fashion. Models are made in a biocompatible resin, which is UV-cured layer by layer by an ultraviolet laser. Once complete, the models are sent through our intensive quality control system and readied for shipment to the surgeon. ArthroView models can be sterilized, if needed, for reference in the sterile field during the surgical procedure. Typical turnaround can be from one to two weeks with faster turnaround possible for urgent needs.

    Orthopedic Applications of ArthroView Anatomical Models®
      Acetabular Fractures:
        Providing a disarticulated model of the acetabulum and proximal femur provides a method for assessing the joint. Examination of true 3D data will enhance the decision-making process and help with surgical treatment options, including sizing of off-the-shelf implants or fabrication of custom-made acetabular components.
      Calcaneal Fractures:
        Three-dimensional analyses of the calcaneous offers a direct hands-on approach in determining the need for surgery. Disarticulation of the subtalar joint allows for clear visualization of complex fractures.
      Tibial Plateau Degeneration/Fractures:
        Using a model to evaluate treatment options for complex tibial plateau fractures allows for better visualization than traditional imaging techniques.
      Spinal Fracture and Degenerative Disease:
        Assessment of the facet joints can be visualized and intervertebral measurements can be accurately accomplished using the model preoperatively. Surgical techniques and determination of osteotomy placement can be visualized and planned using models.

OsteoView Anatomical Models®

3D Systems' OsteoView modeling line was conceived to provide a lesser-expensive alternative to the gold-standard ClearView™ modeling line. These highly accurate models of bony anatomy begin with expert image processing of the CT/CBCT input data. Following segmentation, the three-dimensional files of the bone structure are sent to a Color Jet printer, utilizing inkjet printing technology developed at Massachusetts Institute of Technology. Layers of powder are bound together, forming the model in a layered fashion over the course of several hours. Following production, the models are quality control checked for accuracy before being prepared for shipment to the surgeon. These models are opaque white in look and are not meant to be used inside the sterile field; their use is limited to non-sterile use. Typical turnaround can be from one to two weeks with faster turnaround times possible.

ClearView Anatomical Models®

3D Systems' premier offering for custom anatomical models are its ClearView Anatomical Models®. These highly accurate models of bony anatomy begin with expert image processing of the CT/CBCT input data. ClearView models are translucent and have a unique ability for selective coloration whereby the model can contain a deep red coloration to highlight vital structures such as tumors, vascular structures or tooth roots. Following the medical imaging step, which reconstructs the two-dimensional images into three-dimensional files, these files are sent to our fleet of state-of-the-art stereolithography additive manufacturing machines. These machines typically produce single or multiple models over many hours, in a layered, additive fashion. Models are made in a biocompatible resin, which is UV-cured layer by layer by an ultraviolet laser. Once complete, the models are sent through our intensive quality control system and readied for shipment to the surgeon. ClearView models can be sterilized, if needed, for reference in the sterile field during the surgical procedure. Typical turnaround can be from one to two weeks with faster turnaround possible for urgent needs.
