3D Prototype & Fabrication Service

The Radiation Oncology 3D Service accelerates the development and manufacture of patient-optimized treatment devices and custom components for basic and translational research.

Our in-house 3D device design and manufacturing service is driving innovation in the clinic and laboratories. While digital 3D modeling accelerates prototype development, stereolithographic (SLA) printing with medically-approved resins produces high-quality, patient-specific devices on-demand. 

Examples of current projects include:

  • Medical procedure devices (i.e., brachytherapy applicators, boluses, lung blocks)
  • Quality assessment tools (i.e., geometric and dosimetric phantoms, ISO limits)
  • Specialty laboratory apparatus

Each component is manufactured with resins optimized for its specific application. With rapid 3D prototyping, the path from inspiration to application has never been shorter!

Examples of Clinical Devices

GYN brachy components
GYN Brachytherapy implant device: Patient-specific interstitial cylinder and plate for gynecological brachytherapy procedure (in-situ for up to 60 hours). Printed with biomedical resin approved for steam sterilization and extended contact with skin and mucosal membranes.
Vaginectomy plate
Vaginectomy needle guide: Custom-sized plate printed with approved biomedical resin for vaginectomy procedure.
Phantom spheres
Phantoms for precision treatment calibration: 3D spherical array.
Lung block
Radiation beam blockers: Tissue-sparing lung block prototype customized for each patient from DICOM data. Blocks are filled with reusable metal bearings.

Examples of Laboratory Devices

Kidney phantom
Simulated organs for translational research: Images of the 3D printed kidney phantom (printed in two halves and glued together) with separately fillable cortex and medulla, and modeled from a DICOM image from the patient. The medulla was filled at 1/3 rd the cortex Lu-177 activity concentration to mimic what is believed to occur in patients undergoing Lu-177 DOTTATE therapy.
Transducer
Phantoms for research: Transducer model to take ultrasound images concurrent with radiation therapy.
Orthovoltage corner support
Specialty laboratory equipment: Corner supports to suspend a polycarbonate shield beneath the Orthovoltage unit.
