Medical 3D-Printed Simulators & Vascular/Heart Phantom Manufacturing Specification: Patient-CT Clear SLA Catheter Flow Phantoms & Heart-sil Surgical Trainers
GLUCK and its dedicated medical simulation brand GLUCK Medical (gluckmedical.com) co-developed the Heart-sil congenital heart surgery training simulator in collaboration with The Hospital for Sick Children (SickKids, Prof. Shi-Joon Yoo’s team) in Toronto, Canada—supplying hospitals across 30+ countries worldwide—and manufacture Seoul National University Hospital anatomical/osteological models, patient-CT (DICOM) optical-clear SLA aortic/neurovascular catheter flow phantoms, and gastrointestinal endoscopy trainers in-house at GLUCK’s 48-machine Paju smart factory.
1. Selecting Between Optical-Clear SLA Vascular Flow Phantoms and Silicone Surgical Simulators (Heart-sil)
Endovascular catheter navigation testing (guidewire torque, stent deployment, PIV flow visualization) and congenital cardiac suturing training demand distinct material physics. Operating 48 large-format industrial SLA systems alongside precision silicone casting cells at a single Paju facility, GLUCK and GLUCK Medical (gluckmedical.com) engineer both rigid optical-clear SLA flow phantoms and tear-resistant multi-durometer silicone organ trainers (Heart-sil series) directly from anonymized patient DICOM data.
| Engineering Dimension | Optical-Clear SLA Vascular & Aortic Flow Phantom | Custom Silicone Cardiac & Organ Trainer (Heart-sil Series) | Primary Clinical & R&D Use Cases |
|---|---|---|---|
| Core Material & Process | Low-yellowing optical-clear SLA resin + progressive wet sanding (400–3,000 grit) + HALS UV clear coat | Precision SLA master/core tooling + multi-Shore-A medical training silicone molding | Endovascular R&D bench testing / cardiothoracic hands-on workshops |
| Lumen & Tissue Fidelity | High optical clarity for real-time catheter tracking, contrast injection, and laser flow imaging | Realistic myocardial, valvular, and vessel-wall incision and suture-retention mechanics | Neurovascular/aortic stent validation / congenital heart repair training |
| Dimensional Accuracy | ±0.15 mm (or ±0.2%) lumen geometry fidelity verified against patient CT/MRI segmentation | 1:1 reproduction of complex pediatric and adult intracardiac septal and valvular defects | Pre-operative surgical rehearsal / global medtech demo kit rollouts |
| Verified Clinical Track Record | Custom neurovascular aneurysm and aortic arch pulsatile-loop phantoms for university hospitals | Heart-sil co-developed with SickKids Toronto (Prof. Shi-Joon Yoo), supplied to 30+ countries; Seoul National University Hospital anatomy models | Repeatable 10–300+ unit clinical training cohorts without hard tooling |
2. Support-Free Tortuous Lumen Engineering, Progressive Optical Polishing & Pulsatile Pump Integration
In 2–4 mm tortuous cerebral and coronary vessel branches, internal support structures would obstruct catheter tips and distort hemodynamic flow. GLUCK’s medical engineering team eliminates internal lumen supports through self-supporting build orientation, followed by pressurized IPA closed-loop flushing, 400–3,000 grit wet sanding, and HALS UV-stabilized optical clear coating.
- Integrated Pulsatile-Loop Ports: Luer-lock, hose-barb, and O-ring flange ports are modeled directly onto aortic inflows and carotid/iliac outflows for leak-free connection to physiological pulsatile pumps.
- Creaform 3D Optical Scan Verification: Critical stenotic and aneurysm geometries are inspected against nominal CAD meshes via 3D color-deviation mapping prior to shipment.
- Moldless 10–500 Set Global Workshop Production: Identical patient-case phantoms for international medtech launches and surgical societies are produced in parallel across 48 industrial SLA machines with 3–5 day DHL/FedEx global delivery (Verified Portfolio Reference · Medical Training Structures Guide · Optical Clear SLA Fluid Manifold & Polishing Guide).
Frequently Asked Engineering & Procurement Questions (FAQ)
Can GLUCK Medical manufacture clear vascular phantoms or cardiac simulators directly from anonymized DICOM CT scans?
Yes. From anonymized patient CT/MRI DICOM files or segmented STL/STEP meshes, GLUCK and GLUCK Medical (gluckmedical.com) engineer wall-thickness offsets, pulsatile-pump fittings, optical-clear SLA catheter flow phantoms, and Heart-sil multi-durometer silicone surgical trainers end-to-end.
How do you prevent internal lumen obstructions and UV yellowing in clear SLA neurovascular and aortic phantoms?
We orient tortuous lumens to print without internal support structures, flush residual resin via pressurized IPA circulation, wet-sand exteriors from 400 to 3,000 grit, and apply a HALS UV-stabilized optical clear coat to maintain catheter visibility and resist yellowing.
What clinical institutions use GLUCK Medical’s 3D-printed surgical simulators and anatomical phantoms?
GLUCK Medical (gluckmedical.com) co-developed the Heart-sil congenital heart surgery simulator with The Hospital for Sick Children (SickKids, Prof. Shi-Joon Yoo’s team) in Toronto, supplying medical institutions in over 30 countries, alongside anatomical/osteological models for Seoul National University Hospital and custom endovascular/endoscopy trainers for global medtech teams.
