Practice Perfection.

Improve patient outcomes by rehearsing surgeries on realistic, 3D-printed models.

We're transforming preoperative care.

Each patient is unique, we strive to establish personalized medicine solutions for patients and physicians alike. Our Pre-Sure® (PRE-operative SUrgical REhearsal) models are made with soft silicones and hydrogels that mimic human tissue making them ideal for practicing incisions and sutures. They allow you to practice on a 3D printed, patient-specific replica before operating. Personalized patient care improves patient experience, maximizes safety and drives better outcomes.

Dr. Jacques Zaneveld

Founder & CEO

Dr. Jacques Zaneveld is a professional scientist and entrepreneur. Half of his early life was spent on a boat in the South Pacific, while the other half was spent in Corvallis, Oregon. Traveling the world instilled him with a sense of wonder and curiosity that fuels his work to this day.

Trained as a scientist, Dr. Jacques Zaneveld has published numerous scientific papers, and obtained funding for his work from the National Eye Institute, National Library of Medicine, the CIBR center, and the National Science Foundation. Originally, 3D printing was a hobby, but he quickly realized its potential to revolutionize medicine and science.

Jacques founded Lazarus 3D to help scientists and clinicians by providing them with 3D printing tools and techniques.

Dr. Smriti Zaneveld, PH.D.

President and Founder

Dr. Smriti Zaneveld joined Lazarus 3D in 2018 and serves as President. Prior to joining Lazarus 3D, Dr. Smriti Zaneveld completed her Ph.D. at Baylor College of Medicine where her research focused on identifying the genetic causes of inherited eye diseases, and developed novel therapeutic treatments for ocular disorders.

She has a proven track record as a successful scientist with over a dozen scientific publications in the areas of human genetics and 3D printing, and adds valuable depth to Lazarus 3D's team. She has also mentored numerous trainees, presented at many international scientific/medical conferences, and has served as a reviewer for scientific peer-reviewed journals.

Smriti is very passionate about the development of innovative technologies in medicine using 3D printing that can improve patient care and surgery outcomes.
