We're Transforming Pre-Operative 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 synthetic polymers 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.
Improve Patient Outcomes
Aim for possible time gain, or better margins
Plan for Unique Challenges
Print all complex anatomic cases
Rehearse Without Patient Risk
Perform more than one rehearsal
Limit Costs in Actual Surgery
Improve surgical planning
Laser Focus Your Pre-Operative Care
Rehearsal on a bespoke model allows you to practice complicated procedures while also helping you anticipate unforeseen surgical challenges—all at zero risk to your patients. Empower yourself with the tools to deliver the quality of care your patients deserve.
See It For Yourself

We're Inspired by Innovation

Dr. Jacques Zaneveld, Ph.D.
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.

Demian Kessner, MBA
Director of Educational Products (Skill-Sure)
Demian joined Lazarus 3D after 10+ years of marketing surgical technologies developed by industry leaders Medtronic, Karl Storz Endoscopy, and Boston Scientific. After partnering with Lazarus 3D in previous roles, he is now leading our mission with Skill-Sure to accelerate the learning curve for surgical procedures and inspire new users to operate with confidence.
“Lazarus 3D is unique in that we are FDA-cleared and have patents around the 3D printing process and the materials we use to create the most realistic simulated tissue for surgical training available. Current training options, such as human cadavers or animal tissue models, have their limitations, especially in terms of cost, convenience, and availability. Our customized models can be effective for medical device companies that want to train their field teams and new users, and for surgical residency programs that are interested in speeding up the learning curve for their doctors.”
