Most conversations about 3D printing in surgery focus on a single case: a patient-specific model that helps the team plan one difficult operation. But there is a second, faster-growing use that matters just as much — training. Increasingly, residents and surgical teams learn and rehearse on 3D-printed anatomy before they operate on a real patient, and the 2025–2026 literature suggests this is more than a novelty.

A flat image or a generic plastic trainer can only take a surgeon so far. A patient-faithful physical model — something you can cut, drill, suture, and feel resist your instruments — turns abstract anatomy into reps. And reps, done safely and repeatedly, are how skill is built.

From planning aid to teaching tool

The same property that makes a presurgical model useful for one case — a true-to-scale, patient-specific replica — makes it a strong teaching tool across many trainees. Instead of waiting for a rare case to appear in the OR, a residency program can reproduce that case on demand, hand it to every trainee, and let them rehearse the difficult step as many times as needed.

What the recent evidence shows

Recent studies point in a consistent direction across specialties:

  • Laparoscopy. A 2025 study in Surgical Endoscopy compared VR simulation, 3D-printed organ models, and a combination of both for laparoscopic skills acquisition — part of a broader move to benchmark physical models against purely digital training (Springer, 2025).
  • Neurosurgery. A 3D-printed intraventricular neuroendoscopy simulator used to train residents reported that 91.7% of participants felt more confident about future procedures after training, with gains in visualization and coordination (evaluation + systematic review, 2024).
  • Oral / maxillofacial surgery. A Polyjet-printed simulator for incisions and sutures was evaluated across 27 undergraduates, 19 postgraduates, and 23 expert oral surgeons, supporting its use as a realistic, reproducible training aid (study, 2025).
  • Urology. Combining low-cost, realistic 3D-printed kidney models with personalized video feedback significantly improved dissection precision among residents (study).

No single study settles the question, and several authors note that methods and reporting are still heterogeneous. But the pattern — more confidence, better technical skill, safer first attempts — repeats across very different procedures.

Especially relevant in ORL/ENT and CMF

The case for training simulators is strongest exactly where MedForm3D focuses: ORL/ENT and craniomaxillofacial surgery, where anatomy is compact, three-dimensional, and unforgiving. Temporal bone, sinus, and skull-base work demand spatial intuition that is hard to build on screens alone. Low-cost, reproducible simulators — for example a middle-ear model for ossicular prosthesis placement — let trainees develop that intuition before the stakes are real.

Lower cost and faster than teams expect

A common objection is that patient-specific models are too slow or expensive for routine training. That assumption is aging quickly: in a 2025 randomized hepatobiliary study, AI-enhanced anatomical models were produced in a median of about 3.5 hours at roughly $150 per model — fast and cheap enough to be practical, not just experimental. Turnaround still depends on imaging quality, segmentation complexity, and anatomy, but the direction is clear: high-fidelity models are becoming accessible enough to print for teaching, not only for landmark cases. This sits inside a healthcare 3D-printing market valued around USD 8.5 billion in 2023 and projected to exceed USD 27 billion by 2030, with point-of-care and education among the fastest-moving segments.

Where simulators add the most value

Training simulators tend to pay off most when:

  • the procedure is technically demanding and hard to rehearse otherwise (skull base, temporal bone, neuroendoscopy);
  • trainees need many safe repetitions before live exposure;
  • the anatomy is variable or pathological, so generic trainers fall short;
  • a program wants every resident to practice the same high-difficulty case.

Final thought

Patient-specific 3D printing started as a way to prepare for one operation. It is becoming a way to prepare surgeons. When a team can rehearse the exact anatomy — repeatedly, safely, and affordably — the learning curve moves out of the operating room and into the lab, where mistakes cost nothing.

If you want to bring patient-specific models into your training or your next case, start a project with MedForm3D, or see real models from the workshop.
