Medical 3D Printing: Custom Implants, Surgical Guides and Training Models

Additive manufacturing has become a transformative technology in medical device development and surgical planning. Its ability to produce patient-specific geometries from biocompatible materials is opening new frontiers in personalised medicine.

Patient-Specific Surgical Guides

Surgical guides printed from a patient’s CT scan data allow surgeons to rehearse complex procedures and position implants with sub-millimetre accuracy. Aminish produces medical-grade guides in biocompatible resins that are sterilisable and cleared for intraoperative use.

Custom Implants via DMLS

Direct Metal Laser Sintering (DMLS) in Ti-6Al-4V and CoCr alloys enables patient-matched orthopaedic implants and dental prosthetics. The porous lattice structures achievable only with additive manufacturing promote osseointegration — far better than traditional smooth-surface implants.

Training and Anatomical Models

High-fidelity SLA models of patient anatomy give surgeons a tangible rehearsal tool before the operating theatre. Our anatomical models help medical schools train the next generation of surgeons on patient-specific cases.
