3D printing in medicine is revolutionizing healthcare by enabling patient-specific solutions.
Titanium implants, precise surgical instruments, and medical devices such as hearing aids can now be individually manufactured using metal 3D printing technologies like SLM (Selective Laser Melting). These innovations improve treatment outcomes and make surgical procedures more efficient.
With advanced metal 3D printers such as the 2Create and 2Create Plus, users can achieve maximum flexibility and precision.
Watch the complete manufacturing process of 3D-printed titanium hearing aids.
Titanium Implants per 3D Printing
Titanium implants are biocompatible, lightweight, and extremely strong – ideal for bones and joints. Thanks to 3D printing in medicine, implants can be precisely manufactured for the skull, jaw, spine, or joints, allowing for optimal anatomical customization.

Benefits for Patients
- Patient-specific: Perfect anatomical fit
- Faster recovery: Quicker healing and fewer complications
- Shorter surgery times: Implants can be inserted directly, with minimal adjustments needed during the operation
Titanium Implant Components
Metal 3D printing also enables the production of individual implant components, including:
- Joint balls for hip or shoulder joints
- Screws, plates, and connectors
- Adapters for prostheses that require complex geometries or customization
Optimized Implant Surfaces
- Porous lattice structures: Fine, mesh-like structures in the implant allow bone cells to grow in, improving fixation within the bone.
- Surface treatment: Specialized surface textures increase the implant’s durability and stability.
Titanium Medical Devices
3D printing in medicine also demonstrates its strengths for medical devices: a particularly innovative example is hearing aids made entirely from titanium, produced with the 2Create metal 3D printer.
Benefits for Patients and Manufacturers
- Titanium: lightweight, durable, biocompatible
- Complex, intricate shapes possible
- Maximum fit and comfort
- Faster production, minimal post-processing, precise mechanics
In addition to hearing aids, experimental titanium components are being tested, such as cochlear implant housings or parts for infusion pumps. They are lightweight, durable, and customizable, but not yet standardized.
Patient-Specific Surgical Instruments
For surgeries, specialized instruments can be 3D-printed from titanium or stainless steel to fit individual patients. Examples include:
- Drill guides or templates for dental or bone surgeries
- Endoscopy and microsurgery instruments with fine, complex structures
These instruments provide precise guidance, enhance safety, and are often used as single-use products.
Conclusion – 3D Printing in Medicine
3D printing in medicine demonstrates how implants, medical devices, and surgical instruments can be manufactured efficiently, precisely, and individually.
Metal 3D printing processes like SLM enable customized treatment solutions, improved outcomes, higher quality, and more efficient surgeries – an important step toward personalized medicine.
