Custom Titanium 3D Printing: Rapid Prototyping And Production for Dental Needs
Introduction
Custom titanium 3D printing offers precise, efficient solutions for the dental industry, enabling rapid prototyping and production of crowns, bridges, and implants. Utilizing advanced techniques such as Selective Laser Melting (SLM) and Direct Metal Laser Sintering (DMLS), medical-grade titanium alloys like Ti-6Al-4V ELI (Grade 23) enable high-strength, corrosion-resistant, and biocompatible dental devices.
Compared to traditional casting or milling, custom titanium 3D printing accelerates production by up to 60%, achieves superior accuracy (±0.03 mm), and allows the fabrication of highly personalized dental solutions.
