Selecting the best 3D printers for dentistry demands a pragmatic approach, factoring in both immediate requirements and future scalability. The total cost of ownership, encompassing material costs, maintenance, and the learning curve associated with new software and workflows, cannot be overlooked. Furthermore, adherence to regulatory standards and validation processes is crucial to ensure patient safety and clinical reliability. A well-defined workflow, combined with proper training and calibration, will maximize the value derived from the selected 3D printer.
Based on the evidence reviewed, a hybrid approach, beginning with a high-resolution resin printer like the Formlabs Form 3B+ for intricate models such as crowns and bridges, and supplementing with an FDM printer for larger surgical guides, is recommended for dental practices with diverse needs and moderate budgets. This combination allows for cost-effective production of both high-precision and bulk applications, maximizing return on investment while ensuring access to a broad range of materials.
