The Process of 3D Printing Dental Models

The process for producing bases for 3D printed dental models is streamlined through modern dental 3D printing technologies, which include:

Digital Scanning: Modern scanning technology provides patients with the comfort of digital processes, which deliver better impression output.

CAD Design: Dental specialists use a CAD software platform to obtain and support scanned data to develop the appropriate models. They are specifically designed and fine-tuned to fit each patient’s specific needs during the manufacturing process.

3D Printing:  After a design process, the object is prepared for 3D printers. The final model is built from several materials via additive build processes. Some of the most common 3D printing technologies used in dentistry are:

• Stereolithography (SLA):  Best for precision and detail.
• Digital Light Processing (DLP): Faster and equally precise as SLA.
• Fused Deposition Modeling (FDM):  Low-cost, ideal for educational prototypes.

After Printing: The printed model is kept to undergo specialized maintenance processes before it can reach the final stage used to undergo curing treatment. Post-print processes create precise clinical applications through model surface topography normalization, strength enhancement, and precision refinement.

Materials Used for 3D Printed Dental Models

Selecting appropriate materials for dental 3D printing plays an essential role in creating precise models that combine robustness with adaptable design requirements alongside their relevance to dental applications to achieve maximum quality outcomes.

• Resins: Dental Resin materials deliver exact production together with adaptable design capabilities to support diagnostic tools that benefit surgical interventions and dental restoration work.
• Plastics: Plastics remain affordable for educational and prototyping models, yet dental resins deliver flexibility when combined with stability and excellent performance in non-medical patient support applications
• Biocompatible Materials: Surgical guides with combined temporary restorations require materials which conform to essential safety parameters for patient health needs.

 Essential characteristics of these materials are:

• Durable: It guarantees long-term use.
• Flexibility: Essential for orthodontic and surgical integration.
• Precision:  It is critical that these materials fulfill the accuracy required during clinical applications.

Cost of 3D Printed Dental Models 

Several factors influence the cost of 3D-printed dental models:

Equipment Costs:

3D Printer Types: The printer’s cost depends on its technology type.

• SLA (Stereolithography) Printers: Liquid crystal and light or stereolithography printers are used within dental model applications where precision requirements exist while their purchase cost varies from $3000 to $50000 based on the selected resolution capabilities.
• DLP (Digital Light Processing) Printers: These range from $2,500 to $40,000.  With superior resolution capabilities, DLP printers outdo SLA printers to quickly create 3D dental model prototypes.
• FDM (Fused Deposition Modeling) Printers: Industrial use applications find FDM printers cost-effective at $200 to $10,000, while these printers fail to meet requirements for dental model precision because of insufficient resolution potential.

Material Costs:

• Resin: You can get dental-grade resins for 3D printed dental models for about $50 per litre; specialized bio-compatible resins for surgical guides can go up to $150 per litre, depending on their durability, accuracy, and biocompatibility.
• Plastic Materials: Typical thermoplastics for societal FDM printers, like PLA and ABS, are priced at $25 to $100 per kilogram but are vastly inferior in precise dental applications compared to resins.
• Specialty Materials: Bio-compatible materials which serve dental surgical guides and models typically run between $200 to $300 per litre according to their specific formulation requirements.

Design Complexity:

• Simple Models: Creating a basic dental diagnostic  3D printed dental model requires $10-$50 materials and takes between 1-3 hours of print time.
• Complex Models: The creation of surgical guides and custom dental prostheses demands complex production protocols, leading to material costs between $50 and $200 while requiring production times extending from 4 to 12 hours or more.

Post-Processing Costs:

The production of new dental products demands careful post-printing tasks, which start with product cleaning followed by curing procedures and possible support structure elimination.

This can add additional costs:

• Cleaning and Curing: Model-based post-processing costs between $5 and $30 per piece according to both dimension and processing needs.
• Labour Costs: Services that include technician time for post-processing usually charge between $15 and $50 per hour.
