This large, white tooth model is a custom high-precision dental model or enlarged anatomical model manufactured by RPS for dental clinics, medical schools, or equipment manufacturers. In the medical and dental fields, the requirements for geometric accuracy, surface smoothness, and detail fidelity are crucial, as they directly impact diagnostic outcomes and surgical success.

RPS utilizes SLA (Stereolithography) technology with a highly detailed medical-grade resin to successfully manufacture models featuring a smooth surface, clear root structure, and precise hole positions (for potential cavities or nerve channels). These models are widely used for teaching, patient communication, and surgical rehearsal.

Client Challenges: High-Fidelity Detail, Surface Quality, and Biocompatibility

Dental and medical models face the following core challenges in design and manufacturing:

1. Sub-Millimeter Anatomical Detail Fidelity: Models must accurately capture the fine anatomical features of the tooth, such as cusps, fissures, and root canals, for precise diagnosis or the creation of surgical guides.
2. Surface Smoothness: SLA-printed models have a smooth surface, which facilitates cleaning and sterilization, and provides a realistic tactile feel for teaching or patient communication.
3. Material Safety and Stability: Medical and dental prototypes require materials to possess biocompatibility and long-term dimensional stability to ensure the accuracy of testing and planning results.

RPS Solution: SLA Precision Printing and Medical-Grade Post-Processing

To meet the strict requirements for high detail and safety in dental applications, RPS provided the following SLA additive manufacturing solution:

1. Core Process: SLA (Stereolithography) 3D Printing

• Technological Advantage: SLA printing boasts the highest precision and smoothest surface finish among all 3D printing technologies, allowing for the perfect replication of the tooth model's complex curved surfaces and fine structures.
• Material Application: Utilizing Medical/Dental Grade Resin.
  • Advantage: These resins are typically ISO or FDA certified, ensuring biocompatibility, making them suitable for auxiliary models or guide prototypes that contact the skin or mouth.

2. Precision Assurance and Detail Fidelity

• Tolerance Control: Dental models often require tolerances of $pm 0.05 text$ or even higher. RPS achieves high-dimensional accuracy by optimizing the resin formulation and the photo-curing process.
• Anatomical Feature Highlight: The model clearly displays the tooth's multi-root structure and crown morphology, making it easier for doctors and students to observe.

3. Surface Finish

• Smooth Surface: After SLA printing, the parts undergo professional cleaning and post-curing with UV light to ensure the model surface is smooth and non-porous, meeting the usage requirements for medical models.
