Background:

• Laser lithography is a widely used medical rapid prototyping method.
• Binder jetting offers potential advantages over traditional methods.
• Computed tomographic (CT) data is crucial for creating patient-specific models.

Purpose of the Study:

• To evaluate the accuracy and feasibility of the binder jet method for creating full-scale medical models from CT data.
• To compare the binder jet method with the established laser lithography technique.
• To assess the suitability of binder jetting for craniomaxillofacial surgery applications.

Main Methods:

• Utilized a dry skull for comparative analysis of rapid prototyping techniques.
• Employed data from a multidetector helical volume scan computed tomography device.
• Produced full-scale models using both binder jet and laser lithography methods.

Main Results:

• Binder jet method demonstrated accuracy comparable to laser lithography.
• The technique proved satisfactory in terms of speed, cost, and installation environment.
• Detailed anatomical shapes and structures were accurately reproduced.

Conclusions:

• Binder jet rapid prototyping is a viable and accurate method for craniomaxillofacial surgery.
• The technique offers significant advantages over laser lithography for medical applications.
• Binder jetting with starch is highly useful for surgical simulation and implant design.
