What's the Difference between Filling and Filling while Hollowing?

The filling function is mainly used for dental models such as orthodontic models, working models, and study models. Dental models typically have large internal cavities, and hollowed models are prone to deformation and cracking. Filling can reinforce hollowed dental models, extending their usable lifespan.

CHITUBOX Dental slicing software provides two filling methods: an individual filling function and a filling setting integrated into the hollowing function. This article explains the differences between these two filling approaches and their respective use cases.

For Hollowed Models

The individual filling function is suitable for hollowed models, allowing users to quickly fill them. It offers four filling modes: solid, scaffold, hive, and grid structures. Among these, hive and grid structures feature through holes and dome designs, which help balance internal and external pressure during printing and eliminate internal overhangs, improving print success rates. Therefore, we recommend using hive or grid structures for dental models unless specific requirements.

When using the filling function, the model must form an enclosed cavity with the build platform. If the model edges do not fully adhere to the platform, the cutting function can be used to trim the base, ensuring a complete seal.

The solid filling mode is designed to reshape wall thickness and internal structures. If users are unsatisfied with a hollowed model, they can first apply solid filling, then set wall thickness and internal structure for re-hollowing, eliminating the need to return to design software.

For Solid Models

The filling setting integrated in the hollowing function streamlines processing for solid models. Users can simultaneously enable hollowing and configure filling parameters, completing both steps in one operation. This integrated approach simplifies workflows and saves time.

Compared to the individual filling function, the hollowing-integrated filling lacks the "solid" mode, offering only scaffold, hive, and grid structures. All other settings remain identical.

In summary, the individual filling function is for hollowed models, while hollowing with integrated filling suits solid models. Because users have diverse design habits that produce either solid or hollow models, CHITUBOX Dental supports all cases to guarantee efficient filling for any model.

If troubled whether to hollow models in design software, we recommend keeping them solid and using the "filling while hollowing" function in CHITUBOX Dental for more efficient one-step processing.
