How to edit 3D models to prepare them for 3D printing services?

To edit 3D models for 3D printing services, one can utilize indirect editing methods like 3D Gaussian Splatting (3DGS), which involve making edits in a rendered 2D space before applying them to the 3D model. This process works by leveraging 2D diffusion models to guide the optimization of 3D representations, allowing for iterative adjustments while maintaining some degree of multi-view consistency. For instance, recent studies have demonstrated that using 2D-guided editing can significantly enhance the quality of 3D models, as evidenced by advancements in 3DGS techniques that effectively bridge the gap between 2D edits and 3D model integrity, despite the challenges posed by the lack of paired data for supervised fine-tuning.
