Compare 4D Additive vs. Hi3D

4D_Additive, a preprocessing program for Additive Manufacturing, is designed to optimize 3D printing. 4D Additive has many features, including automatic 2D and 3D nesting and a texture module. It can read all major CAD formats either in BREP or 3D tessellated designs. The proven healing functions of CADx models automatically correct geometry errors and fill in gaps to create models that are ready for printing. Using a variety of analysis tools, you can optimize print quality and prevent printing errors. The texture module is the best on market. Our lattice options allow you to save on material while maintaining the strength of a solid printed. Our support generation is fast and easy, with customizable options to suit your needs. Export to all major slicing formats, customize and view every layer of the slicing procedure.

Hi3D is an advanced AI-powered image-to-3D generation platform designed to help creators, artists, developers, and makers generate production-ready 3D models quickly and efficiently from 2D images. Powered by the Sparc3D × Ultra3D engine, Hi3D focuses on delivering highly detailed, clean, and usable geometry with realistic textures suitable for professional creative and manufacturing workflows. The platform reconstructs both visible and hidden surfaces to create complete 3D objects rather than flat approximations, making the resulting assets suitable for applications such as 3D printing, game development, animation, film production, architecture, product design, and digital art. Hi3D supports single-image and multi-view image processing to generate accurate high-fidelity models with preserved sharp edges, realistic materials, and human-like detail. The platform includes AI-driven texture generation with support for 4K PBR-ready textures, allowing users to apply realistic surface materials to generated or uploaded models in one click. Advanced de-lighting technology intelligently removes baked lighting and shadows from textures to produce clean assets that can be relit and reused across production environments. Hi3D also provides specialized portrait generation tools capable of creating detailed human models with refined facial structures, skin textures, and hair-level detail at high resolutions suitable for animation, digital characters, and figurine production. Additional features include 3D relief generation from images, automated multi-color model segmentation for multi-material 3D printing, and one-click export to slicing software such as Bambu Studio and OrcaSlicer.
