Forma3D is a professional 3D mesh editor for iPhone and iPad — built for makers, 3D printing enthusiasts, and anyone who needs to create, fix, or modify 3D models on the go. No laptop. No cloud. Everything runs locally on your device, offline, with desktop-grade mesh editing. ▸ PAINT & MULTI-FILAMENT 3MF EXPORT Paint with a brush directly on your model, then export a 3MF file with per-face color data ready for multi-filament printing. Bambu Studio and Creality Print read the embedded colors automatically — your paint job travels to the slicer intact. ▸ SCULPT MODE Sculpt meshes with a gesture-based brush — push, pull, and smooth with falloff presets and Apple Pencil support. ▸ SKETCH MODE Draw a shape or import an SVG and turn it into 3D geometry in one tap. ▸ LITHOPHANE GENERATOR Turn any photo into a printable lithophane — a depth-mapped relief that comes alive when backlit. ▸ SPLIT WITH JOINTS Split meshes along edge loops into printable parts with built-in joints — cylinder, square peg, cone, or ball. Perfect for models bigger than your build plate. ▸ EDGE LOOP TOOLS Select entire edge loops and fill them with clean topology: Grid Fill for quad surfaces, Bridge for connecting boundaries. ▸ MESH EDITING AT YOUR FINGERTIPS Switch between Object Mode and Edit Mode. Select and edit vertices, edges, and faces with Single, Rectangle, Oval, or Brush selection. Move, rotate, and scale with a transform gizmo or numeric input. ▸ PROFESSIONAL MODELING TOOLS • Extrude — live preview with direction toggle • Inset — adjustable depth • Bevel — custom segments and profile control • Boolean — Union and Subtract (Manifold CSG) • Cut — Line, Circle, Ellipse, Rectangle, Polygon, Freehand • Mirror — across X, Y, or Z • Revolve — lathe geometry from a profile • Subdivide / Simplify — resolution where you need it • Remesh — uniform quad topology with quality control • 3D Text — extruded text objects ▸ PRIMITIVES & IMPORT Cube, Sphere, Soft variants, Cylinder, Torus, Pyramid, Plane, Tube, Bolt, Nut. Import STL and 3MF. Export to STL, 3MF, USDZ. ▸ 3D SCANNING (LiDAR) Scan real objects and edit the mesh immediately — scan, fix, print without switching apps. ▸ PRECISION & MEASUREMENT Ruler in millimeters, 20 mm build-plate grid, snap-to-grid, keyboard numeric input. ▸ VISUALIZATION Orthographic view cube, X-Ray mode, wireframe (triangles/quads), custom lighting and viewport colors. ▸ UNDO / REDO & PROJECTS Full history, native .forma3d projects, objects list panel. ▸ APPLE PENCIL Hover tooltips and precise component editing optimized for Pencil. ▸ 16 LANGUAGES English, Deutsch, Français, 日本語, 简体中文, Español, Italiano, 한국어, Português, Русский, Nederlands, Polski, Türkçe, 繁體中文, Svenska, العربية. Whether you're splitting a big print into jointed parts, painting for multi-filament output, sculpting freehand, or fixing a scan — Forma3D puts a desktop-grade mesh editor in your pocket.
