Forma3D vs MeshVault

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 & FILE FORMATS Cube, Sphere, Soft variants, Cylinder, Torus, Pyramid, Plane, Tube, Bolt, Nut. Import STL, 3MF, OBJ, PLY, DAE, ABC, USD, FBX and GLB — plus native Blender .blend scenes with mirror modifiers and object transforms applied. Export to STL, 3MF (Bambu-ready), OBJ, FBX, GLB or USDZ — with colors. ▸ 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. ▸ 21 LANGUAGES English, Deutsch, Français, 日本語, 简体中文, 繁體中文, Español, Italiano, 한국어, Português, Русский, Українська, Nederlands, Polski, Türkçe, Svenska, العربية, हिन्दी, ไทย, Tiếng Việt, Bahasa Indonesia.

Open a 3D file, look at it properly, and get the numbers you actually need. OPENS WHAT YOU ALREADY HAVE STL, OBJ, FBX, PLY, GLB/glTF, 3MF, USDZ, DAE and Alembic. Drop in a ZIP, 7z or tar.gz and the models inside open directly - no unzipping first. If an archive holds a whole assembly, tick the parts you want, or load all of them at once. BUILT FOR BIG FILES A 1.2 GB assembly with millions of triangles loads without falling over. When a model is larger than the device can hold at full precision, it is reduced automatically so you still get to see it, and a banner tells you exactly what happened. EXPLODED VIEW Drag the slider and the parts move outward from the centre - the assembly opens up like a workshop diagram. Drag it back and everything returns to where it was, exactly. Files loaded together from an archive separate part by part. MEASURE AND WEIGH Tap two points for a distance in mm, cm, m or inches. Pick a material - PLA, ABS, PETG, resin, nylon, aluminium, steel, stainless, brass, copper, titanium, gold, silver, wood or your own density - and get the weight, alongside volume, surface area, bounding box and triangle count. Volume comes from the full-precision mesh, so simplified display never changes the numbers. SEE IT THE WAY YOU WANT Front, back, left, right, top, bottom, isometric, and fit to view. Lighting follows the camera, so the underside is as clear as the top. Set the model colour, the background, the light direction and its strength. CONVERT BETWEEN FORMATS Export what you opened as STL, OBJ, PLY, GLB, 3MF, FBX or USDZ. Handy when a printer wants STL and the model arrived as FBX. ALSO A WORKING ARCHIVE TOOL Extract any ZIP, 7z or tar.gz, 3D file or not, and save the contents to Files. Compress files into a standard ZIP anyone can open. Everything runs on the device. Nothing is uploaded. One-time purchase removes ads, drops the watermark from exported images, and unlocks unlimited format conversion. Free without it: three conversions, plus one more each time you watch a short video, up to five a day. Not supported: RAR archives, and CAD formats such as STEP or IGES.
