Forma3D

Powerful 3D editor for mobile. Create, edit, and prepare models for 3D printing with professional precision tools.

Forma3D is a convenient 3D editor for iPhone and iPad that lets you quickly prepare models for 3D printing right on your device. Create objects from scratch, edit shapes with precise tools, and export results to STL or 3MF for your slicer. The interface is beginner-friendly while providing advanced tools for accurate model refinement.

Forma3D Features:

Primitives: Create cubes, soft cubes, spheres, soft spheres, cylinders, tori, pyramids, planes, tubes, and 3D text—with soft/smooth variants for organic shapes.

File Support: Import/Export STL, 3MF.

Precise Transformations: Position, rotation, and scale with exact controls.

Boolean Operations: Union and subtract using the Manifold CSG engine for clean, manifold-safe results.

Manifold Cut CSG: Slice objects with line, rectangle, ellipse, circle, or freehand-drawn tools—perfect cutlines, ready to print.

Mesh Editing: Edit vertices, edges, and faces directly. Extrude, inset, and bevel faces. Toggle flat or smooth shading per object.

Selection Tools: Single, rectangle, oval, brush, and multi-selection.

X-Ray Mode: Adjustable transparency, wireframe overlay, and ghost mode.

Scene Navigation: View cube, frame to selection, and camera pivot modes.

Object Management: Undo/redo, duplicate, delete, and object list.

Forma3D helps you go from idea to ready-to-print model faster and simpler—without complex desktop software pipelines.
