Product design & prototyping
3D models for product prototyping
Before CAD, there's the form study. Turn sketches and descriptions into 3D shapes you can rotate, render and print, in minutes instead of days.
Early product design is about exploring many shapes quickly and discarding most of them. Generated models suit that phase. They are fast, cheap and good enough to judge proportion and character. They are not engineering geometry.
Sketch to form study
Scan or photograph a shaded concept sketch and run it through image to 3D. Shading matters: a sketch with clear light and shadow gives the reconstruction far more to work with than a line drawing. Rotate the result and you'll often spot proportion problems the sketch hid.
Prompting variations
Text prompts make variation cheap. Describe the same desk lamp five ways (cone shade, dome shade, articulated arm, weighted base, clamp base) and compare the results side by side. Our prompt guide explains how to describe shape, material and style so results stay comparable.
Printable mock-ups
A printed form model, even a rough one, tells you more about size and grip than any screen. Export STL, check it is watertight, and print it at full scale. If it's too big for your printer, print it at half scale to judge the proportions.
Where CAD takes over
Generated meshes are triangle soups with no design intent: no exact dimensions, no parametric features, no tolerances. Once a form is chosen, redraw it in CAD (Fusion, Onshape, SolidWorks), using the mesh as a visual reference. Don't try to convert it.
Concept renders for pitches
For a pitch deck, a well-lit render of a generated concept communicates an idea far better than a sketch. Look at the vintage sewing machine and retro TV in our library for how much character simple forms can carry.
