How Lets3dPrint compares
There are great CAD apps for engineers and great toys for first steps. Lets3dPrint sits between them: exact, editable solids like professional CAD, with the printing details built into the tools, no account, and a price made for a hobby.
Feature by feature
Eleven things the others do not have at all
Side by side with the six Mac App Store apps closest to Lets3dPrint. Each row is a tool that is built in here, with one click and a preview, and that none of them offers in any form.

|---|---|---|---|---|---|---|---|
| Texture that becomes real faces and edges | Knurl, weave, wood and 13 more patterns on exact solids; each knurl facet a real face you can fillet, sketch on and export to STEP | ||||||
| Waves from drops | Click where drops fall on any surface; rings run over it and add up where they meet | ||||||
| Lampshades and vases from lines | A profile and a path formula: lines wind over the shape, cross into a net and print as one solid | ||||||
| Smart objects sized by their place | One part placed over a face, a grid or points; a formula of x, y, z sizes each copy; edit it once, all follow | ||||||
| Spreadsheet to solid | A CSV becomes bars, a surface or columns on a plinth, ready to print | ||||||
| Split with locks that print | Joint Split cuts a big part into pieces that lock with jigsaw or dovetail joints, with the clearance your printer needs | ||||||
| Twist locks: push and turn | A bayonet joint on any cut: lugs, slots, a groove and a click, made for printing | ||||||
| Your timeline as a script with sliders | Every step as readable text; numbers become sliders; loops and formulas build what clicking cannot | ||||||
| Formulas and gyroids as solids | A height formula z = f(x, y) or a shape f(x, y, z), gyroids included, as a solid you keep editing | ||||||
| Real terrain from height data | Height maps, GeoTIFF and SRTM tiles, or generated hills, as a printable solid | ||||||
| Print fixes as design steps | Teardrop tops for sideways holes, bridge layers in counterbores, brim ears on sharp corners, a chamfer on the bed edge |
Checked against each app's Mac App Store listing, website and help pages as of October 2026. "Not offered" means there is no tool for it; anything can be modelled by hand, piece by piece, in a CAD app. Outside the App Store, Autodesk Fusion has image textures for mesh bodies (Texture Extrude), and Fusion, Onshape and FreeCAD reach some of these through add-ins and scripts. Apps and their features change. Shapr3D, OpenShape3D, Part3D, Quick3DModeling, 3D Print Designer CAD and Forma3D are trademarks of their owners, named only for comparison.
How it compares
CAD made for the printer, not for the factory
There are great CAD apps for engineers and great toys for first steps. Lets3dPrint sits between them: exact, editable solids like professional CAD, with the printing details built into the tools, no account, and a price made for a hobby.

|---|---|---|---|---|
| Exact sizes, steps you can change later | Every step stays in a timeline you can reopen | Yes | Yes | Shapes and holes, no step history |
| True solids for the slicer | STEP, 3MF with each body in its colour, STL | STEP, 3MF, STL and more | STEP, 3MF, STL and more | Mesh files such as STL |
| Printing built into the tools | Wall and gap check for your nozzle, threads with clearance, teardrop holes, bridge layers, bed chamfer, brim ears, the printer's bed | General tools; print details are up to you or an add-in | Through add-ons and macros | Not the focus |
| Texture on faces | 16 patterns on exact solids, as real faces and edges if you like, plus waves from drops, checked against your nozzle | Image textures on mesh bodies (Fusion), add-ins, or looks only | Through add-ons | No |
| Design once, use many times | Smart objects over points, grids or surfaces, sized by their place; a library of 13 editable parts | Components and part libraries | Links and add-on libraries | Fixed shapes to drag in |
| Data from a spreadsheet | CSV to bars, surfaces or columns, ready to print | Through scripts | Through scripts | No |
| Parts bigger than the bed | Joint Split with jigsaw or dovetail locks, and twist locks that push and turn | Split, then model the joints by hand | Split, then model the joints by hand | Not the focus |
| Maps and maths as solids | Height maps, GeoTIFF, SRTM, generated terrain, formulas, gyroids | Through scripts or add-ins | Through add-ons and scripts | No |
| No account, works offline | Projects are ordinary files on your Mac | An account, and often a cloud for your projects | Works offline | An account and a browser |
| Learning curve | Every tool works one way: pick, drag or type, OK | Deep tool sets that take a course to learn | A steep start | Minutes |
| Ease of use | Live preview, values typed right on the model, OK only when it works, every tool by name with ⌘K | Powerful, but many menus, modes and settings | Dense interface, tools spread across workbenches | Drag and drop, very simple |
| Priced for a hobby | Free to model; Pro $0.99 a month or $6.99 a year | Limited free plans; professional subscriptions | Free | Free |
When to pick something else
If you need assemblies with moving joints, 2D drawings for a machine shop, CAM or simulation, professional CAD does that and Lets3dPrint does not try to. If you want to build with blocks with a child in a browser, Tinkercad is lovely. Lets3dPrint is for the part in between: the bracket, the enclosure, the knob, the map, the thing that has to fit and has to print.
