objekto vs Adam (AdamCAD): which should you use?
Updated 5 November 2026 · 2 min read
In short
Adam (AdamCAD, a Y Combinator company) turns text into a parametric CAD part: the AI writes OpenSCAD, every dimension becomes a slider, and you export an STL to print yourself. objekto also designs in parametric CAD, but aims at complete multi-part objects (up to 12 unique parts), with an exploded view and assembly guide, and takes care of manufacturing and delivery. For a simple part you print at home, Adam is enough; for a finished object delivered to your door, objekto.
- Adam: chat + viewer, OpenSCAD, one slider per dimension, STL, OBJ, SCAD and DXF exports.
- Public prices at the time of writing: limited free tier, Standard $5.99/month, Pro $17.99/month.
- No manufacturing: you need a printer or a print service.
- objekto: multi-part, a material per part, printability checks, a delivered order.
What Adam does
Adam is a text-to-CAD tool from a start-up that went through Y Combinator (Winter 2025 batch). The interface pairs a chat with a 3D viewer; the language model writes OpenSCAD code that runs in the browser. Every numeric dimension becomes a slider, and you can select part of the model to edit it locally. Exports are STL, OBJ, SCAD and DXF. An open-source version, CADAM, is on GitHub.
A 2026 review notes that dimensional consistency degrades beyond eight to ten components, and that you only get the sliders the AI chose to expose. In autumn 2026 the company also launched a copilot inside professional CAD software (Onshape, Fusion), with an API and an MCP server.
What objekto does
objekto starts from a description, a photo or a sketch: its AI designs the object as parametric CAD, part by part, checks it's print-ready, provides an exploded view and an assembly guide, then has it made by an industrial 3D-printing workshop and delivered in France. A simple part costs 950 credits to design, and new accounts get 2,000 credits free at signup.
The differences, point by point
| Adam | objekto | |
|---|---|---|
| Model type | Parametric CAD (OpenSCAD) | Parametric CAD (build123d) |
| Multi-part objects | Possible; consistency drops beyond 8–10 components (per one review) | Up to 12 unique parts, clearances and collisions checked |
| Printability check per material | Not advertised | Yes, the workshop's rules for each material |
| Exploded view and assembly guide | No | Yes |
| Exports | STL, OBJ, SCAD, DXF | STL, 3MF, STEP (paid plans), source code (Pro, Studio) |
| Manufacturing and delivery | No | Yes |
| Price | Limited free tier, $5.99 or $17.99 a month | 2,000 credits free at signup; plans from $29 a month |
When to pick Adam
- You own a 3D printer and want a simple part, fast.
- You want the OpenSCAD code or a DXF export.
- You already work in Onshape or Fusion and want a copilot.
When to pick objekto
- You want a finished object, made in an industrial material and delivered.
- The object has several parts, in several materials, to assemble.
- You want printability checked against the material, plus an assembly guide.
Frequently asked questions
Does objekto use OpenSCAD?
No: objekto generates build123d (Python) code, run in a sandbox, then exports the parts as STL, 3MF and STEP.
Can I print an objekto design myself?
Yes: on paid plans you can download the files and print them wherever you like.
