Upload your CAD. Buildable fixes it for how it's made.
Buildable understands the geometry, the manufacturing process, and the constraints that matter, helping you find problems, fix supported issues directly in the geometry, and move toward manufacturing with confidence, all locally in your browser.
Your CAD can be finished and still not be manufacturable.
CAD software tells you geometry, dimensions, and features. It doesn't tell you whether a given process can actually make what you drew. Process limitations, tooling access, wall thickness, draft, orientation, tolerances, assembly fit, and material behavior all live outside the CAD file. CAD tells you what you designed. Buildable helps you understand whether you can actually make it.
Overhangs
A 45° unsupported face looks fine in CAD. In FDM, nothing beneath it to bond to means it droops or fails mid-print.
Tool access
A sharp internal corner is one clean edge in CAD. No round end mill can cut it; a real tool always leaves its own radius behind.
Draft angle
A dead-vertical wall renders perfectly in CAD. Without draft, the mold can't release the part without scraping or sticking.
Assembly fit
Two parts can look correct individually and still quietly overlap in space once assembled, if nobody explodes the model to check.
Most DFM tools give you a list. Buildable gives you a fix.
Buildable doesn't just tell you what's wrong. Where supported, it helps fix the CAD directly, real STEP geometry operations, not a visual overlay.

From CAD to confidence.
Not upload CAD, receive a list of warnings. Analyse, understand, fix, recheck: a loop, not a one-shot report.
Analyse
Upload your STL, 3MF, or STEP file and choose the manufacturing process. Real geometric analysis, not a generic checklist.
Understand
Buildable identifies issues, prioritises them by severity, and explains what matters and why for the process you chose.
Fix
Preview and apply supported geometry changes directly, real CAD-kernel operations on STEP models, not a visual overlay.
Recheck
Buildable validates the revised design against the same manufacturing constraints and shows exactly what changed.
Buildable doesn't apply generic rules to every file.
The same geometry can have a completely different manufacturability outcome depending on how it's made. This is one real part, Buildable's own sample assembly (a 13-part compact linear actuator), checked against four processes with nothing else changed.
9 critical findings, starting with a thin wall. A 13-part assembly printed as one merged shell has plenty of places to be too thin.
15 flagged features, starting with a sharp internal corner no round end mill can cut cleanly, none of them critical, all of them real.
9 critical draft-angle findings. Walls with no draft at all, fine for machining or printing, would scrape or stick pulling this part from a mold.
No bend-radius or flange issues found, for a part that wasn't designed as a sheet-metal part in the first place.
This is Buildable's real sample assembly, checked live through the actual per-process engines, not a mockup. See the full example.
Choose how you're making it.
Every check runs client-side the moment you drop a file in, and names what's measured, what's heuristic, and what stays process-dependent.
Additive manufacturing
FDM and SLA: overhangs, thin walls, bridging, tip-over risk, trapped resin.
Machining
CNC: tool access to internal corners, deep and narrow pockets.
Moulding
Injection moulding and casting: draft angle, wall uniformity, undercuts.
Forming
Sheet metal: bend radius, hole placement, flange length, bend relief.
See the full manufacturing process breakdown, every check, every process, in detail.
Supported issues get fixed directly in the geometry.
Automatic where it's safe. Asked where it matters.
Buildable distinguishes between refining geometry that's already there and adding new geometry that changes the design. Both are labeled clearly, and only one of them needs your approval. Buildable never silently changes design intent.
Buildable checks real assembly geometry, not just individual parts.
A multi-solid STEP import splits into its real, independent parts via the CAD kernel itself, not a mesh heuristic. Every pair of parts close enough to matter gets a true solid intersection where supported: if two solids genuinely overlap, Buildable reports the exact overlap volume in mm³, not a bounding-box guess. Pull the explode slider and every part slides outward from the assembly's own center.
Every result is labeled with what kind of claim it actually is.
Buildable analyses actual CAD and geometry rather than generating generic manufacturing advice. It's designed to catch manufacturability risks early, not to replace process-specific knowledge, physical testing, or final engineering validation.
Calculated directly from the model: wall thickness, overlap volume, dihedral angle. Not an estimate.
Compared against your configured manufacturing thresholds: nozzle diameter, process, draft minimum.
An engineering approximation that may depend on process and machine, e.g. bend radius from discrete curvature.
Something that can't safely be confirmed through geometry alone: gate location, supplier tolerance capability.
See the technical detail behind each check: ray-casting, mesh topology, and the real CAD-kernel operations behind every automatic fix.
From DFM to manufacturing intelligence.
CAD describes the product. Manufacturing determines whether it becomes real. Today, Buildable is a DFM and CAD-optimisation tool. The direction is broader: connecting geometry, process, and engineering constraints into one place, without claiming to be there yet.
- Manufacturability analysis across six processes
- Geometry inspection: measured, not guessed
- Automatic CAD optimisation on supported STEP fixes
- Deeper material trade-off comparisons
- Process-to-process comparison on the same part
- Broader assembly-level intelligence
- Tolerance review, not just geometry checks
- Manufacturing trade-off reasoning across processes
- Design iteration history connected to manufacturing outcomes
The goal: Buildable as the intelligence layer connecting mechanical design to physical manufacturing, not a supplier marketplace, not project management software, not a generic AI chatbot.
Your CAD doesn't need to leave your machine.
Core geometry analysis, every DFM check, the material recommender, assembly interference, runs directly in your browser. Your CAD file itself is never uploaded to a Buildable server for that analysis.
The AI features (explaining results, planning a fix, the in-app chat) send a small, bounded summary of what your checks already found, real numbers and coordinates already computed in your browser, never raw mesh geometry, to Claude via a server-side function. That's the one feature that talks to a network service; the geometry analysis itself does not.
If you design it, Buildable helps you make it.
