Printer-aware split
Use your build volume, margins, orientation, and fragile geometry instead of a generic cube grid.
Calibrated assembly
Split large STL models into parts that fit back together.
Fit oversized models to your real build volume, rank cleaner seams, add calibrated connectors, and print a test from the actual joint before the full project.
Expected outcomePrintable pieces, calibrated joinery, and a clear assembly plan.
Operation review
Checks included in this workflow.
Meshworthy shows the affected geometry, applies the selected constraints, and checks the exported result. Limitations remain visible when a result requires manual review.
Natural seam ranking
Prefer creases and less visible regions while protecting detailed surfaces.
Calibrated joinery
Tune clearance by printer and material instead of trusting a universal tolerance.
Actual-joint test
Export a small test containing the real final-scale connector before a long print.
Controlled operations
Review changes before applying them.
Each workflow identifies the affected geometry, applies relevant constraints, compares the result, and validates the exported file.
01Detect
→Locate the exact geometry and explain why it matters.
02Constrain
→Protect intent, scale, file semantics, and printer limits.
03Compare
→Preview measurable changes before applying them.
04Verify
Re-open the export and check every promised result.
Understand the problem
How to split an STL so the parts fit.
Plan build volume, seam position, strength, connector clearance, and a test coupon from the actual joint.
Product questions
About calibrated assembly.
Can it add alignment pins?+
Yes. Meshworthy supports printable connectors and separate-pin workflows, including common stock-pin sizes.
Will the pieces fit my printer?+
Candidates are checked against the selected build volume. Connector walls and clearances are validated at final scale.
Can I choose the cut myself?+
Yes. Automatic proposals remain editable, and protected regions let you tell Meshworthy where not to cut.
Local model preparation
Know before you print.
Coming soon to the Mac App Store. At launch, diagnosis will be free; Pro will unlock repair and preparation for $19.99, once — never a subscription. Model processing stays local.
