Verified cavity graph
See every internal cavity, outside connection, bottleneck, drain, and vent.
Resin Safety Preflight
Hollow resin models without hiding a sealed failure inside.
Map every cavity, verify that drain and vent holes actually connect, protect fragile details, and recheck the model after every geometry change.
Expected outcomeA hollowing plan designed for reliable drainage, washing, and curing.
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.
Hole integrity
A visible hole only passes when it reaches the intended cavity in the exported result.
Keep Solid regions
Protect hair, fingers, cables, fire, and other details from unsafe global hollowing.
Dependent rechecks
Holes, scaling, splitting, and simplification automatically invalidate stale safety results.
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 hollow an STL without trapping resin.
Plan every cavity, bottleneck, drain path, vent path, protected detail, and final export in the actual print orientation.
Product questions
About resin safety preflight.
How many drain holes do I need?+
There is no safe universal number. Meshworthy evaluates each cavity, orientation, bottleneck, and practical wash path.
Can part of a model stay solid?+
Yes. Keep Solid regions protect fragile details while larger volumes are hollowed.
Does Meshworthy generate supports?+
No. It validates geometry before slicing and hands the result to your preferred resin slicer.
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.
