How it works

From raw scan to optimized mold in four steps

Step 1

Upload ZIP

Drag and drop a ZIP containing your STL and PTS files.

Step 2

Preflight

We detect valid STL/PTS pairs and estimate credit cost.

Step 3

Process

Our engine reduces mold height while preserving the contact surface.

Step 4

Download

Get your optimized STLs for 72 hours after completion.

Before / After

Same fit. Less resin.

Upload your raw STL — MoldLean's engine shaves the bulky base, keeps the tooth contact surface bit-perfect, and hands back a leaner mesh you can print in less time and resin.

Numbers below come from the actual engine pass on the STL shown above — not an internal benchmark.

real STL

11.0%

Less base height

17.7 mm → 15.7 mm — every layer the printer doesn't have to lay down.

12.7%

Less mesh volume

Smaller mesh = less resin per print, faster cure time, lower per-unit cost.

Reduction per case depends on the original mesh — typical range 8–20%.

Less resin per print

Same arch geometry, slimmer base.

Same fit & precision

Contact surface preserved bit-for-bit.

Faster print & cure

Smaller volume = shorter post-processing.

Lower per-case cost

Material savings stack up across batches.

Reduction percentages shown are from the CHV59L01 STL run. Real savings on your cases depend on input mesh geometry, slicer settings and resin density.
