Blue3D Maker Tools / Member beta
Line art to a printable sand mold.
Upload a clean drawing, tune the wall and detail settings, and download a watertight STL. You choose the slicer, filament, and printer profile.
Sand Mold Studio is the first Blue3D Maker Tool. Member access is rolling out in private beta.
STL only
Designed in Blue3D. Sliced your way.
The studio generates the geometry. It does not prescribe printer profiles, materials, layer heights, or slicers. That stays in your hands.
Tune the mold
Set size, wall height, wall thickness, embossing, and curve cleanup.
Download STL
Open the finished watertight STL in the slicer you already trust.

A growing library
Sand Mold Studio is only the start.
Blue3D Maker Tools will bring together practical, printable generators for hobbyists who want useful custom parts without starting every design in CAD.
