SPLIT
STL Splitter
Split a model that is larger than your printer into printable, keyed parts. AutoMold3D checks the selected build volume and can add connectors only on safe cut interfaces.

Free Online 3D Printing & Mold Tools
Choose a focused workflow. Each page opens the same production tool used in the mold studio, without a duplicate geometry engine.
REPAIR
STL Repair
Inspect a mesh before printing and use the optional repair pass to weld tiny gaps and validate topology. Review the result visually before using a repaired file in a slicer or mold workflow.
Open tool →OPTIMIZER
Mesh Optimizer
Reduce triangle density before heavy model splitting while reviewing the optimized mesh beside the source. Choose a reduction target and download the result only after you are satisfied with the visible detail.
Open tool →MOLD
STL Mold Generator
Create a configurable two-part rigid mold from a supported mesh file. Set wall thickness, model clearance, parting controls and alignment settings, then inspect and download printable STL parts.
Open tool →TRAY
Tray Mold Generator
Arrange one or more uploaded models into a flat-base multi-cavity tray mold workflow. Choose cavity count and spacing, then create a printable tray master with the same in-browser geometry system.
Open tool →VASE
Vase Mold Generator
Generate a mold workflow for hollow, open-top shapes such as vases and planters. The vase preset uses a base, carrier halves, an inner core and an upper ring with core clearance measured in millimeters.
Open tool →PRESS
Press Mold Generator
Create a female cavity and male piston workflow for shallow press work. The press configuration uses Z-axis split movement and keeps the male piston as the lower half for the studio preview and output.
Open tool →ADAPTIVE
Adaptive Shell Mold
Create a lightweight shell that follows the model with a flat base, split plane controls, matching pins and clips. Use the model-to-shell clearance setting to keep the generated shell away from the mesh.
Open tool →ADAPTIVESILICONE
Adaptive Silicone Mold
Generate a lightweight model-following shell with a split plane, base-channel logic, pour opening and separate U-clips. Control shell thickness and the model clearance before creating printable parts.
Open tool →MOLDSPLIT
Mold Splitter
Upload an existing mold STL and split its printable bodies to a chosen printer volume. The same production splitter can add safe mating pins, sockets and sealing channels across new cut interfaces.
