Looking for beta testers: Built a dedicated Windows 3D Nesting software for SLS printers
Over the past few months, I’ve been developing a standalone Windows application called 024Nester, designed specifically for 3D nesting and build prep in SLS 3D printing workflows.
As someone working with additive workflows, I felt there was a gap for a lightweight, dedicated tool focused purely on fast, high-density 3D packing and clean part handling.
024Nester features a fast volumetric nesting engine optimized for SLS powder-bed builds. It takes standard STL input geometries and exports the fully nested batch back out as positioned STL files, ready for your existing machine setup. The app is a self-contained .exe installer developed in Python and compiled for Windows x64.
Regarding privacy and security, 100% of the geometry processing, calculations, and STL exports are executed locally on your machine. Your STL files and personal data never leave your local system. Internet connectivity is strictly used for a quick online license check during the STL export process.
The core nesting engine and batch handling are fully functional, and I’m now looking for beta testers from the community, especially operators running SLS hardware or managing print service bureaus.
I’m mainly looking for feedback on real-world stress testing with complex or high-count batch geometries, packing density, calculation speed, and overall workflow usability.
If you’re interested in giving it a spin and sharing raw feedback, drop a comment below or send me a DM, and I'll send over the installer link.
Thanks for your time and feedback!
