v3.1 beta · free while in beta
From CAD to print-ready,
in one studio.
PowderFAB Studio prepares parts for powder-bed printing: 40 lattice unit cells with gradients, supports that break away cleanly, and the build-prep tools in between. Everything is computed on your own PC.

01Build prep
Everything the build plate needs
Bring in STEP or mesh files, arrange them on the plate and clean them up. Every part gets the same inspector, and STEP parts keep their exact geometry.

02Lattice Studio
40 unit cells, graded where you need them
TPMS sheets and networks, struts, stochastic foams and auxetic cells, clipped to your part. Grade the cells, blend the joints smooth, keep a solid skin.

03Support Studio
Supports that come off cleanly
Structured walls with breakaway teeth, perforation and fragmentation, generated per overhang. Mark what the detector missed, then edit any support by hand.

Also in the studio
Orientation optimizer
Searches build orientations for the least overhang area before supports go on.
Plane and polygon cut
Split, keep one side, or cut along a polyline, with capped faces.
Mesh repair
Fills holes and fixes normals on imported meshes.
Array duplicate
Copies a part on a grid, with the spacing you set.
Effective properties
Relative density, stiffness and Poisson’s ratio of the cell you chose.
STEP in, STEP out
STEP parts keep their exact geometry; export to STL, 3MF, OBJ, PLY or STEP.

If PowderFAB has helped you, please consider supporting the development roadmap — the FEM module and generative design optimization depend on it.
Frequently asked questions
PowderFAB reads CAD STEP files (.step, .stp), STL, Wavefront OBJ, 3MF and GLB/glTF. STEP parts keep their exact B-rep geometry. You can export to STL, 3MF, OBJ, PLY or STEP. Everything is converted locally on your machine.
No. All geometry work — import, lattice generation, supports, booleans and export — runs 100% locally on your machine. No design file ever leaves your computer.
The MSI installer installs PowderFAB Studio into Program Files, with optional Start-menu and desktop shortcuts, and can be removed from Windows Settings. The portable ZIP needs no installation: extract it anywhere (a USB stick works too) and run the .exe.
Yes. Beside the 40 library cells (TPMS sheet and network, strut, stochastic and auxetic), you can define a TPMS surface with your own equation, or draw a custom strut cell from nodes and struts — with gradients and alignment on all of them.
The beta installers aren’t code-signed yet, so Microsoft SmartScreen may show a “Windows protected your PC” screen the first time you run them. This is Windows’ standard caution for new, unsigned files; it doesn’t mean anything harmful was found. Click More info, then Run anyway. To confirm your download is authentic, your download email includes the file’s SHA-256 checksum: run Get-FileHash on the file in PowerShell and check that the hashes match. Code signing is planned as the beta matures.
Windows 10 or 11. Lattice generation, supports and booleans run on the CPU, so a modern multi-core processor matters more than graphics power; any graphics chip of the last ten years, integrated ones included, is enough for the 3D viewport. At least 8 GB of RAM is recommended.
