No software to install. No complex setup. Just upload, configure and download.
Import DXF, EPS or SVG files from any vector software — Illustrator, CorelDRAW, AutoCAD or others.
Choose wall type, letter depth, face thickness, back cover options and fill patterns. Full control in one screen.
Get STL, 3MF, back cover and Plexiglas DXF files — ready for your slicer and production workflow.
Every feature designed around the real needs of professional channel letter production.
Straight, tapered and channel-lock wall types. Each optimized for different material thicknesses and letter heights.
STRAIGHT · TAPERED · LOCKSolid face, honeycomb fill or custom grid patterns. Control cell size, wall thickness and edge margin.
SOLID · HONEYCOMB · GRIDAssign different filament colors to wall, face and back cover parts. Automatic color mapping for dual/multi-extrusion printers.
MULTI-EXTRUSION READYAutomatic back cover with ventilation slots, cable entry holes and mounting tabs. Configurable inset and slot dimensions.
AUTO-GENERATEDSave your production settings as profiles. Reproduce identical results for repeat jobs with a single click.
ONE-CLICK RECALLSend finished models directly to OrcaSlicer for immediate slicing. Seamless handoff from design to production.
DIRECT SLICER EXPORTHarfex computes wall offsets, boolean operations and mesh generation automatically. You focus on design — the engine handles manufacturing geometry.
DXF/SVG paths are read, cleaned and normalized for 3D processing.
Shapely + Manifold3D computes precise offsets and boolean operations.
Watertight STL/3MF meshes ready for direct 3D printer slicing.

Harfex accepts DXF, EPS and SVG files exported from any vector software including Adobe Illustrator, CorelDRAW, AutoCAD, Inkscape and others.
No. Exports never expire. Buy once, use whenever you need. There are no monthly fees or subscription requirements.
One credit = one complete job. A job means processing one vector file with your chosen settings and receiving all requested output files (STL, 3MF, back cover, Plexiglas DXF, foam DXF). Multiple outputs from the same job still cost only 1 credit.
Harfex uses precision geometry computation with Shapely and Manifold3D libraries. Wall offsets and boolean operations are accurate to 0.01mm. The resulting meshes are watertight and ready for direct slicing.
Yes. Harfex outputs standard STL and 3MF files compatible with all slicers (OrcaSlicer, Bambu Studio, PrusaSlicer, Cura, etc.) and any FDM 3D printer.
Yes — Harfex started as a Windows desktop application and the full offline version is available. The cloud platform offers the same engine without any local installation required.
Join sign makers and fabricators who use Harfex to cut production time and improve consistency.
