Molds for the production of footwear
Use of the 3D scanner in the footwear industry
Open Technologies has been established with the purpose of design and produce optical 3D scanners for the dental and
Thanks to the constant rogress of the R&D department, and thanks to the company’s investments in the innovation field, Open Technologies is today a leader on the market of the scan systems.
Cronos3d is the latest 3d scanner developed by Open Technologies for the Italian footwear industry. Dozens of highly specialized firms dopted this cutting-edge technology, fully designed, developed and manufactured in the italian headquarter of Open Technologies.
Heels, soles, lasts, molds, shoes and accessories can be rapidly digitized and engineered. Optical 3d scanning is now an integral part of the manufacturing processes of the footwear industry, a Must in order to stay (to keep your manufacturing plants) in step with the times.
The prototype of the sole is carved in
the style department and completed
by the modeller, it is then, digitized in a matter of minutes. (Polygonal meshes, STL OBJ PLY).
CAM – Results of a digitization with
Cronos3d are directly importable in
most of the CAM environments for the
Appropriate scaling allows the
development of the entire range of
sizes. Every model is then milled.
The prototype of the heel is carved in the style department and completed by the modeller, it is then, rapidly digitized. (Polygonal meshes, STL OBJ PLY)
Workflow #1 – The polygonal mesh obtained by Cronos3d is imported directly in a CAD system for a complete reverse engineering and design of the resulting mold. At this point, results are imported in the CAM software for the toolpath generation.
Workflow #2 – Toolpath are generated directly on the polygonal output of the 3d Scanner or, after a reverse engineering process, on the resulting CAD solid. The prototype is used as a foundation for manufacturing a casting mold of the milled part.
• 3D Scan of the last, acquisition of the shape and figures (polygonal mesh STL OBJ PLY)
• Reverse engineering of the last
• CAD – Design and development of the different parts of the shoe based on 3d scan data Heel, Uppers/Vamp, Counters,
Insoles and Soles.
Mold cover from hollow casting
1) Aluminum casting on the sole model (hollow casting).
2) 3D scan of the resulting mold (Polygonal mesh STL, OBJ PLY).
3) CAD – Parting line detection, reductions and simplifications
through offsets and scan data sections.
4) CAM – Machining of the mold cover from CAD results.
Reverse Engineering & Rendering - Entire Shoe
• 3D Scan of the finished shoe, colors and textures acquisition (Polygonal mesh STL OBJ PLY)
• Rendering and cataloging
• CAD – Reverse engineering of the different components of the shoe based on 3d scan outputs.
Optical Reveng*, besides acquiring, registering, processing and editing the polygonal mesh, allows plane intersections for crosssections on the model and smart curves detection (manually with control points or automatically based on curvature).
The exported Polylines can be imported as an IGES in any cad environment as a support for the reverse engineering process.
