3D Last System

3Shape's 3D Last System^TM is a unique application directed at shoe last manufacturers and companies in the footwear design and manufacturing industry to process, manage, and analyze 3D models of shoe lasts. The lasts are typically captured by a 3D scanner or imported from a CAD/CAM system.

Product highlights

Integration and administration
 

• Easy access to 3D last models and related information in a structured database
• Fully integrated system with a modular and scalable structure
• Integration with other systems commonly used in the footwear industry
• Intuitive and consistent user interface - minimum of system training required

Seamless interfacing

• Interface with third-party systems used by the footwear industry and ERP systems
• Import of 3D data from multiple sources, e.g. 3D scanners and CAD/CAM systems
• Export data to last and shoe design applications such as Dimensions!TM by Procam Systems GmbH, Easylast 3DTM from Newlast, or ShoemasterTM by CSM3D Ltd
• Export data to 3D printers for rapid prototyping and CNC machines for direct manufacturing of lasts
• Support for common file formats such as STL, VRML, DXF, EMF, ASC, IGES and others

Last processing and analysis
 

• Automatic processing and optimization of point cloud and surfaced 3D data
• Fast and accurate analysis and measurement of 3D lasts for quality control
• Easy comparison of CAD last models and 3D scanned last models for quality control and shape analysis
• Seamless 3D last modeling operations, such as adding height for an insole, changing the toe and heel spring, or merging two distinct lasts

Overview of the 3D Last System Modules

3Shape's 3D last system is built on a flexible and scalable platform consisting of a number of complementary modules with specific functionalities. This structure allows the system to be configured to suit specific needs of a given user. New individual modules can easily be added to an existing system.

The following overview presents how the system's modules are linked to each other:

3D Last Manager The 3D last manager module is at the core of the 3D Last SystemTM. It includes a database to store 3D last models and related last information. The database can be searched and browsed at any time using various search criteria. The 3D Last ManagerTM module is also used to export and import data, as well as to interface with the other system modules and the customer's ERP system
3D Scan Handling This module imports and processes point cloud data from 3D scanners. The processing operations include surfacing and optimization of the mesh created: removal of noise and artefacts and closing of holes. All operations can be performed automatically
3D Last Model Preparation This module prepares 3D last data for the 3D Last SystemTM. The system identifies the sole and the inner, outer and center lines of the last. It automatically extracts last profiles and curves
3D Last Measurement Module for analysis of lasts. A number of customer-specific measures are automatically taken to ensure consistent quality levels and to ease further reference
3D Last Comparison The comparison module is used to analyze deviations between two last models. It is possible to compare two 3D scanned lasts, or a 3D scanned last with a CAD model, or other reference model for quality control and shape analysis
3D Last Modeling The three available Last Modeling modules allow the user to transform the shape of the last. The modeling operations include adding height for an insole, changing the toe and heel spring, and merging two distinct lasts into a new last
2D Standard Comparison The 2D Standard Comparison module is used to control that 3D shoe lasts match 2D standards profiles commonly used in the footwear industry
