What This Research Demonstrates
The publication documents commercial case-study experience with an industrial workflow in which mold production is driven by digital data rather than by physical tooling. Each stage below reflects the sequence discussed in the paper.
- 1
Existing or damaged component
An in-service, worn, damaged, or obsolete cast part is the starting point when no usable pattern or drawing set remains.
- 2
3D scanning or existing engineering data
Geometry is recovered from the physical component by 3D scanning, or taken from whatever drawings or CAD data are still available.
- 3
Digital engineering data
The recovered geometry is prepared as a digital model that also carries the mold, core, and feeding arrangement.
- 4
3D sand printing
Mold and core sections are printed directly from the digital data by binder jetting, without cutting a physical pattern.
- 5
Patternless mold production
Printed sections are assembled into a complete mold package ready for pouring.
- 6
Metal casting
The assembled mold is poured in the required ferrous or non-ferrous alloy and the casting is finished and checked.
- 7
New or replacement cast component
The result is a new or replacement casting produced from digital data rather than from conventional tooling.
This sequence matters when conventional patterns or original engineering drawings no longer exist. Because the mold is generated from digital geometry recovered from the component itself, the route to a replacement casting does not depend on surviving tooling or a complete original drawing set. See also reproducing a cast part without original drawings.
