Today, contact free methods need to be used to produce replicas. These tasks can be performed by 3D scanning and 3D printing. Non-contact 3D scans capture the original in a gentle yet highly detailed way. This data can then be used for digital presentation or prepared for 3D printing.
The 3D scan is based on a 50-year-old cast of an original. It did not need to be reworked as we were able to capture the object from all directions.
After printing in light gray resin, the print was freed from supports and cleaned in an isopropanol bath. The blank was then finally cured in a UV oven.
PU varnish adheres excellently to the resin surface, which is why I prefer it as a primer. After 24 hours, the paint is applied in layers to achieve a sand-colored tone. Various acrylic paints and washes are used for this.
