How Is A Plaster Replica Scanned In Order To Create An Accurate Digital 3d Model Of Gold-Plated Coins Or Medals?
The process employs special equipment to digitize the maquette and then capture its dimensions. The digital replica serves a variety of purposes during the production process.
3D Scanning Technique- High resolution 3D scanners can be used to record dimensions and other details on models made of plaster. These scanners utilize various methods such as laser scanning and structured light to capture precise measurements and geometrical shapes.
Capturing Surface Information - The scanner projects light or laser beams onto the the plaster model. The scanner captures the reflections and distortions that these beams cause, capturing surface information.
Data collection - The scanner captures data while it moves over the model. This creates an image that is digitally rendered, which includes the model's contours, geometry and details.
Conversion into a 3D Model. The collected information is processed using special software which reconstructs it into a 3D digital model. This model mimics the physical dimensions and features of the maquette.
What are the reasons for making the digital 3D model?
Digital 3D models allow for accurate reproduction of the physical model's dimensions and details. This precision is vital for ensuring that the final gold coins or medals conform to the original style.
Digital models can be easily modified or upgraded. Designers can modify the 3D models without altering the initial plaster model.
Compatible with Manufacturing Processes- Digital 3D models are compatible with a variety of manufacturing techniques, such as 3D printing or CNC machining, facilitating the production of molds or dies for mass production.
Digital 3D Models serve as a document for the design. Digital models can be saved to be used in the future, reproduced or historical documentation.
By scanning models of plaster and creating 3D digital model Designers and manufacturers can speed up their processes of production and ensure the accuracy of reproduction and utilize advanced manufacturing technology to create gold coins and gold medals with a high degree of precision and fidelity.

Correction of Imperfections
Engravers are able to correct any flaws or inconsistencies within the transfered design. They can employ precision tools to rectify minor errors, adjust depths, or refine particular elements to ensure consistency and accuracy.
Enhancing Details
Employing special engraving tools like gravers, burins, or pneumatic engraving machines skilled engravers create elaborate details to the design. The engravers carve into the surface of the working hub to create intricate patterns, textures, letters, and intricate designs as needed by the design.
Dimensional Enhancement and Depth
Engravers modify the contours and depths of the design to create visual dimension and depth. The depth of the cut is altered to emphasize specific features and give a sense or texture.
Textured and finished touches
Engravers can provide texture or finish to certain elements of a design in order to make it appear more attractive. Techniques like stippling, frosting or other types of shading are employed to achieve varying surfaces or effects.
Quality Control Inspection
Engravers conduct numerous checks and inspections throughout the process of engraving to make sure that their designs meet the standards of clarity and accuracy.
