A goldsmith relies on 3D printing

At the AMX 2019 goldsmith and industrial designer Manuela Weingart demonstrated how she uses additive manufacturing to create the positive form for her jewelry designs. This not only saves her time but also enables her to meet her customers' wishes quickly and easily.

What goldsmith and industrial designer Manuela Weingart previously carved out of a wax block can now be produced with the 3D printer thanks to additive manufacturing.


The advantages are obvious

Often the customer imagines the result differently since a sketch leaves room for interpretation. Changes - especially to the size of the jewelry - can only be made at the end of the process with considerable additional effort.

With a 3D model in the CAD program, the industrial designer can show her customers what the finished individual piece looks like right at the start of the work process. Adjustment requests can be implemented quickly and easily at this stage.

The CAD models are also ideal for using visualizations of the jewelry on your website or at customer presentations.

Prices are also lower in some cases, especially for jewelry that is produced in duplicate (e.g., wedding rings or earrings). So the positive forms do not have to be worked out twice out of a wax block in tedious manual work but are simply printed a second time in 3D.


From the sketch to the finished design:

1. Weingart uses a sketch to visualize the final result of the jewelry to her customers.

2. In a second step, she sketches a 3D model in the CAD program.

3. The wax 3D model is printed to be used as a casting core in the next step.

4. In a fourth step, the wax figure is wrapped in a plaster coat. The wax figure is then melted at an elevated temperature and the plaster mold is hardened.

5. The resulting cavity can now be filled with the desired material.

6. In a sixth step, the mold is broken, and the model is revealed.

7. Weingart finishes the model in traditional craftsmanship. In doing so, she removes the remains of the first cuts, and plasters and polishes each of her pieces by hand.


Strong partnership: Industrial designer Manuela Weingart and Z.E.C. AG

This example once again demonstrates the versatility of 3D printing today.

Weingart holds a Bachelor degree from FHNW for design and art in product and industrial design. Thanks to the collaboration with the industrial designer, Z.E.C. AG can offer you complete solutions including industrial design.
