China3D printingNet April 20th, Italian luxury jewelry supplier Promotion SpA has adopted INTAMSYS additive manufacturing tools to optimize the product assembly process.
By using INTAMSYS 3D printing, Promotion SpA is able to create a powerful new bracelet calibration tool that can withstand multiple test cycles without scratching the exquisite appearance of the product. The revised tool can enhance the company’s internal production capabilities, and the company has become a close manufacturing partner for many high-end watch and accessory brands.
Federica Tiso, R&D materials scientist at Promotion SpA, said: “We control the entire process. From design and prototyping to manufacturing, quality control and logistics. Together with the ability and skills to develop and manufacture custom bracelets, we can provide customers with complete solutions .”

Speed up jewelry prototyping
Promotion SpA is headquartered in the fashionable Italian city of Vicenza, surrounded by the emerging fashion industry, with strong demand for gold jewelry and watch parts. The company specializes in the design, prototyping and production of jewelry accessories, and has established long-term partnerships with many Swiss luxury watch manufacturers.
Since the purchase of its first SLM machine in 2014, Promotional SpA has been used3D printingTo produce gold and bronze models and related tools. After discovering that additive manufacturing can improve bracelet quality and reduce delivery time, the company went on to purchase a second system for printing pure gold, and then adopted its first DLP in 2019 3D printingThe machine uses liquid resin to make molds.
Embracing polymer-based AM, Promotion SpA is able to create custom tools with outstanding performance at every stage of the prototyping process. For example, the company’s laboratory testing tools are able to continuously evaluate numerous designs, and its polishing equipment is now smooth enough to function normally without being damaged too quickly.
Tiso explained: “Our products are highly customized and produced in small batches. This leads to frequent replacement of tools for assembly or polishing. Every bracelet undergoes very strict quality and mechanical tests, so we also need tools to simplify this. An important step.”

SpA’s new bracelet tool has 8mm “teeth” to align the bracelet during product testing. The image passes INTAMSYS.
Although Promotion SpA has extensive experience in the use of additional technologies, it has recently been using specific3D printingThere was a problem with the fixing device, which was used to align the links of the bracelet. The problem with the company’s existing tools is that they are made of polymers that are prone to photodegradation, so they can be easily damaged by excessive force.
In order to develop more resistant tools, Promotion SpA collaborated with FastParts, a subsidiary of Crea3D, who suggested that it switch to Nylon Carbon and INTAMSYS’s entry-level FUNMAT HT 3D printingmachine. Given that FFF machines are naturally much less than resin systems, engineers do have to remove some burrs during post-processing, but they do not need to make any major design changes.
The end of the final arm tool has precisely printed 0.8mm “teeth”, which proved to be able to quickly and easily align the bracelet based on the original 3D model. The final part measures 115×16.75×10 mm, which is also lighter than the previous part, while still showing the durability required to prevent further prototype manufacturing failures.company
It concluded: “We have never had the opportunity to use such a material, but its mechanical strength and lightness have left a deep impression on us. FastParts printed parts have withstood many cycles of fixing the lateral screws. Although the tool is loaded, but Will not bend in the middle.”
3D printingThe charm of jewelry
In recent years,3D printingThe huge accessibility of jewellery has caused a huge community of jewelry designers and manufacturers, and manufacturers continue to support them with new machines, software and materials. last year,3D printingOEM 3D Systems expanded the Figure 4 platform to the jewelry market. Once combined with the company’s jewelry castable materials and 3D Sprint software, the machine can produce castable parts with high precision and detail. Similarly, Gravotech sells its 3Design CAD/CAM software, a powerful engraving tool that can create the complex cutting paths needed to bring creative jewelry designs to life.
2017, Italy3D printingThe company DWS demonstrated the capabilities of its system for producing high-fidelity printed products by exhibiting a series of additively manufactured jewelry at CES. The company’s colorful rings and necklaces are designed as ready-made products for customers, and are made using its Irix Digital Stone nano-filled ceramics.
