Additive Manufacturing technology from Cooksongold and EOS will change economics of making watch and jewellery products, by offering an affordable, compact, and design-driven manufacturing solution.

Cooksongold, a leading global supplier of precious metals for jewellery and watch-making, together with strategic partner 3D printer manufacturer EOS, has announced the launch of the PRECIOUS M 080 Direct Metal Laser Sintering (DMLS) system at the Hong Kong Jewellery and Gem Fair 2014.

The DMLS process builds the parts up layer by layer by melting and solidifying the fine precious metal powder using the energy of a focused laser beam. The PRECIOUS M 080 system is equipped with a 100-watt fibre laser, providing exceptional beam quality and power stability for high quality parts building. The system has a small spot size with excellent detail resolution, allowing the creation of even the finest structures.

The PRECIOUS M 080 is designed with a powder management process developed for the jewellery and watch-making industries. Its cartridge based system, which includes an extraction cartridge for easy removal of powder, enables quick metal changeover between jobs and materials.

The system has an 80 mm diameter round build platform with a working stroke of 95 mm (high, including building platform). The metal powders produced by Cooksongold have been optimised to match the performance of the Precious M 080 system. Currently the system can build parts using a variety of gold alloys and future development of additional materials to meet customer requirements is planned.

Dr. Adrian Keppler, Chief Marketing Officer (CMO) at EOS states: "This Additive Manufacturing (AM) process introduces an innovative and paradigm shifting technology to the luxury goods industry. With Cooksongold we found the perfect partner for the extension of our technology into this industry."

David Fletcher, European Product Manager at Cooksongold, explains: "Utilising the power of 3D CAD design, DMLS technology will challenge a designer's imagination and enable the creation of jewellery and watch components that previously would have been impossible to successfully manufacture."

"AM will change the economics of producing watch and jewellery products by offering a streamlined manufacturing process that dramatically reduces the time required from design conception to final part realisation. DMLS will also enable the production of design-driven pieces that are not limited by the restrictions of conventional production techniques such as lost wax casting, eliminating many process steps and costs that we normally encounter."

Cooksongold, part of the Heimerle + Meule Group, is a leading supplier of fabricated precious metals in Europe, a supplier of gold, silver, platinum and palladium alloys, wire, sheet, tubing, coin blanks and casting grain. Cooksongold will provide clients with detailed training packages for PRECIOUS M 080 machine operation. A copy of the design guidelines can be accessed via the Cooksongold DMLS website.

Richard Hoptroff, based in London, was the first watch maker to produce an atomic watch and is convinced that DMLS technology offers him the best production solution available. "Critically for our enterprise, industrial 3D printing keeps batch sizes down," he says. "You can change the design quickly and create complicated shapes that would be otherwise impossible."

Height 11.6mm

Weight as built 40.8g, weight as finished milled and polished 34.1g

Time from design finalisation to finished part - 1 week

Johannes von Stumm, designer of the puzzle rings, explained why he wanted his designs 3D printed in gold rather than using traditional lost wax casting. "I create many different iterations of the same design and the ability to change and immediately print a piece offers me great flexibility. With DMLS I send over my latest design which is simply printed and ready to polish. I am even able to send multiple files and have them printed together to save cost."

hi, i'm goldsmith, and i am planning to start jewelry customisation for my customer after knowing Precious M 080, i would like to check with you on costing. please reply on my email, I also find very doubtful when non of your contact stated in your website. It makes me feel like this machine is only at concept stage, the technology does not exist.
