ADDITIVE MANUFACTURING
EOS presented removable partial dentures at this year’s International Dental Show (IDS), Cologne, Germany, in March. ‘Compared to the conventional approaches that have been used up to now to produce removable partial dentures, clear competitive advantages can be achieved using AM,’ said Martin Bullemer, business development manager medical at EOS. ‘Digitally manufactured partial dentures have been tested with pilot customers. The feedback has been very positive, encouraging us to continue to develop and optimize the application.’ During a pilot phase, dental laboratory Flussfisch GmbH produced partial dentures based on direct metal laser sintering (DMLS) technology from EOS. ‘Digitally manufactured dental prostheses have consistent tolerances and quality as well as reproducible properties and at the same time are very accurate, allowing a good fit,’ said Michaela Flussfisch, MD of Flussfisch GmbH. EOS’ metal system EOSINT M 270 Dental is used for manufacturing of removable partial dentures using CE-certified material EOS CobaltChrome RPD. During the additive manufacturing process, the fine powder particles ensure

a fine-grain structure so that a digitally produced dental prosthesis has much higher strength and fatigue resistance than a casting. Additionally, the risk of a clamp breakage is reduced compared to a conventional cast model, EOS says. The finished products comply with the relevant standards EN 1641 and EN ISO 22674.
Entry-level AM EOS also presented the smaller EOS M 100 system for the first time at IDS. The
system provides the dental industry with an entry-level AM system based on metal technology. With its small build volume and 100 mm diameter circular platform, dental laboratories can now manufacture high quality crowns and bridges from EOS CobaltChrome SP2. The system is equipped with a 200 W fiber laser and has high power stability as well as constant processing conditions to produce better components. EOS; www.eos.info
Aequs reinforces aerospace/3D printing alliance Aerospace manufacturer Aequs has made a minority equity investment in the Farinia Group’s Spartacus3D, a French company specializing in additive layer manufacturing (ALM). ‘As cutting-edge manufacturing technology, ALM offers tremendous potential for creating new manufacturing capabilities and economies of scale and scope,’ said Aravind Melligeri, chairman and CEO of Aequs. ‘ALM’s potential for reducing the cost of production changeovers and customization and for increasing the variety of products each unit of capital can produce, makes it a compelling innovation for the aerospace and defense (A&D) industry, which in contrast to other industries, is more reliant upon low volume production.’
Supply chain The aim of the partnership is to give A&D industry customers new supply chain

options unavailable elsewhere. ‘We expect our partnership to advance the state-ofthe-art in aerospace manufacturing and produce higher levels of customer customization, on-demand responsiveness, and
product complexity at competitive costs,’ said Fre´de´ric Guinot, CEO of Farinia Group. Safran, the French-based international leader in aerospace, defense and security, welcomed the partnership. ‘We are very interested in the collaboration between Aequs and Farinia on Spartacus3D, because of its potential for producing enhanced manufacturing capabilities and favourable supply chain economics,’ said Xavier Dessemond, vice president of purchasing for Safran. This is not the first partnership between Farinia and Aequs. Aequs and Farinia already operate the SQuAD Forging Private Limited joint-venture together with Aubert & Duval as part of the Aequs precision engineering ecosystem located inside the Aequs Special Economic Zone (SEZ) in Belagavi, Karnataka.
