Metal 3D Printer Handles Small Runs

EOS GmbH has introduced a new DMLS (direct metal laser sintering) additive manufacturing system called the EOS M 100. The company says that in terms of manufacturing process and parts quality, the EOS M 100 corresponds to its widely deployed EOS M 290 industrial metal 3D printing system. Additionally, the company describes the EOS M 100 system as being “the ideal choice for those considering an entry into additive manufacturing.”

The EOS M 100 offers a round build platform with a volume of 3.9 x 3.7 in. (100 x 95 mm). This small build volume, explains the company, enables users to focus on producing small part quantities cost-efficiently. By way of an example, the EOS M 100 can produce approximately 70 dental crowns and bridges in three hours, according to the company.

The EOS M 100 has a round build platform and a laser scan speed of up to 23 ft. per second (7.0 m/sec). Here, the platform holds 70 dental crowns and bridges made of EOS CobaltChrome SP2 that the EOS M 100 manufactured in approximately three hours. Image courtesy of EOS GmbH.

The EOS M 100 uses a 200-watt ytterbium fiber laser, which, due to its beam quality and performance stability, ensures optimum and consistent processing conditions, the company states, which adds that this results in reproducible part qualities. This feature, plus a 40-µm laser spot makes it possible to produce high-quality, highly complex and delicate components, says EOS. The system scans at speeds of up to 23 ft. per second (7.0 m/sec).

The EOS M 100 system currently processes EOS CobaltChrome SP2 (CE-certified, CE 0537) and EOS StainlessSteel 316L materials. EOS Titanium Ti64 is under development and will be the next material available for the system, according to the company.

The EOS M 100 has a modular interior structure that enables the system to be set up and dismantled quickly. Overall system dimensions are 31 x 37 x 89 in. (800 mm x 950 mm x 2,250 mm).

Other features of the EOS M 100 highlighted by its manufacturer include an efficient re-coating and exposure strategy that reduces non-productive time periods, easy replacement of materials and maintenance activities that can be performed quickly. The EOS M 100 supports a variety of software for DMLS manufacturing.

“The EOS M 100 adds to our portfolio of metal additive development systems and equipment. We have found the ease of material handling and component changeovers very beneficial. This has the potential to decrease setup times, increase productivity and improve operator safety and ergonomics,” said Michael Keane, manager of Technical Process Development at Boston Scientific, in an EOS-supplied testimonial.
