Sisma, an Italy-based developer of machinery and laser systems, debuted two new additive manufacturing systems at Formnext last week: the new EVEMET 200 laser metal fusion 3D printer series and the new EVERES VARIO DLP 3D printer. The company, which has primarily focused on the jewelry segment but also serves other industries, says the two product families were designed to “generate added value” for its customers.
The new EVEMET 200 series is described as a production solution that was built to meet the stringent requirements of the medical and industrial sectors. The powder bed fusion system is compatible with reactive metals and has a build volume of 200 x 200 mm. One of the more notable features of the EVEMET 200 series is that it is equipped with a powder loading tank with the capacity to hold 2.5 times the maximum printable volume of powder.
The new metal 3D printer series also comes with an updated gas flow management system inside the print chamber, which ensures that optimal density can be maintained across the entire work area without compromising the laser protection lens. Other features, like a dual, overlapping laser system, laser pulse management functions and a melt pool monitoring system allow users to achieve end-use quality and more efficient production.
The EVEMET 200 series is also defined by a pre-heated print plate (up to 200°C), two filter cartridges that each support up to 1000 hours of printing and an integrated suction system to seamlessly transfer residual powder from the construction cylinder to the recovery container. Sisma has also launched EVEMET MULTIPLO, an external powder management station for automatic sieving.
“EVEMET 3D printers are state-of-the-art production solutions, representing the most advanced technology on the market today for the production of three-dimensional metal artefacts,” Sisma said. “They guarantee the highest standards both in the monitoring of the process, where the operating parameters are displayed in progress and made available in a final summary, and in the monitoring of the melt pool, where the joint use of video cameras and software allow for instant verification of the quality of fusion and process stability.
The EVEMET 200 adds to Sisma’s existing portfolio of metal additive manufacturing systems, which fall under the MYSINT brand.
The EVERES VARIO is the third system in Sisma’s EVERES line, following the EVERES ZERO and EVERES UNO. The new DLP-based system has the highest resolution capacity (3840 x 2160 px) out of the three printers thanks to its 4K UHD light source. According to Sisma, the 3D printer has the “highest definition ever achieved” for a DLP resin system.
Users can play with the printer’s print volume and resolution, changing between a base of 115.2 x 64.8 mm suitable for very high resolution prints (30 µm) or a wider base of 226.6 x 127.4 mm for lower resolution (50 µm) but higher productivity. Both options have a tall maximum print height of 450 mm.
The EVERES VARIO, which bears the same distinctive shape as its predecessors, was designed for ease-of-use and depends on a simple LED right to communicate basic machine statuses to the user. A new retractable touch screen enables users a higher degree of control, with the ability to view the printing progress at any stage. Finally, the new 3D printer comes with a new double resin cartridge system and additional supply tank for improved productivity.
Features that have remained consistent along the EVERES printer family include self-alignment and self-reset functions for the Smart Building Platform (SBP), a durable resin tray with a bottom made of PTFE, high-speed printing enabled by patent-pending Zero Tilting Technology (ZTT), automatic loading and unloading of resin, an optional automated detachment system and a “Click & Make” software feature.
