Formnext wraps up today, and it’s been a packed four days, with lots of new 3D printers and announcements of collaborations and partnerships that intend to advance additive manufacturing technology. Among the new 3D printers are two from Sisma, an Italian company that has been building laser systems and machinery since 1961. The Everes Zero and Everes Uno are DLP 3D printers designed to cater to several markets, including dental, medical and industrial production.

Both 3D printers features Sisma’s patent pending Zero Tilting Technology (ZTT). During the print job, the vat is fixed in the printer while the glass tilts after each layer, avoiding the suction effect and subsequent mechanical stress. A Smart Build Platform (SBP), also patent pending, self-aligns and self-zeroes after every print and features an automatic detachment function that reduces the risk of damaging prints. The bottom of the vat is made from PTFE, an inert material that allows for non-degenerative 3D printing and high dimensional precision, along with high repeatability and reliability. The resin cartridges are automatically recognized by RFID tags, allowing for automatic loading and unloading.

The Everes Zero and Everes Uno come with user-friendly “Click and Make” software for a 3D printing process that is easy, streamlined and highly automated. Ease of use is one of Sisma’s prime goals for these two new 3D printers, and its many automated features minimize the necessity of manual intervention while maintaining a focus on high quality prints.

A few specifications for the Everes Zero:

  • Build volume: 96 x 54 x 200 mm
  • Dimensions: 411 x 970 x 272 mm
  • XY pixel resolution: 50 micrometers
  • Layer thickness: 10 to 200 micrometers
  • Print speed: up to 6 cm per minute

Specifications for the Everes Uno:

  • Build volume: 124.8 x 70.2 x 200 mm
  • Dimensions: 411 x 970 x 272 mm
  • XY pixel resolution: 65 micrometers
  • Layer thickness: 10 to 200 micrometers
  • Print speed: up to 6 cm per minute

Sisma offers several resins that are compatible with both new 3D printers. Resin One is designed for exceptional surface quality, while Spritz ABS offers high precision well-suited for industrial applications in particular. Dental Model is formulated for high resolution, precision, and smooth surface finish for dental molding, and Green Cast is an extremely high-precision resin aimed at jewelry 3D printing. Grey Master is an especially hard resin designed for prototyping and functional parts.

Sisma, in its early days, produced machinery for the automatic production of gold chains for the jewelry industry. It has since come a long way, now encompassing production solutions for marking, welding, cutting, engraving and additive manufacturing. The company began using laser technology in 2001, and entered the additive manufacturing market in 2014. In addition to SLA/DLP technology, Sisma offers a larger range of Laser Metal Fusion 3D printers directed at the jewelry, medical, dental and industrial markets.

Formnext may be finishing up today, but you can still pay Sisma a visit if you’re there and take a look at its new 3D printers. Stop by and see the company at Booth C11 in Hall 3.0.
