Overview of 3D-printer Sinterit Lisa

Printer description

Polish company Sinterit specializes in the production of 3D printers that use the technology of selective laser sintering (SLS-printing). This is a fairly new technology that has not yet had time to become widespread in the production of 3D printers, such as FDM, so the founders of the brand were able to occupy a vacant niche in the market. The company was founded in 2014, and as its main goal its management chose the production of the most technologically advanced, but at the same time available to a wide range of users devices.

IMPORTANT: Sinterit Lisa is one of today’s most advanced 3D printers based on the laser sintering technology.

The device works on the principle of plug-and-play, that is, in fact, the buyer receives a printer ready to print immediately after taking it out of the box without the need for time-consuming configuration. Simply plugging it in is enough.

Its distinctive feature is that the model allows you to print one large piece at a time, as well as several small ones, the flight of fancy of the owner can only be limited by the size of the printing table. It is also important that the printing technology allows for the manufacture of multiple parts, not only connect them to each other, but also to “put” into each other.
