The vast majority of desktop FDM machines lack the finish and resolution for professional-grade output. Until now, the resources and floor space required kept professional SLA printers far out of reach for the individual designer.
In our stereolithography (SLA) process, a precise system directs a laser across a tray of liquid resin and causes a thin layer to solidify. This chemical reaction allows for the creation of printed parts that are:
- watertight - Formlabs printers create sealed surfaces. FDM printers fuse together sections of filament, which can leave microscopic gaps.
- isotropic - Formlabs printers are capable of producing parts with consistent material properties along the X, Y, and Z axes.
- detailed - The resolution possible with Form 2 printers makes them appropriate for applications that require fine detail, like dentistry and jewelry.
