SEPTEMBER 2018 Additive Manufacturing TECH REVIEW 36 Desktop SLS 3D Printer Expands Build Volume Expanding on the build size of the Lisa 1, the Sinterit Lisa 2 selective laser sinter- ing (SLS) desktop 3D printer is capable of manufacturing high-precision parts ranging to 32 cm (12.6"), without the need for supports. A nitrogen-filled build chamber supports the use of a range of materials, including strong and chemical-resis- tant plastics such as Nylon PA12 and Flexa Black, a TPU material for rubber-like applications. With the Lisa 2, the company is also introducing Flexa Grey with better flexibil- ity and PA11 with chemical and temperature resistance. Used with the Sinterit Sandblaster and Sieve, the Lisa 2 can be an end-to-end system for product development and production. The printer is suitable for prototypes and functional parts in industries such as automotive, elec- tronics and medical. Applications include turbines, pipes, electrical housings, tool handles, seals and more. 3D Printer Optimized for Reliable Operation in Existing Workflows The Ultimaker S5 3D printer is intended for profession- al users that require full geometrical freedom ca- pabilities, industrial-grade material properties, repeatability, high uptime and an integrated workflow to create functional prototypes, manufacturing tools and end-use parts. The 3D printer offers a 330 × 240 × 300-mm build volume for printing larger objects; dual extrusion; and a feeder system with a filament flow sensor that auto pauses and resumes when materials run out, preserving print quality. Enhanced bed leveling continuously compensates the print bed, en- abling unattended use. The 3D printer supports a range of materials from PLA to advanced engineering plastics such as nylon and PC. Compatibility with the Ultimaker App enables users to stay updated on the print's progress from a phone or tablet wherever they are.
