V650 Flex: Stratasys’ Reliable SLA Solution for Precise 3D Printing

When Stratasys unveiled its first commercial SLA printer, the industry was surprised. Known for pioneering PolyJet and FDM technology, the company now extends its expertise to stereolithography with the V650 Flex, delivering unparalleled precision and reliability.

Why Choose SLA?

SLA distinguishes itself from FDM and PolyJet by using a laser to cure thin layers of liquid resin. The result is extreme detail, flawless surface finishes, and one of the lowest cost‑per‑part rates in the market. SLA is the preferred choice for applications that demand high resolution and material versatility.

Primary SLA Applications:

• Highly transparent models and optical components
• Mold patterns for injection and compression molding
• Low‑ash burnout parts for metal casting
• Flexible, rubber‑like parts for automotive and consumer goods
• Biocompatible and dental components

V650 Flex Features

The V650 Flex offers a generous 20" x 20" x 23" build volume, an X/Y resolution of 0.0005" and a minimum layer thickness of 0.002". Its adjustable laser beam width ranges from 0.005" to 0.030", allowing operators to fine‑tune speed versus resolution. Unlike earlier Stratasys SLA lines, the V650 Flex is an open‑material platform: any 355 nm curable resin can be used, and four pre‑set material profiles—developed in partnership with DSM SOMOS—are available out of the box. Interchangeable vats and multiple vat sizes further optimize material usage and production efficiency.

Why Stratasys?

Designed by SLA experts for SLA professionals, the V650 Flex prioritizes reliability and user‑friendly operation. Although Stratasys is new to the commercial SLA market, the V650 Flex has already proven its industrial robustness in a 24/7, nonstop production environment at Stratasys Direct Manufacturing’s service bureau for the past four years.
