Formlabs Clear Cast Resin in the 1-liter bottle, specifically engineered for the Form 3, is a high-performance UV-curing resin with Tough-ABS-like properties. This material stands out for its exceptional clarity and transparency, making it ideal for applications requiring optical precision. Its mechanical properties offer a balanced mix of hardness and flexibility, ensuring printed parts are resistant to breakage, similar to standard ABS. Thanks to the high detail resolution of Form 3 printer technology, the finest structures and complex geometries can be reproduced accurately. Post-processing with UV light (e.g., in a Formlabs Cure Station) is required after printing to achieve the final mechanical properties. The resin is excellent for technical prototypes, functional testing, as well as model railroading and dioramas where clear windows or smooth surfaces are needed. It is also suitable for dental applications like transparent aligners or jewelry for clear inlays. Safety is a top priority: wear nitrile gloves and safety glasses during handling, as the resin can irritate skin and eyes. Always work in a well-ventilated area to avoid fumes. Post-processing involves removing support structures and washing in isopropyl alcohol to eliminate residual resin.
