The Formlabs Clear Resin V4.1 in the 1.000 L cartridge is a high-quality, transparent formulation specifically engineered for the Form 3 and Form 3+ printers. This resin combines the optical clarity of glass with mechanical properties similar to tough ABS plastic. It offers excellent hardness along with slight flexibility, making it highly resistant to breakage. The resolution is extremely fine, allowing for the printing of intricate details and smooth surfaces. This material is ideal for applications requiring both transparency and durability, such as functional prototypes, light pipes, engineering enclosures, detailed miniatures, and dental and jewelry models where clarity and precision are paramount. Post-processing requires washing in isopropyl alcohol to remove excess resin, followed by UV curing (405 nm) to maximize mechanical properties and ensure complete polymerization. To achieve optimal optical clarity, models can be sanded, polished, or coated with a clear gloss. Safety notes: Always wear nitrile gloves, safety glasses, and work in a well-ventilated area, as the resin can cause skin and eye irritation.
