FAQ
A resin 3D printer is best for parts that demand extremely fine detail and smooth surfaces, such as tabletop miniatures, jewelry molds, dental models, and detailed prototypes. LONGER Orange series resin printers use MSLA (LCD) technology to cure liquid resin layer by layer with high-precision UV light.
The Orange 4K features a 4K monochrome LCD for the sharpest detail and fastest curing, making it the flagship choice. The Orange 30 offers a larger build area for bigger models, while the compact Orange 10 is an affordable entry point for beginners and small parts.
Yes. Resin printers have few moving parts and are largely plug-and-play. Pair one with LONGER water washable resin to simplify post-processing — you can rinse prints with water instead of isopropyl alcohol, which makes the learning curve much friendlier.
LONGER resin printers work with standard 405nm UV-curable resin, including LONGER’s own Standard UV Resin and Water Washable Resin. Third-party 405nm resins are also compatible, giving you flexibility on price, color, and material properties.
After printing, wash off uncured resin (with water for water washable resin, or IPA for standard resin), then fully cure the model under UV light. A wash & cure machine automates both steps and delivers consistent, professional results.
Yes, with basic precautions: wear nitrile gloves when handling liquid resin, work in a ventilated space, and keep resin away from children and pets. Cured resin parts are safe to handle normally.
MSLA resin printers routinely produce layer heights of 0.05mm or finer, capturing details that FDM printers simply cannot reproduce — ideal for miniatures with facial features, textures, and fine lettering.
FEP film is a consumable that typically lasts dozens of prints before clouding or scratching; the monochrome LCD screens in the Orange series are rated for roughly 2,000 hours of use. LONGER stocks genuine replacement FEP films and screens for all Orange models.
Choose resin if you need fine detail and smooth surfaces (miniatures, jewelry, dental). Choose FDM if you need larger, stronger functional parts at low material cost. Many makers eventually own both.
LONGER’s official store stocks FEP release films, mono and LCD screens, and touch screens for the Orange 4K, Orange 30, and Orange 10, so your printer stays productive for years.
