树脂3D打印机最适合制作对细节要求极高、表面光滑的零件，例如桌面微缩模型、珠宝模具、牙科模型和精细原型。LONGER Orange系列树脂打印机采用MSLA（LCD）技术，利用高精度紫外光逐层固化液态树脂。
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.
是的。树脂打印机活动部件少，基本都是即插即用。搭配长效水洗树脂使用，可以简化后处理——你可以用水而不是异丙醇冲洗打印件，这大大降低了学习难度。
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.
