3D printing UV/LCD standard grey resin 1 L Flashforge 405nm

Flashforge 3D printing UV/LCD standard grey resin 1 L is a general-purpose photopolymer formulated for use with 405 nm desktop UV/LCD 3D printers. The one‑liter bottle provides sufficient material for multiple prototype prints, model parts and functional components. The resin cures consistently under 405 nm light, producing medium-strength parts with a smooth grey surface finish suitable for post-processing such as sanding and painting. Handle and post-cure according to safety guidelines to achieve optimal mechanical properties and dimensional stability.

Advantages

This Flashforge standard grey resin offers predictable layer curing behavior and stable viscosity for reliable printability on most 405 nm LCD and UV MSLA printers. The grey shade improves visibility of fine details and layer lines, aiding inspection and post‑processing. Parts exhibit good surface detail fidelity and are compatible with common finishing techniques. The 1 L pack size reduces the need for frequent refills and is convenient for small workshops and rapid prototyping workflows.

Suitable for

• Prototyping and concept models
• Scale models and miniatures
• Functional parts and assembly test pieces
• Visual samples and display components

Key specifications

• Photopolymer type: UV/LCD resin formulated for 405 nm wavelength
• Color: standard grey
• Volume: 1 liter
• Compatibility: desktop UV/LCD (MSLA) 3D printers that use 405 nm curing light
• Typical properties: medium strength, good surface detail, sandable and paintable
• Storage: store in a cool, dark place away from direct sunlight

How to use

Pour the resin into the printer’s vat following the printer manufacturer’s instructions and ensure the vat and build plate are clean before starting a print. Use slicer settings recommended for standard grey resins with a 405 nm light source; typical layer exposure and lift speeds depend on your printer and model geometry. After printing, remove the part carefully, drain excess resin, and clean with isopropyl alcohol or a suitable solvent. Post-cure parts under a controlled 405 nm light source or UV chamber to reach final mechanical properties and dimensional stability.

Recommendations

Wear nitrile gloves and eye protection when handling uncured resin, work in a well‑ventilated area, and dispose of resin waste in accordance with local regulations. Shake or gently roll the bottle before use to ensure uniform pigment and formulation. Allow freshly printed parts to fully post‑cure for consistent strength and to minimize residual tackiness.
