3Dresyn LA1 Liquid Amber for direct 3D printing of Amber Jewelry

3Dresyn® LA1 Liquid Amber is a natural amber-filled photopolymer designed for direct 3D printing of amber-like jewelry, providing a characteristic satin amber finish with high aesthetic quality and material consistency.

Designed for use in SLA, DLP and LCD vat photopolymerization systems within controlled professional environments. Suitable for direct manufacturing of decorative and wearable components requiring amber-like appearance, high detail and good mechanical durability.

• Rings, pendants, earrings, bracelets, charms and beads
• Amber-like decorative jewelry components
• Fashion hardware and accessories
• Design prototypes and final wearable parts

• Tensile strength: <50 MPa (ISO 527)

• Typical layer thickness: 25–100 μm (recommended 50 μm for fine jewelry detail)
• Supports: fine contact points recommended on visible surfaces
• Cleaning: short, efficient wash; avoid prolonged solvent exposure
• Finishing: suitable for wet sanding and polishing to achieve mirror finish or matte textures
• Formulated to support extended resin tank durability

Material performance depends on printer type, exposure conditions, geometry, post-processing and finishing workflow. Optical appearance, surface quality and mechanical behavior must be validated by the user for each specific application.

• Authentic amber-like appearance with natural amber content
• Direct 3D printing of finished jewelry pieces
• High mechanical strength suitable for wearable parts
• Excellent surface detail and polishability
• Durable with good scratch and wear resistance
• Very low shrinkage and high dimensional stability
• Compatible with most SLA, DLP and LCD systems

This material is supplied as a professional manufacturing material and is not marketed as a finished product. It is not certified as a medical device or implant. Final performance, skin compatibility and application suitability remain the responsibility of the user.
