3D-ADD ACA1 , Air Cure Accelerator for photopolymer 3D resin Systems

Product Overview
3D-ADD ACA1 is an advanced reactive additive designed to accelerate and improve curing of 3D resin systems in ambient air.
It functions as an oxygen-tolerant air-cure accelerator, promoting complete surface hardening even without nitrogen or inert-gas protection.

ACA1 enhances curing rate and overall conversion, ensuring tack-free surfaces, uniform hardness, and consistent mechanical performance without affecting transparency, color, or shelf stability.
It is optimized for LED 385–405 nm curing systems and suitable for engineering, dental, bio-based, and circular 3D resin formulations.

Key Features & Benefits

• Air-tolerant accelerator – enables full curing in open-air conditions, no nitrogen purge required
• Faster and deeper cure – improves conversion and surface hardening under low-intensity LED light
• Non-yellowing and low-odor – maintains optical clarity and neutral appearance
• Low-toxicity – safe for dental, biomedical, and bio-based resins
• Improved surface hardness – reduces tack and incomplete top-layer cure
• Highly effective at low dosage – typical addition ≈ 2 % by weight
• LED-optimized – works efficiently with 385–405 nm SLA/DLP/LCD printers
• Universal compatibility – suitable for all common 3D resin systems, including circular and self-healing types

Recommended Applications
3D printing (SLA/DLP/MSLA): engineering, dental, and bio-based resins cured in air
Dental materials: light-curable restoratives, coatings, and adhesives
Bioprinting / Biomedical R&D: oxygen-tolerant, low-toxicity systems
Functional coatings: transparent or filled layers cured under ambient air
Circular & Self-Healing Resins: improves curing efficiency without disturbing dynamic networks

Compatibility

• Compatible with most LED-curable 3D resin systems.
• Synergistic with Fine Tuner FT1 or an alternative Fine Tuner accelerant
• Improves cure uniformity and surface quality without affecting viscosity, color, or post-process performance.
• No interference with coatings, fillers, or subsequent finishing steps.

Handling & Safety

• Appearance: clear, low-viscosity liquid
• Odor: none to faint
• Shelf life: 12 months unopened in dry, dark storage (< 25 °C)
• Avoid moisture and oxidizing materials
• Non-corrosive and non-flammable under normal use
• Not classified as CMR
• Consult MSDS before handling

Performance Highlights
Provides complete surface cure in air with LED 385 nm and 405 nm sources.
Delivers faster conversion and higher surface hardness throughout the print.
Improves gloss, uniformity, and durability of coatings and thin layers.
Eliminates the need for nitrogen purging, cover films, or prolonged post-curing.

Sustainability & Circular Integration
Optimized for low-energy LED curing, reducing power use and CO₂ footprint.
Removes inert-gas curing steps for lower environmental impact.
Compatible with Circular and Depolymerisable 3Dresyns
Ideal for bio-based and self-healing resin systems demanding transparency and safety.

Summary
3D-ADD ACA1 enables fast, uniform curing of 3D resin systems in ambient air, delivering reliable surface quality, full conversion, and consistent performance.
It is an essential Air Cure Accelerator for air-inhibited or slow-curing 3Dresyns, including Circular Bio, Self-Healing, and Low-Emission Resin Platforms.

Note: Ensure that your 3D resin contains enough Fine Tuner FT1 or an alternative Fine Tuner accelerant
