HONG YE SILICONE liquid silicone for 3D Printing, mainly the HY-6 series, is a high-precision Addition Curing Silicone (platinum cure) designed specifically for advanced 3D printing and mold replication applications. As a quality Platinum cured mold silicone and liquid silicone, it possesses ultra-low viscosity, excellent self-deaeration, and superior thermal stability. This two-component RTV 2 Silicone Rubber ensures precise detail reproduction, durable performance, and great compatibility with polyester resins and concretes. With optional FDA food-grade certification, it delivers consistent, bubble-free results for global B2B buyers in additive manufacturing, rapid prototyping, and precision casting fields.
Product Overview
Our Liquid Silicone for 3D Printing is a professional addition cure silicone tailored to meet the rigorous demands of 3D printing and high-precision replication work. As a reliable Liquid Mold Silicone and Rapid prototyping silicone, it can cure at room temperature or under heated conditions, boasting excellent flowability that captures even the most delicate details of 3D models. Unlike ordinary tin-cure silicones, this platinum-cure formula offers stronger inhibition resistance, higher thermal conductivity, and more stable long-term performance, making it ideal for 3D printing master patterns, intricate molds, and high-temperature casting scenarios.

Product Features & Advantages
Ultra-low viscosity and excellent flowability ensure accurate replication of the finest details and complex patterns of 3D models. Exceptional self-deaeration effectively eliminates air bubbles, reducing post-processing workload and boosting production efficiency. Outstanding thermal resistance (-65°C to 350°C) and high thermal conductivity make it suitable for various high-temperature 3D printing processes. High tear strength and low shrinkage (<0.1% for platinum cure type) ensure durable, precise molds that support multiple replication cycles. Strong resistance to inhibition, polyester resins, and concrete extends mold service life. Non-oily, non-sticky formula with excellent release properties enables easy demolding and prevents damage to finished products. The platinum cure variant with FDA certification is non-toxic, odorless, and suitable for food-contact mold making.
Core Operation Steps
Step 1: Prepare the 3D printing master model, clean it thoroughly to remove dust, oil stains and other impurities, ensuring a clean and smooth surface. Step 2: Measure the HY-6 series silicone base and curing agent according to the recommended ratio (usually 1:1 for addition cure silicone). Step 3: Mix the two components evenly in one direction to minimize air bubbles, and the product’s excellent self-deaeration performance further eliminates residual bubbles. Step 4: Pour the mixed liquid silicone into the 3D printing system or mold frame, allowing it to flow naturally to fill all details of the model. Step 5: Cure at room temperature, or apply appropriate heat to accelerate vulcanization; the silicone is ready for use once fully solidified.
Application Scenarios
It is ideal for creating 3D printing master patterns and precision molds. Suitable for replicating complex art crafts, architectural components, garden ornaments, jewelry, and high-precision prototypes. Compatible with a variety of casting materials, including polyester resin, PU, PVC, gypsum, plaster, concrete, stone, GRC, wax, and jewelry materials. It performs excellently in soap, candle, and food-grade mold making (with FDA certification). It provides stable solutions for rapid prototyping, industrial manufacturing, and custom craft production, helping buyers improve product precision, reduce production costs, and enhance work efficiency.
