HONG YE SILICONE liquid silicone for 3D Printing, mainly the HY-6 series, is a high-precision Addition Curing Silicone (platinum cure) tailored for advanced 3D printing and mold making applications. As a high-quality Platinum cured mold silicone and liquid silicone, it has ultra-low viscosity, excellent self-deaeration, and remarkable thermal stability. This two-component RTV 2 Silicone Rubber achieves precise detail replication, strong durability, and good compatibility with polyester resins and concretes. With optional FDA food-grade certification, it provides reliable, bubble-free performance for global B2B buyers in additive manufacturing, rapid prototyping, and precision casting industries.
Product Overview
Our Liquid Silicone for 3D Printing is a professional addition cure silicone developed to meet the strict requirements of 3D printing and high-precision replication tasks. As a high-grade Liquid Mold Silicone and Rapid prototyping silicone, it can cure at room temperature or elevated temperatures, with excellent flowability to capture even the finest details of 3D models. Compared with ordinary tin-cure silicones, this platinum-cure formula has better inhibition resistance, higher thermal conductivity, and longer-term stability, making it suitable for 3D printing master patterns, complex molds, and high-temperature casting scenarios.

Product Features & Advantages
Ultra-low viscosity and excellent flowability ensure that the finest details and complex patterns of 3D models are perfectly replicated. Outstanding self-deaeration performance effectively eliminates air bubbles, reducing the need for post-processing and improving production efficiency. Excellent thermal resistance (-65°C to 350°C) and high thermal conductivity make it applicable to various high-temperature 3D printing processes. High tear strength and low shrinkage (<0.1% for platinum cure type) ensure that the molds are durable and precise, supporting multiple replication cycles. Good resistance to inhibition, polyester resins, and concrete prolongs the service life of the molds. Non-oily and non-sticky formula with excellent release properties makes demolding easy and avoids damage to the finished products. The platinum cure variant with FDA certification is non-toxic and odorless, 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 to ensure the surface is smooth. Step 2: Take the HY-6 series silicone base and curing agent, and measure them 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 good self-deaeration performance can further reduce bubble formation. Step 4: Pour the mixed liquid silicone into the 3D printing system or mold frame, and let it flow naturally to fill all details of the model. Step 5: Cure at room temperature, or heat appropriately to speed up vulcanization; the silicone can be used after it is completely solidified.
Application Scenarios
It is ideal for making 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 well in soap, candle, and food-grade mold making (with FDA certification). It provides reliable solutions for rapid prototyping, industrial manufacturing, and custom craft production, helping buyers improve product precision, reduce production costs, and enhance production efficiency.
