Why San Draw Stands Out?
San Draw offers the Most Cost-Effective and High-Precision Silicone 3D Printing Solution.
In a market where similar machines and materials are widely available, San Draw sets itself apart with unique advantages and industry-leading affordability. Since 2014, San Draw has pioneered innovation in silicone 3D printing with its patented FAM (Fluid Additive Manufacturing) technology, delivering highly accurate, stable, and reliable results tailored for advanced applications.
Unlike traditional methods, San Draw develops and manufactures its own 1-part and 2-part silicone materials, specifically optimized for 3D printing. These biocompatible silicones are widely used in academic research, medical prototyping, and commercial production, ensuring both material safety and printing performance.
This article highlights why San Draw's silicone 3D printers and materials continue to lead the market, not just in technical capability, but also in total cost efficiency. Below, we break down the core advantages of our printing technology and custom-engineered silicone formulations.
Choosing Between One-Part and Two-Part Silicone: A Trade-Off Between Curing Speed and Maintenance Cost
One-part silicone offers softer material options but tends to cure too quickly, often leading to nozzle clogging during printing. In contrast, two-part silicone allows for more stable printing with heat-assisted curing, but the need for heating systems also increases equipment complexity, long-term maintenance, and overall cost.
San Draw’s Breakthrough: Stable Stacking of Liquid Silicone at Room Temperature: No Heating Required!
A key innovation from San Draw lies in our room-temperature printable two-part silicone. Unlike traditional materials that require heating to hold their shape, our specially formulated silicone remains in liquid form yet stacks reliably during printing, without collapsing. This eliminates the need for external heating devices while still delivering high-precision results, significantly simplifying the printing process and lowering equipment and maintenance costs.
This material advancement offers several key benefits:
No Nozzle Clogging – Curing behavior is optimized to flow smoothly without rapid solidification, ensuring reliable extrusion.
High Precision Without Heating Systems – Achieves exceptional accuracy without relying on heating modules, simplifying the hardware and reducing operational complexity.
Low Maintenance, Lower Manufacturing Cost – By removing the need for heating systems, San Draw reduces equipment cost and post-sale maintenance, delivering premium printing quality at an accessible price.
Versatile for Advanced Applications – Ideal for printing medical-grade components, prosthetics, dental models, and other detailed structures requiring consistent shape retention and fine resolution.
Mechanical properties of silicone? What equipment can be used?
“Crafting Tailored Solutions That Truly Understand and Empower Our Users”
SanDraw’s two-part silicone provides a stable and efficient 3D printing experience with the #Widest hardness range, from Shore A20 to Shore A70.
It’s ideal for manufacturing durable parts, seals, and components for soft robotics. The oven curing process improves print stability, especially for larger or more complex models, while greatly minimizing nozzle clogging issues during printing.
All San Draw machines from model S180 and above (S180, S300, S400) are compatible with all San Draw silicone materials and support printing with water-soluble support materials.
What Sets San Draw Apart: True 100% Pure Silicone for 3D Printing
Not Just “Pure Silicone” — But 100% Pure Silicone Raw Material
Most silicone 3D printing materials on the market are actually photocurable silicone resins, a type of UV-curing polymer that mimics silicone after printing but is NOT truly made from 100% silicone. These materials are often marketed as "pure silicone" because the final printed object resembles silicone in softness and appearance.
However, San Draw uses real 100% pure silicone as the printing material, meaning our liquid silicone contains no added resins, fillers, or acrylate components. This distinction is critical when it comes to performance and material integrity.
Superior Mechanical Properties for Demanding Applications
Thanks to our 100% pure silicone formulation, our printed parts offer:
Exceptional elasticity and rebound performance
High tear and tensile strength
Excellent biocompatibility (ISO 10993 certified)
Long-term stability in medical and engineering use
These qualities make San Draw silicone ideal for applications such as:
Soft robotics and robotic arms
Medical devices and prosthetics
Wearable sensors and flexible electronics
Why This Matters for Engineers and Researchers?
Using true silicone, not just a resin approximation, means your prototypes and end-use parts will behave as real silicone elastomers, with consistent and predictable performance. You get accurate material simulation, better durability, and compatibility with real-world product development.
Our 100% pure silicone delivers not only reliable rebound behavior but also the physical accuracy needed for motion control, medical simulation, and mechanical prototyping.
