Welcome back to the world of 3D printing! Today, we’re taking a closer look at Sentra’s PA12 Smooth material. If you’re a 3D printing enthusiast or professional, this versatile nylon 12 polymer is a game-changer. Designed for use on Sentra’s Lisa and Nils SLS 3D printers, PA12 Smooth offers a wide range of applications, exceptional quality, and more. Let’s dive into why this material is a popular choice for both prototyping and end-use parts.
The Power of PA12 Smooth
PA12 Smooth gets its name from its outstanding characteristics. It’s no ordinary material; it’s a nylon 12 polymer developed in collaboration with BASF, ensuring top-notch quality. But what sets it apart and why should you consider using it for your 3D printing projects?
This material is primarily known for its versatility and affordability. Here’s where it truly shines:
- Prototyping and End-Use Parts: PA12 Smooth is the go-to choice for prototyping and creating functional end-use parts. It’s a second-generation material, celebrated for its low cost, minimal warping, and exceptional detail quality.
- Minimal Powder Refresh: Compared to other materials, PA12 Smooth boasts a low refresh ratio of just 22%. This means you only need to add 22% new powder to the existing batch, making it highly economical and environmentally friendly. The software takes care of the mixing process seamlessly.
- Quality to Price Ratio: You’ll appreciate the exceptional quality this material offers relative to its cost. It’s a cost-effective solution for a wide range of applications.
- Smooth Surface Finish: PA12 Smooth delivers a smooth print surface, ensuring your 3D prints look polished and professional.
- Rigidity and Strength: While not as robust as PA-11, this material exhibits great rigidity and strength, suitable for a variety of projects.
- Chemical Resistance: Thanks to its nylon 12 composition, PA12 Smooth offers high resistance to chemicals, ensuring your parts can withstand challenging environments.
Applications for PA12 Smooth are vast. You can use it to create gears, bearings, brackets, structural parts, enclosures for electronics, and components with thin walls. The material’s flexibility and strength make it suitable for crafting Jigs, fixtures, and tooling for various machining processes. Additionally, you can explore watertight applications, although post-sealing may be recommended in some cases.
The Magic of SLS 3D Printing
SLS (Selective Laser Sintering) 3D printing technology offers a range of advantages that make it stand out. When you choose SLS, you benefit from:
- No Support Structures: Unlike some other 3D printing methods, SLS eliminates the need for support structures. This not only saves you time and material but also opens up a world of design possibilities.
- Endless Geometry Options: With no support structures to worry about, your design options become virtually limitless. You can create complex and intricate geometries without constraints.
- Near Isotropic Parts: SLS produces near-isotropic parts, meaning they are strong in every direction. Unlike FDM (Fused Deposition Modeling) printing, where layer adhesion can be a limitation, SLS parts exhibit consistent strength throughout.
SLS technology, combined with PA12 Smooth, empowers you to bring your creative visions to life with precision and without the hassle of support structures.
Compatibility and Technical Specifications
Now, let’s address compatibility. PA12 Smooth doesn’t require a nitrogen or inert gas environment during printing, making it a convenient choice for SLS 3D printing. It’s compatible with Sentra’s Lisa and Nils lineup of 3D printers, giving you a wide range of options for your projects.
For those who love delving into the technical details, here’s a quick rundown of the material’s specifications:
- Shore Hardness: PA12 Smooth boasts a Shore hardness of 74D, classifying it as an extra-hard material with impressive rigidity.
- Melting Point: The material’s melting point is around 185°C.
- Refresh Ratio: As mentioned earlier, the refresh ratio is a mere 22%, allowing for efficient powder reuse.
- Strength: PA12 Smooth exhibits a tensile strength of 32 megapascals, making it a reliable choice for various applications.
- Modulus: The potential modulus of this material is 1470, reflecting its strength and stability.
- Flexural Modulus: It has a flexural modulus of 1160 MPA, showcasing its ability to withstand mechanical stress.
- Elongation at Break: With an elongation at break of 10%, this material offers a balance of strength and flexibility.
- Impact Strength: Using the Sharpie method, PA12 Smooth achieves an impact strength of 16 kilojoules per square meter. These technical specifications ensure reliable performance and quality in your 3D prints.
