Get ready for some exciting insights into the world of 3D printing as we explore Essentium’s HTN (High-Temperature Nylon), a material that’s making waves in the industry. HTN, a polyamide-based chemistry, offers incredible mechanical and thermal properties, making it a game-changer for various applications.
Material Marvel: Essentium’s HTN
Essentium’s HTN is not your run-of-the-mill nylon. It boasts improved mechanical and thermal properties, setting it apart from standard nylons. But that’s not all; it’s remarkably easy to print with minimal warping tendencies, exceptional toughness, and impressive wear resistance. In fact, it’s often considered a drop-in replacement for Delrin, the sought-after material in machine shops.
One of the standout features of HTN is its excellent resistance to moisture absorption. You won’t need to worry about drying it between prints, thanks to its best-in-class low moisture absorption characteristics.
Applications Galore
HTN opens up a world of possibilities with its fantastic heat deflection temperature, superior printability compared to ABS and standard nylon, exceptional toughness, and resistance to chemicals and solvents. This makes it ideal for various applications, including:
- Jigs and fixtures
- Electrically insulating components
- Electrical housings
- Low-speed gears and moving parts
While it excels in multiple sectors, the most significant difference from regular nylon is HTN’s specific design to replace Delrin (POM or acetal) – a material frequently requested in machine shops.
Printing Conditions
To unlock the full potential of HTN, you’ll need a 3D printer with specific capabilities:
- Nozzle temperature of at least 270°C (preferably 290-300°C)
- Bed temperature ranging from 70-80°C
- Printing speeds of 20-60 mm/s
For adhesive, better nanopolymer adhesive works wonders, whether your build surface is glass, carbon fiber, PEI, or other materials. A chamber temperature of 70°C or higher is highly recommended, although HTN can be printed in an open-air printer.
For supports, consider materials like Aqua Tech X1, Aqua SysT 120, or Alcasys 180 if you have them on hand.
Test Results and Strength
Let’s dive into some key material specifications:
- Tensile strength: Approximately 76 MPa
- Flexural strength: Around 129 MPa
- Notched Izod impact strength: Approximately 3.4 kJ/m²
HTN’s data sheets and more details are available at our online store.
When it comes to breaking and burning, HTN delivers impressive results. It exhibits structural rigidity and excellent layer fusion, providing reliable, consistent parts. It’s robust, even in the face of open flame tests.
Essentium’s HTN: The Future of 3D Printing
Essentium’s HTN is a game-changing material, and we couldn’t be more excited about its potential. The combination of excellent mechanical properties, superior heat resistance, and ease of use makes it a top choice for demanding applications.
If you’re looking for a Delrin replacement or a high-performance material for your projects, HTN should be at the top of your list. It’s time to embrace the future of 3D printing with Essentium’s HTN.
