Today, we’re delving into the world of high-temperature 3D printing with PSU Polyphenylsulfone (PSU), a remarkable filament from 3DX Tech. PSU boasts exceptional heat resistance, sterilization capacity, and chemical toughness, making it a fantastic choice for various industries. Let’s explore this impressive filament.
Introducing PSU Polyphenylsulfone
PSU, or Polyphenylsulfone, is an outstanding high-temperature filament. Its superb heat resistance and chemical resilience make it a sought-after material across multiple industries. When you purchase PSU from Vision Miner, you receive it in a vacuum-sealed bag, ensuring its quality. Remember, you must dry it before first use, so don’t worry if the bag isn’t sealed upon arrival.
Why choose Vision Miner? Simple, you get three percent back on every dollar you spend, which can be used for various 3D printing needs, including nozzles, spools, machines, accessories, and more. Plus, our team is here to assist you when you need support.
Applications in Various Industries
PSU finds applications in a wide range of industries. In the medical field, it’s used for medical instrument components, manifolds, medical trays, autoclavable instruments, connectors, and coil bodies. In the automotive sector, PSU serves in oil level indicators, valve spools, flanges, tubes, pump cases, and inspection windows. Its chemical resistance and high-temperature stability make it a top choice in these applications.
Printing with PSU
When printing with PSU, you’ll need a nozzle temperature of at least 360°C, with a typical range of 360°C to 390°C. The print bed temperature is around 160°C, but it can be as low as 120°C. Nanobot Armor adhesive works well to keep your print secured on the bed. A heated chamber is recommended for successful printing with PSU, although not mandatory. A heated chamber helps prevent warping and ensures a better print for larger, thicker parts.
Handling Moisture and Drying
As with many 3D printing filaments, drying PSU is crucial. Even brand-new spools need to be dried before use. Vision Miner offers a comprehensive drying kit, including vacuum chambers and ovens, for efficient moisture removal. This kit is available on our website.
Material Specifications
PSU exhibits impressive material specifications, including a heat deflection temperature of 172°C and a glass transition temperature of 187°C. It’s an amorphous thermoplastic and can be annealed for added part strength. The tensile strength is approximately 52 megapascals. Remember that the part’s design and orientation during printing can affect its strength.
Environmental Factors
PSU offers fair resistance to UV exposure, but extended sun exposure may cause some weathering. It excels in hydrolytic resistance and is used in steam and hot water applications, making it suitable for the food industry. PSU is also highly chemically resistant to various substances, including gasoline, oil, alcohols, and hydrochloric acid. However, it’s not recommended for use with chlorine or sulfuric acid.
Electrical Properties and Sterilization
PSU is a highly resistive material, making it an excellent insulator with a dielectric constant of 3.18 and a dissipation factor of 0.113. While PSU is not certified as biocompatible, it’s often used in the food industry for applications involving steam and high temperatures. It can be autoclaved and sterilized for various uses.
Testing and Use Cases
We’ve conducted several tests on PSU to understand its properties better. We’ve demonstrated its resilience, ductility, and its response to heat. While PSU is not flame-retardant, it excels in high-temperature and chemically challenging environments. It’s ideal for applications where extreme heat and chemical resistance are key.
