Today, we’re delving into the world of high-performance polymers, specifically PSU, or Polysulfone. PSU might not be as familiar as some other 3D printing materials, but it’s gaining well-deserved attention for its impressive properties and versatility.
What Is PSU?
PSU stands for Polysulfone, a high-temperature aromatic cell phone polymer. It’s a member of the polysulfone family and shares some similarities with polyphenyl sulfone, but it’s unique in its own right.
The Remarkable Properties of PSU
PSU boasts a range of impressive characteristics that make it a standout choice for 3D printing:
- Excellent thermal and chemical resistance
- Strength and hardness, with a distinct glass-like sound when dropped
- Hydrolytic resistance, meaning it doesn’t absorb water
- Sterilizability, making it ideal for applications requiring high-temperature sterilization methods like autoclaving
- Food safety, ensuring it’s suitable for culinary applications
- Transparency, with the ability to print clear and transparent parts
- Low density, resulting in lighter parts with the same geometry
Where PSU Shines
PSU is an excellent choice for applications involving hot caustic liquids, gases, and extreme temperatures. It’s especially well-suited for:
- Brake lines and components in cars
- Steam-related parts and devices
- MRI shielding in the medical field
Additionally, PSU’s gamma radiation resistance makes it an ideal material for space applications and MRI machines, thanks to its ability to withstand gamma rays.
Flame Resistance and More
PSU is classified with a V0 flame resistance rating, which means it’s self-extinguishing and exhibits minimal smoke. This is particularly important in applications where safety is paramount.
3D Printing with PSU
Printing with PSU is a rewarding experience. It’s easier to work with than some other high-temperature materials, such as PEEK or ULTEM. PSU exhibits excellent flow characteristics, resulting in minimal oozing. You’ll also notice that it doesn’t tear apart like ULTEM during printing.
Here are some printing recommendations:
- Nozzle temperature: 350-380°C
- Bed temperature: 140-160°C
- Heated chamber recommended to prevent warping
Why Choose PSU?
If you need a strong and reliable material for 3D printing without breaking the bank, PSU is an excellent choice. It provides impressive results and is available at a reasonable cost, especially when you consider the savings due to reduced failed prints and improved layered adhesion.
Unlock PSU’s Potential
While PSU may not have the same level of recognition as some other 3D printing materials, its unique combination of properties makes it a compelling choice. If you’re embarking on a 3D printing project that demands high temperature and chemical resistance, transparency, and safety, PSU might be your ideal material.
