In today’s exploration of high-performance 3D printing materials, we’re delving into the world of Thermax PPSU by 3DX Tech. This material, also known as polyphenylsulfone (PPSU), goes by various industry names such as Radel or PPSF. PPSU is an aromatic sulfone polymer prized for its ability to excel in high-temperature applications. It boasts impressive thermal properties, exceptional impact strength, low smoke emission, and overall robustness. So, let’s dive into the details.
The Science Behind PPSU
PPSU is a standout in the world of 3D printing materials due to its remarkable heat resistance. It has a glass transition temperature of 231 degrees Celsius, making it one of the most heat-resistant unfilled FDM (Fused Deposition Modeling) materials available.
When you order Thermax PPSU from Vision Miner, it arrives in a metalized vacuum-sealed bag. Even if it’s unsealed upon arrival, don’t fret; you’ll still need to dry it before printing. But more on that later.
Why Choose Vision Miner?
First, you might be wondering why you should buy from Vision Miner. Here’s a straightforward reason: they offer a 3% cashback on every dollar you spend, and you can use that cashback on items like nozzles, spools, glue, machines, accessories, or more filament – giving you a lot of flexibility in your 3D printing ventures.
Applications of PPSU
PPSU’s unique properties open the door to a wide range of applications across various industries. It’s often used in the medical field due to its autoclavable and sterilizable nature. You can find it in medical trays, surgical instruments, tool handles, and anesthesiology equipment, among other things.
PPSU also shines in cryogenic applications, thanks to its excellent low-temperature performance. And its robust chemical resistance allows it to be used in demanding environments where many metals would corrode.
Printing PPSU
When printing with PPSU, your nozzle must be able to reach at least 390 degrees Celsius, with 410 degrees or more being preferable. The build plate temperature should be a minimum of 130 degrees Celsius but can go higher if your printer allows it.
For bed adhesion, Vision Miner’s Nanopolymer adhesive works perfectly. And keep in mind that a heated chamber is essential for PPSU to prevent warping. It’s recommended to maintain chamber temperatures at 90 degrees Celsius or higher.
Before printing, be sure to thoroughly dry your filament. Vision Miner offers an entire kit for this purpose, including vacuum chambers and ovens. Their metal spools are ideal for drying at higher temperatures without worrying about spool warping.
Material Specifications
Now, let’s delve into the technical specifications of PPSU. It has a heat deflection temperature of 190 degrees Celsius for continuous use, while its glass transition temperature is around 230 degrees Celsius. PPSU is an amorphous thermoplastic, meaning it lacks a semi-crystalline structure. You can anneal PPSU for enhanced part strength.
In terms of tensile strength, PPSU offers approximately 55 MPa according to the ISO 527 standard. The tensile modulus is around 2310 megapascals. However, keep in mind that your part’s design and orientation during printing will influence these values.

Environmental and Safety Considerations
While PPSU exhibits good UV resistance, long-term exposure to direct sunlight can make it brittle. It can handle a wide array of sterilization methods, from autoclaving to gamma radiation. In terms of chemical resistance, PPSU performs well against common automotive fluids and is considered safe for food contact.
As for electrical properties, PPSU is a robust insulator with a dielectric constant of 3.21 and a low dissipation factor. In terms of certifications, it boasts compatibility with various standards, making it a reliable choice for critical applications.
Exploring PPSU Parts
To give you a feel for the material’s quality, Vision Miner offers a range of parts. PPSU parts generally come out somewhat translucent, with a slight yellow hue. They exhibit considerable strength and impressive surface finish, making them perfect for demanding applications.
Now, let’s explore PPSU’s mechanical properties. It has a high impact strength, which is immediately evident when you try to bend or flex a part. Overhangs and bridges are achievable, although they might not be as pronounced as some other materials.
PPSU Torture Test
Before we wrap up, let’s see how PPSU behaves under extreme conditions. Vision Miner goes all out to test PPSU’s limits. They set it on fire, subject it to intense heat, and even push it to the breaking point. And PPSU stands its ground.
If you want to give PPSU a try in your environment or with your specific chemicals, Vision Miner offers sample bars that you can test. It’s a great way to ensure that PPSU is the right fit for your application.
