ThermaX PSU

ThermaX™ PSU (Polysulfone) stands out as one of the most advanced solutions in technical filament for high-performance 3D printing. Manufactured in the United States with the highest quality standards, this aromatic sulfone polymer becomes the ideal choice for demanding sectors such as automotive, aerospace, defense, electronics, medical, and industrial applications, thanks to its exceptional thermal and chemical resistance. ThermaX PSU is notable for offering superior mechanical properties even compared to reference materials like ULTEM 9085, with more efficient performance in high-temperature environments, greater resistance to hydrolysis, and remarkable dimensional stability.

This technical filament from 3DTech for 3D printing maintains its structural rigidity even in extreme conditions, withstanding high temperatures without compromising the shape or performance of the part. Its impact resistance and its ability to withstand high doses of gamma radiation make it an ideal solution for components that must resist demanding environments or rigorous sterilization processes, including autoclave, plasma, dry or cold heat, EtO gas, and radiation. Furthermore, its resistance to automotive fluids such as gasoline, oils, antifreeze, and transmission fluids positions it as a material suitable for the development of functional prototypes and final parts in highly technical sectors.

The inherently flame-retardant nature of PSU, with low smoke emission and toxicity, complies with the strictest safety regulations, making it perfect for applications where fire resistance is critical. Added to this is a uniform and controlled coefficient of thermal expansion, which ensures high repeatability in the manufacturing of parts, ideal for industrial processes that demand consistency and precision.

ThermaX PSU is much more than a technical filament: it is an advanced solution for those seeking to take additive manufacturing to a professional level, with reliable, precise, and durable results.
