Professional High-Temperature Support Material for Advanced Engineering Polymers

3DXTech ThermaX™ HTS1 High-Temp Support Filament is a specialized break-away support material engineered for use with high-performance thermoplastics that require extreme printing temperatures. Designed specifically for dual-extrusion 3D printers, HTS1 provides reliable support structures for advanced engineering materials that exceed the capabilities of conventional support filaments.

Unlike standard support materials that soften or fail at elevated temperatures, ThermaX HTS1 is formulated to remain dimensionally stable during the printing of ultra-high-performance polymers such as PEEK, PEKK, PEI (ULTEM™), PPSU, PSU, and PPS. This allows users to produce complex geometries, internal channels, overhangs, and intricate engineering components with greater confidence and reliability.

For aerospace, automotive, industrial manufacturing, research laboratories, and advanced additive manufacturing environments, HTS1 provides a dependable support solution for challenging high-temperature applications.

Printability and Support Performance

ThermaX HTS1 is designed specifically for support generation rather than structural end-use parts. The material withstands the demanding thermal conditions required for ultra-high-temperature polymers while maintaining sufficient rigidity to support overhangs and complex features during printing.

Because HTS1 is a break-away support material, it does not dissolve after printing. Support removal is typically easiest while the printed component remains warm. If the model cools completely, gently reheating the part can simplify support removal and improve overall workflow efficiency.

The material is particularly valuable when producing parts with intricate internal geometries that would otherwise be difficult or impossible to manufacture using high-temperature engineering materials alone.

Typical Applications and Use Cases

ThermaX HTS1 is ideal for:

• PEEK support structures
• PEKK support generation
• PEI (ULTEM™) printing workflows
• PPSU component production
• PSU engineering applications
• PPS high-temperature manufacturing
• Aerospace prototypes
• Industrial tooling
• Medical research applications
• Functional engineering prototypes
• Complex internal channels
• Advanced manufacturing components
• High-performance polymer development

Its ability to withstand extreme processing temperatures makes it an essential material for users working with industrial-grade thermoplastics.

Material & Compatibility Information

ThermaX HTS1 is designed for advanced dual-extrusion FDM and FFF systems capable of processing high-temperature engineering materials.

Compatible model materials include:

• PEEK
• PEKK
• PEI (ULTEM™)
• PPSU
• PSU
• PPS

Recommended printing conditions include high nozzle temperatures, heated build surfaces, and heated build chambers commonly found in industrial additive manufacturing systems. The material is not intended for standard desktop PLA or PETG printing environments.

Users should ensure their printer is equipped with appropriate high-temperature hardware before processing ThermaX HTS1.

Why Users Choose ThermaX™ HTS1

Advanced manufacturing professionals choose ThermaX HTS1 because few support materials can withstand the thermal requirements of PEEK, PEKK, PEI, and similar engineering polymers. Standard support materials often degrade, deform, or fail during high-temperature printing, leading to poor print quality and unsuccessful builds.

ThermaX HTS1 helps eliminate these limitations by providing a support structure engineered specifically for extreme-temperature environments. This enables the production of complex geometries while maintaining the mechanical and thermal properties of the primary engineering material.

For organizations investing in industrial-grade additive manufacturing, HTS1 provides an essential tool for expanding design freedom and improving production success rates.
