INTAMSYS Whitepaper: Increased performance through heated chamber technology

3D printing has established itself as a key technology in modern manufacturing. A key advance is the introduction of heated chamber technology, which enables the printing of high-performance and temperature-resistant materials. These and other findings were presented in detail in the current white paper “Unlocking the Potential of FFF 3D Printing with Heated Chambers” by INTAMSYS. With the FUNMAT PRO series, INTAMSYS has developed a printer solution that meets these requirements and thus supports the production of complex and high-quality components.

The processing of materials such as polyetheretherketone (PEEK) and polyetherimide (PEI) places high demands on the printing environment. These materials require high interlayer temperatures to ensure good adhesion between the layers and prevent deformation or cracking due to thermal stress. Without a heated chamber, the different cooling rates of the printed parts are a major problem as they can lead to inconsistent shrinkage. The heated chamber provides a stable temperature environment that enables the successful printing of a variety of high-performance materials.

The new technology was developed by INTAMSYS Technology with the FUNMAT PRO series. These printers offer precise temperature control and a stable printing environment. With a maximum internal chamber temperature of 300°C and a generous build envelope, these printers are ideal for industrial use. They enable the printing of large and complex parts with high precision and minimal deformation.

The advantages of the closed circuit systems in the new shot blasting technology are emphasized by experts. These systems enable precise measurement and adjustment of key process variables (KPVs) such as abrasive flow, air pressure and air volume, as well as the distance and angle of the blast nozzle to the workpiece. All these parameters are monitored and adjusted in real time to ensure consistent print quality.

Tests by independent institutions confirm the temperature stability of the FUNMAT PRO series. At an internal chamber temperature of 100°C, the tensile strength of materials such as ABS, PC and PC-ABS increased significantly. This is due to the improved mobility of the polymer chains and the better adhesion between the layers. The uniform temperature distribution within the chamber helps to ensure that the mechanical properties of the printed parts remain consistent.

Overall, it is clear that heated chamber technology offers decisive advantages in 3D printing. It improves the stability and performance of printed parts, reduces production costs and expands the fields of application for additive manufacturing. The ongoing development and optimization of this technology will have a significant impact on the future of the manufacturing industry and enable new, efficient and environmentally friendly production methods.
