12.2022 First Processing with Adaptive IR Zone Heating System (FFF/FDM Printing)

The equally smooth surface coupled with high strength in the build-up direction was achieved with Apium’s patented IR zone heating system. In this process, only the uppermost layers are melted so that there is a high level of layer bonding. In the meantime, the lower layers can cool down without any further thermal influence on the surface quality.

    Crosslink tester with switching bridge

    Radiation-crosslinkable DIPRO®mid precision polyamides show the following differences compared to conventional PA grades:

    • little warping due to low shrinkage
    • very good surface
    • low influence of air humidity on properties
    • thermostable crosslinking additive, homogeneously compounded, up to 40 %
    • energy efficient due to 35 °C – 40 °C lower melt temperature than PA66
    • maximum 60 % glass fiber reinforcement possible

    Reinforced high-performance PA grades for FFF (filament printers) and FGM (pellet printers)
    All FFF-FGM polyamides with glass fiber reinforcement show extremely low mold shrinkage. This is particularly important for large-format printers.

    PA-Copo + X, 62 % glass fiber, partially aromatic, a possible answer to constantly recurring PA66 shortages.
    The high modulus aesthetic material exhibits unprecedented low mold shrinkage values (0 % md/0.1 % pmd) and is suitable for dimensionally stable metal replacement applications. The tensile strength of 265 MPa is high, and the processing window is relatively wide.
    Mechanical values perpendicular to the fiber are 28-30 % better compared to competitor materials.
    High performance polyamides of the same family with 40 % and 50 % glass fiber reinforcement are available.
