How to print flexible parts with multiple materials on Connex 3D printers?


  1. Step 1:

    Select appropriate core materials. Use TangoBlack as the core material to increase memory speed. Use TangoGray as the core material to increase rigidity and tear resistance.

  2. Step 2:

    Select appropriate coating materials. TangoPlus™ and TangoBlackPlus have high elongation-at-break values. Use either of them as the coating material to enhance tear resistance. This will also bring the elongation-at-break value close to that of parts printed with TangoPlus materials alone.

  3. Step 3:

    Select a coating thickness. For best results, a coating material thickness of 0.3 mm is recommended. The coating thickness does not affect the external dimensions of the object, which remain unchanged. The coating layer replaces part of the main model material.

  4. Step 4:

    Because the coating material thickness remains constant, thin parts may
    have lower Shore A values than expected. If a part’s thickness is below ~0.8 mm, the core material will not be printed at all. The entire part will be printed using the coating material.

  5. Step 5:

    Applying core and coating materials. See the section on “Coating Objects” in the appropriate User Guide for your Connex 3D Printer.
