Changing the Printing Material

Before producing models using a different type of printing material than is currently installed, run the Material Replacement wizard to flush the print block and feed tubes.

You should carefully plan printing models with different materials to avoid unnecessary waste of the materials currently loaded. The amount of material flushed depends on the flushing cycle chosen and if you are replacing one or both Model cartridges.
Note: When performing manual material replacement, certain replacement options are blocked to protect the system. In these cases, follow the recommendations of the Material Replacement wizard for best replacement options.
To replace the printing material with the wizard:
1.   Start the Material Replacement wizard from the Options menu.
2.   In the opening screen, click Next.
3.   If the printer cover is not closed, a screen appears, prompting you to close the cover. Confirm that it is closed and click Next.
4.   In the Compartment Selection screen, select the compartment(s) containing the printing material you want to replace, and click Next.

5.   From the drop-down menu, choose the material you want to install, and click Next.

When SUP707 Support material is loaded, certain Model materials are not available.
6.   In the Flushing Options screen, choose the appropriate cycle for the Model material you want to install.

Flushing Options

•   Economy. During this cycle, which takes about 20 minutes, the pump purges the Model material from the print block, then flushes the system with the new material.

Since traces of the previous material may be present in the first models printed with the new material, this cycle is usually acceptable when replacing a light-colored Model material with a darker material (such as TangoBlack™ or VeroBlack™), or if the exact color of the printed models is unimportant. In most cases, models will have the mechanical properties of the new material (except when switching between rigid and flexible materials).

•   High-performance. During this cycle, which takes about 55 minutes, the wizard cleans the feed tubes and print block more thoroughly, compared to the Economy cycle, by flushing the system with more material.

This cycle ensures that models will have both color and mechanical properties of the new material. This is important when replacing a dark-colored material (such as VeroBlack or TangoBlack) with a lighter-colored material, and when switching between rigid and flexible materials. This cycle is also recommended when changing the type of Support material.

7.   Click Next, and take note of the warning.

Once you start this procedure, you must complete it before you can produce models with the printer. To perform the procedure at another time, click Cancel. If you continue (by clicking Next) and you do not complete the procedure, you must start the Material Replacement wizard again before producing models.
8.   When prompted by the wizard screen, remove the material cartridge(s) and load the replacement cartridge for the required compartment(s). Confirm this in the wizard screen and click Next.

If the printer does not identify the replacement cartridge(s), the following wizard screen appears.

After identifying the cartridge(s), the printer begins filling the print heads with the new Model material.

9.   In the final wizard screen, click Done.

The printer-control application is automatically updated, and it restarts.

When it opens, the interface displays the new material(s). Objet Studio (on the server computer) is also updated and displays the new material(s).

10.   Inspect the area around the purge unit and clean it, if necessary.
