Loading Model and Support Cartridges

Stratasys J750/J735/720 printers use up to 12 cartridges of Model material and up to four cartridges of Support material, each weighing 3.6 kilograms when full.

A graphical representation of the cartridges loaded and their current weight appears in the printer interface.

The material cabinet contains a module that identifies loaded printing materials. Tampering with this module will render the printer inoperable and may void Stratasys warranties and service contracts.

Important: If you need to replace the printing material currently installed with another type, see Changing the Printing Material. Otherwise, make sure to replace the material cartridge with one containing the same type of material.

To load Model and Support material:
1.   Open the material cabinet.
2.   Load Model and Support cartridges into their respective compartments.

You should feel some resistance, as a needle pierces the cartridge seal.

3.   Check the printer interface to make sure that the new cartridge is detected and that its weight is displayed.

4.   Close the material cabinet.
Tips about loading and replacing material cartridges:
  • You can replace material cartridges either before or during printing.
  • You can load partially used cartridges, provided that they contain more than 100 grams of material.
Note: PolyJet Studio does not display the weight of material in a cartridge if it is under 100 grams.
  • You can replace a partially used cartridge to avoid the need for replacing it during printing.
  • The cartridge type is automatically detected by the printer. If you replace a cartridge containing different Model material, a message appears recommending that you run the Material Replacement wizard to flush out the old material.
