    J850/J835 printers offer the following options: • You can streamline and economize the process of producing models. ❒ Printing models made from different materials on the same build tray (“mixed tray”), in the same print job, eliminates the time-consuming need and expense of loading another material, flushing the system, and sending a separate job to be printed.
  • Page 19 The Stratasys J8 Series 3D printing system can be set up as a single-station system or as a multi-station system. When connected to a local computer network, the system can serve multiple users. In such configurations, each user (client) prepares files for production. A software service, installed on the printer computer, processes jobs and controls the printing.

  • Page 119 Printer waste contains partially cured polymeric material, collected during normal operation and maintenance of the printer. For safety and environmental reasons, this material is kept in a special leak-proof, disposable container. The container has a capacity of 10 kilograms of waste material—usually enough for several months of printer use.
  • Page 120 The waste container consists of a plastic container inside a cardboard box. You typically dispose of the entire waste container—including the box. Therefore, you must assemble a new box and insert a new plastic container before you can install it in the printer. 1.

  • Page 125 After printing models, you should allow them to cool as much as possible before handling them. If additional models do not have to be produced on the printer, it is best to let the printed models cool in the printer, with the cover closed, as long as possible.
  • Page 126 For most models, the most efficient way to remove Support material is by using a high-pressure water jet. One suitable system is the Balco WaterJet cleaning unit. This device is marketed by Stratasys. To clean a model using this device, you place it in the chamber, and you manipulate it and the jet using the built-in, waterproof sleeves.
  • Page 127 Soak models in a 1-percent solution of caustic soda (sodium hydroxide) to remove Support material from difficult-to-reach areas and to give the model a smooth, clean finish. The amount of time you soak the model in the solution depends on how delicate it is and how much Support material needs to be removed, but it is typically between half-an-hour and several hours.
  • Page 128 ❒ For parts with a glossy finish, continue the photobleaching treatment for up to 18 hours more. In Stratasys laboratories, there was a tint reduction of approximately 70% within six hours. After 24 hours, tint was reduced by approximately 90%.
  • Page 129 Models are cured as they are printed, making them safe and stable for a long time. However, proper storage conditions are necessary to prevent deforming. • Keep printed models at room temperature and in a low-humidity environment. • Do not expose models to direct sunlight and other heat sources.
