In the unlikely event of a leak or spill, follow the instructions that are included with the printing material cartridge used.

  • Page 18: First Aid For Working With Printing Materials

    Safety First Aid for Working with Printing Materials In general, try to avoid direct contact with uncured printing material. If skin or eyes come into contact with it, wash the area immediately and thoroughly with water, and follow these first aid instructions. The Material Safety Data Sheet (MSDS) that accompanies printing materials contains important safety information.

  • Page 19: Waste Disposal

    However, special care is required when handling printer waste (uncured printing material). Printing Materials When removing the waste container from the Stratasys printer, wear neoprene or nitrile gloves. To prevent liquid waste from splashing into the eyes, wear safety goggles.

    Figure 3-1: The Stratasys P750K 3D Printer Work Configurations The Stratasys 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 workstation (client) prepares files with Objet Studio software for production.

  • Page 23: Source Files

    The result is that high quality object descriptions mean very heavy files. Most CAD software can export STL files. The Stratasys system utilizes these files for building models (rapid prototyping), and also for directly making molds for mass producing items.
