Design for Manufacturability

• A Water Jet will cut pretty much anything you can scratch with a piece of sandpaper. Metal is a common material in the Makerspace, but be aware that the machine can also run on wood, plastic, stone, glass, tile, carbon fiber, and more.
• Ensure raw material is larger than the part by at least 1" on each side, which allows for your raw material to be clamped down to the slats on the machine.
• Cut all edges of your design; do not include any raw material edges in the design as alignment is never perfect. For example, a square should be made of four cut sides, not two cut sides and two raw stock edges.
• Stick with closed paths (shapes). Closed paths are required for the machine to properly compensate for the conical kerf of a water jet stream. Open paths increase setup/programming time and confuse the machine's 5-axis kerf compensation, resulting in angled edges on the part.
• Be prepared to remove tabs on small parts. Tabs are necessary to prevent small parts from falling into the tank and getting lost (annoying) or popping up and breaking the nozzle (expensive). Tabs are about 3mm wide and will be added by the machine operator. They can be removed by filing or sanding.
• Save finishing steps (polishing, etc.) until after your parts are cut. Back-spray from the jet's interaction with table slats will abrade the under-side of the material during cutting. In metal, this looks like a slightly rough area similar to a sand-blasted finish.
• The cutting "tool" (water jet stream) has a diameter of 0.035". This effectively puts a radius of 0.018" on all features. Features in this size range (tiny) will likely be degraded or missing.
• Typical fixturings require material to have sufficient strength and rigidity to remain stationary during cutting.  Thin or unstable materials may require sandwiching between additional sheet materials to facilitate cutting, or may be inappropriate for waterjet cutting altogether.
