Screenprinting

This is an experimental design for reusable screenprinting screens. The basic idea is that a scoop coater is used to cover stainless steel screen with acrylic paint, which is used as a resist. A laser engraver is then used to remove the resist where necessary. After printing, the scoop coater is again used to fill the areas where resist was removed.

Bill of Materials:

• Stainless Steel Mesh
• 2020 Aluminum Extrusion
• Silicone Squeegee
• Acrylic Paint (any)
• Screen Printing Ink

Safe Operating Procedure:

Before using:

• Ensure that the screen has been properly coated and dried.
• Check that there is no tearing of the screen near the edges.

While using:

• Print quickly, to prevent ink from drying in the screen.
• Pre-coat the screen with ink, before laying it on the substrate material.

After using:

• Wipe excess ink from inside of screen.
• Wash remaining paint in appropriate sink.
• Hang to dry, and let managers know that the screen is ready to be recoated.
