Procter & Gamble is currently developing a printing process which incorporates a Stereolithography (SLA or 3D printed) fabricated roll core for distribution of multiple inks and chemistry to specific locations on a roll surface. This project will focus on improving durability of that SLA surface through the development/identification of more durable SLA resins, and/or identifying alternate methods for encasing the SLA core, yet still enabling a detailed patterned, printing surface.
The current design is a laminated roll segment which has an SLA core, laminated between a stainless steel mandrel and a stainless sleeve. The external stainless steel sleeve is drilled to provide a specific print pattern through which the desired printing media is distributed. This project will look at ways to eliminate the costly external sleeve through development of more durable resins, or identifying alternate ways to encase the SLA core which are more cost effective and more practical to produce.
