Pulp Compression Molding

Basics

• The use of 3D Printed or CNC Milled Molds to Form Complex Shapes from Cellulosic Pulp (Paper, Cardboard, New Wood, etc) that has been soaked in water, mixed via a blender, and possibly stabalized via a Binding Agent
• Allows for reuse of short fiber cellulosic waste (Things made from recycled paper that may be too short to reuse in paper etc)
• Allows for biodegradable and/or combustable objects if the right binding agents are used
