Medium Density Fibreboard (MDF) is a reconstituted wood panel product. It is a dry-processed fibreboard manufactured from wood fibres, as opposed to veneers or particles, and is denser than plywood and particleboard. MDF has an even density throughout and is smooth on both sides.MDF is reconstituted into wood sheets in a variety of widths and lengths.MDF's come in both pre-laminated form as well as plain boards.

Advantages:

• MDF is generally cheaper than plywood.
• The surface of MDF is very smooth, so it's a great surface for painting
• MDF is a great substrate for veneer.
• MDF is very consistent throughout, so cut edges appear smooth and won't have voids or splinters.
• Because of the smooth edges, you can use a router to create decorative edges.
• MDF allows for easy cutting of detailed designs (such as scrolled or scalloped designs) using a scroll saw, band saw, or jigsaw.
