Maple Veneer with MDF Core (Medium Density Fiberboard Core)

Walnut Veneer with MDF Core

Description

Our maple/mdf has two maple veneer faces and a medium-density fiberboard core. The exterior faces are furniture-grade hardwood, but because the veneers are laminated to an mdf core, the material is very smooth, solid, and dimensionally stable.

MDF (medium-density fiberboard) is made from pre-consumer recycled wood, usually saw dust from a saw mill or wood chips from lumber operations. The wood particles are mixed into a dough with a polymer binder (e.g., “glue” or “resin”) and consolidated under heat and pressure to form a panel.

Laser Cutting

Laser cutting Maple with MDF Core works beautifully, with most lab cutters cutting up to 1/4in and many cutting up to 1/2in or more. The laser does leave a dark charred edge. Most people leave it as is, but if you prefer, you can easily sand the edges to remove the charring.

Specifications and Dimensions

We stock Maple on MDF in 1/8in nominal thicknesses. The actual thickness of the “1/8” is 0.118in. Of course, MakerStock provides pre-cut maple-faced MDF panels in the right sizes for the laser cutter, or to a size convenient for your project. All MakerStock panel dimensions are cut to tolerances of +0in/-0.188in. That is, the panel will always be up to 3/16in undersized so that it will definitely fit a machine with the corresponding nominal bed size.

You can finish maple-faced MDF like any hardwood. We like the wipe-on Minwax polyurethane. Sand first, and then apply thin coats, with light sanding between applications.

The density of Maple-faced MDF is about 788 kg/m3 or 0.028 lb/in3, a bit more than the constituent wood because of the addition of the polymer binder.

Historically the glue used in MDF (and in plywood for that matter) contained formaldehyde, which could result in off-gassing and potential human health risks. Since Spring 2019, all plywood and MDF sold in the US must comply with quite stringent California and US regulatory standards. The level of formaldehyde is very, very low.
