How to Create Foam Models Using a CNC Router?

Businesses use CNC high-temperature hot wire cutters for cutting any shape of foam that does not require a flat surface. If there is a requirement to create a 3D design then the CNC Router is required to be employed. A CNC router can be used to create virtually any 3D shape. 

It's a three-axis machine, meaning it is able to move in 3D space by bending and diagonally with movements that resemble carving or milling. The router can produce 3D designs using a variety of materials. You can also visit the site to buy a CNC router online.

The process of machining involves the creation of a 3D model using 3D CAD software, then the model is transferred to the form of a 3D tool-path, which will inform the router about the shape and resolution, the cutting directions, the cutting depth, etc. The designs that can be made with the router are virtually limitless.

If you have a 3D model that you want to design, but it's either too large or thick to machine due to cutter length or height limitations or the foam not being sufficiently thick it could be cut into pieces. Each slice is cut out using a separate router and the pieces will be joined. 

The pieces that are machined will be coated and sanded, then coated with the protective shell and painted. This will also help in getting rid of any visible grooves that are because of the gluing. Routers are also able to make molds that can be later poured using polyurethane or concrete, as well as various casting components.
