Wavy wall surfaces can be created with 3D printing by using a technique called "variable layer height." This involves adjusting the layer height of the 3D printer as it prints, creating a wavy pattern on the surface. Another method is to design the wavy pattern directly into the 3D model using CAD software, and then 3D print the model with the desired wavy surface. Additionally, some 3D printers have the capability to print with different materials or textures, allowing for the creation of wavy wall surfaces with varying textures and finishes. **

To wallpaper a wooden wall, start by preparing the surface by sanding it down and filling in any cracks or holes with wood filler. Then, apply a primer to the wall to create a smooth surface for the wallpaper to adhere to. Measure and cut the wallpaper to fit the wall, allowing for a little extra at the top and bottom for trimming. Apply wallpaper paste to the back of the wallpaper and carefully smooth it onto the wall, using a wallpaper brush to remove any air bubbles. Finally, trim the excess wallpaper at the top and bottom using a sharp utility knife. **

Finally, use screws to secure the cabinet to the wall studs, making sure it is firmly attached. **
