Yes we digitize for 3D embroidery / patches/ applique, 3d also known as puff embroidery or 3D puff embroidery, is a special method of embroidery that makes the design "puff-up", or "raised", thus it is more three dimensional.
3D puff embroidery is another way of sewing, which involves use of foam under the threads. Sewing is normally done on the edge of the form, leaving the middle part of the form having the effect of being elevated – a vivid 3D look. 3D-effect embroidery, by contrast, is direct embroidery with fabric and thread only – no foam. Thick underlay and lots of thread are usually used to achieve the three-dimensional effect.
