There are lots of ways to manufacture the reliefs and to fit them into larger designs. Which methods are most appropriate for you depend on what you're doing and what software you already have for design and machining. See our
software guides to learn more.
Any CAM software or 3D printer software can machine an STL file. If you want to incorporate the reliefs into a broader project, check the software guides. These guides do not represent all software on the market, so if you do not see yours check to see if your design software can import STL files or height map images, or
ask us.
