Is programming a website for a company that prints, colors, delivers, repairs, and develops 3D models unlawful (haram)?

It is permissible to establish a company for 3D printing for lawful purposes, such as models and prototypes for machinery, structures, jewelry, and artificial teeth. However, it is not permissible if it is for animate beings or musical instruments. The design and development of printers are permissible for their use in lawful applications.
