So the first step when going from an idea to actually having it developed is to secure some type of design. In most situations it’s simply something sketched out on paper by the inventor. So where do you go from here you might ask. Well, the next step in the patent process is to have professional patent drawings designed from a CAD drafting service. Find one who specializes in invention design. These designers can create your patent drawings with CAD. CAD is a very versatile software program that allows 3d models to be created for manufacturing.
3D Modeling Services
3D Modeling Services are an Inventors best friend. Any inventor should try to find a 3D Modeling Service who deals specifically with Inventions, Prototypes and one that may have Patent Agents to submit all the legal documents for the patent. These invention services should provide the Inventor with a reduced price if they are purchasing more than one service. Once they have designed the CAD file you can have your prototype made.
Generally speaking most prototypes are made with 3d printers. These prototypes can be made at very little cost to the Inventor and can be made quite quickly. 3d printers use a process of layering. They melt one layer of plastic on top of another until the prototype is fully completed. These 3d printers can manufacture prototypes in a wide range of different plastics.
My advice is to go online and Google “Invention Designers” until you find one that can satisfy your design needs for a reasonable price. With all that said, happy inventing!
