    What is Rapid Prototyping?

    Rapid Prototyping enables you to quickly, sometimes in a matter of days, create a physical product model. This model can serve as a proof of concept, or even for functionality testing, before you invest in more expensive tooling such as injections molds.

    Here are some common rapid prototyping technologies:

    • 3D printing (Plastic and metal)
    • CNC (Metal)
    • Vacuum injection molding (Plastic)

    When do I need a Rapid Prototyping Company or service?

    Tooling used for mass production can be expensive, often costing thousands of dollars. Further, you cannot make changes to, for example, an injection mold once it’s already made.

    Further, it can take up to two months before a mold is ready for production.

    You can’t exactly ‘play around’ with different designs given how expensive and time consuming it is to make injection molds and other tooling.

    That’s also where rapid prototyping comes into place.

    Imagine that you have a product concept that you want to raise funds for on Kickstarter or Indiegogo. Or, perhaps you want to test and tweak the form and function of a new product idea.

    That’s when rapid prototyping makes sense.

    How much should I expect to pay?

    Here are some examples:

    • 3D Printing: US$10 to US$50 per part
    • CNC: Starting from US$70

    Can my existing supplier offer rapid prototyping?

    No, manufacturers rarely have in-house equipment such as 3D printers and CNC machines. While they may be able to refer you a rapid prototyping company, my recommendation is that you find one to work with directly.

    Can these companies also manage mass production?

    No, rapid prototyping companies are specialized in making product models and parts. They don’t have the assembly lines and workers required to take your product to mass production.

    What do I need to prepare before contacting these companies?

    While it depends on the product, you should prepare CAD files or design drawings before you contact any of the companies in the list below. In addition, you should also have a material specification and decide what type (e.g. CNC or 3D printing) of prototype you need.
