    What is a prototype?

    After completing the design drawings, the one thing engineers and designers want to do most is what is the actual product of their design? Does the appearance match their design ideas? Is the structural design reasonable? and many more.

    A prototype model can help engineers or designers to check the rationality of the appearance or structure. At this time, the rapid prototype is an ideal solution, because it saves time and costs. Commonly, it only takes 1-7 days to produce, and without making a mold.

    What Are The Functions Of The Prototype?

    Prototypes are usually needed in industrial design and manufacturing. Because the products that have just been developed or designed are generally not perfect or even unusable. Once they are directly produced, they will all be scrapped, which greatly wastes manpower, material resources, and time.

    A Prototype is the first step to verify the feasibility of the product. It is the most direct and effective way to find out the defects, deficiencies, and drawbacks of the designed product, so as to improve the defects until you can’t find the deficiencies in the individual prototype.

    A prototype is generally a small number of samples, the production cycle is short, the waste of manpower and material resources is small, and the shortcomings of the product design are quickly found and improved, which provides a sufficient basis for product finalization and mass production.

    What Is The Advantages of Prototype?

    Usually, 80% of the production cost is determined in the design stage, and prototype making is an important part of the design stage, which means that the prototype has a very important role and incomparable advantages.

    The practice has proved that the production of prototype models not only plays a very important role in product design decisions, but is also a weapon for product information confidentiality and market promotion, which should not be underestimated.

    Below are some key advantages:

    Design Inspection

    The prototype is visible and touchable. It can intuitively reflect the designer’s creativity in the form of physical objects, avoiding the disadvantage of “drawing to look good but can not be manufactured”.

    Check Structure Design

    Because the prototype is assemblable, it can intuitively reflect the reasonableness of the structure and the ease of installation. It is convenient to find and solve problems early.
