Guide To Rapid Prototype & Buying F.A.Q

Although the rapid prototype has existed in many industries for countless years, most people still don’t understand what is it, classification, manufacturing process, etc.

So we have written a FAQ guide for you to understand more deeply.

    1. 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.

    2. 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.

    3. What are the advantages of the 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.

    Functions testing

    The prototype can simulate the final form of the product, including functional form, curved surface form, etc, so can be tested for certain functions.

    For example:

    Using materials with a certain strength (such as ABS, PC, etc.), a functional prototype with an internal structure can be manufactured. This can check whether the structure of the product is reasonable, whether the wall thickness meets the requirements, whether the moving parts are smooth, etc.

    It can also be used for aerodynamic testing. When designing high-speed moving objects such as automobiles, high-speed trains or spacecraft, put a 1:1 prototype into the wind tunnel for intuitive aerodynamic research.

    Reduce risks

    Because making plastic mold is generally very high, the price of relatively large molds is from $5,000 to $3M. If the structure is unreasonable or other problems are found after the mold is developed, there will lose much money.

    The rapid prototype can reduce these risks before making the plastic mold.

    Small volume production and assembly can get market feedback rapidly, trial product is modified until it is finalized. This helps greatly reduce risks to you.

    Quickly occupy the market

    Because prototype production is fast, you can use prototypes for publicity and pre-sales before mass production, this is a proven way to occupy the market as soon as possible.

    Reduce costs

    A product has a design defect, if it is put into production, may cause hundreds of thousands or even millions of dollars in losses.

    The steady progress of the design process is necessary. Therefore, it is very important to find the defects in the product design process, and correct them in time to avoid subsequent production problems.

    How to find design defects? The simplest way is to make a prototype.

    Through the prototypes, the final shape, size, structure, and color can be obtained at a relatively small cost, and important information such as product weight and quality can be predicted (This affects the packaging cost, transportation cost, and raw material cost). And from this estimate the sales price and sales profit of the product.

    If the cost exceeds the initial design, it can be adjusted in time until the target range of the cost is reached.

    Therefore, a prototype is an effective means of enterprise cost control.

    4. How many types of prototypes?

    According to usage scenarios and production processes, prototypes can be divided into several types.

    4.1 Classified by manufacturing technologies

    Hand-made prototypes

    As the name suggests, the main workload is done by hand. It is suitable for some products with simple design, low precision requirements, small size, and lightweight. At present, there are few completely hand-made models because they are not suitable for the requirements of current industrial designs.

    CNC machined prototypes

    The main workload is completed by the CNC machines. CNC machining can produce the parts required for drawings very accurately. With its advantages of high precision, high efficiency, and adaptability to the processing of small batches of multiple types of complex parts, it is a very popular way to become a prototype model.

    3D printed prototypes

    The main workload is completed by a 3D printer. 3D printing is a very popular way to create products in recent years. When requesting small quantity parts which with complex shapes or inner shape, 3D printing will be more efficient and accurate than the CNC machining.

    4.2 Classified by materials

    Plastic prototypes

    The raw material is plastic, such as ABS, PC, PPS, Acrylic, POM, PS, PE, etc. It is widely used in TVs, telephones, electric fans, refrigerators, etc., most of which refer to housings or assembly parts.

    Silicone prototypes

    The raw material is silica gel, which is mainly used as displays the product design shape, such as cars, mobile phones, toys, handicrafts, daily necessities, etc.

    Metal prototypes

    The raw materials are aluminum alloys, stainless steel, magnesium alloys, and other metal materials, mainly the prototypes of some electronic products, such as notebook computers, mobile phone accessories, MP3 players, CD players, etc.

    4.3 Classified by use scenario

    Appearance prototype

    It is mainly used to observe the appearance of the prototype. The appearance prototype requires an exquisite surface, accurate color, but its low requirements for internal processing.

    Structural prototype

    The structural prototype is mainly used to verify the rationality of the product structure, the size of the structural prototype is more accurate. The structural prototype is assemblable, so it can intuitively reflect the rationality of the structure and the ease of installation. It is convenient to find and solve design problems early.

    Function prototype

    If the prototype is required to be realistic in appearance and functional, this type of prototype is called a functional prototype, or it can be said to be a finished product, which can be sold directly, and most of them will be taken to the exhibition and can be well displayed to customers.

    5. How to make a prototype?

    There are many ways to make prototypes, such as 3D printing, CNC machining, vacuum casting, rapid tooling, laser cutting, metal stamping, and so on.

    The characteristics of each manufacturing method are different, and you need to choose one or more ways according to your product requirements, materials, design, and quantity.

    Here, I briefly introduce the 3 commonly used manufacturing methods:

    CNC Machining prototypes

    CNC machining is the most commonly used method of machining prototypes. CNC machining has many advantages, such as high precision, stable quality, high production efficiency. A wide range of plastics and metals can be machined. For some parts with very tight tolerance requirements, CNC machining is an ideal choice.

    3D printing prototypes

    3D printing is currently a very popular manufacturing method. Some companies directly equate rapid prototypes with 3D printing.

    3D printing is additive manufacturing, which is based on digital model files, using powdered metal or plastic and other bondable materials to print out prototypes through layer-by-layer printing.

    3D printing is very fast, some prototypes can be produced within 1-2 days. and it is an ideal way for some models with complex internal structures. However, the range of materials it can choose is not as many as CNC machining.

    Vacuum casting

    Vacuum casting technology is to use the existing products to make a silicone mold, and then use materials such as PU, ABS and other materials for pouring in a vacuum state, thereby cloning a prototype copy of the product.

    This method is mainly used for small volume production. The production cycle is short and the cost is low, but the quality is not as good as CNC machining.
