What is rapid prototyping?

According to Wiki, rapid prototyping refers to a method that quickly fabricates a high-quality physical model by using CAD data. This is a fast process and is mainly completed by using 3D printing or other additive manufacturing technology.

However, as the related manufacturing development, the technologies can be much wilder by today. Other technologies are also be used in rapid prototyping, including CNC machining, injection molding, vacuum casting, casting, sheet metal prototyping, and more.

What are the prototyping materials?

In the world of instant prototyping industry, more materials are being developed constantly, there are a lot of different materials for an engineer to choose from.

Below is a list of useful materials. The prototype companies choose the right one depending on the finished part required by the customer.

• ABS
• Acrylic
• Polycarbonate
• Nylon
• Silicon
• Rubber
• Aluminum
• Stainless steel
• Copper

Why prototyping services are needed?

Prototypes can be done cheaply with a fast turn-around timetable. They can be used as a fitment check, final testing, improvement design change to have the best design product.

Besides, if we run a prototype build, it can make sure the mass production run smoothly.

In a word, the prototype service can ensure a quality finished product. It saves time and money for both the production company and the final end-user.

What are the main rapid prototyping technologies and services?

To create a prototype product, there are flexible manufacturing technologies for you, the main types are as below:

√ Stereolithography (SLA) 3D printing rapid prototyping

SLA is one of the most common types of additive manufacturing for plastic prototypes and low-volume production. It is ideal to be used to create complex components with relatively fast production lead time. However, the limitations are that printing material is limited to photosensitive resin, and surfaces are stair-stepping.

√ Selective Laser Sintering (SLS) 3D printing fast prototyping

SLS uses a laser as the power source to sinter powdered material, move the laser automatically by a 3D model, and bind the material together to create a solid part.

It can be directly produced metal parts and has a wide selection of materials. The limitation, on the other hand, is the rough and grainy surfaces.

√ Fused Deposition Modeling (FDM) 3D printing rapid prototyping

FDM is the most cost-effective first prototyping technology. It is suitable to be used in low-volume production with a higher number. But it has the limitation of ugly cosmetics with visible lines. To overcome this obstacle, a polishing step can be added to remove the lines.

√ CNC machining rapid prototyping

CNC machining is one of the most important prototyping methods. The normal processes include milling, turning, drilling, threading. It can create complex parts with all kinds of materials. Besides, the parts can reach to be a very tight tolerance with a fine surface finish.

√ Rapid injection molding

Rapid injection molding can offer high-quality parts with the low unit cost. It is ideal to use this technology to create a prototype build with a higher quantity.

√ Sheet metal fabrication

Sheet metal prototyping technology can avoid expensive tools. It is proper to produce custom metal parts with a wide selection of materials and finishes for a variety of engineering industries.

√ Vacuum forming

Vacuum forming prototyping is ideal to make rigid or flexible plastic prototypes, the raw material is from hundreds of casting polymers. This technology is good to make a large size of parts.

Besides, the production can be repeatability as the silicon molds can be used more than 10 times, it is one the perfect way for low volume manufacturing.

What is the application of rapid prototyping?

Due to the vast advantages, prototyping is used in almost every manufacturing industry. It can be used in the application of design, engineering, analysis, manufacturing, tooling, and more. When it comes to the specific industry, it can be as below:

• Aerospace industry
• Automotive industry
• medical device industry
• Military Industry
• Jewelry Industry
• Custom machined parts
• Consumer Goods and Electronics
• Healthcare

What is the rapid prototyping process?

In general, there are four steps for a typical additive manufacturing process such as 3D printing.

First, create a CAD model by using design software such as AutoCAD, Pro/Engineer, Solid Works, Or 3D laser scanner.

Secondly, covert the CAD design file to the format that a machine can read, this is usually in an STL file format.

Thirdly, run the machine for production. The machine starts to build layer by layer until the prototype component finished.

Lastly, take the part out from the machining and make the second operation such as deburr, polish, painting.

What are rapid prototyping advantages and benefits?

Usually, a rapid prototype sample can be finished at a fast time at a low cost. It takes a very important role in the whole project development.

First, rapid prototyping takes ideas and concepts from flat visuals to hands-on products. It helps the management team to review and kick off the whole project.

Secondly, with a physical working sample, the design team can test and verify the design. It helps them to improve the design and have a perfect design product in a short time. Besides, when it comes to the manufacturing process, it has fewer production problems.

Lastly, the marketing team can use a prototype sample to get start the market sales work before they have a production product. It helps them to promote sales better.

What are rapid prototyping disadvantages and limitations?

There are quite a several including the following:

The quality is not as good as mass production product for a lot of cases, the material properties like surface finish, strength, elasticity becomes slightly low.

Besides, the low-cost rapid prototyping machines do not have good accuracy, the finished prototype part might also have a low tolerance.

Thirdly, the quantity can’t be too large. In other words, it is not cost-saving if quantity is very high.

How much does the rapid prototype part cost?

This is a tricky question. A prototype price can vary from $10 to more than $1000, it all depends on the specification requirement. However, we can check into all the cost parameters, helping us to figure out where are cost are from. We have the list here, it includes machining method, material, dimension, surface treatment, labor cost, quantity.

√ Machining method

The main machining method is CNC machining, 3D printing, vacuum casting, rapid tooling, each one leads to different cost and price. Most prototypes need one machining method, but some might need more than one method. Usually, CNC machining is relatively more expensive, but 3D printing is a cost-saving way.

√ Material

Under the same process, the metal material is more expensive than plastic material, the imported material cost more than the domestic one.

√ Structure

It takes more machining time for the large and complex component, the cost turns higher accordingly.

√ Surface treatment

This belongs to the second operation process. There are polish, oil spraying, sandblasting, silkscreen, plating, each leads to different costs.

√ Labor cost

Labor costs in developing countries are higher than in developed countries. For instant, the USA labor cost is always more expensive than the cost of a Chinese supplier.

√ Quantity

Same as low-volume manufacturing or mass production, larger quantities can save cost and leads to lower prices.

In a word, if you want to have a low-cost prototype, all you need to do is to pick the cost-saving option from above cost parameters.

If you want to have a solid price figure for your custom part, you can talk to a professional prototyping company like RapidDone, we can give your quotation within 24 hours.

What to consider when selecting a Rapid Prototyping Process?

The process selection is important that it is the success parameters of the prototyping build.

Below related parameters should be considered when it comes to a prototype project.

• Purpose
• Quality
• Budget
• Complexity
• Quantity

Among them, quality is the most important factor which should be considered at the beginning.

why do you need a prototype?

It is a tricky subject, different people have a different answer for this. However, we still can figure out the same common theme.

Prototypes are usually built for engineers as design assess,they spend the money on this to get a risk evaluation.

In other words, Prototyping is a progressive staging of risk evaluations. It can help the design team reduce design defects and a less defect rate during production.

What is the difference between rapid prototyping additive manufacturing and subtractive manufacturing?

Additive manufacturing refers to a process that adds materials layer by layer to create a component. 3D printing is the most popular technology and becomes the synonym with rapid prototyping.

Subtractive manufacturing, on the other hand, is the opposite. It is a progress that cut materials from raw material such as solid blocks, rods, plates, tubes, and more. The most typical method is CNC machining including the processes of cutting, drilling, threading, and grinding,

At RapidDone, we offer both prototyping machining ways for your prototype build, low-volume manufacturing, and mass production.

SLA 3D printing

What are Tips for creating rapid prototyping projects?

√ Optimize the design

Try to use a hollow design and add drain holes for it.

When there are larger parts, it is a cost-saving way to assemble large parts from multiple prints.

Keep wall thicknesses above the minimum specifications.

Avoid the features of angled walls and steep overhangs.

√ Keep close communication with your prototyping suppliers

Manufacturing experience is important to get a successful Rapid prototyping project. If we can include your suppliers early in the design process, we can collect important feedback on alternative paths from them. This can help us to identify the design risk, get a better design, and lead to a more successful production.

√ Choose the right technology

To create a prototype part, it might have several options for machining technologies such as 3D printing or CNC machining.

In conclusion, to make the correct selection, you should understand your need. For example, if you need it for visual demonstration, you can use a normal material with SLA printing. If you use it for testing the mechanical attributes, it might be better to use the CNC machining method with a stronger material.
