What is Rapid Prototyping service?

Rapid prototyping service means making physical samples of a new product design concept. It is the preliminary step to final production and is most useful when verifying that the finished product looks, feels and performs as expected. There are several reasons why new product developers turn to rapid prototyping. They are used for functional testing, approval, design iterations, crowdfunding campaigns, trade show models, and as a bridge to low volume manufacturing.

 

Prototypes often inspire redesigns, improvements, and other modifications that may not be apparent from computer graphics alone, so in this regard they are beneficial for optimizing designs before committing resources to larger volumes. In fact, the ability to correct design errors early in the development phase not only compensates for the cost of the prototypes themselves, so they are a wise investment.

How does rapid prototyping work?

Rapid prototyping is a set of 3D printing techniques that rapidly produce 3D models to scale from computer-aided design (CAD) files through rapid manufacturing or assembly techniques.


In Rapid Prototyping Services, we bring your CAD files and design ideas to life using fused deposition modeling (FDM) and rapid prototyping techniques on other large industrial 3D printers. We specialize in prototypes, low-volume production parts, tools, fixtures, and more, using our state-of-the-art rapid prototyping technology to keep costs low and high quality output.

What are the different types of rapid prototyping service?

1. Silicone Molding

2. rapid tooling for injection molding

3. 3D Printing (SLA, SLS, SLM, MJF, DLP)

4. CNC machining

 

Any physical model can be a prototype. The difference is the degree to which it reflects the expected finished part.

 

Very simple models can be made from paper, plastic, play-doh, foam, balsa, or other common household materials. These are examples of very low-fidelity prototypes, but they do have the advantage of being easy and inexpensive to manufacture.

 

These types of rapid prototyping service may not run well or for long periods of time, so they are primarily used to get a visual idea of the design and compare it to other parts at scale.

How Could I Choose the Best Service for Rapid Prototyping?

For engineers and product designers looking for rapid prototyping online services to speed up product development cycles. Kesu Group offers a variety of rapid manufacturing processes that can be used to create prototypes quickly and cost-effectively. While any single prototype can be produced in an infinite number of different ways, it is ultimately up to the engineer to determine which process and materials are best for their product. Advances in additive manufacturing technology in recent years have made 3D printing the first choice for engineers looking for a rapid prototyping solution: parts can be printed quickly and inexpensively us


When should I choose 3D printing Services?

3D printing is the most common rapid prototyping process. The main advantages of using 3D prototyping services are speed and affordability. At Kesu Group some 3D printed parts can be manufactured and shipped in as little as a day for a few dollars.

The three most commonly used 3D printing processes for rapid prototyping are selective laser sintering (SLS), stereolithography (SLA), and fused deposition modeling (FDM).

Due to its combination of speed, functional mechanical properties, good detail resolution and low cost, SLS is one of the most versatile methods for rapid prototyping.

SLA has the best surface finish and highest detail accuracy and tolerance of any 3D printing process. SLA is also good at prototyping clear parts, especially using the QuickClear finish on certain materials.

FDM offers a wide range of engineering thermoplastics such as ABS, PC and ULTEM. FDM can quickly produce larger, bulkier parts up to 36 inches in size.


When should I choose CNC Machining Services?

CNC Milling and CNC Turning are excellent rapid prototyping options for parts that require final material evaluation of their final material when prototypes are cut from fully densified stock. Kesu Group can process all kinds of metals and plastics. Many CNC machined parts can be manufactured and shipped within a week. With CNC acceleration options available when quoting, Kesu Group's cost-effective, market-based pricing enables engineers to order multiple prototypes at once, enabling rapid product evaluation.

Due to the additional machine setup and run time, CNC machined parts have longer lead times than 3D printing. 3D printing operates through a direct digital manufacturing process requiring minimal setup or post-processing.


When should I choose sheet metal fabrication services?

Rapid sheet metal fabrication can be a good option for fast flip flat parts that need to evaluate prototypes in their final metal material. These parts can be turned around in a week or less and are often cost-effective enough to manufacture two or more prototype designs in parallel. Aluminum 5052 is the most common sheet metal material used for rapid prototyping, but Kesu Group also offers a variety of alloys including steel, copper and stainless steel.

Lead times for fast sheet metal parts are comparable to fast CNC machined parts, but longer than for 3D printed parts. Much like CNC machining, sheet metal fabrication requires additional machine setup and run time.


When should I use  injection molding?

Rapid plastic injection molding is a process that produces a very durable set of identical parts for testing with multiple spare parts. Rapid injection molding can be used for high-fidelity product evaluation as well as bridging tools for temporary production at product launch. Typical lead time for express tooling is 2-3 weeks for initial parts. Rapid prototyping may be the best process for rapid prototyping over additive manufacturing or machining due to stringent material requirements or mechanical demands that are not achievable in these methods.

While rapid injection molding is slower than 3D printing or CNC machining, it is often critical to see more of the part as close to the final geometry as possible. This is where injection molding excels, with high repeatability and near-net final shape.
