What Is The Prototyping Process And Why Does Speed Matter?

What is prototyping? Prototyping fundamentally refers to the process of taking design ideas through to physical and multi, dimensional verification. As an important step in a product's transformation from concept to mass production, rapid prototyping is an extremely efficient upgraded version of it.

Speeding up the prototype development cycle allows for more design iterations, quicker error detection, and ultimately, a faster time-to-market, which hence is considered its main value.

Conventionally, making prototypes from molds and handwork took an average of 4-6 weeks, whereas, rapid prototyping, which is a digitized process, can reduce the first-piece lead time to 3-5 days.

Market research indicates that for every month a product enters the market earlier it can acquire about 15% of the market share, therefore, rapid prototyping has become a key competitive advantage for companies.

Comparison of Traditional and Rapid Prototyping Delivery Cycles

Prototype Type	Complex Part Delivery Cycle	Complex Part Delivery Cycle	Design Iteration Time Per Cycle	Maximum Annual Iterations
Traditional Prototyping	2-3 weeks	4-6 weeks	1-2 weeks	10-12 iterations
Rapid Prototyping	1-2 days	3-5 days	1-3 days	50-60 iterations

How Does Rapid Prototyping Actually Achieve Faster Delivery Cycles?

Rapid prototyping can overturn the efficiency of traditional prototyping, with the core being digital processes and flexible technology selection, eliminating the need for time-consuming molding and enabling prototyping rapid to be implemented.

Its process compliance meets ASTM E1340-96 standards, and the core is divided into subtractive and additive manufacturing.

1. CNC Precision Machining (subtractive):

As the core process of rapid prototyping, it discontinues the use of molds thus, it can reach the accuracy of ±0.01mm. It serves a wide range of materials, aluminum 6061 and ABS included, satisfying the majority of functional prototype requirements.

2. 3D Printing (additive):

It is through successive layers of material that the model is constructed and therefore this is the secret of rapid prototyping achieving complex structures feature.

Although it is able to manufacture complex structures that traditional processes cannot accomplish, the surface finishing and material density of the product are not of the same level as those produced by CNC.

To more clearly present the key data differences in the core processes of rapid prototyping, the following is a parameter comparison table for different processes, providing accurate reference for process selection:

Process Type	Precision Range	Processing Speed	Applicable Materials	Unit Processing Cost (USD)
CNC Precision Machining	±0.01-0.05mm	Medium Speed ​​(20-50mm/min)	ABS, Aluminum 6061, Titanium Alloy, etc.	80-300
SLA 3D Printing	±0.1-0.2mm	Fast Speed ​​(50-100mm/min)	Photosensitive Resin, Medical Grade Resin	50-180
SLS 3D Printing	±0.15-0.25mm	Medium Speed ​​(30-60mm/min)	Nylon, PA66, Carbon Fiber Composite Materials	70-220
Traditional Injection Molding Prototype	±0.1-0.2mm	Slow Speed ​​(5-15mm/min)	ABS, POM, PC, etc.	150-500
Vacuum Molding	±0.2-0.3mm	Medium speed (15-35mm/min)	Silicone, PU resin, ABS replicas	60-200

JS Precision unites the benefits of different rapid prototyping technologies to pick the optimal prototyping rapid path according to the customer's needs for accuracy, structure, and material, thus balancing delivery efficiency and quality.

Is Rapid Prototyping More Accurate Than Traditional Methods?

It is a typical mistake that the notion "faster speed means lower precision" is false. The precision of rapids prototype varies with the process and sometimes it even surpasses the precision of the traditional one. In fact, the benefits of rapid prototyping are seen in the two-folded assurance of precision and usefulness.

Lateral Comparison of Precision Indicators

Prototypes of traditional injection molding are dependent on the mold and therefore, they usually have a precision of 0.1-0.2mm. Rapid prototype gives superior core process precision:

• CNC machining accuracy is always at IT7-IT9 level, and the tolerance can be as small as ±0.02mm at a diameter of 50mm, which is perfect for functional testing.
• SLA/SLS 3D printing precision is 0.1mm/100mm, thus, it can be used for appearance and assembly verification.

Surface Quality and Material Performance Related Issues

The benefits of rapid prototyping are also reflected in material adaptability. JS Precision's rapid prototype can use production grade materials such as ABS and AL6061 to complete real performance testing, with reference value far exceeding traditional simple models.

Rapid Prototyping Cost Comparison: Is It Really Cheaper Than Traditional Methods?

'Quick is expensive' is a misconception about rapid prototyping. The rapid prototyping cost comparison shows that it has significant cost advantages in the early stages and can save full cycle time and opportunity costs. After 78% of enterprises use it, their R&D costs are reduced by more than 30%.

Short-Term Cost Analysis

Almost the whole cost of traditional prototyping is in the mold, with one mold opening costing $5, 000-$20, 000. Design failure leads not only to a loss of cost but also to a loss of time.

Rapid prototyping does not require molds, and every iteration costs only a few hundred to a few thousand dollars. The cost of three iterations is only 20%-30% of what is typical for a traditional model.

Long-Term Value Analysis

Rapid prototyping has the potential to accelerate the time a product is brought to market, thereby creating the opportunity for extra revenue. Besides, it aids in discovering design problems at an early stage, thus saving the company from having to spend hundreds of thousands of dollars on engineering changes at a later stage.

JS Precision, making use of its Chinese supply chain, is able to further cut the material and processing costs of rapid prototyping by 25%.

Cost Comparison of 3 Iterations between Traditional and Rapid Prototyping (Unit: USD)

Prototype Type	Mold Cost	Processing Cost	Material Cost	Material Cost	Total Cost
Traditional Prototype	15000	3000	1500	2500	22000
Rapid Prototyping	0	4500	4500	800	6500

How Does Rapid Prototype Compare To Injection Molding?

During product development, the key decision is whether the company should carry out rapid prototype or proceed with injection molding, which can even be decided straightaway at R&D. The basic differences between the two would essentially dictate at which level of their adaptation one's going to be. Certainly, prototyping aims at a facilitation of mass production.

Core Difference: Presence or Absence of Molds

• Rapid Prototype: No mold cost, constantly changing design, perfect for design verification and less than 100 pieces, etc. Trial sales demand can be met quickly.
• Injection Molding: Requires mold making work (costing anywhere from a few thousand to a few tens of thousands of US dollars). Although, after mold opening, the unit price is low, mold modification is expensive. Mostly large-scale mass production is appropriate after the design is finalized.

How to methodically determine the best route with respect to quantity?

JS Precision, with a combined experience of years in prototyping and mass production, has no trouble setting forth a decision-making framework:

• 1-50 pieces: Opt for a CNC or 3D printing rapid prototype.
• 50-1000 pieces: Either rapid prototyping or small-batch CNC could be considered.
• Over 1000 pieces: Injection molding becomes the cheaper choice and additionally, this route makes for a smooth transition.

When Should You Choose a Rapid Prototype Over a Production-Ready Prototype?

Different phases of product development call for different types of prototypes. Correctly identifying the right time for a rapid prototype can enhance R&D effectiveness and save from unnecessary cost investments.

Ideal Situations for Rapid Prototyping

• Proof-of-Concept Stage: When it is necessary to demonstrate ideas and obtain approvals quickly, a rapid prototype can convert ideas into a tangible object in no time.
• Functional Testing Stage: When it is essential to carry out real-world testing on the main components, a rapid prototype can be made from mass-production-grade materials, and the results are more trustworthy.
• High Design Uncertainty Stage: When it is crucial to test and iterate quickly, the low iteration cost of a rapid prototype allows for the consideration of several design options.

When is it Required to Switch to a Production, Ready Prototype?

If testing under extreme conditions is required, or in case there are very stringent requirements for the consistency of mass-production materials and processes, a production-ready prototype is a must. JS Precision has the capability of a smooth handover from a rapid prototype to a production-ready prototype.

JS Precision Case Study: How American Medical Equipment Companies Utilize Chinese Rapid Prototyping Services To Seize The Market

Challenge

A US-based medical device manufacturer wanted to create a working handle for a surgical instrument, which would be intricate internal wiring and precision latches, hence, it had to be tested with medical-grade ABS-M30i material.

If they continued with conventional injection molding for prototype development, it would take them 8 weeks and cost more than $8, 000, the slightest design change would be discarded completely. They were in a bind for a dependable rapid prototyping service.

Solution

The company reached out to JS Precision for help and engaged our rapid prototyping service.

1. Optimal Process:

To obtain high precision tolerances of product snap, fit fit 0.05mm JS Precision engineers through DFM (design for manufacturability) analysis recommended high-precision CNC machining.

By using this process along with ABS-M30i biocompatible material, a material density of 99.8% could be obtained, which is significantly higher than the 92% achieved with 3D printing. It paves the way for absolute control of snap-fit gap, which is very hard to realize with 3D printing due to the nature of interlayer bonding.

2. Concurrent Engineering:

Waiting for the arrival of the medical, grade material, JS Precision team finished CNC programming, toolpath simulation, and process parameter debugging in less than 3 days, that too-ahead of schedule.

Simulation errors were controlled within ±0.01mm that not only helped to start production procedure immediately after material arrival but also resulted in maximum production cycle compression and very efficient concurrent engineering.

3. Agile Iteration:

The first component was finished and transported to the US by air within five days. After the customer put the assembly together, their feedback revealed a snap-fit offset of 0.03mm.

Once we got the new drawings, we did the programming modifications within an hour and were able to finish the machining, precision testing (100% pass rate), and shipment of the second optimized part within 24 hours, thus, showing great customer iteration support.

Results

The whole process from placing the order through getting the optimized prototype took only 10 days thereby saving 80% of the time, the total cost of two iterations was $3, 200, which is only 40% of the traditional mold-making cost, the client was able to launch the product 3 months ahead of the schedule, thus, gaining a market share in this category by 15% that year.
