Prototype Info Sharing Blog

The processes involved in rapid 3D printing have become more adequate in recent years. While a lot of these processes are competent, we will be focusing on only one of them for this article. The different rapid prototyping techniques will allow you to make your prototype fast. However, they all have preferential uses or applications. We will be singling out CNC prototyping as an essential rapid prototyping technique.

Getting to know these preferential applications and uses could save one a ton of money. More than that, time and quite a few resources could be saved. Once one is properly acquainted with the intricacies of these rapid printing techniques, they realize a vital truth. Using certain rapid printing techniques for certain jobs is nothing short of overkill.

3D Prototyping Technique Available

However, we will outline the few available 3D prototyping techniques before proceeding. This will help our readers to know what to look for when making further research. The techniques include but might not be limited to:

1. CNC Prototyping
2. Rapid Tooling
3. Metal Casting
4. Additive Manufacturing Technique
5. Sheet Metal Printing

For this article, we will consider just one of them. We will now turn our attention to CNC prototyping technology and its benefits.

CNC Prototyping

CNN (computer numerical control) prototypes are made via a carefully controlled computer system. This system integrates human efforts and ingenuity with computer precision to function. The entire process is aimed at getting g or printing models of outstanding qualities and integrity. The use of CNC machines has gone a long way in modern-day manufacturing.

So far, the limits of the technology have not yet been discovered. That is of course within the realm of material or designs with definite shapes. After all, the term 3D in its name means that the printed models have to be in 3D. In simpler terms, the models would be viewable from all sides as well as top and bottom.

Are CNC prototyping and 3D printing the same?

However, CNC prototyping is quite different from 3D printing. Granted their final results are all 3D-created models. However, the two techniques employ different approaches to reach their aim. While 3D printers majorly use a kind of additive method, CNC machines do not. 3D printing usually involves stacking the “ink” materials to form a larger 3D shape or prototype.

The CNC prototypes are made by a more subtracting method. The material used is usually whole. A block shape of whatever material the person would like to use is first prepared. Then the CNC machines work by sort of carving the block into the desired 3D prototype.

An advantage of the CNC prototypes over other 3D rapidly printed models is that they are more compact. Because they are cut from a whole material, they have a higher structural integrity. They are more ideal for large-scale or factory 3D printing. They could work on various sorts of metals as well as plastics.

Conclusion

The CNC prototyping technique is the best choice when large-scale printing is required. Other techniques might still be effective. But this is more precise and prints more durable models.

The design of a product determines 75% of the cost of manufacturing it. Many engineers in prototyping companies focus on the aesthetics coupled with the visual appeal of product design without considering the realities of constructing products. It is costly to design the design concept, especially if it is not viable from a business’s angle. Rapid prototyping is the earlier version from which various forms of a product are developed.

How a Prototype Can Make or Break a Product

A prototype provides you with insight into the functionality of the product design while helping you make changes required regarding your products’ specifications.

Several innovators are forming and destroying their prototypes while brainstorming and tweaking them with the hope of developing a revolutionary product in the long run.

An initial product for a pilot test can have drafts of drawings on a paper, also known as a low-fidelity prototype.

High-fidelity prototypes entail the investment of a lot of time and money. Therefore, prototyping is an excellent way of identifying if the solution presented is ideal for the purpose. It could be for a website or hardware.

It could also be for software. Suppose you are a business professional or entrepreneur. In that case, you should begin from the outset by identifying an effective way of identifying the aspects you are working with before developing a product.

What to Do Before Product Development

a. Create Sketches

You may be tempted to use software to sketch things out or start by coding things, mainly if there is time.

Even so, it is highly recommended that you begin by using a pencil and paper prior to investing in a complicated prototyping tool. This will help you in identifying the key aspects that need special attention while doing the prototype on your machines.

When designing a new product from scratch, one of the first steps is often the most challenging, even though it sounds easy for some people. Solidifying the ideas by drawing can be a daunting task.

b. Have Specifications

After forming sketches, the next step is having specifications for your product. The 3D printing material and other practical tools like laser cutting coupled with CNC milling have changed prototyping businesses by easing entrepreneurs’ lives.

As an entrepreneur, however, you should design product specifications and then define its existing functionalities before using the tools to offer support.

c. Understand Your Target Audience

Before you create a prototype for your products, you should engage prospective customers to know their interests, coupled with their needs. Introduce the concept to them to help them establish if you are providing a solution to them.

Simultaneously, this should help them determine if what you are creating is a problem for them. At this juncture, the innovator can learn the importance of modifying a product where necessary.

Final Thoughts

An expert in creating prototypes can help your startup bring a new product into the market. By working with professionals, you can easily create a pleasing design solution coupled with a strong focus on reducing the entire manufacturing costs.

Whether you want to create high or low fidelity prototypes, you need to follow a procedure that gives you a complete picture of how the product will look and perform. Companies that offer rapid prototyping service for physical parts often want a fast process, and that is why they use a variety of techniques. However, there comes a time when such companies need to outsource such services. For example, if you do not have enough time to work on all the prototypes, the only viable option is to find an expert who understands how to do it better.

The Pros of Outsourcing Rapid Prototyping Projects

One of the most significant advantages of outsourcing rapid prototyping projects is the fast turnaround time. Sometimes, clients want their products to be fabricated fast, and that means that you will need an extra pair of hands to meet their demands. With outsourcing, you can divide the project into smaller parts and have them distributed to different experts. In addition to that, outsourcing ensures that you serve several clients simultaneously, regardless of the size of the projects.

More Creative Control

You will also enjoy outsourcing rapid prototype projects because it gives you more creative control. You will have more control of the way the projects are conducted because you have a team that is backing you up. For example, you can ask for their recommendations on various techniques and see how much creativity they add to your projects. If you are short of ideas, all you need to do is to ask the team to come up with ways of creating the prototypes, and you will end up with the perfect plan.

If you are looking for ways to expand your business, outsourcing rapid prototyping projects may be the best way to go. If your clients learn that you have enough resources to handle every stage of their projects, they will be willing to give you more business. Once they know that they can count on you to deliver the projects on time, they will not hesitate to contact you reach time they have a new project, and that is how your company grows. You will also notice that such clients will recommend you to their contacts so that you have enough work to keep you busy throughout the year.

The Cons of Outsourcing Rapid Prototyping Projects

Most outsourced rapid prototyping projects lead to low printing volumes because of lack of a breakthrough, especially with new clients. However, you can overcome this challenge through aggressive marketing, such as the use of word of mouth. In addition to that, outsourcing can lead to the inadequacy of resources. For example, you may have to spend time and money training your recruits before you can trust them with the projects.

In a nutshell, outsourcing rapid prototyping projects can help you to grow your business and provide fast services. However, you need to plan effectively and find the right experts to work with to avoid problems with your clients. Work with a team of experienced experts to get high-quality prototypes.

An automotive prototype is used to show if a product can be made, the most suitable material for it, and its production equipment. It is a vital part of the process since it helps developers make new automotive products of good quality that attract stakeholders to invest and form a good customer base in the market. The automotive prototype plays a vital role in the designing and processing of cars. In this write-up, we look at the types of automotive prototypes.

Types of Automotive Prototypes

The safety of a car, its performance, and its development are dependent on the prototype. They include:

1. Design Validation Prototypes

Initially, designs are created virtually using computer-aided designs (CAD). A prototype is made to create a physical object using cost-effective techniques like plastic injection molding. It helps manufacturers achieve clarity, visualize the concept, and share it with investors.

2. Pre-Development Prototypes

They are more refined and smooth. They are made once a design is validated, and a stakeholder has shown interest in the product. At this stage (mule stage), the prototype is used to decide whether the item can be used and correct the design errors. Donor cars are usually provided, and their body is taken off. The product is then placed on the automobiles to check if it fits and reacts with the other parts.

3. Manufacturing Process Prototypes

Techniques such as CNC machining, metal stamping, and forming are used to determine the best method of developing the parts. The automotive prototypes easily spot any problems that may arise during production. There are many manufacturing processes, and the most cost-effective one is chosen.

4. Customer Testing Prototypes

They are used for customer testing during the production process. Dialog between the developer and consumer is crucial. Feedback from customers who plan to use cars is essential as it helps engineers pitch their ideas. They can also correct issues pointed out by the potential users and select the best material to be used for the final product.

5. Safety Testing Prototypes

The test carried out is known as Failure Mode Effect Analysis (FMEA). The prototypes are taken through different situations to see how they behave in those respective situations. They are also placed in harsh conditions to show if they can withstand heat, water, etc. without causing any problems that may stop consumers from using the product.

6. Manufacturing Validation Build Prototypes

These prototypes are made last, as this is the final stage of preparation. They are very expensive and take a lot of time to develop them. They help in estimating how long the manufacturing process will take. The method of producing an object for market use is different from that of creating a functional prototype. It is a complicated process that needs high precision. The actual equipment and machines make the prototypes, and the final touches are done.

Bottom Line

Automotive prototyping is a vital process of the development of cars. Multiple automotive prototypes are always developed when a new product is being created. They are often refined to get the best design and methods of processing.

The old-age battle when it comes to injection molds will definitely be steel or aluminum injection mold. The debate is fierce and many manufacturing companies take one side over the other. However, what do you think? Are aluminum injection molds making better than steel molds? If you are confused, we might help you make a decision.

We will compare both molds by using several factors. We hope to find a clear winner at the end of the day. Even if we don’t, we hope things will be much clearer to you by then.

Aluminum Injection Mold or Steel Mold?

How much does each mold cost?

To produce either mold, you will have to spend some cash. However, which one requires less spending? When you consider the initial spending needed to be carried, there’s no doubt that the aluminum injection molds clearly have an edge here.

While this is true, it’s also important to look at the bigger picture. The final cost of each mold might change drastically when other factors are considered. For example, the estimated lifespan of each mold might require you to spend more on the aluminum injection mold.

However, on average, the aluminum injection mold is less likely to cost more than steel.

Which mold is suitable for low volumes?

Again here, the aluminum injection mold just comes out on top. Low-volume runs are always better suited to aluminum injection molds and this is not going to change anytime soon. The reasons for this range from lower costs to the production of more pieces.

I’d recommend that you make sure that you choose a material that matches the volume you intend to use. Some might just be better with the steel mold.

Which mold is suitable for high volumes?

The steel mold comes out on top here. Unlike low volumes, the steel mold is better suited for high volumes and more runs.

The advantage of using a steel mold here is that you get a final product that is sturdy and can last for a long time. All you have to do is to ensure that you carry out proper maintenance.

Which mold cools and heats up faster?

It’s obvious who wins this round. The aluminum just has the perfect material for heating and cooling off quicker. The steel mold is always going to struggle when it comes to this category. The faster your material can cool off, the faster the cycle time is going to be.

When you use aluminum injection molds, you should be able to have a much faster output than with steel molds.

Final Verdict

So what do we think? We think the aluminum injection molds are overall the best type of mold. However, there are circumstances where the steel mold might be better.

However, when considering the facts and the big picture, it’s almost impossible to see how the steel molds come out on top.

So if you are considering what type of mold to use, we would recommend that you use aluminum injection molds for your business. It’s just the better option if we are being completely honest.
