Metal Prototype Machining and Other Options

Simply put, prototype machining produces a small number of parts before generating a bigger batch. Most businesses opt for prototype machining for appearance and testing purposes.

The former checks how the part will look after production, while the latter is more concerned about the performance of the part and whether it will perform its intended purpose.

To get a reliable turnaround, you need precision capabilities. Getting a dedicated business to handle such precision is no walk in the park because talk is cheap. At Glenn Metalcraft Inc., we provide unmatched prototype designs that give you a high ROI.

What is a prototype? 

A prototype is an early version of a product that is created to test its concept and performance. Ideally, you can’t produce a part in large quantities before testing it, and the best way to do it is through prototyping.

A prototype allows you to evaluate a product and improve its accuracy, quality, and design. Prototypes often fail during testing, and it’s usually a good gesture because designers can detect defects early, correct them, and produce a reliable final product.

When are prototypes used? 

Prototypes come in handy during the design process. Industrial engineers can test products through prototypes before they can begin mass production. Additionally, prototyping can be used to evaluate an existing design or product and improve its precision.

Most of the time, theoretical tests don’t provide real-life solutions. As a business, the only way to stand out and serve your clients beyond expectations is to ensure your product is well-tested in the design stage. 

Through prototyping, errors in the final product are not passed directly to consumers. The process is also cost-effective for businesses.

The prototyping process

The prototype machining process provides quick feedback to the engineers on the performance of the design. Through feedback, the engineers can go back to the drawing table, improve the prototype, and have an effective final product.

However, the prototyping process has some crucial steps to obtaining optimum performance. They include:

Design review

The first step engineers undertake is to review the design using a 3D CAD system in molding. At this stage, engineers can get an insight into the most efficient design features and make adjustments before the model is produced.

Engineers can plan and ensure that every prototype can be produced efficiently on a large scale because some prototypes are difficult for mass production.

Creating a 3d model

After engineers have correctly mapped the design review process, the next step is to create a 3D model. The molded prototype is then sent to a machine shop for production using a CAM program.

Engineering the prototype

The last step is to engineer the prototype. CNC prototyping can be used in this process; however, it’s not cost-effective compared to 3D printing, especially if you need to cut expenses in the prototyping stage.

The design roars to life after the prototype is finally produced. After that, the prototype can be put into mass production.

Benefits of prototyping

Different prototype parts play different roles, all in harmony to have an efficient final product. A lot goes on during the product development stages, and we can’t truly appreciate prototyping without listing its benefits. They include:

  1. You get to receive feedback from end users, such as customers
  2. You get to discover design problems early and correct them.
  3. You get a precise estimate of the production cost
  4. You’re able to test and determine if the product is durable
  5. You can improve the product
  6. You can raise funds and find investors because you have a working prototype to demonstrate.

What are the advantages of metal prototypes? 

Metal Prototype Machining

Metal prototypes are made using metal manufacturing techniques such as CNC machining, sheet metal forming, and casting. Although you can use plastics for prototypes, metal is preferred because it closely mimics the final products.

Some of the advantages of using metal prototypes include the following:

  • You get better functional and mechanical performance
  • You get precise, accurate testing
  • You get better aesthetics
  • You get a higher chance of convincing an investor
  • It’s easier to move to the next phase, which is the production

What methods are available for making metal prototypes?

The available methods for making metal prototypes differ in mechanical results achieved, costs incurred, and the time taken in production. To get a better glimpse, we will take a look at some of the methods.

Metal machining

CNC machining uses instructions from a computer to cut a metal block. The method is relatively affordable because you can make duplicates easily or share the design with other parties. However, the subtractive nature of the prototype machining process leads to material wastage.

3D printing

3D printing, just like CNC machining, uses design input from a computer. The 3D-printed prototypes stand out from the rest because of their complex features, especially in the internal sections. In addition, you also get the design at a low cost, although the surface finish may not be impressive.

Metal casting

During metal casting, you pour hot liquid metal inside a mold. When the mold cools down, it becomes a part. Metal casting parts are solid and high quality, but quality comes at a price. You require specialist equipment, which is quite expensive.

CNC Machining vs 3D Printing

Choosing between CNC machining and 3D printing is a common question for anyone looking to create metal products. Both machines produce a wide range of metal parts and offer unique perks. However, not every business will benefit from using both, and the wrong choice could cost you in terms of quality and money. How do you know which manufacturing process your company should invest in? 

This guide will take a look at everything you need to know when comparing CNC vs 3D printing. It will help you make an informed decision and choose a process that’s better suited for your needs. In the end, if you decide you need a reliable expert for your metal parts production, call Glenn Metalcraft to have your parts shipped directly to you.

CNC Machining Basics

CNC stands for Computer Numerical Control. An engineer designs software to guide the CNC machine to build parts. Because the part is built by software and machines, the entire process is very precise. 

CNC machines are capable of producing parts through a process of subtractive manufacturing. With subtractive manufacturing, machines take a block of material and remove (subtract) pieces to form the final metal component. 

CNC machining has been around since the 1950s, which makes it a traditional manufacturing process. However, the original technology has been improving ever since. For example, companies like Glenn Metalcraft now operate on 6-axis machines, making the process quick, efficient, and highly accurate. 

With machines like the HAAS R2000IB 165R, Glenn Metalcraft can handle large payloads and functions such as: 

  • Material handling
  • Drilling
  • Tooling
  • Press tending
  • Spot welding
  • Assembly

3D Printing Basics

One of the biggest differences in CNC vs 3D printing is simply how it works. As mentioned before, CNC machining is subtractive. However, a 3D printer functions as an additive machining process without support structures. 

With the additive machining of a 3D printer, metals are added layer by layer to build parts. First introduced in the 1980s, it has become more prominent and common in recent years. 

3D printing also uses software to build metal parts, but its capabilities in terms of size and handling are limited compared to those of CNC machines.

CNC Machining vs 3D Printing: How To Choose

Metal automotive parts created with CNC machining, not 3D printing.

As you learn how the two manufacturing processes work, you may already start to realize which is right for you. Here are some key differences between the two options to take into account when considering CNC vs 3D printing.

Speed

When it comes to large orders, nothing beats computer numerical control. These machines reduce the need for operators as they can handle much of the process from beginning to end. They can also handle large pieces on their own and work quickly from one part to the next. 

While a 3D printer can be fast, it can’t produce large bulk orders as quickly and only takes on what fits on the printer bed. So when you need a large order done accurately and speedily, CNC machining may be the better option for you. 

Price

You may not see any difference in price per unit between the two manufacturing processes for some smaller orders. However, for large orders, CNC machining’s speed makes it more cost-effective. Because large quantities are so well handled by the CNC process, you won’t see a significant increase for a large-scale project.

If you’re truly on the fence between 3D printing and CNC, get some quotes from various experts to better understand how your specific order may affect the prices. As a rule of thumb, medium to large-sized orders will get lower prices from CNC machining engineers. 

Size

You can get it all taken care of, from the smallest to the biggest metal parts, by CNC machines. This is because the equipment is made to handle any large block of material and turn it into the final product. These machines are even used to make metal parts for automobiles. 

If you want a large metal part fabricated, it will be far easier to find engineers with the right CNC machines. 

On the other hand, a 3D printed part is limited to the equipment’s size, which is currently significantly smaller than today’s standard CNC machines. While you might find large 3D printing equipment, you will have to shop around. And, it’s not by any means a guarantee that you’ll find what you need. 

Precision

When you send out to have parts created, you want the most professional final product. It won’t do to have jagged surfaces where filaments were laid imperfectly. So when considering whether to choose 3D printing vs CNC manufacturing, know that the 3D printer will work best for less precise components. 

Computer numerical control metal 3D spinning is the way to go for the smoothest surfaces and cleanest lines — it gives you the best results. Any parts needing a tightly toleranced surface, such as key components or tools, require a ready-to-use finish best provided by CNC manufacturing.

Both CNC machining and 3D printing have their own merits. However, one will be better for your project and company’s manufacturing needs than the other.

CNC machining offers a cost-effective, precise, and quick manufacturing process if you’re producing on a large scale. If you’re only looking for a small batch of parts that don’t require the highest quality finish, a 3D printer may give you exactly what you’re looking for at the lowest price.
