3D Printing Car Parts: A Complete Guide for 3D Printing in the Automotive Industry

The automotive industry has come a long way from the days of manual car assemblies. One of the foremost industries in the world, the automotive sector was also one of the first to start using 3D printed car parts.

However, the industry didn’t start using 3D printing to make parts overnight. It initially started with the use of additive technology to make car prototypes and concept-of-designs. However, manufacturers realized the potential of the manufacturing technique to yield much more. This led to heavier investment into understanding the process.

With 3D printing automotive parts now common, this article will analyze how the process is intertwined with manufacturing car parts.

What Car Parts Can You Print?

You can use 3D printing for the production of most car spare parts. It just depends on the type of 3D printer you have access to. For example, Koenigsegg, a hypercar manufacturer, uses 3D-printed car parts such as their titanium exhaust tips. That is definitely not something you can do on a small-scale printer. However, if your bank statement is strong enough to buy some heavy-duty printers, you can exhaust your imagination by 3D printing various automotive parts.

As long as the part does not get exposed to high temperature or pressure, you can print various car parts. You could even print various innovative additions for your car, such as a smartphone holder.

Now, let’s go back to the big guns. Many huge automotive manufacturers utilize 3D-printed car parts in their production. Examples include Bentley, which uses 3D printing for parts such as their side air vents, exhausts, and side vents. BMW also uses 3D printing for making components for the roof retraction mechanism on their i8 roadster.

Some use the additive manufacturing technique to produce car assembly equipment, e.g., Volkswagen. Its wide application potential is one property that makes 3D printing quite suitable for the automotive industry. The next section will show why 3D printing in the automotive industry has become so widespread.

How 3D Printing is Impacting the Automotive Industry?

While there are no fully 3D-printed cars yet, the influence of 3D printing in the car manufacturing industry cannot be underemphasized. It has made the production process less expensive and faster. Apart from its cost and time implications, we’ve explained some of its other impacts below:

3d print metal partSpare Part Production

Cars consist of numerous parts, some not even in production by the manufacturing company. It is understandable why these companies would not produce some parts as the demand isn’t that high. Even if they produce these parts, it only slows the cycle time of the production process.

However, you could produce the parts you need which are not readily available by contracting the part to a small-scale 3D service. Also, this opens up a business initiative for many. You could decide to become a distributor for these parts by outsourcing the low volume production to companies like AutoProtoWay. While 3D printing car spare parts aren’t so common, it is only a matter of time before it takes over the industry.

Rapid Prototyping

Making prototypes are vital to the production process in cars. However, using the actual car components to make the prototypes could be cost-prohibitive. Coupled with the fact that the prototypes require various versions, the process would take more time. This is where 3D printing car parts come in. Unlike the traditional prototyping process, 3D printing makes the prototyping process fast and less expensive.

With 3D printing, rapid prototyping has actually become more flexible. It can take as little as a day to produce a prototype using this technology.

Custom Parts and Tools Production

Car customization is a common feature of car production nowadays. Apart from people upgrading their cars themselves, manufacturers also make limited editions of cars that could have various custom parts. However, sourcing the custom parts to use could be a literal struggle. However, 3D printing the car parts needed for the custom car could save the time and expense of other manufacturing processes.

Also, the tools needed for making these cars sometimes are not available. The manufacturers could also use 3D printing to make the jigs and fixtures needed. A large manufacturer that uses 3D printing for tooling production is Volkswagen.

What Materials Can You Use for 3D Printing Car Parts?

If you want to try DIY 3D printing, you must know the various materials that can work for the procedure. While various materials can work, we’ll only review three types that can work with almost all types of 3d PRINTERS. These three include:

3d printing materials1. ABS

Acrylonitrile Butadiene Styrene (ABS) is the most popular filament in 3D printing automotive parts. The reasons for its widespread use in making 3D printed car parts are not far-fetched. It can withstand a wide temperature range (-20°C – 80°C) for extended periods. It is also very flexible and shock-resistant. Finally, its transition-to-glass temperature is high, which means it can withstand higher temperatures than most materials when in use.

However, it is prone to warping; hence, using a 3D printer with a heated bed is advisable when working on ABS.

2. PLA

The warping of ABS could be an issue for some. If you belong to that category, then the next best material for 3D printing car parts is PLA filament. This is more suitable for 3D printers without heated enclosures and would not warp easily. However, it is not as shock-resistant as ABS, and its transition-to-glass temperature is lower.


PETG is essentially an upgrade on PLA. It is suitable with 3D printers that don’t have printer beds and is less prone to adhesion. However, it is more shock and heat resistant than PETG. Its cost is also similar to that of PLA. The only problem you might have with this filament is its occasional poor adhesion characteristics.

3D Designing Software for Making 3D Printed Car Parts

Before the process of 3D printing car parts can commence, the manufacturers must make the designs and review the virtual performance of the intended part. This is why the software used is important. Even if you’re a hobbyist looking to make some 3D printed additions to your car, the software is an important part of your production process.

Although if you’re just a hobbyist with no previous experience, you’ll feel extremely out-of-depth with these design platforms. Nevertheless, let’s get into it:

Advantages of 3D Printing in the Automotive Industry

3D printing is gradually gaining ground among automotive manufacturers due to various reasons. From its production speed to lower cost, 3D printing car parts saves the day in many ways. We’ve explained a few of these advantages below:

3d printing in the automotive industry1. Reduced Lead Times

In the automotive industry, innovations are constantly needed to bring to the market. Manufacturers want to bring something unique to their customers each time. Hence, there is a need for a lot of prototype design, manufacture, and testing. In the absence of 3D, using other manufacturing techniques for just prototyping would take a lot of time.

Also, even after prototyping, there is the need to manufacture the special tools needed. Using other techniques could also considerably slow down production. This would also contribute to the time used in making the vehicle and might sometimes deny the manufacturer’s first mover advantage. However, with 3D printing, you can make prototypes or tools within a day’s work! It’s much faster, hence reducing the lead time of parts production.

2. Realistic Concept Designs

When designing a vehicle, the software plan is the first step. However, the design can be seen on paper doesn’t mean its manufacturing will work out. This is where 3D printing comes in. With the technique, the manufacturer can have a realistic concept of design testing.

3. Design Flexibility

In car production, the car’s weight determines how fuel efficient it will be. For the car’s weight to undergo reduction, each part used has to be given an optimal weight. 3D printed car parts open up chances to do this. Since 3D production techniques are always in layers, designers can optimize each layer to give an overall lightweight vehicle, saving fuel even more.

4. Protects Intellectual Property

Keeping ideas and designs secret is quite vital to automotive manufacturers. 3D printing helps facilitate this possibility even more. Since most 3D printing production can be on-site, the possibility of the ideas leaking to a competitor is slim.

5. Cost

Making good cars at optimal costs is vital to making profits. This means the manufacturers would need the best ways to keep their production expenses under a leash. 3D printing could help achieve this goal thanks to its low production costs.
