The technological revolution is reshaping traditional industrial processes and the automotive industry stands at the forefront. Amidst the revolution, 3D printing technology has significantly modified the vehicle manufacturing process. 3D printing with an ability to transcend conventional manufacturing constraints has grabbed the attention of all the leading automobile brands. Many brands are already using 3D-printed auto parts in their vehicles.
Let’s dive a little further into the usage of 3D printing in the automobile industry and dissect what it brings to the table for the users.
What Is 3D Printing in the Automotive Industry?
The usage of 3D printing in the automobile industry enables engineers to design lightweight, sustainable and more customised auto parts. However, there is still time to see fully printed cars on the roads, the parts are commonly used and available.
Here we have mentioned the complete process of 3D printing in the automotive industry.
3D Printing Process
The process of 3D printing starts with 3D modelling software. The software is used to design prototype vehicles and different auto parts. For instance; an engineer is designing a futuristic car door, and the software assists in designing the whole frame and other car door parts that will be used.
After designing, the engineers are required to select the printer settings such as; thickness, density and print speeds. Once done with the software, preheat, recalibrate, load the printing material and start printing.
Materials Used for 3D Printing
Unlike carbon fibre car parts, 3D printers use different types of materials to manufacture car parts. The type of material used depends on the strength and resistance required by the auto part.
Following are some commonly used materials for 3D printing auto parts.
- Polypropylene: It is used to print plastic auto parts such as steering wheels and dashboard buttons.
- Polyamide 6: It is a flame-resistant material perfect for car engine parts. Whether it is a cylinder head or piston, Polyamide 6 is suitable for all.
- TPU: TPU is known for its higher resistance, flexibility and absorption capability. That said, it is perfect for printing parts like air filters.
- Nylon PA11: It is a sustainable material extracted from plants. Therefore, it is often used for making lightweight recyclable auto parts.
Pros of 3D Printing
The 3D printing of automotive parts has become a driving force behind a myriad of useful car features. Whether it is reducing vehicle weight or frequent prototyping, 3D printing can help in all. That said, here we have listed some practical uses of 3D printing in the automotive industry.
Innovative Design
3D software allows engineers to design complex car parts that are otherwise nearly impossible to design. This additive technology leverages engineers to limitlessly experiment with car design.
Along with the innovative design, 3D printing has also altered other steps involved in the car design process. Auto prototyping is a major part of vehicle design that is divided into multiple stages. Traditionally, prototyping can take months or even years to convert an idea into a prototype. However, the latest design and printing technology have reduced this time to weeks.
Lightweight Car Parts
Automobile brands utilise different techniques to reduce the overall car weight. A lighter car consumes less fuel which increases the vehicle’s efficiency and performance.
The 3D printed automobile parts are generally lighter in weight contrary to metal parts. Moreover, the printing software allows designers to experiment with innovative design which reduces the number of auto parts and increases car aerodynamics.
Reduced Production Time
3D printers have higher machine efficiency and can provide car parts on demand. This eliminates the need of having inventory stock and waiting for the factories to supply spare parts.
Using a 3D printer not only saves money but also reduces production time. Furthermore, manufacturers’ supply chains remained unaffected by the global crisis and economic situations.
Higher Sustainability
Reducing the carbon footprint of vehicles and using sustainable production methods is the vision of all the leading automobile brands. 3D printing can aid this mission in multiple ways. As mentioned above, some 3D printing materials are derived from plants making them biodegradable and recyclable.
The higher efficiency of the machine reduces waste production, electricity consumption and fuel used for logistics. Furthermore, the printer itself consumes less energy making it suitable for the environment.
More Customisation
Since 3D-printed auto parts are not mass-produced it allows more customisation options. Brands can customise any spare part to increase vehicle efficiency as per the customers’ demand. This will also help in reducing the manufacturing time of vehicle special orders. For instance: if a customer demanded a customised engine with parts of different configurations, brands can manufacture a car as per the requirement and deliver it in less time.
This was all about 3D printing in the automotive industry. 3D printing has increased the efficiency of car designing and manufacturing processes. That said, the 3D-printed parts are more eco-friendly, durable and lightweight.
