If Only We Could Print Out Replacement Auto Parts…

Crafting a Chevy truck from paper

Unfortunately, it’s not that simple. Every component in a car is meticulously engineered to work harmoniously with every other part for optimal durability and efficiency. Car manufacturers set precise dimensions and tolerances for all original equipment manufacturer (OEM) parts to ensure flawless operation.

By definition, OEM parts are precisely what your vehicle requires.

Of course, OEM parts tend to be costly, which makes it tempting to opt for cheaper aftermarket alternatives from lesser-known companies. However, there are significant risks involved with purchasing such parts:

1. Many of these parts aren’t actually designed for your specific vehicle. Replacement parts, especially maintenance items like brake pads and oil filters, are often made to fit a wide range of cars, taking a “one size fits all” approach. The original manufacturer, which provided a bumper-to-bumper warranty, likely designed a part tailored explicitly for your car. Replacing it with a generic part is rarely a wise choice.
2. These parts typically lack warranties. If you purchase an OEM part, for instance, you'll often receive a 12-month, 12,000-mile warranty against defects. While this warranty may seem modest, it demonstrates the manufacturer's confidence in their product. Many aftermarket part manufacturers are unwilling to offer such guarantees.

That said, in certain cases, aftermarket parts can match the quality of OEM components. Premium aftermarket brands like Raybestos, Delphi, and Brembo, for example, offer high-quality replacements. However, the superior quality of these parts often means you're paying nearly as much as you would for OEM parts—and what’s the point of that? Is it truly worth taking the gamble on an aftermarket part for a few dollars’ savings?

Risking Fit, Finish, and Quality with Aftermarket Options

There’s an old adage that rings true: You get what you pay for. Every time you install a low-cost aftermarket part in your vehicle, you’re essentially betting that it will perform as expected. Will it last? Will it avoid causing other functional parts to fail? There’s inherent risk involved.

In contrast, OEM parts are guaranteed to fit and function exactly as intended. Instead of worrying whether the budget aftermarket wheel hub you installed on your SUV will fail mid-drive, you can trust an OEM hub to endure just as long as the original part.

To reiterate, OEM replacement parts originate from the same production lines and adhere to the same stringent specifications as those installed in your vehicle at the factory. This is no small matter.

Are aftermarket parts always inferior? Not necessarily. However, the highest quality aftermarket parts often command prices comparable to OEM options, and when costs are similar, OEM replacements typically make more sense.

As for inexpensive aftermarket parts, steer clear. There’s always a compromise in terms of functionality, performance, or quality.

What About 3D-Printed Replacement Auto Parts?

3D printing holds immense potential. Instead of purchasing OEM parts, you could theoretically print replacements using platforms like Shapeways or Sculpteo. Although no companies currently offer these kinds of parts, a new website promising 3D models of replacement car components that users can print themselves is reportedly on the horizon.
