From smartphones to IoT devices, electronic enclosures play an important role in protecting sensitive electronics and ensuring their optimal performance. However, finding the right enclosure for a specific device can be a difficult task. Fortunately, with the rise of 3D printing, creating electronic enclosures that meet your product requirements has become easier than ever before.
In this article, we’ll explore the best 3D printing method and suitable filaments for creating high-quality electronic enclosures. We will also provide insights on how to 3D print electronic enclosures, the most accurate 3D printing method, and the material used for printing.
Methods for 3D printing electronic enclosures
When it comes to 3D printing electronic enclosures, there are several methods available. Some of the best methods for 3D printing electronic enclosures are:
Fused Deposition Modeling (FDM): FDM is the most popular 3D printing method for electronic enclosures. It involves heating a thermoplastic material until it melts, then extruding it layer by layer to create the desired shape.
Stereolithography (SLA): SLA is a high-resolution 3D printing method that uses a laser to solidify liquid resin. SLA is ideal for creating enclosures with intricate details and high precision.
Multi Jet Fusion (MJF): MJF is a 3D printing method that uses a fusing agent and a detailing agent to fuse layers of material together. MJF produces enclosures with high resolution and strong mechanical properties.
Here is a detailed comparison of the methods that are most suitable for printing enclosure:

Limited raw resolution
Suitable for electronic enclosures that require high strength and durability, such as those used in aerospace or defense applications.
Suitable materials for 3D printing enclosure
To create a successful electronic enclosure using 3D printing, it is important to choose the right material. Here are some of the suitable materials for electronic enclosures, along with their pros and cons:
ABS (Acrylonitrile Butadiene Styrene): ABS is a commonly used filament for electronic enclosures due to its strength, durability, and ability to withstand higher temperatures. It also has a high level of impact resistance and can be easily post-processed through sanding, painting, and gluing. However, it requires a heated print bed and a well-ventilated area due to its strong odor when printing.
PETG (Polyethylene Terephthalate Glycol): PETG is another popular filament for electronic enclosures due to its strength, flexibility, and resistance to impact. It is also a food-safe material, making it a good option for enclosures that will come into contact with food or beverages. PETG is easy to print with and does not require a heated bed or ventilation, but it may be more prone to warping than other filaments.
Nylon: Nylon is a strong and durable filament that is also lightweight and flexible. It is resistant to impact, chemicals, and high temperatures, making it a good option for enclosures that will be exposed to harsh environments. However, it requires a higher printing temperature and a heated bed, and can be difficult to print with due to its tendency to warp and absorb moisture. If MJF 3D printing is deployed the most used Nylon form is PA12 and PA11.
TPU (Thermoplastic Polyurethane): TPU is a flexible and rubber-like filament that is great for creating enclosures with a soft-touch finish. It is resistant to impact and chemicals, making it a good option for enclosures that will be exposed to rough handling or chemicals. However, it requires a lower printing speed and may be more prone to stringing. TPU from Lubrizol is offered in MJF 3D Printing
Post-processing requirements will vary depending on the desired finish and application of the electronic enclosure. Common post-processing techniques include sanding, painting, and gluing, as well as adding additional components such as screws, hinges, and latches. It is important to consider the intended use and environment of the enclosure when selecting a filament and determining the necessary post-processing steps.
The most suitable combination of methods and filaments for printing enclosures
For printing one or a few numbers, the combination of FDM with PETG or ABS filament can be used for faster and more reliable 3D printing of electronic enclosures. FDM is a fast and efficient method that can produce high-quality parts with good accuracy, while PETG and ABS are durable and have good temperature and impact resistance, making them ideal for electronic enclosures.
Additionally, both filaments have a relatively low cost, making them a cost-effective option for producing electronic enclosures in larger quantities. It is important to note that the speed and reliability of 3D printing electronic enclosures can also depend on the printer settings, the design of the enclosure, and the expertise of the user.
Please note for higher or serial production MJF 3D Printing is the best option in the market.
In conclusion, with the right combination of method and material, you can achieve faster and more reliable electronic enclosures using 3D printing. So why wait?
