Selecting the right material for a 3D printed project box is crucial, especially when it houses sensitive single-board computers (SBCs), relays, and sensors. PETG is indeed a great choice due to its strength, durability, and resistance to higher temperatures, which can be beneficial for electronics projects that may generate heat. For projects requiring more wear-resistant materials, SLS nylon is recommended, especially for enclosures that will be opened and closed repeatedly. It’s also important to consider the design aspects of the box, ensuring a minimum wall thickness of 2 mm and a tolerance of 0.5 mm around internal components for optimal fit and function. For those looking to experiment with different materials, PLA can be a good starting point for prototypes, while TPU or TPE might be chosen for flexible parts. Ultimately, the choice of material will depend on the specific requirements of the project, such as the need for thermal stability, mechanical strength, or aesthetic appeal.
