Why choose PETG rather than PLA for white housings and panels?
White housings are usually functional parts, and there PETG beats standard PLA: the glycol-modified copolymer fuses layer to layer far better, so a panel resists impact and moisture take-up instead of cracking along the layer lines, and it prints in the 230-260 C window without a heated chamber or a high-temperature hot end. It is not a high-temperature material: above roughly 70 C service temperature, specify ABS or PC instead.
