PLA, PETG, ABS or ASA: which 3D printed material survives a car in UAE heat?
Car cabins in the UAE get far hotter than the air outside. Here is how each 3D printing material holds up, and which one we use for parts that live in the sun.
Why the material matters more here
A car parked in the UAE summer sun heats up well beyond the outside temperature, and the dashboard gets hottest of all. A plastic that is fine at room temperature can soften, bend or warp there within a day. So for car parts the first question is not colour or price, it is how much heat and sun the part will see.
PLA: fine indoors, not on a dashboard
PLA is the most common printing plastic. It is stiff and prints cleanly, but it starts to soften at around 55–60 °C. That makes it a poor choice for anything on a dashboard or near a window. We use it only for parts that stay cool, such as items kept inside a closed console.
PETG: tougher, for parts out of direct sun
PETG handles heat better than PLA (it softens at roughly 80 °C) and is less brittle. It suits cabin parts that are shaded, like holders low in the footwell or inside a door pocket.
ABS and ASA: for heat and sun
ABS and ASA both hold their shape to around 100 °C, which is why car makers use them for interior trim. The difference is sunlight: ABS fades and turns brittle under UV, while ASA was made to stay outdoors. That is why most of our car parts are printed in ASA, from dashboard mounts to running board guards and intake scoops.
Resin: for fine detail
Resin prints show the finest detail, which makes them good for badges, models and small precise pieces. Standard resin does not like long hours of sun or heat, so we do not use it for parts that live on the dashboard.

Tell us where the part goes in the car and we will recommend the material. If you send a custom order, we confirm the material with the price before anything is printed.
