All right! I will give you a nice explanation in the appropriate style, as you want it – easily understood, with icons and 2 pictures of deformed 3D printed parts.
Here is my suggestion:

Attention to 3D printed plastic parts! ☀️?

Our 3D printed products are made of high-quality plastics – butplease notethat you are sensitive toHeatanddirect solar radiationcan react!

❗ Why?

• Plastic parts can bedeformation, softeningor evenmeltingif they:longer than 60 °Care suspended.
• Direct Sun(e.g. in the car or on the windowsill) can easily reach temperatures above 60 °C!

The melting points of our materials

? PLA(polylactide)
Glass transition temperature:~ 55–65 °C
→ Will already be inSolar heatsoft!

? PETG(polyethylene terephthalate glycol)
Glass transition temperature:~ 70–80 °C
→ A little more heat resistant, but sun can also be critical here.

? ABS(acrylonitrile-butadiene-styrene)
Glass transition temperature:~ 100–110 °C
→ Better suited for higher temperatures, but direct heat remains a risk!

Possible consequences?

• Deformation
• Material cracks
• Loss of stability
• Complete melting or gluing

Guarantee Notice?

InDisregardof these instructions (e.g. storage in extreme heat)we do not assume any guaranteefor damage to the products.
