Using Tough PLA at low temperatures

[QRikard 0]

The datasheet for tough PLA doesn't provide any information on the strengths at low temperatures.

Does anyone have any experience with printed items at low temperatures (down to -30 degrees C)?

 

What about UV exposure?

Personally not, but with -30° you will get problems with layer bonding.

 

Why do you want to print so cool?

For the sport 🙂

Of course printing is made at comfortable room temperature with proper settings. Results look good so no problem there (printed other stuff).
 

Question is if i can use the printed part outdoors (tough PLA) or if i need to find a better material like nylon? Moderate strain, so it should hold without issue at room temperature, but what happens during cold?

🙂 Ok, now I got it, I thought you want to print 30° lower than the specified printing temperature and was wondering why you want to do that 🙂

 

So for a part that should be used at -30° I would take something that is not so stiff, maybe PETG. But TPLA or PLA can also work, but both materials are stiff so it could happen that they are too brittle at such low temperatures. Just a guess, no experiences.
