<p><strong>Here is the context</strong><br/>
I've got an old car for which I have a small plastic piece who is broken. As it's an old car and a very specific piece, I can't find it anymore. So I was thinking about 3D printing it.</p>

<p>My problem is this piece is on the carburetor, so close to the engine. This means, it can heat a lot, close to 90-100&nbsp;°C.</p>

<p><strong>My question</strong><br/>
Do the pieces created with the common 3D printing techniques melt at 100&nbsp;°C? If yes, what kind of other 3D printing technique can I use?</p>

<p>Here is the piece I want to recreate (sorry for the bad quality), the scale is in cm.

Depending on the exact mechanical load and material used to print, you might get away with 100 °C.
Next to the melting temperature required to print the material (which will always be substantially higher than the maximum useable temperature!), you probably also want to have a look at the glass temperature of your specific material. Around that temperature your material becomes soft (rubber like) and can deform permanently when cooling down again. Chances exist that under a considerable mechanical load, the part will deform at even lower temperatures.
Maybe it would help to post a picture or describe the exact component you're trying to replicate. It might help in finding an alternative solution. (E.g. carving out of say PEEK to say anything.)
