<p>I recently ripped a piece off of a nitro RC car I have. Seeing as I cannot find a direct replacement at the moment, I modeled it and it seems easy to 3d print.</p>
<p>My main concern is how heat resistant the replacement will be - this is a combined structural/exhaust heat deflector piece.</p>
<p>I've previously known about 30-40% steel infused PLA, but looking at the reviews/overviews everyone states there is no structural advantage to steel/metal infused PLA.</p>
<p>That being said, are there any benefits at all, aside from styling? Temperature resistance, conductivity, stiffness, toughness?</p>

A raft is an aid for adhesion if your print object geometry or choice of filament requires you to use it, but as far as printing PLA, a raft is generally not needed.

After some cooling, the model may come off by itself. As the plastic cools, it hardens, losing the tackiness needed for the layers to adhere.</p>\n</li>\n<li><p>CLEAN THE PLATFORM</p>\n<p>This may not help with current printing, but if your platform is clogged with old adhesive, then it\'s probably time to clean it out. Future prints may not adhere as firmly. If the print is still stuck, run <a href="https://www.craftyhangouts.com/best-3d-printer-for-beginners/#product3" rel="nofollow noreferrer">it</a> under a stream of hot (not boiling) water and carefully use a spatula to remove any adhesive on the surface.</p>\n<p>After printing, make sure the platform is clean and inspect the surface of the steel. If there are indentations, turn the glass over and use the smooth side. If both sides show signs of pitting, replace the glass.</p>\n</li>\n<li><p>PUT IT INTO THE OVEN</p>\n<p>There are times when hot water doesn\'t help if you have a glass or other heat-resistant surface with no plastic or electronics and you can take it off the printer, and put it in the oven. Set the temperature to 100º and then use a spatula to see if you can remove the model. If it does not work, increase the temperature to 120º, leave for five minutes and try again. Raise the temperature until you remove the model.</p>\n</li>\n<li><p>DO NOT USE CHEAP PLASTIC</p>\n<p>In many cases, cheap plastic is a false economy.</p>\n</li>\n<li><p>MAKE SOME HOLES</p>\n<p>By creating several holes in the surface of the print base, you can avoid sticking caused by too much surface contact.</p>\n</li>\n</ol>\n<p>Hope these tips help you :)</p>\n'}]
