<p>I need to print a rotor for a DC motor I'm designing. In the process of testing the behaviors of the motor performances, I would need a material that will not deform at a temperature range between 100 °C to 150 °C.</p>
<p>Since I don't have a 3D printer yet, I would like to know what would be the best choice for my need.
I was planning to buy an Ender 3, but I'm not sure this entry-level 3D printer will allow me to obtain the results I'm looking for. I'm excluding PLA material because I think it's the most &quot;fragile&quot; material from this point of view and for my needs.</p>
<p>My questions are:</p>
<ol>
<li>Which material should I use in order to have a 3D printed object (rotor) that will not deform at a temperature that varies from 100 °C to 150 °C?</li>
<li>Can an Ender 3 (planning to use full metal hotend and also hotbed) be used to print the filament that is heat resistant? Should I buy a resin 3D printer?</li>
</ol>
