<p>I am in college and am doing a team competition to print PPSU filament, and get the best results. This is being put on by the Solvay company, who makes the material. Our team signed up and the university bought us an <a href="https://www.intamsys.com/" rel="nofollow noreferrer">Intamsys</a> <a href="https://www.intamsys.com/funmat-ht-3d-printer/" rel="nofollow noreferrer">Funmat HT</a> 3D Printer, which said it was capable of printing PPSU. However, the company doing the competition did not release the information that the bed plate must be a high temperature to avoid warping (Greater than 200 °C). However, our plate only reaches a temperature of 160. Does anyone know of any aftermarket heaters that would work with this printer?</p>

<p>Maximum temperatures according to Intamys: Chamber 90 °C, Magnetic Build Plate 160 °C, Extruder 450 °C</p>

So that would correspond to an increase from 12 V <em>at the bed</em> to 18 V.

Obviously this leaves a risk that the bed will be damaged, but I think it is better to aim for a steady load rather than pwm and a higher peak energy than necessary.</p>\n'}]
