Being nice to support people on the phone generally gets you far better support because they genuinely want to help you.</p>]]></content:encoded>

It's like driving my 1971 Volkswagen Kombi I inherited from my uncle. It's fun to drive but don't expect it to go over 90 km/h so driving it on the highway is out-of-the-question. Same with engineering filaments I want to work with. They are at the limit this printer can do. </p>]]></content:encoded>

<p>The reason being that you already had to fix so many problems that you know the printer pretty well by now? Or that enough other users had the same problem, so you can trust to get good suggestions from the forum? 😉 </p>
<p>It does sound a bit like something a Lada driver might say... 😏 </p>

</blockquote>
<p>Personally I don't plan to switch to Bambu Labs. Like @hyiger, I think I have learned enough about the Core One now to keep it running successfully. If the INDX solution enables efficient multi-material printing (eventually), the Core One will provide all I need.</p>
<p>But when it comes to recommending a 3D printer to others, the balance has certainly shifted. Some arguments in favor of Prusa are still valid: European-made, good support, open ecosystem. But the "less frills, but more reliable" trade-off no longer seems true. While Bambu Labs are certainly not perfect, they do seem to take pre-launch beta testing much more seriously -- resulting in fewer design issues even though their designs are more complex. </p>]]></content:encoded>
