Qidi Plus4, early access, news
🕑 Added 2025-03-20 15:33:41 +0000 UTCHello, Just to inform you about my latest activity.
Qidi Plus4 review video is finished, public from tomorrow, but you can find it in the 3D printing playlist. Soon I can start PPS filament testing too.
What is already printed: Creality PPA-CF, Sunlu PC-ABS, Qidi 3xPPA based filaments (CF, GF and Core). Ah, that creep test is so sloooow. Beside Creality PPA-CF, I also bought few other filaments too: PTFE+PETG (Teflon+PETG ??), Graphene filaments (PLA and PETG). I also ordered eSun PET (not CF) to see how it performs compared to PET-CF..

Yes, new post, published few minutes ago..

Igor, Is there a new link for the spreadsheet that includes the creality ppa-cf? I can't seem to find it. Thanks

Looking forward to more technical filament tests. Still hoping you'll test add:north PC-CF one day, pretty sure it is at least stiffer than anything you tested until now.

But because PC-ABS is an "old material" right now I am trying to replace it with CPE HT and maybe PETG-PTFE. I am looking forward to your test of the PETG-PTFE.

Because ... besides the "Styrols" and "Bisphenols" ... PC-ABS has a uniqe blend of material properties: Hard surface, stiff, still bends, good impact resistance, ... aaand ... what almost all materials outside of ABS and ASA lack, it does not squeak and crackle "stick-slip" in friction joints, think boom arms and box lids.

I saw that in your Qidi Plus4 test prints you were having problems with PC-ABS. I have been down that road and had to throw away 4 different brands of that material, because my enclosed Prusa MK4 with active heating in form of a hairdryer+thermostat and chamber temps of around 45° C just could not prevent warping. .... But there is a PC-ABS blend out there that has been printable, even on my old Ultimaker 2, and this is the BASF Ultrafuse PC/ABS FR. Give it a try! It can be difficult to find. I used to buy it here: https://www.igo3d.com/BASF-Ultrafuse-PC-ABS-FR-Schwarz-175-mm-750-g

Friction test is a great idea! Also, I’m really looking forward to PPS-CF tests.

You might need a new test of PTFE+PETG to compare its friction coefficient to other filaments. As always, thank you for your testing that informs our purchasing decisions.
