Hm, komisch - das billige Aldi-Haarspray hat bei mir überhaupt nicht gefunzt. DDP? Was genau nutzt du denn da?

CPE+ ist inzwischen mein bevorzugtes Material für mechanisch belastete Teile. Was die Haftung angeht, so habe ich in 100% der Fälle Erfolg mit 3D-Lac-Spray pur auf der Glasplatte. Gerade in Kombination mit CPE+ ideal, denn die Drucke lösen sich nach dem Erkalten der Druckplatte quasi von selbst ab. Das Spray kostet zwar rund 11,-€ pro Dose, ist aber sehr ergiebig. Eine dünne Schicht reicht.

afaik BioFila from TwoBears should be food safe. They also provide BioFila that is said to be stable up to 130°C. It's some PLA-derivate and they are very keen on sustainability. They even do not use sealed plastic bags for their filament - which I personally think is a bit too sustainable, but okay. For Taulmann's Nylon 910 it's explicitly stated to be FDA-approved.

So what are your settings, Yousef?

I always encounter problems with BVOH - it dissolves fast, yes. But not completely. There are always some remains that are hard to remove. Even with a powerful Ultrasonic-Cleaner. I must say that as of current the Ultimaker PVA works better for me. Also, BVOH works nice with PLA and the like but does not work good with ABS.

Wow - you sound so very convinced, I think I will try what you suggest. Thanks.

But the UM3 will still not work with just one print core installed - even if the print does require only one print core... So it certainly does not help that cura is so intelligent to recognize that you only use one nozzle...

This is certainly not related to the size of memory, my friend. Did you read what I wrote? Completely? I did write about processor load...

From what I saw in the prints I would agree regarding ringing. Yes, that is for shure as good or bad as it was with the R3D N2. What a pitty.

I wonder, how that works, kman. If you have a 0.4 mm nozzle and say it's 0.26, wouldn't that lead to a massive overlap of lines? And teh other way around I would suspect bad to no adhesion between the lines in the horizontal direction?

Well, for me the UM2 was no option since I need a dual extruder and did not want to experiment with tinkering on the UM2 to get dual extrusion. Compared to the printhead of my former printer, the R3D N2, the printhead of the UM3 is still a lightweight! Just the Direct Extruder of the N2 weights close to 800 gramms... So I would think that the UM3 should be able to go much faster. Is the printer/Cura somehow protected against to high acceleration/jerk values? Because I would like to see how the prints look like when I increase them - but I am cautious not to kill the machine...

SMH - you may missed to include the pictures;-)

So when using a Solex3D PrintCore with say a 1 mm nozzle I would set Line Width (under "Quality") to 1 mm and that's it? And no influence of the "Print core" selection in Cura (e.g. leave that at AA 0.4)?

Well, certainly, that's the advantage of being able to change nozzles. Any experience regarding print quality/reliability/ease of use of the Solex3D-Printcores? Are they comparable with the original ones or do even have advantages here?

Thanks, gr5. So despite the advantage that I can change the nozzle size of the print core - what other advantages do the Solex printcores offer?
