Nylon (Page 8 of 9)

Drying it out in the oven at 200F for a few hours helped considerably!

Very nice. Great application with the gas can.

hello everybody, I just got my shipment of taulman 618, i've actually been able to print a few test boxes, but they do not want to stick what so ever. I just upgraded to a glass plate with blue painters tape, but to get the abs to stick I had to use slurry. Will this reduce the nylon's ability to stick? Also I can't really get the nylon to stick very well yet, do I just keep increasing the brim and have a fatter width to the first layer? Currently I'm running the bed at 95 and the nozzle at 210, 215 starting acting sort of weird. I'm also going to try drying the filament out, its popping and hissing a lot and there are plenty of bubbles in the thin walls of my 1 layer test box that did do so great... (the layers didn't adhere so magically as claimed... yet).

just to check back in, i dried the whole rolls in the oven at 200 degrees for a few hours, deformed the spools a little bit lol but they're fine. I'm running the nylon right now and its doing amazingly well! I'm running 210-215, i think 215 is getting better layer bonding, and the bed with the top and door off at 85 degrees. i usually have a layer height of .325 over my .3mm settings for abs and i'm back to that for nylon. I think my extrusion width is like 135%, may turn it down even more. I apply abs slurry pretty heavily for abs prints and then i just clean it with pure acetone to for the nylon and its doing great right now! perfect adhesion, coming through perfectly smooth, no bubbles or anything! haha i think some swapped the rolls i had yesterday because its behaving completely differently lol

Keep in mind that the nylon works better as your temps get higher.  Obviously without an all metal hot end this is a limitation for some but the differences I noticed between 230C and 245C were significant.

Thanks for linking kind sir!

So guys got my Nylon 645 going today. Got a couple of questions.

What sort of layer adhesion should I expect from this stuff?
Stock hotend sd3 printing at 210 on RH.

Basically I printed a small 15mmx15mm tower no fill with a single wall. Printed nice. Wall thiknes is really close to expected. But I was able to just pull and separate the layers. That was at .3mm at .2mm it seemed a bit better. I could twist the tower no problem but when I bent it the layers broke apart. is this about normal for this print or should this stuff adhere like its one piece?

Thank you!

One other thing, are you printing in an enclosure?

If not you might think about making something as it does help a bit.

Changing your extrusion multiplier(in slic3r) will increase flowrate. Just try a little at a time.

I print my nylon layers at .25-.3mm

The real key as ronsii said was that you need more heat to really get the most out of nylon.

Printing a lot on the glass and elmers glue. Working great!
