I have several testings done in the last two weeks to find out which surface can be used for the Nylon-CF15.
It was a long trial of try and fails,but mostly fails.
Testprinter was the Creality CR-10, heatbed temp. between 50° C and 90°C, nozzle temp. between 240°C and 260 °C.
Here are the list of fails:
buildtak (pretty surprised that it did not work)
On all the above ones was the wharping on my testframe enormously and all this surfaces can´t handle it good enough for my taste.
But keep in mind that this can differ from 3dprinter to 3dprinter and/or for the entire enviroment around the Printer. All this affect the succes or can be a responsible for a fail.
So i was only share my persanally expirience on my travel to get the best possible solution for me and my 3Dprinter.
Anyway, the good thing is that i have found my solution finaly.
The best adhesion I have achieved with sandpaper 280 followed by the classical BlueTape.
If your Printer is very exactly callibrated and the nozzle Z axis space between printbed & printhead are also right, then the print sticks very well on the bed.
Unfortunately the wharping can be so strong that the bluetape stripes lift of from the heatbed.
It works sometimes but not everytime so it´s always a challange with unknown result.
Next test goes to the sandpaper with different granulation between 180 and 1000.
After my first testing on 600 sandpaper i was surprized how good the nylonCF15 Carbon stick on it.
The downside of this was it pastet to much and the sandpaper tear of together with the print.
To regulate the liability i reduce the granulating step by step and have stopped at 280 so far.
On this granulation it works very well for me but provided that the space between nozzle and printbed is quiet perfekt. After cooling down the heatbed you can carefully loosen the printing without tearing of the sandpaper.
The easiest way to stick the sandpaper on your printer bed is double sided duct tape.
I recommend that you paste the entire Sandpaper sheet on the backside with the duct tape and then paste both to the printbed. In that way you can be sure that the wharping not lift the sandpaper.
Print settings that works fine for me are:
250°C on nozzle
50°C on heatbed
up to 50mm/s
Filament: Nylon CF-15 Carbon
I hope my little travel can be usefuel for you.
