Taulman Bridge Nylon

Post by Amedee » April 27th, 2016, 3:35 am

Hi everybody!

I am printing 'connectors' for a large structure made of tubes. As I am a bit afraid that that they could break I decided to print them in nylon which flexes more.

The quality of the print itself is very good, but I have adhesion problems.

This one came out OK, but as you can see the brim comes loose very early...


I initially had the bed at 80°C, I pushed to 95°C and it seems to be better (but does not make too much sense as it is above Tg).

As everybody seems to use glue, I used the glue I got with the printer (Blue glue stick from Staples) -- I actually never use glue on my heated bed so it is the first time I used it ;)

The nylon should be reasonably dry -- I did not 'cook it' before use, but it is stored in a dry place and there are no bubble / pops / cracks while printing.

I have to print quite some connectors (a bit bigger that the one in the video) so I cannot afford to much print failures :roll:

Any advice?
Phil.

Actually the culprit was the blue glue stick from Ultimaker...

Just used another PVA glue and all problems solved!
(Well, almost, now it is a pain in the **** to get the print off the plate :oops: )



I will carefully store the blue glue stick together with the infamous blue PLA filament from the same vendor :roll:

@Amedee, do you had any issues with the higher temp at the print head, especially at the PEEK or PTFE parts?

Not at all.

You don't need very high temperatures for Bridge (ballpark 240-245°C if my memory serves well). As long as you stay under the 250°C limit you should be on the safe side.

I printed 3 spools of bridge for this project, no issue with the PEEK, and the coupler is OK (I say OK because I never changed it since I have the UMO+ so I can't say it is like new, but Nylon didn't damage it)

FYI, just checked my GCode, and I printed everything at 245°C...

Not sure I posted the final result here:

It seems so - that's the info I found...
Amedee, could you please crosscheck - if it works, I'll change it :-)

I print Bridge with the bed at 50C, and use UHU glue stick. Once the bed cools I can usually get the prints off using a penknife to lever it off.
