Dialing in Taulman 910

[JohnInOttawa 103]

With all of the printing of PPE these days,  the workflow feeding the UM3 has allowed some time to get some other projects done.  Along the way I have been trying filaments that I had long wanted to use but didn't want to unpackage until needed.  I've run some Nylforce CF (nice stuff but takes tweaking for dimensions), Murano (super strong, dimensions also need tweaking),  Cheetah (which has really hit a few bullseyes) and now, Taulman 910.

 

I must admit that I have not mastered Nylon, at all.  I've looked at all the material I can including gr5's excellent tutorial.   I have some Ultimaker black Nylon which I can get OK (as in only slightly warped) but reasonable surface and dimensions out of.  Today I tried some Taulman 910, as I wanted to see how it did in terms of warping and strength.

 

Warping seems decidedly less than the Ultimaker nylon, but for my project (a hinge with a vertical barrel and horizontal mounting plate, so circular holes  on two planes normal to each other), it has been a challenge, with each tweak seeming to trade off print quality, dimensional accuracy and strength.

 

The primary dimension that I really can't mess up is the barrel, as this rotates on a hinge post.  My preference, then, was to print this with the barrel and mounting plate vertical, without supports for the two small holes through the plate.  Whereas I could get away with this using the Ultimaker nylon, the Taulman prints less evenly, resulting in a wavy vertical edge and warping along the narrow contact with the build plate, even with extensive brim. 

 

Lying the mounting plate flat yields excellent results on the mounting plate, better than I saw when printing with Ultimaker nylon and no warping at all.  Unfortunately, the barrel suffers.  Using the 910 as support material to protect roundness results in a bonded block of nylon support that can't be removed, so I am trying the print now with PVA support.  We'll see.

 

Right now, print settings are up to 260 for the nozzle, 70 for the build plate, 40 mm/s for the speed.  PVA coating on the print bed.  I've be grateful to hear the experience of others running 910 and learn what has worked best for you.

 

All the best, stay healthy!

Where are you with this?

[JohnInOttawa 103]

I found the best results were with using a different colour of nylon as support material instead of PVA.  I suspect an issue was that the nylon printed too hot to work well with soluble support. 

 

For the project I mentioned then, I had the 910 printing the plate flat with a lot of brim, then black Ultimaker nylon used for support inside the barrel and no fans running.  The support came out fine and I just reamed out the barrel lightly to get it to final shape and tolerance.  I'm happy with this stuff and it is really, really strong.

 

I've also run a hybrid model with the Taulman 910 as the skin and Nylforce inside for strength.  Bonding is not great between the two so I have to arrange a mechanical linkage in the model.

I went ahead and also purchased Taulman's SAC 1060 for supports. It's specifically designs as a support material for nylon. What sort of setting changes did you make? I thought I would duplicate the Ultimaker Nylon profile and then adjust from there.

[JohnInOttawa 103]

I don't think I made any further changes than what's noted already.  Since I used Ultimaker nylon as support I used stock settings for it, and then the temperature and print bed changes as discussed.  And of course closing up the print chamber to keep the heat in.

 

Would be interested in hearing your experience with the SAC 1060.
