Taulman 910

[rsilvers]

I think I turned off dense support layers for all of my profiles. Is that a useful setting?

alright you sold me. i really hate buying taulman since it so hit or mis but he is the only one that makes good nylon. i would print nylon more if it wasnt so warpy and hard to stick. this stuff sounds like the ticket.....maybe

rob, it lets you do really low infill like maybe 15-20% all the way to the top then dense support layers go on top of that before your part is printed. saves alot of time, materials and gets you better bottom side surface finish.

[rsilvers]

I see. I have been using 15-25% support infill - which has been fine. I can change it to 10-15 and then use dense. Ok.

[jimc]

sure, take that 10-15 then toss 3 dense layers on top at say 40-50%. slice it and you will see it in the preview

I could have used that on my current print where I added more tall support that added three more hours to the print.

I agree with Jim, I really like how the dense support gives you better surface finish on the bottom. I use 25% and then 2 layers at 75%. It really speeds up your print times if you have a lot of support. One trick I use if you have tall ,narrow support structures that have a tendency to move around (especially with ninja flex), I use support infill angles of 0 and 90 so it strengthens up the infill and ties it together for more stiffness, but does not add to the build time.

This part was done in Taulman 910 and I compared it with a similar part (on the left in the second picture) in 645 that I have done recently. The 910 is significantly stiffer and gives you that injection molded part feel my customers have been looking for in a prototype. I also noticed less stringing and ooze compared to 618 and 645. I will dye this part tomorrow and see if it takes up dye as well as 618 and 645.

I think you can turn down your 25% to 15% and not notice any difference. I am using 25% with no interface layers for when I want high quality and 15% most of the time. I will probably go to 10% and and three interface layers.

I didn't know about this multiple infill angle thing. I think I need that. I am excited to change these settings once my print finishes.

This is 0, 120, and 240 for the angles at 10% support infill.

You can do it for infill also. I think I will do 0, 90, 45, 135 for infill.

Yes, the multiple infill angles work great for both support and part infill for those of you that have not tried it.

My thoughts on the Taulman 910 were that a material this stiff would be brittle, right? Can you do this with PETG, ABS, or PLA? I don't have much experience with these other materials, so I thought I'd ask. The below ring is a 1" OD x .125 wall x .25 thick. I collapsed it onto itself and then stretched it back out without any crazing (like ABS) or breaks. I was amazed. I did it multiple times, no delamination or breaks. I would expect this reaction from 618 or 645 as they feel tough and flexible after printing, but not in a material that feels as stiff as ABS, PLA, or T-glase. This was printed with .35 nozzle, .4 extrusion width, .2 layer height, at 3600 mm/min. One thing I have not done yet is see how 910's stiffness is affected by heat.
