NomisRC's Printing thread, Ups and Downs

[nomis38]

I figured I'd start my own thread of good and bad experiences in the 3d printing game. Some things I want to post just don't fit on other threads and I don't want to keep starting multiple threads. This will only be for my highlights. Major achievements and major failures, nothing in between.

I wont go backwards only forwards. I have done a lot throughout the years of printing but who cares.... right... On with the thread...

So i've only tried TPU a couple times, always with failure @Dutch helped me understand what google literally would not tell me at all. It's 100% about speed. I'd like to elaborate my findings on that. With that knowledge I had a successful print, got cocky and ramped speed up to high and got failures.

A few hours ago I set everything on my BIQU BX back to 20mm/s, upped the heat to the hot-end some, and tried TPU again. My N4M is busy and cant be bothered lol....

So far so good. And for me the issue with printing at a faster speed is with extrusion. The filament is so flimsy that if I extrude to fast my "pullies with teeth" (i'm sure they have a name) that grab the filament strip the filament and then just cause it to jam and wad up above the hotend. I'm assuming this is everyone's issue with fast extrusion of TPU but I have only really successfully done this on 1 printer that it seems no body but me has, aside from a ton of people that upgrade their ender's with bigtree tech boards and extruders so they are basically BIQU's .

I am printing the long awaited Mojave bumper supports in TPU 9 hour print. For me if it fails it fails within the first couple layers and its well beyond that now. Maybe this old slow printer will have a new task and that is doing what it does best. Print things slowly but surely.

This is a big deal to me so its definitely a highlight in my 3D printing endeavor. I've always been annoyed not being able to print in TPU. I hope I cant get it down pat, and this is why its being mentioned in this thread.

Awesome!
Best of luck in getting this printer dialed in for TPU.

Def lookin like its all about extrusion speed for me. Im glad I now know the details of why I have to extrude slowly and its not the reason I thought. I thought it would come out fine just get messy.

It's on layer 9 now and looking solid.

Ignore the print times, octoprint lies, Fluid does the same. The slicer is much more accurate.

That link is rad. It looks like it's printing well!
What durometer is it?

Well before I left, I noticed one of the parts was free from the bed, but the other is still stuck well. Hate to cancel it now so just left it .

The woes of 3D printing . Assume print failure and you'll never be let down

Ok from viewing the link it looks like it finished and was successful with one of the parts so thats good.

Edit:
@Relimar - This is the filament I have, not sure on the Durometer of it.

95A according to the link. It's 3D printed rather than a molded, homogenous structure, so mileage may vary.
Here's a durometer chart

I gotcha... Well i am familiar with shore as I used to race touring cars with foam tires way back when.

Question: "for anyone that knows"
So im curious when printing TPU, how does it do when something needs supports printed?

Not sure why but in my head, this is an issue, maybe it's not.

 

[nomis38]

Ok one good one and one trash one. Getting the other going now.

She cleaned up nice for being as stringy as it was.

That looks really good, glad you're having some success with TPU.

I'm running the part that failed now at 35mm/s and it seems fine so far... YaY!!

Also omg 2kg spools are deceptive. They are so big in the center they make you think you have way more left then you actually do. Being this thing can chew up 1kg in a day it seems imma need a lot more filament haha.

 

[nomis38]

So it wadded up in the extruder at 80% finished lol... Guess 20mm/s it is. I need to print off other things so the final Mojave mount is gonna have to wait.

TPU is not the most friendly material to work with.

Well this is definitely a up in the game of printing for me. Really any upgrades are i guess.

New BIQU BX extruder got installed and I must say its gorgeous. They really do know how to make nice, quality, beefy 3d printer parts.

Not a single piece of plastic on it, cept the fan haha. All aluminum casing, all steel gears, machine work is super nice as usual. I really love direct drive extruders. Even the lever to input the filament..... Yup metal...

She is a little chonky but all direct drives got some weight to them. But this along with a software update will get the Sturdy and Trusty BIQU BX to 100-150mm/s speed. The stock printer was already rated for 50 - 80mm/s, the new one is rated for 100-150mm/s so essentially im just updating to the newest version as mines almost 5 years old now. WooHoo!!

You need a 5Kg spool...
That'll be good to hold you for a week.

They do make 35Kg and 50Kg spools too.

Oh dang... Yeah honestly the bigger the better, I'd just need to make a little rack for it. I get sick of swapping filament and the big printer really only uses black.

100mm/s - Those are some thin lines too. Easy to mess up if the speed is to fast. It did it like a champ.

Very nice..

2 of the 3 pieces are done on the Din Djarin Helmet.

First round of sanding done as well.
