I've made decent progress with my airfoil, but I still have one problem. How do I prevent Bambu Studio slowing down to a crawl for the top layers? At the moment the top layer of the mount slows down to 20 mm/s. This leads to a too long layer time, too much cooling and poor layer adhesion for that specific layer. I can't seem to spot the setting that would affect this.  Edit. Oh FFS, it seems that somehow I had ironing on at the "Object" level.

The filament can also have settings for minimum layer time for cooling. In other news: finally used my PEX sheet and daaaaamn poo poo is shiny.

I think this is now good enough to be used. Next up would be the 6 other sections of the wing. This section is 250 mm tall. The big holes will get aluminium tubes. The small hole a steel wire that pulls the whole thing together and glue between the section. Thread inserts for the mount and the end plates. A flat-pack wing you could say.    The process has been to put blankets on the printer. Pre-heat by setting the bed to 110 °C for an hour or two. 280 °C nozzle, 100 °C bed, 60 °C chamber and keep layer times low to get good layer adhesion. Layer adhesion seems more important than e.g. number of wall layers for strenght. After the print is finished I set the bed temperature to 100 °C and leave the print on the plate for 4 h or so to let it cool slowly.  Moving to larger airfoils, the flow rate may be more limiting to the print size than the bed dimension because of the need to keep the layer times low. There might be a case for the expensive E3D high flow nozzle to be used. DoLittle fucked around with this message at 08:53 on Jan 18, 2024 |

I have had really good results with the kind of reinforcement you're using there. Especially adding external compression to back up the layer adhesion

Curious to hear from others' experience if they've swapped in a 0.2 mm nozzle on their Bambu P1S.. I figured it'd be fun to try out the CMYK lithophanes, so I bought a 0.2 mm hot end to get the suggested level of detail. What I didn't expect was that with the fans running, the extruded filament is so thin that it flutters wildly during the colour swap purge and catches on the edge, piling up around the nozzle instead of heading out the poop chute:  Incredibly, the nozzle wipe did take care of it on all but one change where a blob made it back onto the print bed along with a small string of detritus:  It gives me terrifying flashbacks to the MakerBot Cupcake days and waking up to a solid mountain of plastic engulfing the entire hot end, but to its credit, everything did work out fine in the end:  I just.. this can't possibly be the normal, expected behaviour with a 0.2 mm nozzle, right?

I did some light internet searching and didn't see other people complaining about it so I figured it was isolated. Hasn't ruined any of my .2 prints so far but definitely feels like it could. I did print this purge chute extension which doesn't solve the main issue but does seem to lessen the chance that unwanted material makes it onto the plate.

I am SO spoiled by my AMSssesseesss. I have a P1P with two hooked up to it, and another P1P and a P1S each with one of their own. Actually currently printing something that's going to burn off two partial rolls and finish off with a third fresh one. It's the friggin' Easy Button of Printing.

Bin/table/liquidation store went crazy today with filament. Took home over 16kg of filament at $12/item. 1 box of 8 sunlu PLA 230g rolls in a variety of colors, 2 spools of sunlu PLA, 1 spool Anycubic PLA, 2 spools of overture PLA, 2 spools of Bambu basic PLA refills (looks like they cut the zip ties off and put them back in the box so those will be respooled), 1 spool poly maker PLA, 2 spools elegoo PLA, 1 spool of mystery PETG, 3 spools of ender PLA. Mostly black and white which is fine as well as some nice blue and reds and a transparent. Pretty decent deal at about 11.25/kg for overall decent brands

Boner Wad posted:It really sucks that the AMS doesn't work with TPU Not likely, unless there is a major change to how it works. Pushing a wet noodle through a tight hole that curves is pretty difficult. What I think is more likely to happen there is since multi-material has really become consumer(or at least "prosumer") level, that we might start seeing some kind of TPU that is rigid until the first time it is melted. I don't know how the hell you are going to do that, but that's a problem for someone smarter than me. So on the arc of dumb things. I was looking for a Saturn 2 FEP tensioner block as I think my last one was too tight. Saw one that was a single piece instead of two, printed it, went to change the FEP, and realized it was for a Saturn 1 when it was smaller than the vat frame  Anyway, 2 piece printing now.

Can you actually meaningfully anneal prints in a sous vide cooker? I think about it every single time I see the title, but results seem inconclusive.

I accidentally very nearly melted an ASA part because I thought it was pc cf, does that count as annealing if I did it on a sous vide capable oven?

I picked up on major sale from 3D PrintLife PLA which is 'Dura' which is supposed to be 'Nylon Like'. Except, there are no analogs to how to print it. it claims to want 175-195c and a cold bed, but i have reprinted my Hydra AMS parts a few times in it since it keeps failing. 185, 45 bed, and low aux fan seem to be working so far, but i think I wont use this stuff again. Non 3d print related: My monitor arm with my 24" and 32" monitor held strong to the table, but the table broke off a huge chunk and it all fell to the floor. Rip 32" 1440 monitor, i hardly knew ye. At least I didnt pay a lot for it. But i need another, and a new table

Ok so how do you pour out the Mercury X/S wash station containers without getting resin contaminated IPA everywhere? Edit: Man, I made the mistake of letting this sit for a few months after my last print and so much crap has precipitated out. This is going to be a bitch to clean. Don't be me, clean your first wash IPA before leaving it. DP: I just poured quick into a large flat container, and then from there into some bottles for cleaning.

The airfoil is getting there. Just waiting for the tensioning wire to arrive. The next one might a bigger one printed in the foaming PLA Aero with some carbon fibre on top. Anyone here who has used that?

It is a (lower) rear wing for an older Alfa race car. The rules limit size and placement of wings. Thus it needs a varying angle-of-attack to work as a wing and needs the right dimensions that car and installation. The present shape is based on E423-II profile and whole car CFD simulations. Once it is installed we need to put some flow vis paint on it to see how those match with reality.

I can hear the fans and chamber fan, but I barely hear it printing. I actually was printing yesterday and watching a movie and I had to check on the printer a couple of times because I couldn't hear it. It does make noise, but not very much. Disclaimer: My only comparison is the Bambu before the noise cancelling and an Ender 3 with the 4.2.2 board, both of which are considered "loud" printers.

Doh, I just formatted the SD cards in all of my printers last night because of this. The earlier firmware revision changed the naming scheme of the timelapse files which apparently caused the confusion

Gonna vaguepost vent here: I was watching an old scifi show and got the urge to 3d print a prop from it. Looked around and found a well-detailed STL already existing, except it was behind a patreon paywall. Fair enough, subscribe to the patreon to get the model, only to find out that the person has set it up so you can only see old models after subscribing for three months. And, no, there isn't a way to just pay three months of patreon subscriptions at once to get immediate access. I guess it's some thing where the long-time subscribers to the patreon were salty about paying for years to keep access and didn't want upstarts getting immediate access. If the dude just sold individual STLs on a website, I'd be more than happy to pay for the single model and be on my way. Instead I have to wait multiple months, and then I'll probably download four or five models and move on with my life. Seems like a lose-lose situation for both of us. I dunno, maybe there's some copyright reason why they can't sell STLs directly. Grumble.
