3D Printing

arkcom, in Project Farm's 3D printed ratchet video highlights some not-so-obvious problems

The rachet didn't fail at the layer lines, the gears stripped. It could be a slight under-extrusion or designed with a lot of clearance to make sure it will actually be able to move after print.

Rolldach, in Is the bambu P1P really all it's cracked up to be?

I can’t talk about the p1p as I have the x1 (I have one at work and one in our hobby space) the both have done about 50h so not a crazy amount of time. Up until now it’s: slice the file and print it flawlessly with not adjusting of anything with perfect results. And the amazing thing is, the (near) perfect print comes out about 3 times faster then any printer we have in much better quality (we have an ultimaker 2, ultimaker original and one I forgot the name of). The only negative thing I have noticed is, that sometimes the seam is more visible then in other printers. Here a link to a pic. I have never had it that bad: https://forum.bambulab.com/t/how-to-prevent-seam-bulging-out/3891

Harry,

We are testing an x1 carbon right now, too. It isnoretty amazing .

rbusterbuster,

Rad, thanks for the insight. From everything I have read so far, the x1 and p1p aren't too different, so should be a decent comparison. I'm mostly trying to do cool looking pots and little toys for my kiddo, so don't need perfect prints. Just need it to be able to print more than twice without having to tinker with it. I have wasted a lot just doing test prints.

Rolldach,

You really can just print without tinkering. I would recommend to buy the textured PEI plate as well. It’s really an awesome printer!

rbusterbuster,

Fantastic, thanks for the recommendation man!

keeb420,

Man I'm really trying to not spend money and you're making that hard. I have an ender 5 pro and even if the print speeds were the same the p1p would speed up printing exponentially just from the everything else associated with it.

Boinkage, in Generative AI-powered CAD software aims to bring functional 3D printing to the masses

Just waiting for a stable diffusion version where I can type in “classic fantasy dwarves in the style of games workshop” and run that straight to my resin printer.

I have my 3V2 to the point of being "just print a thing"-ready but it's taken a lot of learning and tinkering, a lot more than you've done. I'm glad I did it but if I were in your shoes yeah I think I'd put that on the backburner until the kid's a little older and not quite the complete time-sponge.

Once they're older it might make a great educational and fun thing to do with your kid, too.

rbusterbuster,

For sure, I vastly underestimated the amount of time I would need to put into it. I have some nephews that are coming of tinkering age so I do wanna keep it around and keep learning. Overall I think it's a rad hobby, so when I have time for hobbies it'll be good.

CobraA1, in What 3d modeling software do you recommend in the year 2023?

I like to own my own stuff and run my software locally, so the cloud stuff isn't really all that appealing to me.

I'd like to try Fusion 360, but I'm primarily on Linux, and they don't offer a Linux client and for some reason it doesn't seem to work in Wine.

FreeCAD is okay, but I keep running into the topological naming bug, which is frustrating to work around. CAD Sketcher is nice, but doesn't have a lot of features found in other CAD packages.

Recently been into OpenSCAD, I have software development experience and some Computer Science background, so it's been really nice for me to work with. My biggest problem so far has been performance when telling it to "render" more complex models.

OlderNotWiser, in What 3d modeling software do you recommend in the year 2023?

I like the community edition of Solid Edge (2023 version). The conversion to .stl seems very solid, and is done locally (not sent to a server somewhere). The only minor negative is that I have to do my versioning manually. The Siemens/Mentor documentation is OK, but there are lots of tutorial on the internet.
I started my 3D printing hobby with Autodesk Fusion, then tried FreeCAD, and have finally decided on Solid Edge -- the UI was easier for me to understand than FreeCADs, and the conversion to STL is done locally. All of these are much easier to use than the microwave/RF physical design programs I had been using at work, so I may have a higher tolerance for UIs than some :-)

Freecad for most of my work. It took an adjustment period coming from Fusion but the community is great and the development is going at a good clip. Autodesk continuously changing their hobby model and if you cnc they gimped us hard on toolpathing so we need healthy alternate communities that are open.

IanBradbury, in What 3d modeling software do you recommend in the year 2023?

I'm currently using OnShape (free edition) and to be honest, I love it. On the rare occasions where I have no clue how achieve something it's very easy to find too many videos showing the how.

I would like give Fusion 360 a "proper" try but each time I load it up and then look at the limitations, I just get put off.

I'm not sure that even if I had the money I'd pay for OnShape. AutoDesk have great products but I find it very difficult to like them and their view of hobbyists.

waraukaeru,

I've mostly switched from Fusion to Onshape. Fusion does have features Onshape doesn't have, but most of them are beyond the needs of someome designing models for 3D printing.

Onshape seems to respect their users, and Autodesk treats you like shit. Fusion has all sorts of logic errors that cause it to perform terribly or crash. And it still has all sorts of weird DPI display issues.

So, I corroborate your impressions. I don't think you have to give Fusion a fair shake, your impression is spot-on.

I recommend OpenSCAD for people like me. It's parametric, open source, text based, code based, no cloud, no subscription, no corporate bullshit. I've got thousands of .scad files, some over 10 years old, and I can open them all.

I've used OpenSCAD for a fair number of things. The issue I have with it is importing airfoils is... not easy. but it being scripted is nice- the files are small, it runs light, and you can program a lot of if-thens to abort compiling if the parameters go too far out of whack.

I want to learn freecad again now that they're adding simulation to it.

Definitely fusion. I had no trouble learning fusion with no tutorials for the basics. ie draw, extrude etc. I loaded up freeCad yesterday and had no idea what to do. this is my current little project designed in fusion.

EchoVerse,

I really liked fusion360 the only problem is they keep changing licensing. All of my experience is as a hobbyist so it really is a pain when they cripple my cnc or limit the number of projects. Who knows they might start charging for colors or something crazy like Adobe.

I wish i would have started with onshape or freecad. Also I think solidworks is extremely discounted for EAA members

waraukaeru,

Onshape is really not hard to pick up coming from Fusion 360

Inamin,

totally agree. I do my hobby work under a work funded fusion account. If I didn't have paid fusion, I'd probably persevere with freecad or use onshape. I liked using onshape - it's pretty similar to fusion from my experience. I haven't tried tinkercad yet. TBF the charging for colours was a pantone thing. What shits me with fusion is if you want to render an animation you still have to pay for it to be rendered in the cloud even with a paid subscription. use case is pretty limited but it would be a nice thing to play around with, especially given most home computers are more than powerful enough to render at home.

I've used Onshape a bit and it is nice. Free accounts files are posted publicly, but to me that isn't a huge deal.

RobotToaster, in Bambu Lab issues recall of A1 printers over heatbed cable
@RobotToaster@mander.xyz avatar

Isn’t this the second time they’ve had “house burning down” level bugs?

EmptyRadar,

There was an issue a while back which caused their cloud service to be inoperable for several days, which broke many features but the printer still printed. I could be wrong but I think this is the first serious hardware problem, at least which necessitated a recall. Someone please correct me though if I got that wrong.

RobotToaster,

IIRC they had an issue a while ago where their printers were just randomly turning on and printing because of some cloud bug, that was the first one I was referring to.

You're right - I remember that now. That was before I got my X1 so I didn't experience that one directly.

VanillaGorilla, in Me an hour ago: I hope this ASA print sticks to the bed. Me now: how do I get the purge lines off the bed?

On top I got errors posting this, so I ended up deleting five copies I sent accidentally ¯\_(ツ)_/¯

Plavatos, in Curious case of the nozzle leaving the extruder

Am I understanding that you found the nozzle IN the print itself? Like it unthreaded and left the heat block?

Have you tried threading another nozzle into the heat block just to see if there are still threads left?

fsniper,

Yes exactly this is.

After this I used a 0.8 nozzle. And could print with it. So threads are still there.

I suppose I mistakenly didn't fully screwed the 1.0 nozzle. With the large layer width Pla stuck on the nozzle, as the print was a rectangular shape on each turn that pla applied some tork and nozzle unscrewed.

Plavatos,

That is pretty crazy, definitely a new one on me but I think you’re right how it happened. I’ve seen a video where someone used a torque wrench to set the nozzle just right but I can’t bother with all that…
