The 3D Printing Thread

Anytime I talk to my mother about anything:

"Well aren't you just a font of useless knowledge."

I’m slightly autistic probably and just absorb knowledge any time there are numbers involved. lol.
 
The theme of our Christmas party was just announced as being "space". Not till January but I've already got the gaudiest cosplay ideas in my head.

do any of ya'll have a 3d printer that can do ABS or PLA? there's a non-critical part on my car that is $700 to replace and not covered by warranty, but there are 3d printer files for it.

PLA is super common but probably not the right material you would want to use for a car part. ABS would be much better. I don't have ABS material but my printer can print it.

would it cost me less than $700 to buy ABS material to ship to you and ask you nicely to print it for me? *bats eyelashes*

I wouldn't print in PLA for something that's going to be in a vehicle. PETG or ABS is what you're going to want.

PLA's glass transition point is 60C/140F so it would warp on a hot day in a closed car. PETG is 85C/180F. ABS is even higher but my janky baby 3D printer can't print it, lol.

If you want someone to print it professionally the podcasts I listen to (oh god yes I listen to additive printing podcasts) always talk about PCBWay as a website that will print items perfectly for you. I think you can upload the STL file directly to them and pick a material. www.pcbway.com

EDIT:

Try here.

i know literally nothing about 3d printing, but here is a link to the thread about the part i need, specifically driver's side lower, aka Lower Right.
Oh it's from a 3D scan?

That's neat.

I can give it a shot in PETG but it's going to need post-processing (sanding/painting) as PETG will come off the printer with a "shiny" black finish. I have matte filaments but they're all PLA and I wouldn't trust it not to melt right off your car one day in the sun, lol.

See the website I linked above for PA6-CF/Nylon or ABS/ASA printing which would probably be able to go right on the car (that piece was likely originally made from one of those plastics).

Hope that helps!

EDIT: hehe since I had the file.

$10 is a less than $700
 
This is so incredibly stupid and large that I just HAVE to do it

I even was able to log into this dude's TinkerCAD account and get a light up star for the top too.

0.6mm nozzle with 0.36mm layer height is gonna take about 3 hours per piece from the looks of it. It BIG.

Makes we want to get a 0.6mm nozzle.

I use mine for anything that isn't artistic.

With PETG it has a great advantage of also making the parts stronger too.

I actually just picked up some Rapid PETG which I've never used for the actual "leaf" parts so hopefully I can print those faster than that dude printed them on an Ender 3 (which is 2-3x slower than a Bambu A1 in just "regular" mode IIRC).

Here’s the base piece for scale rcubed (we have the same size build plate)

Since the A1 mini is on sale for $200, I'm debating about adding that to my options. I'd get a 0.6mm nozzle or two while at it.

With the possibility of additional tariffs from Chinese goods it might be a good idea for these lower end printers. They're never going to be any cheaper than right now imho.

That said we do a lot of additive printing in this country and all the machinery is made in China right now. If he puts it too high it will end up hurting the auto industry and their big $1,000,000+ HP & Stratasys SLS printers.

Some of the parts on this are janky AF and are going to require me to remodel.

So uh... maybe Christmas next year? lol.

I need a lot of gumption to get this shit done because it's about 12 different models the literal way parts are attached to each other is too thin in the model (those circular bits on the end are connected by like 0.01mm of plastic and keep falling off). I tried printing as slow as humanly possible and they adhere but fall off when connected. Ugh. lol.

Oh and hey rcubed tons of new features were just added to Bambu Studio including updated retraction settings for official Bambu filament and what looks suspiciously like features that would work better for a larger printer than they currently make. I was surprised last night by how much they actually streamlined old things and added new features. This should all port back to Prusa Slicer eventually as well.

21% purge savings is fantastic.
