What are you making ⚒️ / 3D printing 🖨

:raising_hand_man:t2:

What printer are you using? By the sound of it, I assume a Prusa but I want to make sure.

My advice is to print on a really hot bed, like 105~110C or so, print a temperature tower with a slow flow rate and abuse it to check the layer adhesion, and then run a maximum flow rate test at the highest temperature at which the material behaves well.With a bit of care, it’s even possible to print ABS on an open printer.

ABS and ASA will warp if you print them with a flow rate that’s too high because some plastic will not have enough time to melt and this will create stress as the filament goes out of the nozzle.

A PEI bed and high flow nozzle or hotend go a long way to reduce warping and improve layer adhesion with these picky materials.

The other thing that you have to consider is thermal expansion as it’s more noticeable than on other materials. Orca Slicer allows you to set this for every filament profile and I think that Cura also lets you do this. But you can always scale your parts slightly when using other slicers.

Got a Q1 pro, it prints abs better than pla, and eat tpu for breakfast :sweat_smile:

I’m going through all the stuff I bought for the the ender 3 and had a rough time printing and it all come out perfect (except I kinda miss my glass bed, the PEI isnt as consistent, or I don’t know how to use it yet :sweat_smile:)

Also looking at pctg and nylon, but ASA seams a bit more stable and resilient (print and use wise)?

Just finished re re re re repairing. I did use the capricorn tubing, and when I put the original aluminum pushlock fitting back on, I quit having problems loading filament into the hot end.

In 23hrs and 47min, I might even have something worth showing.

Abs asa (pc?) and most of those material from there up that have higher than petg melt temps your going to want to pay attention to ambient temps, since you can get expansion and contraction in the middle of your print causing dramatic splitting and cracking

Probably wanna look into one of those pop up enclosures to keep things warm and bunch of those filaments start having definite vocs and odor, people have been know to just put a standard cardboard box of shame over their print when running and getting decent results, so you got options from low to high effort depending on what you wanna do

The tricky part is just because you have an enclosure doesn’t mean it will stay warm, if there’s too much volume and too little insulation, it won’t heat up enough inside… something something thermal dynamics or something

Depending how how you get your ambient temps to, supposedly the boards and control screens don’t like that long term, so many will get wire extensions and move them outside the enclosure

Cooling fans can be the devil,
As a super rough rule, the hotter the material, the more it will freak out from cooling fans… but you need some cooling sometimes for overhangs and such, so that will be a balancing act, but the least you can get away with is USUALLY better

The Q1 has a heated enclosure (one of the main reasons I got it) so that’s not gonna be an issue. On a hot day, even with the top lid removed and the door open, it gets a bit too hot for PLA :sweat_smile:

I’m more wondering on the strengths and functionality of the part once printed. PETG was ok, but I had better results with some PLA+ on the ender, I’m just wanting to step it up so I don’t have to worry if the parts stays in the sun or a hot car all day … Thi gs like GoPro brackets takes a beating, Id like to have them hold up more than the 20-30 minutes the PLA ones do :rofl:

Oh I thought someone with an ender was doing Asa, I can’t keep who’s who straight in this thread :face_with_spiral_eyes:

That was open Mendel type printer advice :man_shrugging:t2:

I was just thinking yesterday we need to start every post in here with make, model, and condition.

But I just know some joker amongst us will drop a 3d printer list to make my tongue hang out. :crazy_face:

I thought asa was very strong when I first printed a bracket for my old dyze dd extruder/hot end. Gave a good test flexing and bending it and was surprised how far it could bend and return back to normal shape with no damage

That would be me, I print ASA on my open Ender 3 with speed settings of 200mm/s and 5000mm/s^2. However, the maximum volumetric flow rate caps the maximum speed.

And yes, ASA is addictive. :stuck_out_tongue_winking_eye:

Let’s avoid turning this into 3D printing discord. I’ve had enough of that particular community and all it’s weird myths.

thanks for the feedback, I think I’ll get a roll and give it a go :grin:

I have a roll I’ve picked up for a project for a first responder I know who asked me if I could whip up a radio mount, but he’s even more adhd than me, so I’ve all but given up try to get my hands on the damn thing lol

In other news, I think I have my external power unit together… wiring didn’t go perfect, singed one connection but w/e… this is a proof of concept anyway… and I have a feeling the engineers won’t WANT pursue it… but they also can’t SAY they are willing to allow the amount of scrap and man hours this would solve

I’ll be curious what excuses they have when presented with a functional solution :wink:

2 switch’s so they can’t say they prefer one way or another,
Red connector block is glued in place, hot glue is just strain relief and a little bit extra… it’s messier than I wanted and not as even coverage… but w/e
Small dip in the bottom is for a dollop of hot glue to hold battery in place

Last picture
It’s always fascinating and annoying AF how a print can simultaneously be clean, and look aweful in certain light angles

I think I’m mildly pleased with this

I just need to find a way to word my proposal, that I want this unit back as an example of my design ability if I ever try to pursue something… lol

Last tool I made for them, was something like a safety can opener for new battery packaging that is an utter pain… they were initially just giving operators an exacto and saying good luck… :roll_eyes:

I love that when I put in my proposal for that tool they were like:
“Well, we don’t know if it’s safe since it uses blades”
Erie: “yep, I designed it to used the exact same exacto blades you were supplying to operators before, except this is shielded so they shouldn’t be able cut themselves without significant effort…
…ask the 3 operators that cut themselves last week if this is safer”

Them: gives extremely slightly redesigned tool, so they can try to save face
Also them: *gives written instructions to use this tool blade side pushing and twisting directly against their opposing hand… instead of you know… on a work surface

I have the same engineers, except mine can’t write a procedure, I have to do it for them :rofl:

It looks super clean, I love how 3d printer can solve real life problem and your project is a perfect example. Thanks for sharing the process and result.

TFW you realize that you’re the only real engineer at the company regardless of degrees…

Gawd. Don’t get me started on that

When I put in my battery cutter proposal, like 3 engineers were tripping over themselves to sing praise of how good a tool it was

…then they suggested I should try to transfer to engineering and if I had a degree, and I told them I have no piece of paper

Followed by a 3-4 weeks of them being butt hurt and redesigning my tool ( that took me an hour and a Half?) to put a larger handle on it lol

That’s exactly why i returned to school and started to work on my EE a few years back … i was training the new engineer to turn around and ask them to sign off on my design with their name on the paperwork … Since i stopped spoon-feeding them, people keep asking when i graduate so i can start designing systems again :sweat_smile:

I’ve considered it, but the prospect of new student loans… and I was never a great student
Great at learning, bad at school

Plus seeing some of the bureaucratic nightmare, I have my doubts

Homework becomes more of an abstract concept than a tangible object the instant it’s assigned
