3DPrinting

I left the print over the weekend and I came back to spaghetti. It looks like something, caused the printer to push the print off its base like it was a poorly leveled bed?

I still have to watch the camera footage to see what failed, but I hope you guys get a chuckle out of the spaghetti monster like I did.

Hi, I've tried to print a model plane for my father. It's this model, using this LW-PLA right after purchase.

As you can see in the image of this post, the print is going well until it reaches a certain layer, where the filament does not get deposited properly for the entire layer, only intermittently. The following layers then, of course, have the same problem and I get this failed print with these "frayed ends". Additional attempts failed the same way at a similar layer count.

If someone has some experience with lightweight PLA (LW-PLA) and knows what can be done to solve this, I and my father would greatly appreciate the help.

Thanks in advance.

Edit: Additional info: I'm using the PrusaSlicer files from the linked page. Edit2: The printer is Prusa Mk4.

I have been trying for many hours now to print this circular model, but have been running into inconsistent extrusion and stringing. just before printing this, I successfully printed a set of Hextraction tiles, so I'm not really sure what the issue is. I also printed this model successfully in the past with the same settings.

I am using a Sovol SV06 with stock firmware, and PLA with the hotend at 195° C.

I also did a full calibration to see if that would fix the issue, and it did not.

So I was attempting to install kevinakasam's belt mod and I'm fairly sure I stripped the thread that holds the M4 screw in the outer right side of the X axis profile (the side without the extruder attached to the tensioner). How screwed am I? Could I get away with trying Loctite red?

Pics for reference!

Edit: Thanks a ton everyone, I'll keep you all up to date when I try to finish the project this weekend!

I've been playing some gyroscope based racing games on my phone and thought it would be cool to have a physical steering wheel to hold.

Since I already have a magsafe ring stuck to the back of my OnePlus Open I designed it to use magnets.

Functionally it makes the games way easier to play since you can really precisely tilt the phone. You can even steer one-handed pretty easily too

The magnets I used are a little weak so I'll be replacing that with another stronger magnet ring I have

I'm thinking about buying a 3D printer for creating cosplay props like helmets and armor pieces (only once I figure things out, I'll start small of course) among other things and since there is a sale on the Ender 3 V3 series and they seem to be well received I figured that it would make sense to buy one. Having done some research, it seems like the regular V3 with it's 220x220x250mm build volume is too small for what I'm planning to do. Though splitting some parts will of course still be required, from what I could gather the V3 Plus better matches the recommended build volume having one of 300x300x330mm. The sale puts it at about the original price of the regular V3 which works for my budget.

I'd love to hear some thoughts on this, since my knowledge is limited as well as theoretical and the quality of internet sources varies quite heavily.

Edit: Thanks to everyone for the help! Just an update.

Thanks to @nate3d and @IMALlama comments below I calibrated the e-steps that were very under and it improved a lot.

I left the filament on the dryer for 8 hours and tested again with a 20mm /s speed and 220 C print temp and it was better (picture below)

Just to answer you all saying it's a clog or a hot end problem, it's not, the whole hot end, includong nozzle, heat block and everything else, even the PTFE tube are all brand new and I checked before.

This is still the best I could achieve and It took 3 hours to print this benchy lol

‐-------- Hi everyone, I'm once again asking for your help lol Since I’ve tried to print with wood I totally wrecked my printer so I changed the hot end and am trying to set it all up again. Since my printer already came built and working I don’t have much experience with things like this so if you could help me I would be very thankful

What do I need to twerk to make it print better again?

I’m using Cura slicer and trying to print a benchy with the settings below:

Nozzle: 0.4

Layer: 0.2

Printing temp: 220 (it wont print with lower temp)

Speed: 60

Retraction distance: 7

Retraction speed: 70

Edit: PLA

Was having clogging issues so I thought I'd replace and get the mythically good capricorn tubes. This is a good sign that I needed to.

I need to print a discontinued part for my car, I have an .stl file for the part, I just don't have a 3D printer. It's a speaker mount.

What online print service have you used that you can recommend? Thank you!

Edit: located in the US.

I've been considering getting refills to reduce my plastic consumption, which means I would have to print master spools with PLA or PETG.

Because I don't consume my filament quickly enough, I got the Sunlu S2 filament dryer, which heats up the filament to 50-60C.

My question is: would it be OK to put a master spool in the dryer, or could it potentially deform?

I'm printing with PLA on a "PEO" print bed (really a textured PEI), on my heavily modified ender 3, and there's a pattern on the bottom of my first layer that I'm trying to get rid of. The top of the first layer looks fine, and changing the z offset in either direction doesn't help. I've also tried slowing down the print speed because I thought the extruder might be skipping, but I'm still seeing it at 10mm/s. Any idea what could be causing it, and how to get rid of it?

Edit: the first layer went down from the bottom left to the top right, but the pattern I'm seeing is perpendicular to the extruder path

If a 0.4mm nozzle is 4x the area of a 0.2mm nozzle, should I print 4x faster with a 0.2mm nozzle?

Context - I think I'm having heat creep and printing too slow. (ender 3, pla 210c)

I foudn this program https://www.thearmoredgarage.com/ and just wondering if anyone has any experience with it and if it's worth buying or not?

Copying this from reddit. I am not OP.

Hello All! If you are planning on coming to 3DPrintopia in Bel Air, MD on September 28th and 29th this year, please consider printing, signing, and bringing along a blue tile for the "Layer Connections" Community Art Project. Spearheaded by stlDenise3D and 3DPrintBunny, the project has already collected roses at the Midwest RepRap Festival (MRRF) and the Rocky Mountain RepRap Festival (RMRRF). It'll be making a final stop at the Sanjay Memorial RepRap Festival (SMRRF) at the end of the year.

More details on the project and links to the STL files can be found here. The main stipulation is your tile be a shade of blue. Come 3D Print with us! A Community 3D Printed Art Project ⋆ stlDenise3D https://stldenise3d.com/come-3d-print-with-us-community-3d-printed-art-project/

This is the temp tower of my wood print experiment Cand even se much difference. It goes from 260 to 190. Below 225 gets really flimsy and above 240 melts. But even 230, the "best" one is really bad, and I'm not talking about retraction. Even the layers that melt are inconsistent.

Also it's not humidity since the filament was in a filament dryer for.16hours.

edit: The nozzle is 0.8

can someone think of anything else?

I have an indoor/outdoor thermometer to keep track of how hot the back of my Expedition gets. I drive pretty regularly with two dogs in the back, and over the summer and winter the temps can get a little extreme.

I need to be able to take it out to keep an eye on it remotely (it has about 1/4 mile range) but also have it not rolling around while I drive.

There was a coin holder there that I popped out, and used as a template for an insert to keep this mounted semi-permanently.

Printed with kinda crappy Amazon Basics PETG. If it holds up well, I'll reprint it with better quality black PETG so it matches the car better.

I was experimenting with bottom patterns in Orca and octagon spiral looked cool. I tried it with RGB filament and it came out amazing!

There is a depth to it and it changes with the angle

I haven't seen this before online so figured I'd share!

I want to mount a printed part to a standard 2mm motor axis which doesn't have any dents or profile. Its just round. If I print at exactly 2mm, it fits for the first few times until it gets too lose and the spinning part sometimes falls off.

Is there software that will automatically cut large STLs based on the printer you have or is cutting something you just have to do manually?

TL;DR No.

What you should do:

• buy fresh IPA. It is approx. $5/L. As such a 2L washing bin is approx. $10 + 10L waste disposal. In the broader picture of total costs and production value, this is manageable (resin cost, machine depreciation, PPE/gloves, ...)!
• use two or three stages of washing
• fill the washing containers with as little as necessary to get it done
• periodically expose the liquid to sunlight and let the particles settle down. Separate the "clean" liquid from the sump (you might add special chemicals to speed up this process).
• if the first stage needs replacement: 1.) responsible disposal of the liquid in compliance with local regulation 2.) move the liquids around: (the third stage is the new fresh liquid, the second is the prior third stage and the second washing station is now the first "dirty" stage).
• check for alternative chemicals that can be used with your particular resin

If you use water-washable resin: IT IS A DANGEROUS LIQUID! Dispose of dirty water responsibly as chemical waste.

Long answer:

To answer that, let's first look at what isopropanol (IPA) is: Its formal name is propan-2-ol and its CAS number is 67-63-0.

As a starting point, check a database like GESTIS (German) and NOT wikipedia: https://gestis.dguv.de/data?name=011190

At the top of the page we see that it has GHS-02 and GHS-07 warning labels. Looking further, it is a colourless liquid with a flash point of 12°C and an ignition point of 425°C. The explosive range is 2-13.4% vol. The signal word is DANGER.

Scrolling down:

The substance forms explosive peroxides.

What does this mean?

There is no mechanism mentioned, but generally, if you expose these chemicals to sunlight they will react over time to form a peroxide, which is much more reactive and can explode at high concentrations (there are exceptions to this rule, but most of them go boom).

This means for distillation:

• avoid "old" IPA if possible
• check for peroxides (if necessary, treat the peroxides before distillation)
• don't distill dry (leave some liquid in the sump to avoid high concentrations of peroxides)

As I believe this shouldn't be done at home I won't tell you how it can be safely done (if this isn't enough to deter you: read scientific literature/books describing how it shall be done).

Instead, focus further on what advice is out there on the internet/YouTube:

• A water distiller is made for water and water isn't flammable and doesn't form explosive atmospheres. In other words they are unsafe for Isopropanol or Ethanol.
• Do you think a 2kg fire extinguisher is enough? Are you truly capable of thinking rationally when there is a fire or would you panic like most people?
• Don't even consider doing it indoors or in a garage.
• Don't work with large volumes. In a laboratory with proper fumehoods and equipment, there might be limits like 500mL batch sizes.
• If somebody isn't wearing eye protection or heating large amounts of liquid without stirring question his qualification to talk about this topic. Being an influencer or posting online, like this post, doesn't require any formal qualification as such even the big YouTubers/influencers post horrendous content that is dangerous or misleading.
