does anyone wearing a wireless headset around the 3d printer while printing ??
i noticed a crackling sound when near the printer/psu ( cr10v2 ) during the print
and a massive surge when powering off ( in the moment the power gets cut off ) where my wireless headset seems to be jammed or something for 1,5-2s
i was wondering if this is just a cr thing and/or if other anons have noticed it as well (preferably with the cr psu)

Don't disregard vapor smoothing too quickly.
In my experience, fog disappeared in a day or a couple of days (I don't remember how long it took. Acetone takes more time to escape from ABS than getting in. )
Although my samples weren't completely clear, and are still a bit milky, I was assuming it was due to water moister in filament and not-tuned settings. But I did not try to polish it by hand, so I cannot compare it.

I have absolutely no data to back this up, but what I imagine some inconsistent clogs being like is if you take a business card and put the corners between your thumb and forefinger; imagine the semicircle created is representative of half the nozzle. You can spin the card around and it will either block more or less area depending on its angle, which blocks flow.

Go for it. Disregard patents and make it for yourself (If you have time and money).
If it works and it has benefits compared to other SLS machines, then printed parts will also have some benefits, which means you can sell them (if they are better, or cheaper, or bigger,,...). And you can provide it as a service with a handful of homemade printers.

For any kind of mass production of 3d printers, you are gonna need to redesign a machine anyway to be fit for mass production, safety standards, serviceability, costumer support.... This kind of needs a bigger investment. And this is why many kickstarter printer failed. They might had a working prototype, but design was not fit for mass production and they did not consider all the problems with mass production.

you need sub mm resolution for microfluids, labchip has many papers mentioning the Ilios Ray (2 micron) but sub mm tubes need something that can reach a really high resolution, usually by focusing down a projection. a form 3 can reach "sub mm" xy resolution but a guy with shrinky-dinks and a cnc lathe can reach a smaller resolution than them.

For use with the Photon, you mean? Yeah, it's loads better than the default crap it comes with. Prusaslicer's autogenerated supports generally are very good, but I still manually orient my models at the least (since I know what sides I want to look *good*, and the auto-orienter only considers the best orientation to *print*). It's always worth double-checking if there's any un/undersupported areas, though, no matter what generator you use.

Why? I mean there's good reasons, but you probably can't even name the - it's usually just a matter of personal preference rather than actual, honest to god practical performance benefits. For most 300^3 mm^3 printers, V-slots and wheels are fine - if they aren't, you ought to look into production methods other than FDM.

>Do I have any other options?
Buy a Chiron and some linear rails, and start bolting them on axis by axis.

>> No.1768653

>>1768614
I don't trust the precision of the extruded profiles. They are extruded. Not machined or ground. There is no specification of tolerances. Similar thing for plastic wheels.
Moving y axis: if it is sturdy: it is heavy, if it is light, it's not sturdy. And if it is heavy, you have problems with ghosting or you have to print slowly.
All those problems are more pronounced for bigger sizes. I was also looking at 400^3 mm and 500^3mm.
If there is nothing else, I ma gonna go with one of these, but I am looking for something else if possible.

Adding linear rails is also an option I guess

>> No.1768671

>>1768653
Have you ever owned a 3D-printer previously? The acceptable tolerance for most people is roughly 0.1mm on a 20mm cube, and that's pretty good considering shrinkage and filament inaccuracy. Sure, a good linear rail might be accurate up to 0.01, but who cares when your nozzle over- or underextrudes?
Moving Y-axis is in principle a bad design, I'll give you that. Makes zero sense from an engineering standpoint, it's best to go for an XY head and Z-bed. However, economy of scale still applies: might as well go with inferior kinematics if the quality is ''good enough''.
In my Chiron I have not found these problems to be more pronounced than on, say a Prusa, Anet or Ender. They are less pronounced than on an experimental Velleman (XY-bed, retarded setup for most people), I just run the thing slower than an Ultimaker (45 vs 60mm/s). To me, dialing in jerk and acceleration is more critical than maximum speed, and to compensate the lack of raw speed I just use a big nozzle and big layer heights: extrusion flow has more to do with those two than outright speed after all.

Your most economical option would be to buy a Chiron or CR-10, see if they're up to your snuff, and add chase accuracy only if necessary - and there's better ways to do so without linear guides. I'd be looking at extrusion, temperature control, and heated chambers, mainly, since shrinkage and such account for a proportional deviation that's present in every single case, rather than the absolute deviation given by wonky kinematics.

Removing supports for PLA sucks ass, IMO. ABS is much easier to carve into and break off. Either case, I get a pair of spring-loaded needle-nose pliers and try to grab the accordion looking bits and hope they pull other parts of the support. I use an exacto knife to shave the remainder off.

Bent bed, can be "fixed" with a glass. But bent or inaccurate extrusion? Replace it with another extrusion (which might also be bent?).
For small parts inaccuracy of alu-extrusion is not so visible, But I am afraid at 300mm (or even 400, 500mm) it will be. But I cannot test it atm, because I don't have that kind of printer yet. Also I plan to use 0.4mm nozzle and 0.2mm layer height, I cannot go much rougher than than that. Printing PLA.
As I said, I am looking for different options if possible.
If not, I am gonna buy what I can get.

Perimeters are the amount of lines that form the outside shell of your part (as opposed to the filling inside). If you need something to be high strength it's generally a good idea to first increase the amount of perimeters, because all the infill in the world won't do you any good if your outside layer is 0.4mm thick and you can punch through it with a fingernail. Higher infill is more useful on large, flat parts that would otherwise flex inward, but usually anything above 15-20% is not really needed.

You can try, but with an FDM printer the strength (and shape) of the joint will depend on the orientation of the print.

I remove them with pliers. The "line" support type, which just makes tall, loosely-connected 1-layer-thick walls is good for this.
Each wall only has a single line of contact with the print, so if you just grab it with a pair of pliers and pull, it tends to break off of the print cleanly, without leaving any remnants behind. You can even grab big chunks of support at once, assuming they're not attached to delicate parts of the print.

I'm having a bit of trouble with making detailed prints with ABS. Purple is ABS, orange is PLA, both are 0.1mm layer height, cooling fan was off for ABS. Why does the purple one look like crap? I went slow and made sure there were no drafts in the room and that it was reasonably warm, so there was no warping or peeling from the print bed, but it looks like it's just half-melted already.

You could use a printer but you need to consider that the print will have 'cleavage points' (if that's the right word) between each layer. So the orientation of the part is important. For that I would cut the 3d model in half across the circular face so that there are no cleavage points on that cylinder part. Otherwise it will likely break very easily.

Of course if you have the money and patience, then making a mold and using resin would be much better.

if you are getting started buy a cheap printer

since the nature of your question dictates that you are not buying the printer for engineering purposes i would suggest to save the 100 bucks and buy the ender 3
of course only if you dont need any specific features from the e5
also bear in mind that the devil hides in the detail for example 125° bed temp is most likely due to no glass plate if you look at the 110° that creality lists for the printers that come with a glass plate
should take everything with a grain of salt
and keep "reading" yourself more into the topic
i guess you are not particularuily doing anything wrong with buying the e5 but you definitely have to double check with your ambitions / requirements from your projects
it may be a better investment on the long term to buy a cr10 for example and to upgrade it

What slicing settings do you recommend for this print, guys? This is the midde section of a seven-segment display. The thickness of all the walls and foundation is 4mm (should I make it more? less?). The holes are where E10 lamp holders will go, 11mm each.
I don't care how much material it will take, I only want less time to build it (can't sleep while it's on unless haven't slept all previous night or on xanax) and to be reliable (not to collapse onto itsef or something).

>4mm shell thickness with 100% infill
>1.2mm layer height
1mm is plenty for wall thickness, your nozzle is 0.4, so go for 1.2mm shell thickness. 100% infill? Reduce that to 40-50% for a stiff part, or 20-25 for visual parts. Any increase in strength can be had with an increase in shell thickness - 4mm is overkill!
Set your layer height to 0.2mm, that's what's going to save you the most print time.
'"Super Quality'' implies a stock profile with a very low speed, probably 20-30mm/s. 40-45mm/s speed is the sweet spot for most untuned Ender 3's I've seen.
Go into advanced settings, that allows much more tuning - that way you can at least show us all your settings, instead of the EZ-mode setup. At least there you can adjust your printing speed.

If your Ender 3 has an uneven bed like almost all of them find the nicest spot and print from there.

Based on my Cura settings, it looks as though the fan is at 100% for every layer past 4, and the surface is at layer 25. The fan gradually increases to 100% from layers 1-4.
Would turning the initial fan speed to 100% so that it's running during the first few layers really make such a difference so much later in the print? Or is there some setting I'm not seeing that causes the fan to be off during certain later parts of the print?

you should learn to script in features for cura, there is a reason why prusaslicer kept the ability to run a gcode post processing script, if cura showed "type" as ironing layer you could prevent the ramping up and down of skin fan speed.
set another one on inner/outer walls for 100% to keep them on where fans are needed. dont keep this on for smaller prints, most cooling solutions don't need this script but some do due to weird things at full fan speed.
slic3r's scripting is nice if you want to compare the fan off/on for top layers.

It seems you were right, at least mostly. The scripting stuff you mentioned is gibberish to me right now, but I manually disabled the fan when it got to that layer, and the big rough area never showed up.
However, there is a smaller rough area that I now notice due to it being the only remaining imperfection. It was present on the previous full print as well.
While this imperfection is pretty close to an edge, I'm not certain that it's a leveling issue because the test print that I did before this one to test the fan theory, which was the same print sliced down to just the top handful of layers to save time, did not have the smaller rough patch. It was perfectly smooth.

If the cooling fan could cause such a problem, is it possible that a draft could as well? The only other uncontrolled factor is that I realized I had the ceiling fan running while printing.

No, I'm printing at the nozzle diameter.
Additionally, my top surfaces in general are fine. Even using these ironing settings, the three test prints I've done of various sizes so far have all had impeccable surfaces. Turning the cooling fan off fixed the large imperfection, so now all I'm left with is one medium-size rough patch on the surface of this specific part, whose surface is otherwise perfectly smooth thanks to the ironing.

Ok, here's my report on my stringing adventure.
1 is cura 185 [email protected] (temp retract [email protected] speed). Probably the second worst overall, very fine hair stringing.
2 is cura 210 - [email protected] This is the worst, with some oozing towards the top.
3 is cura 185 - [email protected] Dropping temps fixed the oozing, but stringing is still bad.
4 is creality slicer stock settings. 0 stringing until halfway up. At this point I find a video by makers muse, using a stringing test that's larger and has 0 stringing.
5 is that stringing test with creality slicer, 0 stringing, a perfect print.
6 is 185 [email protected] I notice retract speed is 80 in creality slicer, so I try that. Helps a reasonable bit, but still no dice.
7 is the magic setting, retracting at layer change too. 200 [email protected] Stringing fixed using cura.
Only thing now is the flat surface of 7 is much rougher than 5, and has some white lines. Anyone have any idea?

overall feels far more brittle than other prints ive handled, it was the cheapest filament i could find after all

Make sure your bed is clean as well as being level. Higher bed/nozzle temps can help with first layer adhesion. I'm using some black filament right now that is fussy about sticking when the first line goes down on the bed, so I do the first layer at 220C/70C.
>it was the cheapest filament i could find after all
How cheap? Even the cheapest ones I've seen on Amazon were only like $4-5/kg cheaper than the name brands like Hatchbox.

>A microfiber cloth and isopropyl is enough right?
I used to think so as well, but it turns out that nothing beats good old dish soap, water, and sponge for cleaning glass.
I still use isopropyl occasionally to get stray bits and whisps and such off, but if I need the bed truly clean I wash it with soap.
Although, I realize you haven't mentioned what sort of bed you have.
I'm not sure if the default Ender bed agrees with soap. I assume it would, but I don't know.

Well, I tried another print with my ceiling fan off as well as turning the cooling fan off for the ironing layer, and not only is the small rough patch still there, the big one has also returned in exactly the same spot it was originally. Although it's not nearly as coarse as it was before, could the fact that it's now back after the previous print was completely smooth in that area, mean that the smoothness was just a fluke and the cooling fan was in fact not the issue at all? Literally the only difference between the last print and this print was me turning my ceiling fan off.

I'll try the different line width next, but if the line width was the problem, wouldn't I see such defects on the top surfaces of all my ironed prints? I don't get why it'd be only this print, and in this area. I'd think warped bed if my bed wasn't glass.

Is it possible that my top layers aren't laying correctly across the infill and are creating a slightly uneven top surface? I've already got 4 top layers, but the lack of an infill is the only physical difference, besides height, between this print and the cut down test print I did of just its surface, which came out great.

Slice in half lengthwise, print laying flat.

Assuming you're going to stick it up your ass: don't, it's way too thin and layer orientation is wrong for the kind of load it'll receive.

Is that so? Interesting. I'm not noticing it in the walls, just the surface. I'm doing a larger print rn and I'll see how it goes. I now remember seeing it before when printing flat surfaces, but it wasn't on that top layer, so it got covered by another layer that seemed normal. Thank you for your insight.

It is pretty common on completely solid structure like yours, to properly print completely solid structures you've got to have everything set up absolutely right, with structures that have some sort of infill you have places for the extra material to go to, with solid ones the extra material can only go outwards

I will also just clarify so I'm clear, when I say "rough", I don't mean as in there are spots sticking up like pic related. It's still smooth, but running a finger along it's like it has a shit ton more friction. And also visually the "smoother" one is shinier than the other.

>> No.1771647

>>1771620
you should never print with 100% infill, don't go above 90%
but other than that the effectiveness of infill compared to surface layer per weight is a really difficult thing to calculate, pretty much the only way to be sure is to make case by case strength studies and comparing the different infill percentages and wall thicknesses, but that is not really too feasible, so a good rule of thumb is that the walls matter more than the infill.

>> No.1771652

So for decorative/cosplay prints you spray a coat of filler and sand etc to get it looking nice.
How does that hold up to wear and tear?

I'm gonna be printing something similar to a wrist rest so itll have a fair bit of friction against skin.
Will it do okay if I were to post process it or should I avoid fillers etc?

The parts where the bed is lower just won't squish as much (or it will straight-up fall in extreme circumstances) and the parts where it is higher it will squish more. Over a few layers this evens out since the printer is always extruding from the same even plane.
