I've been on a mission to use 3D printing to upgrade to fix and to repair as many of my tools as possible, and when it comes to tool repair, 3D printing isn't always what comes to mind first. If we want something stiff, that's precise it's better to machine it from metal and pay what it takes. But maybe it's possible to replace parts with the right filament, every day there are new and unique filaments coming out that push the boundaries of what we can do with 3D printing.
Having recently tested the QIDI Q1 and having good success with it, I went back to their website and I found that they sell a filament called ABSGF25 and it's not like anything I've seen before, so I contacted QIDI to see if they'd send me a spool to test out... I didn't specify the color, so they sent green, and that's perfectly fine, it showed up really well on camera.
All of the prints in this video were made on the QIDI Q1 Pro, it's still printing very well it's at least on-par with the X1C for print quality, though it doesn't have a color option at the moment.

Nice! Do you have an idea as to why they were printed this way? Maybe you can care to share why you think it's a good idea to print all of the materials with the same settings since you are an all-seeing and all knowing god-like creature.

Dude everyone is at different stages of learning. Knowing something another person doesnt, doesnt give you the right to insult them. Science requires us to share info with each other so we can see things and know things we couldn't otherwise as an individual. Thinking in such a negative way doesnt help anyone grow, nor does it foster an environment that promotes learning. If you know something helpful just share it. You are also most likely wrong anyways, because if it was in a heated enclosure the threads would droop before cooling. Maximizing cooling is the play here, since the colder the outer perimeter of plastic material is the faster it will cool the threads and the more accurate the threads will be.

My two cents: Glass granules will grind the rod. Glass is harder than steel. Wear on rod happens. How quickly and to what extent, I have no idea.

@dr_traktor Месяц назад

Not necessarily. It’s important that he pointed out that the glass is inside the core of the filament, not uniformly mixed into it. There’s a recent cnckitchen video where he shows with cross-section microscope images that the core of the filament remains in the core of the extrusion after printing. So it’s quite possible that the glass mixed core will remain entombed in an abs sheath and not come in direct contact with the lead screw.

@sierraecho884 Месяц назад

Very good point you are right I think.

@sierraecho884 Месяц назад

@@dr_traktor The outside laxer of plastic will grind down fairly fast in a use case like that and thus he glass fibers will lay open. Generally speaking you are right, filament flow in laminar out of the nozzle but the part later on will experience stresses.

@MikeKasprzak Месяц назад

I'd also be concerned that too small of a nozzle size would expose more of the glass core due to the stiffer (presumably less viscous) material. That said I could see cored filaments worked as long as a large enough nozzle was used, but I'd expect 1.75mm to 0.4mm to be too much of a drop, unless we knew the core was 0.2mm.

those pieces are made of bronze for a reason: to avoid damaging the thread. which is expensive to replace. never use glass nor CF in contact to a surface that you want to preserve. I would just do a simple bronze casting. Also you already have the machine to make it even from a lump of bronze, which could be a bit hard because of the wear, but not imposible. if you want more precision, make a tap to make it match. if you want even more precision, make a interference-adjustable nut to eliminate backlash. 3d print would work for a short duration, and you want that. you could bore the right screw out of bronze using the temporal 3d print as a temporal replacement. dont destroy the machine using glass, please.

@conorstewart2214 Месяц назад

You could likely design the parts better so that you don’t need as high stiffness. The original parts are designed to be made of metal and likely to be easy to manufacture. You might be able to better design it so that lower stiffness filaments can be used and that would then allow you to experiment with lubricating filaments like IGUS makes or PC-PTFE or PETG-PTFE, which contains solid lubricant in the filament and makes the parts self lubricating and have low coefficients or friction.

@axelSixtySix Месяц назад

Hmmm. Glass fibers are abrasive bronze is auto lubricating. So you may se some wear coming very quickly with a glass reinforced nut. And keep in mind plastic will never be as stiff as metal whatever you do, especially ABS. So your nut will act like kinda spring under load anyways. You should compare plastic materials to brass and steel to make up your mind. There's feelings and there's materials physics which should be your reference. Personal testing are feelings. The best filament for the job should be IGUS Iglidur, but I guess it's still too flexible for metal lathe applications. I would use a lost PLA brass casting or a SLS 3d print instead. Currently your lathe quality is far to be as good as it should be.

@conorstewart2214 Месяц назад

It is also possible to get PTFE blended filaments as an alternative to the IGUS ones. Spectrum make PC-PTFE and PETG-PTFE and at least the PC-PTFE claims to have coefficients of friction equal to that of the best IGUS filaments.

@eighty-eighth_section Месяц назад

PVDF is also another option.

@axelSixtySix Месяц назад

@@conorstewart2214 There are several aspects to this subject, and the friction coefficient is one, but not the only one. Igus polymers have both a very low coefficient of friction and excellent resistance to abrasion. When using a filament reinforced with fibers, it's the screw that will have to withstand the abrasion. And since it's the most complicated part to manufacture, softer materials are usually chosen for the nut. However, I still believe that, regardless of the quality of the polymer, it will never match the precision or rigidity of metal, especially not in this application.

@conorstewart2214 Месяц назад

@@axelSixtySix the filaments I mentioned have very good abrasion resistance too. Self lubricating and low coefficients of friction tend to go with high abrasion resistance anyway.

Nice! I'm still in the process of upgrading my printers to do high temp materials. That said, PLA never ceases to impress me, holding its own in your break tests. For your functional part, it was fascinating to see that the glass core filament worked so well, trading higher stiffness for some brittleness.

@SianaGearz Месяц назад

The problem i've had with PLA is that while it's impressive out of the printer, 2 years later, loaded prints have all failed. And i've had a printer for 7 years now i think. They have showed yellowing, crazing around pressure spots, and exploded into sharp shards, when initially prints are extremely tough. I rather deal with deficiencies of PETG and HIPS because they don't experience any changes with passage of time.

I think this demonstrates one of the great features of 3d printing. Testing, iteration and development. Not getting into the whole materials discussion aspect going on, i.e. glass fiber and metal wear. I'd think the next step was a nice quality resin print in lost wax material and have some new bronze nut blanks cast, since it is a bit of an odd shaped part to be accurate to the original.

Learned glass cutting that day. I also love how i can just span a piece of plywood or cutting mat into the same clips, though i haven't had to yet, but i'll make a quick swappable toolhead system eventually. I installed Ultimaker bed glass clips, i have them jammed between the nuts and the bed permanently installed in the back of the bed, and below the nuts in the front of the bed. I also don't have bed springs any longer, instead i use nut wheels both above and below the carrier, and during manual bed tramming i jam them into the carrier so the bed won't become untrammed or vibrate.

@MikeKasprzak Месяц назад

If it was a regular mix like most CF filaments definitely a problem, but it being glass-core filament (possibly a glass+plastic core surrounded by a pure plastic), it's possible the outer plastic might protect it (until it wears). That said, I wasn't paying attention to the nozzle size, so depending on the thickness of the glass core, the "protective plastic" might have yielded to the stiffer glass core as it passed through the nozzle. Tangentially, I would expect a CHT nozzle to defeat the purpose of a filled-core filament.

You gave me some inspiration to fix my lathe with 3d printed parts! I have a mini lathe but the thread spinner fell and broke to pieces so I haven't been using it much. But seeing that you did it, i will try my luck. It doesn't have to withstand forces much so it should be fairly easy to build a new thread dial. Very cool, i never through to try and fix it with a 3d printed part until now. I couldn't source another one so I gave up. But I will tey this. I may also try to build a 3d mount to drive it with some stepper motors eventually. If I could move the carriage back and forth maybe I could use a timing magnet to produce threads in synch with a stepper motor. That would be awesome. Not a full CNC machine, but an automated thread would be awesome. Ill have to think about the best way to make it happen now.

@MarcusBuer Месяц назад

For my Z axis on a large scale 3D printer I used IGUS rods but 3D printed nuts (common ABS), because IGUS has nice rods that are affordable, but their nuts are crazy expensive. The way I did was setting the nut area to be 100% infill and the diameter to be equal to the inner diameter of the rods (the diameter without the threads), then I took a cut from the rods (that was an offcut of when the rods were cut to length) and made some perpendicular cuts as an X on the rod, and used a file to bevel it, making a tap out of it. Then I used the tap to make the threads on the plastic material. It was a bit snug on the rods, so I just put the rod on a drill and went back and forth until the friction and heat deformed the plastic to be just right. Then I lubed the rods with lithium spray grease and the nuts lasted for quite some time.

@drt5665 Месяц назад

+1 to all the comments mentioning hardness differences between the plastic nut and the leadscrew. Assuming that the leadscrew is regular high carbon steel, and possibly undhardened at that, the steel is significantly softer than the glassfibers. Once the "Shell" of the coextruded abs is worn through, that Glassfiber will grind your leadscrew within a few hours of usage... (Try rubbing a cutoff wheel at the leadscrew forces against the old leadscrew and see the kind of wear that produces). In addition, i want to mention that even though this is supposedly coextruded plastic, it will still have less strenght (as in stress at failure) than just the base plastic itself. The only polymer type that gains structural stiffness by adding in cf or gf are the tougher, ductile ones. PCTG, Nylon and Tough PC... ABS and PLA are plenty stiff by themselves. Additional Stiffness will only amplify the negative attributes of high stiffness (awful shock absorption, layer adhesion, etc..). Printed ABS is in my experience also one of the fastest wearing plastics right after pla... petg and pctg are way more forgiving on that front. Pure nylon is a also quite waer resistant, though obviously not an option for this project. The best material here would probably be a high strenght polycarbonate filament without fibre reinforcement. Should be printable on that QIDI printer. The main advantage of fiber filled filaments is print quality, as you have documented in this video.

@Brocknoviatch Месяц назад

Another advantage of fiber filled filament is less warping as it breaks up long polymer chains. One disadvantage I have found is that the layer adhesion is better in pure PC vs Carbon Fiber PC. Igus make self lubricating filament, which would be interesting to see if it was suitable for the replacement parts.

It can certainly get you by for a time and even allow you to use your machine to make the final replacement parts. Some parts being 3D printed like the thread dial I think will last a long time, but the nuts... I'm just guessing, but I think they'll have a little more flex than you'd want for highly precise work. My lathe has small parts a larger lathe with larger parts could be a different story. The Standard Modern is a nice machine! I think we're getting very close to being able to 3D print structural parts at home, there is going to be a change in the tech to allow us to use SLS at home, I just saw that the first one is being released for home use in the next few months, it'll be great to be able to print truly structural parts at home without having to worry about layer adhesion etc. Nice work on Self-teaching Fusion, I'm used to it now, but when I first started, it wasn't that easy to wrap my head around.

@sierraecho884 Месяц назад

Niiiiice, this filament is great. There are also different types of glass fillings. There is the "regular" fiber types but there are also spherical balls filling type. Their advantage is that mechanical forces behave better with round shapes, there is no notch effect. But you need to be careful because all those filament are highly abrasive, they will increase wear of your metal parts and probably damage them over time. An other method could be to print a master part and use a low melting point alloy like aluminium or even zinc. If tight tolerances are needed try to create bores, those have a very high tolerance. So for instance you can cast a fairly complex zinc part and then create bores and tap it hight tolerances at home.

@GeckoCycles Месяц назад

I've used the XY compensation in the slicer for threads too till you get the fit you are looking for. Could easily give clearance in Fusion as well which would be the way to go if you are sending out for a machining process. You will have to have different Gcode than your slicer produces. Fusion will do that. Two different animals. I would give them the screw to match the nut to. Chances are that the ACME thread that the screw was made from is not a precision ground screw like OEM would of done. A DRO would solve that inaccuracy at least as far as travel goes compared to your dial on the lathe. It may be acceptable depending on what you are doing. Once you start putting more load on your tool you will find that any plastic is not that good at all. Repeatability will be hard to get but use your print to get by to make a metal one. I would single point that thread. Grinding a HS tool is not that hard to do. THere are good loads put on the tool making ACME threads especially. You could also make a tap out of the old unworn part of the screws to do a final cleanup. Your thread dial needs to be held tight so it won't swing any while cutting threads. You may find that that crappy fix of that screw won't work with a tight tolerance bronze nut or at least it will have a tight spot every turn.

@NeedItMakeIt I noticed at 7:34 you tried pulling the print right off the heated bed. One trick I use, is I have a piece of steel (stainless steel work bench) that I take the plate off and place the build plate on it. I've found this rapidly cools the build plate and I quickly get the satisfying pop and crackle of the build realeasing from the plate.

I reapply glue stick every 8-12 prints. No issues.

this even works with a slightly wet towel, no need for iso, because when heating up the bed all the water evaporates. I tried both and found the wet towel easier to use because it does not evaporate so quickly whilst spreading it out on the bed and you can save the iso for actual cleaning. I also use a wet towel to remove the marks after the print was removed, so it doesn't show up on the next one.

Very interesting printing experiments here but the glass fill material will work with an abrasive action on your leadscrew. There have been some really useful experiments carried out with Acetal Copolymer plastic bar/rod where a piece of leadscrew is heated with a hot air gun and 2 half round segments of the Acetal plastic are squeezed together until no gap exists between them. The resulting plastic nut can be unscrewed from the thread after it has cooled and solidified. The process was nicknamed the 'Evanut' after the guy who came up with the idea. It has been shared many times on home model engineering sites. I have tried it with very successful outcomes. It is easily achievable to get near zero backlash with the 'Evanut' method. If you are going down the route of making a new nut from yellow metal then bronze or gunmetal are far superior to plain brass.

@smellslikeupdog80 Месяц назад

I would've thought bronze filament would have better lubricating properties while staying a bit durable for plastic. Glass fibers, while stiff, are essentially abrasives, and more prized for their strength and chemical resistance; than as a metal alternative. The wall thickness, when forced into close proximity with the glass fibers and plastic; is what gives their mechanical resilliance. Similarly, in injection molding the "fuzz" or roughened surface texture comes from a lack of pressure to force the glass fibers into the part surface against the polished mold surface. So the molten resin is essentially allowing the glass fibers to "float", and not forced into close proximity with the remaining plastic surface. Flame polishing may help the plastic to "wick" into the texture that is otherwise essentially sand paper. Like your content, and this is not intended as a criticism; but I would love if you went into some technical specs, or some of your thought process when making these parts with the materials; instead of simply showing them printing or in use.

So, i have some of this filament in my x-max3 now making a 2kg dry box. But i made mistake. I have gotten into the habit of drying all of my new filament before first use. I do 8hr at 90°c. Well, be warned, the spools quidi uses do not like heat. I came home to find the spool severely warped. It was beyond use. I had to re-spool the whole roll. Thats when i ran into the stiffness problem. Now i have 5 small rolls instead of a single 1kg roll. Also the filament was stuck to itself in many places. Im not sure if it was caused by the dehydrator or if it came from qidi that way. If i hadn't already spent last night re-spooling it, i would have tried to contact them to see what they suggest.

@NeedItMakeIt Месяц назад

This sounds like a nightmare! I haven't had the problem with anything recently, but I have had it with a spool of PETG. It bonded to itself when I was drying it at 60C. The issue was that the heater was pumping out hotter air at the bottom and it caused it to fuse. A way to circulate the hot air in a dryer will prevent this, or a way to rotate the spool.

@Kimberlie1 Месяц назад

I've inquired about something similar before. They gave me feedback that they have two types of spools. The spools used for filaments such as PLA and ABS can theoretically withstand up to 80°C, but in fact if we use such high temperatures it may cause the filaments to become soft. The other type of spools used for filaments like carbon fiber can theoretically withstand up to 125°C. I think they are also considering the limited temperature that the filaments themselves can withstand, so the spools of some of them can't withstand too high a temperature.

I just find all these options print much better than CF-based composites. Also with your load tests, you might want to investigate how different infill patterns and print angles affect the stiffness and robustness of the final part. With composites you get extra strength in the direction of the extrusion, which implies there is some potential for eeking out even more benefits.

@@jackgamer6307 It is completely dependent on your part size, shape and print settings, to some extent the filament/brant etc. If you print a long thin part that's nearly solid it will want to do this.

Textured or no texture won't do much to reduce the internal stresses due to the cooling of the plastic. I agree that the textured surface of the plate does a better job of keeping the part stuck to the buildplate though, that's something that I've had pretty good success with too.

@Noxoreos Месяц назад

Well, I must say that warpage isn't as far of a problem to me, than what is shown here. I tested multiple meterials in very a similar way on a "00" rated surface plate and I managed to get all my test samples completely flat. I'm using a P1P in an enclosed box made from fabric and aluminium foil. The Materials i tested were, ABS, PLA, PLA+, PLA-Silk, PLA-CF5, PLA-CF15, PLA-CF20, PETG, PETG-CF15, PETG-CF20, Qidi ABS-GF25, PC, PA-6, PA-12 and PA6-CF15, PA12-CF20. I was able to tune all of their settings to avoid warping completely. Anything with a highter percentage of CF or GF was easier to print without warping. Oftentimes it very much depends on the part itself and the more material is layed down, the harder it is to counteract warping. Also parts may be stronger under certain conditions, when they are actually not printed solid. Print speed, cooling and temperature are the most important factors to counteract warping. If you feel like you need a stronger bed adhesive, then the settings are probably not good enough, because that means you have a lot of internal stress in the print, which also makes it weaker. Parts printed solid usually also have more internal stress.

@NeedItMakeIt Месяц назад

I think that's the main reason why most people don't experience too much warpage, when we begin to print towards the solid range, the stresses can begin to overcome either the bond with the buildplate, the attraction between the plate and the magnet, or they'll warp during the cooldown. As people want to print larger parts and more solid parts, it will become more important to tune like you've done for the best results. Printing PLA in an enclosure is possible of course, but when it comes to overhangs on parts like I've made here, it becomes way too hard to achieve good results with PLA. I have run some tests after the video, however those tests were all complete failures. Slowing the print speed helps quite a bit, but does not solve the problem. Long-term I don't think that FDM is the solution, I believe that we're going to see a shift to more industrial style printers at home, small scale. Printing solid parts is a good temporary solution though.

I try to do everything myself, but I'm willing to try something new because when you can make intricate parts from metal, it opens up a lot of options. I think if someone is inventive, they can use 3D printing at home to come up with the idea, fine tune it and then send it away to have it made for a part that can last a lifetime and depending on what it is it could maybe even become an heirloom or part of one anyway. I guess I need to wait and see, I'm curious about the process, the pricing seems far better than what I was expecting, that last time I tried this process was 3 years ago and I suppose the tech has improved quite a bit since then.
