It is common knowledge that higher technical materials should be printed in a heated chamber. But why do they warp less when printed in a warm environment, and how much stronger do they get? I used the QIDI X-Max 3 with its actively heated chamber to test exactly this out and investigated the layer adhesion of ESUN ABS and Prusament PCBlend when printed at different temperatures! Let's find out more!

@victorsoh7891 7 ай бұрын

Just my personal opinion: it ultimately depends on the materials that one commonly prints with. Active chamber heaters are commonly PTC and can be an electrical hazard if not implemented properly as seen in this video, kzfaq.info/get/bejne/bpd9kpek0LLehYE.html&pp=ygUKcHRjIGhlYXRlcg%3D%3D. However, printer manufacturers who target the prosumer market should delve more into this aspect. It's not entirely illogical to assume that the buyers of such printers are interested in making usable parts for their business. This is the way forward. It is what Stratasys, Markforged, 3DXTech, Essentium, etc. are doing - albeit at much, much higher chamber temps and point of entry.

Stefan, Ich besitze den x-plus3 und möchte nur darauf hinweisen dass man definitiv vorab das aktuellste Firmwareupdate auf den Drucker laden sollte, bevor man mit ihm richtig druckt! Die Updates bringen in meinem Fall fast immer signifikante Bugfixes, Performanceverbesserungen, und sogar neue Funktionen! Hast du das Video denn überhaupt mit der aktuellsten Firmware des Druckers gedreht? Gerade dass die Chamber-temp. nicht den Sollwert erreicht kommt mir etwas verdächtig vor…🤔 Toller Content in jedem Fall, ich bin ein mega Fan deines Channels 😍 English. I own the x-plus 3 and realized the importance of their Firmware-Updates for their ner Devices, as they will always at the very least improve the printer‘s performance (like the bug that was shown where the enclosure didn‘t properly heat to the set temperature) and in most cases bring some added functionality for the on-screen menu, and at the very least make the printer more reliable! So I am now wondering if you did start the Video about the Printer with the latest firmware installed, as many reviewers have complained publicly on youtube about problems like bad printing quality and bad performance due to some bugs and missing features, just because they didn‘t even bother to install the latest firmware and were hence reviewing a device, literal months after Qidi released an update with all their issues fixed🤦🏽‍♂️

I've been waiting for you to make this video for years. According to a friend who has a printer with an active chamber that goes up to 100 degrees Celsius, ABS needs 70+ degrees, optimal is 80 degrees. At that point the print orientation doesn't matter. 70 is the minimum accordning to him, I imagine if you had a printer with 80 degrees you would get even more increase in layer adhesion.

@zanmarinic 7 ай бұрын

I made an active camber myself... above 65°C you start to get issues with heat creep... for 70°C+ you need a watercooled hotend, otherwise you jam your nozle with biger prints..

@hc3d 7 ай бұрын

I run my machine at 70C and use a watercooled extruder stepper. Despite this I am bottlenecked by extrusion speed. The external dryer also runs at 70C. In the summer the watercooling radiator is not powerful enough and extrusion starts to fail if I let room temp reach around 30C. So I use AC to keep room at 25C. In the future, keeping the filament at 25C prior to reaching the extruder gear might allow faster print speeds on my machine.

@@redboom9874 It depends how good the heatbreak and fans are. Fans differ a lot in performance. With a heated chamber cooling requirements increase dramatically. The goal is to cool it slightly below glass transition temperature and let it stay at that temp for the entire print. Glass transition for pure ABS is like105 Celsius. I think the filaments have additives that make them more printable and that's why they have lower glass temp at 90 C.

@Rob_65 7 ай бұрын

As you mentioned, the heated build chamber will give the layers more time to melt into each other. This also explains why slower printing resulted in stronger parts in some of your previous tests. Another issue to take into account is shrinkage. PLA shrinks about 0.3 - 0.5%, ABS 0.7 - 1.6% and ABS/PC Blend 0.3 - 0.6% (depending on the type of blend). Nylon (PA) is even worse. Depending on the type this has up to 2% shrinkage making it very prone to warping. Adding glass or carbon fiber as a filler material reduce shrinkage so those are easier to print. I think there is uneven shrinkage during cooling and most shrinkage might occur as soon as the temperature drops well below the glass transition temperature. This could also be a reason why materials like ABS (Tg = 105C) and PC (Tg = 145C) almost require a heated chamber whereas PA (Tg 45 - 70C). It would be nice to compare especially ABS and ASA in this respect. Both have around the same Tg (ABS 105C, ASA 100C) but ASA has a lower shrinkage (0.4 - 0.7%)

I used a cheap food dehydrator as the active heater for my TEVO monster enclosed by cardboard panels. Although the camber temperature maxed out at 50C I was getting ABS prints at the same quality as PLA, and ABS was my standard filament in that machine. It also helped to have the part cooling fan set to 10-15% during printing.

At work I run a fully enclosed industrial printer with water cooled heat break and motors, and a chamber temp up to 135C! The heated chamber definitely makes a difference. I never get parts detaching from the bed or layers delaminating. I'm still working on figuring out how to prevent the filament from curling up on steep overhangs, though.

I built a heated chamber for a printer years back and the goal was 70c and I learned A LOT from that. 1) Don't use a bed slinger! Core XY is a must. It helps keep the plastic and electronics out of the heated chamber. You don't want the plastic to be soft before it hits the extruder gears. 2) Don't use acrylic for something going that warm, at least not thin acrylic. It will soften and sag. 3) If you're using a metal frame, definitely consider water cooling your motors. Especially at around 60-70°c your motors don't like running that hot constantly. A metal extruder will cause issues as well.

Stefan, great video and I was waiting for this since a looong time from you! Now there is finally someone in the community who is addressing this issue. It's like MirageC and the importance of drying your materials, which is a must in injection molding. Why not in FDM / FFF was really suspicious to me > materials are the same. About your findings I can give you one hint: the Tg (glass transition temperature) playes a hughe role here. My rule of thumb is to know the Tg of the material you want to process and use at least this temperature (sometimes +10°C, depending of the heat distribution in the chamber) as the chamber temperature. This is how you process polymeres right. As an example and this is why Stratasys was going with a heated chamber: 1989 there was now material for the AM (FDM / FFF) technology, only injection molding grade material. So, to print real ABS you had to have a chamber with elevated temperatures to deal with the shrinkage. Really interesting stuff if you think in the approach of physics and why it is not possible to print PEI (Ultem) on an open machine > Tg of around 217°C. The temperature difference is too high. Keep on going and never stop producing great stuff! Greetings Andreas

Stefan, another excellent test protocol and excellent video. I’ve done a lot of testing with active chamber heat using a very hacked-together system. I had very similar results to what you’re showing. Where I got stuck was trying to make a more production-grade system; I couldn’t find a 24V active heater which I could integrate easily and safely. (I’m also not a hardware guy so I needed something really drop-in.) I was especially worried about fire safety. Once I bought a LDO Voron kit with its huge heat bed spreader I figured the problem was sufficiently solved. I could add a little bit of air circulation to that and get reasonable chamber heat as a secondary effect.

It's interesting that you were only able to get 65 C chamber temps with active heating. With a passively heated enclosure, that's typically pretty easily achievable. If you want to get above that, the "blanket mod" (i.e. put a blanket over your printer to keep in the heat) does wonders. Rather than active heating, I would prefer that manufacturers implement better insulation so that less energy is used during printing. Bed heaters put out PLENTY of heat to get a chamber up to ABS printing temps.

Just a headsup for Voron owners: You can get quite high on chamber temp using methods that, essentially, blow air at the bottom of the heated bed, causing it to run at a higher average power and thus put more heat into the chamber. I use a combination of the Nevermore V6 (activated carbon filter) and two "BedFans" (both mods can be found with a quick Google search) on my 350mm V2.4 and I have seen chamber temps as high as 72C after a good heat soak and a few prints. ABS prints like an absolute dream in this situation. I haven't done any "real" layer adhesion testing, but I know it's damn good, much better than without the filter/BedFans. Of course these mods can probably be done to any enclosed printer as long as the bed heater can manage the extra load. The biggest disadvantage is that it does take longer to heat than a true active chamber heater, and also the fans used will fail prematurely due to their close proximity to a 100C bed.

Very tempting printer especially being integrated with Prusa slicer (ex-slic3r). This is pretty much my experience with ABS on my original Ender 3 - I built an enclosure using that 1" pink foam stuff that builders use for insulating houses, and inlaid aluminized bubble wrap. Cut a window in it for a flap of perspex and it works really well - temperature gets up to around 65 °C too just using the bed at 105 °C. Also uses less electricity because less energy is needed to keep up the bed temp. It takes up a lot of space though, but is a cheap solution. Plus, the enclosure is also a useful box to store freezables while defrosting the fridge freezer!

I'd be interested to see how PETG benefits from this. I've been running into issues with it that I haven't had before, but the weather is getting colder, so the ambient temps in my basement are dropping. Going to be getting an enclosure for it, I'm sure that will help, but I'd be curious to know if active heating helps even more.

@fivepointeightnate 2 ай бұрын

Fun fact with the Xmax3: If you put a towel over the top to keep the bed heat contained inside the unit it will stay about 52c or 125f while printing ABS. That is without using the chamber heater at all!

@Blubb3rbub 7 ай бұрын

I wonder if there are any differences in how you cool the parts after taking them from a heated chamber? Is there any benefit in slowly ramping down the temperature in the chamber in comparison to taking them out and "shocking" them with "cold" ambient temperatures? What happens if you throw them in ice directly after printing?

@CNCKitchen 7 ай бұрын

I'd guess that cooling them down not too rapidly might make sure that internal stresses are as low as possible, but I think there isn't a big difference, when printing at 65°C. If you go all the way up to 100°C this might look different, though.

@spectermk1 7 ай бұрын

In extreme cases you can watch it warp and crack in real time if you cool it too fast. That is if you take it out hot off the "oven" and put it at room temperature. Not sure what happens if you throw it into a bucket of ice water though, but I'd imagine it only gets worse.

@madmatrac 3 ай бұрын

depends on thickness. while standard 2 wall parts doesnt suffer, thick 1cm wallers willl bow bend immideately. so when i do huge chinks i let them cool down in chamber for up to 4 hours to room temp, it release internal stress.

Would you consider a bake off between 3DXTech Ez PCCF and Prusa PCCF, and include a test for heat creep of the printed parts (not nozzle heat creep)? Several folks on Discord are complaining about heat creep on Voron parts printed in Prusa's PCCF in warmer chambers (but still below 100C).

@kasiya2660 7 ай бұрын

Question, i believe while you were printing you had the part cooling fan on, assuming that you were printing the same file for each test with just the enclosure and heater being different, wouldn't the fan be cooling down the print more when the ambient air temp is lower? If thats the case, the increase in strength from having the chamber heater might be reproducible by just turning down/turning off the cooling while printing.

@CNCKitchen 7 ай бұрын

Good point. I had it on 10% all of the time and for all prints and of cause that increases cooling at lower temperatures. Might check that at some point.

The first printer I ever used was the Stratasys 1200SST and it would print the Stratasys ABS in a chamber that was heated to around 170C. Those parts came out super hot, but I still have some of them from about 20 years ago and I never saw any of them delaminate. I don’t know when we will see chamber temps that high on consumer level printers though. Edit - The chamber temp was 170F not 170C.

@blahorgaslisk7763 7 ай бұрын

170°C chambers seems unlikely that we will see in hobby printers. Also how did you avoid heat creep? From what I've heard. Note heard, not experienced, you start getting heat creep in ABS if you go much above 90°C chamber temp. Now if that 170° was Fahrenheit it would translate as 76°C, almost 77 degrees, close to the 80 degrees some people have been talking about as the "perfect" temperature for ABS. Some claim that for ABS a chamber temperature somewhere around 80 to 90 degrees makes the layer adhesion good enough it doesn't matter the direction you test the strength. Layer direction or at a right angle, the strength is the same. Again this is something others claim, I'm just trying to make head or tails of this.

@KellyBC 7 ай бұрын

@@blahorgaslisk7763 Ahh, you are correct I was thinking C but that was the Fahrenheit number. It was a LONG time ago for sure. I still have that machine, although it isn’t functional any longer. But I checked and the chamber temperature on it was 170F not C (so it was running around 75C). That is probably doable for consumer level. The nozzle would print around 300C. Their “ABS” was a special blend of ABS also, I remember them saying that it was not pure ABS.

@danieldeutschen7714 7 ай бұрын

@@blahorgaslisk7763the key is to separate the printing chamber from the rest of your components and space. One example would be the use of bellows: only the nozzle sticks into the "hot chamber", while the mechanics and cold end are much colder. You don't run into heat creep problems, plus you can heat the chamber far beyond the limit of normal EPDM belts, which is at 120° long-term, 135° short term

I’ve been using heated chambers for some time now, one thing you may have missed is, with a high chamber temp, you can use part cooling on ABS, ASA, PC and Nylons without compromising layer adhesion or suffer any warping.

@CNCKitchen I've been curious about the effect of multi-material printing on part strength. Many people with AMS/MMU systems like using incompatible materials (PLA with PETG and vice versa) or soluble materials for support interfaces. Since the AMS/MMU both use a single nozzle for these multiple materials, some amount of material contamination seems inevitable when the previous filament is purged. Does this reduce part strength on the layers where filament changes occur? During a filament change, the printer pauses for an extended period of time allowing the previous layer to cool more than would otherwise happen. Does this additional cooling also reduce layer adhesion and part strength? Some specific test ideas: a) control group: printed normally b) filament change group: a filament change is made to an incompatible filament (and/or a soluble material) which is used to print another object (or which is just purged through the nozzle between layers, simulating both the material incompatibility and the delay during filament change and printing of support or support interface) c) pause test: an artificial pause is inserted between layers to simulate the delay one would experience while swapping materials, printing another object, and swapping back d) incompatible materials test: an incompatible (and/or soluble) material is purged through the nozzle between layers quickly enough that the additional time between layers is negligible and/or in an environment in which the part cooling between layers is not an issue (eg an enclosure/heated enclosure) You could also go further: testing different purge volumes to see if there's a critical point that eliminates contamination issues, or seeing if there's a critical layer time at which part strength drops off massively, or seeing if there are material combinations (PLA as support for PETG vs PETG as support for PLA) that give better or worse performance relative to a single material print. Here's a link to a discussion in Bambu forums discussing the issue along with some anecdotal evidence for potential causes: forum.bambulab.com/t/major-interlayer-strength-differences-when-multi-material-printing/22661/3

I recently got the acetyl/POM filament printing consistently in my bambu. It is probably the strongest material I have every used by a long shot, and I am more and more convinced that it is the next popular engineering 3d printing material. I could not break a 8cm z height 8mm diameter tube by hand while all the other ones broke easily (I train powerlifting). POM seems to have a perfect layer strength, reaching a true isotropic behavior, since the fracture plane is always 45 deg. However it does suffer from a whopping 120ppm thermal contraction, so the width of the part is limited to around 3cm for x1c @ 50c chamber temperature. If not for the warping, POM would actually be quite a pleasant material to print, with no stringing, sticking, oozing, good dimensional accuracy, and post processing machinability. I wish there would be more printers with actively heated chamber and possibly with higher temperature limit at around 100c.

Our Stratasys printer (at work) from 2006 heat up the chamber to 75-80°C with ABS430, and the Stratasys F370 depending on the print heats it up to 80 or 90°C with ASA. The prints at home with a regular printer are definitely weaker, much much more. Never thought that might have to do with the heated chamber though.
