Just wanted to say thank you for this. Your video has ended a 1 year struggle with ABS! I don't understand why everything I read on printing ABS was quite so wrong. Read to print slow, never use the fan etc. I am not using any adhesion agent, but I am printing at a higher speed and using your tips on the slowdown and fan speeds and magic is happening, thank you so much!!

I'm glad I could help! It's been the same for me and I always wondered how some people were able to print ABS so flawlessly...

Thank you for a great video. Currently I am at a point where I can print with ABS and get very good results. Here are the things on my list: * CR-10S (30 x 30 x 40 cm build volume) * Print on glass * heat enclosure I made out of a large carton box (openings for control unit to be outside of it) * Bed temperature 80 degrees C, nozzle 235. * Printing speed between 60-30 mm/s, acceleration down to around 5-10 mm/s/s. I would think this ensures better bonding at corners, preventing layer seperation. * Layer height around 0.12 mm, also experimenting with thicker layer heights. * Something I picked up recently in another KZread video, a cover at the bottom of the hot end enclosure to divert the air blowing over the hot end away from the object you are printing. Not sure if this is only limited to the Creality machines but it seems to be a game changer for me. * Bed adhesion... A couple of years ago I found that applying spray on clear lacquer creates a very sticky layer on a glass surface, so much so that the ABS printed wonderfully but sometimes even ripping out chunks of glass after it cools down. More recently I read of a mixture (50/50) of white wood glue and powder sugar. Currently a combination of these substances provides great results for me. Basically I just need to reapply a diluted solution of sugar and glue to the glass, a bonus is that you do not need to expose yourself to dangerous fumes like acetone. * Brim and mouse ears: a brim is usually mandatory when printing with ABS. I found that using mouse ears (about 20 mm diameter and 0.6 mm thick) works well for longish, rectangular objects.

I use spray adhesive to coat the bed plate first, it’s cheap, easy to apply and works every time on ABS.

Hey. thanks for the tips. I print the Prusament ASA with the standard Prusament ASA Profile in my Lack enclosure on my MK3. I print it on the textured sheet without any adhesives. The only thing I found very important to have is a draft shield. Also try activating the brim and - since you won't need it for the part itself - move it away from the part and under the draft shield to hold it down in case it warps from drafts. works very well for me. Also I can strongly recommend Vision Miners Nano polymer adhesive as an all purpose adhesive. It is amazing.

I have a glas bed and use normal PVA glue as a slurry, that I thinly spread out with a spatula while the bed is heating evaporating the water. I even reuse the coat multiple times by just spraying the bed with water when it's between 40-50°C. It works well most of the times, ABS is just notorious. The most satisfying part for me is when everything is dialed in and the part auto releases from the bed when it's cooled down.

Consider yourself lucky. For some reasons I always needed at least a bit of glue. Even for PETG on a Prusa PEI bed, textured and smooth.

I've had really good adhesion using a sheet of PEI lightly sanded with fine grain sandpaper. No other adhesive needed. I run the bed temperature at 115 degrees and it helps with warping. 20% cooling with a single turbine fan. It's a modified Mega S that gets fairly close to a Prusa in quality. The only limitation is I'm using binder clips to hold the sheet down to the bed as a magnetic base will weaken at those temperatures and I don't want a glue mess when I inevitably replace the sheet.

@SmallBatchFactory

6 ай бұрын

That sounds really interesting! Do you have any long term experience? I'd expect that you need to sand the PEI regularly to keep it sticky. The Prusa uses special magnets that don't weaken at those temperatures. But their heat bed cover does warp.

@keyboarderror1

I've been using this setup for about three years now. I've replaced it a couple of times. Light sanding with an alcohol wipe for a smooth surface is good if you want a clean print face. Doing it a lot wears it out more quickly. I don't worry about that too much. Adhesion is almost too good. PETG will weld itself at any temperature. It IS easy to mar. I've managed a couple of Klipper head crashes (no end stops) driving the 250 degree nozzle into the bed and leaving a divot on one side. It doesn't go through so I just flip it over. If there's magnets available that have a curie temperature high enough you could get a PEI coated steel sheet. I'd be curious if there's any aftermarket equivalent available. I haven't seen anything. I was thinking an electromagnet failing all else. The clips will only hold it down around them and I have to mind the clearance with the print head on larger prints. For most of what I print it's great and minimal hassle. @@SmallBatchFactory

@SmallBatchFactory

To me it sounds rather expensive if you have to replace the sheet once in a while. My glue bottle is still half full after all these years so the costs seem to be justified. PETG most definitely needs a thin separation layer of PVA, at least that's what I always used. I've drilled a groove into my Vorons sheet as well. The endstop is still not reliable for me. The mesh works fine though. My Prusa has a permanent Benchy hologram from forgetting to switch the bed settings. Haven't tried anything above 110c since the thermal fuses I have installed would stop me.

I would love to see more abs/asa tests. Like temotowers in different configs and stuff just to demonstrate these things.

Issue with temp towers is they don't represent real world printing. Since they're small they printer needs to slow down. Back when printers were generally slow this worked fine IMO but with today's high speed printers it already makes a big difference how large the model is, meaning print time per layer.

So far, I have not had any issues with bed adhesion, nothing but PEI steel, but cooling needed some tweaking (eSUN ABS+, 250C/105C, about 40-45C chamber temp, E3V2, klipper, Dragon HF, Sherpa Mini, 2x5015 12V fans at 24V, Manta MK2 ducts, dual Z, Mag PEI, Comgrow tent enclosure)

@SmallBatchFactrory - I find I achieve the worst print results using ABS filaments that were declared 'new and unopened' on eBay! 🤔 As I only print single items and in occasional low-volumes, I find keeping all my used reels in hermetically sealed plastic flight cases with silica dry bags, dramatically reduces moisture ingress and delays premature degradation, also negating the need to 'heat box' dry my reels as frequently when using them so sporadically, I also find cutting off the amount of ABS filament I require, also reduces exposing the remaining filament to unnecessary ambient moisture. 👍 This is my particular method of madness, I could be wrong. 😉

@SmallBatchFactory

To be honest I almost never dry any filament at all. Apart from Nylon and Polycarbonate, which I keep in a sealed dry box even when printing. I have spools I opened years ago which still work great. The only ones showing a bit of moisture absorption are a few PETG rolls, but still totally usable if you don't need those last 10% of print quality. Granted I live in a 50% humidity area. Probably way different if you live in a very humid place.

Sounds like you need a pei sheet. My Ender 3 is printing ABS and ASA like a champ in a tent enclosure on a cheap PEI sheet with no brim and no glue. 255 nozzle and 105 on the bed.

Never had an issue printing on a glass bed with and without hairspray once I dialed im a few other factors. Key is chamber temperature above 35C, bed temp of 100C, print a bit slower, zero or very little cooling, and increase the flow on the bottom layer so it really squishes that bottom layer into the bed. I think fan cooling can cause additional issues. A better approach I've found is to set the minimum layer cooling time in the slicer. This slows the print to allow the layer below to cool sufficiently.

@SmallBatchFactory

6 ай бұрын

In my humble beginnings I had the experience that printing slower just resulted in more time for the print to warp for some reason. We printed a lot of faceshields in 2020 and the faster I printed the less I had warping issues. I didn't use Magigoo back then. That was the only occasion where I printed so many of one model that I could really adjust the settings. If you have time to spare you can of course just slow down the print instead of fan cooling. With the full plate I showed in the video I needed no cooling at all since every layer took long enough.

I think it depends on what kind of printer you have. A bed slinger moves the print back and forth which is basically like having light cooling.

Apparently it meets all the requirements for printing ABS as well as other engineering grade materials. However the printer is not enclosed it's an open frame bed slender. I did purchase a tent like enclosure, more so to maintain a consistent temperature in my workspace and to keep pet hair away from the printer. However I'm curious If this printer should be fine printing ABS parts. So one of the concerns brought up on Reddit is related to heat and temperature that might be generated if you enclose the printer. I think the concern revolved around stepper motors as well as the motherboard. However there seems to be a bit of a debate on if the printer could generate enough heat while enclosed to even damage the components. The manufacturer doesn't recommend an enclosure, but again there's debate as to why this is the case. Some argue that it is because of potentially damaging components, others say it's more to do with product differentiation and getting people to buy more expensive printers. I'm curious to what your thoughts on this might be? Any and all feedback is greatly appreciated. My other question is regarding the fumes generated by ABS and certain filaments. There is a device some use called a bentobox that uses charcoal, HEPA filter and some fans to process the air within an enclosure. I was wondering if you have any thoughts on the effectiveness utility of something like this. Obviously it would still be used in conjunction with having a window open and not being in a completely enclosed space. But I'm curious if such a device is even worthwhile. Again any and all feedback is much appreciated. Thank you kindly, much love and gratitude. P.s. pardon any typos as I was using speech to text while walking to write this.

Hey Whyired, nice to read you again! The biggest issue with enclosures is having the power supply inside. It's giving up quite a bit of heat and will get pretty warm inside. Having it inside an enclosure regularly will wear it out quickly, occasionally for a few hours should be OK. I don't know where the A1 has its supply, I guess below the print bed. So one thing you might be able to do is put it in a table with an opening in the bottom for fresh air to the power supply. Best scenario would be having the PSU outside, rewiring the printer. That's what I did with my Prusa. For the steppers the heat is no issue. The controller board should be able to take the heat as well. Heat always shortens the life span of components, but usually not in a meaningful way. Think of how hot a PC or Laptop gets inside the case while still running perfectly fine. A charcoal filter definitely helps filtering a lot of nasty fumes. They're actually mostly particles, not gases, and can be filtered pretty good. I built one for soldering for example and it makes a huge difference. Just don't forget that you have to replace the filter material pretty regularly. I have yet to build a filter for my Voron 0.2. It's already accumulated a film on the panels from printing ABS which a filter would definitely help avoiding.

Magigoo, yes. But I still get warping if I cool the print down too quickly. I've had some success letting it cool gradually at 5 degrees per 5 minutes but the edges still curve up a little on the larger prints. I think my next bet is to just let it sit on the plate, covered with a filament box to make a mini oven, and let it heat soak on a 100 degree build plate for an hour to relieve the internal stresses.

Are you talking about rather flat prints? For what I usually print the parts are over 5cm high. I get a hot bottom, cool middle part (~40c) and a hot top when the print finishes. Means the middle is already cold enough to not warp anymore. If the print is only a few millimeters high I'd expect the result you mentioned.

​@@SmallBatchFactory Nope, it was tall. I was printing the feet for a Voron 0.2 with Mouse Ears, but no Magigoo, and the corners lifted when I let it cool naturally (bed heater off immediately) instead of letting it cool slowly over an hour (-5 degrees every 5 minutes).

@tasa4904 that's interesting, how much glue did you apply? I literally popped my Voron parts off the minute it stopped printing to immediately start the next print.

@@SmallBatchFactory If anything, I had the heater bed running at 110 degrees to make the part stick without glue (bed top is about 10 - 15 degree cooler than stated temperature). Pumping that much heat below while the upper part cooled to about 40 to 50 degrees ambient temperature might have done something. Although I would expect the warp to go in reverse / create layer separation since a layer is supposed to contract on cooling, not expand... The only reason why I know that it warped on print completion is because the mouse ears were firmly stuck to the bed right up until the very end. Then I walked away and let the print cool, and came back to find the mouse ears had detached and were in the air.

@tasa4904

Thinking about it further, I think the reason why it warped upwards is because the heat transmitted from the bottom of the print flowed to the middle layers. And then the bottom of the print cooled down quickly because the build plate is thermally conductive and equalizes quickly with the ambient air once it isn't actively heated. With a hot middle layer and a cooler bottom layer, upward warp. Next experiment then is to use Magigoo with a bed temperature set to 80.

How would you print thin walled (2-4 walls) ABS parts? I got 65°C chamber temp and using the fan at 20-30% makes this part weak for the layer adhesion. Only 0% fan makes these parts strong, but messes up all overhangs :(

@TheWuzyy definitely! You can go totally overboard with squishing. 200% of the Nozzle width usually works fine, even up to 300 is manageable. We printed face shields when the pandemic started and I optimized my GCODE with wider layers to save 70% print time.

I like HIPS. I think it's underrated. I don't see much point in ABS to be honest for the trouble it causes. Their temperature endurance is really similar as is the cost and mechanical and chemical properties. HIPS prints come out pleasantly slightly matte. Yes i think a consistent amount of airflow is needed, so i run a slow PCF speed. Adhesives i've been happy with is Deli 7091 glue stick and self-made PVP solution, both work well. But then working with HIPS isn't nearly as demanding as with ABS as it doesn't exhibit excessive swell or shrinkage, so the experience needn't carry over.

1: Just scuff your pei with a scotch pad thoroughly, clean with dish soap, maintain with 90% or higher IPA - no need for glue stick 2: The higher the chamber temp (up to a point) the better. 50C-60C is great. At these chamber temps you can even run the part cooling fan at a low speed - 50% or below based on your part cooling setup. 3: Bed at 110C, Hotend anywhere from 240C to 270C (yes 270C). These are the only changes I make compared to printing PLA, and my parts come out absolutely perfect. Really the key is chamber temp. The lower the chamber temp, the more problems you'll have.

IDK why you insist on glue when PEI and a chamber above 40c is all you need. I run my bed at 100c and apply a brim for parts lacking surface contact other than that as long as the chamber doesn't drop below 50 after a couple hours it will always complete successfully. Another thing I will do if its a part that needs dimensional accuracy is leave the heated bed on and slowly ramp it down for a hour or so to eliminate warping due to rapid cooling.

@SmallBatchFactory

My chambers don't get above 40c. A PEI sheet and 110c bed temperature wasn't enough for me in the past. I also rather use glue than remove a brim afterwards. If that all works for you then there's no need to change anything. With glue I get dimensional accuracy without a slow cool down.

Haven't tried that. I guess there's no improvement to "sticks without problems" except for the price.

Another factor: the printer itself. The Prusa Mk3 and other printers with light weight beds just don’t print ABS very well. Printers that have a lot more thermal mass in their bed (like the Voron) print far better. I’ve burned a LOT of time trying to make the Mk3 print ABS well-enclosures, active enclosure heating, many variations on settings-and it will never do as good of a job as the Voron.

@@SmallBatchFactory 100% agreed on good bed adhesive and light part cooling fan-I discovered both of those the hard way, too! And the Mk3 will print ABS acceptably. The Voron just prints it better, with fewer flaws and improved surface quality. My old LulzBot Taz with its heavy glass bed also printed ABS really well. I believe the thermal mass of the bed is a factor but I could be wrong; it could be as simple as the printer parts being made of ABS rather than PETG.
