I started printing in hard mode (ABS) from the start just for the reason that PLA can deform easy on hot days in several places and I wanted my prints to last. The 3D printer I use is the WanHao Duplicator v2.1 and I learned a lot from the start and what works best for me. Don't try to print ABS if you don't have a heated bed on your 3D printer. I made a cheap enclosure by stacking 2 Ikea Lack tables on eachother and used polycarbonate plates in combination with 3d printed parts to fill up the gaps and added led lights. An enclosure is almost a must to make sure that the the whole print stays warm without any drafts that can cause cracks (and it makes a big difference with prints that are higher), and it can even help a bit with the electricity bill because it is easier for your hot end and bed to keep the temperature. When the print is done I keep the enclosure closed while it cools slowly as a whole, because if cool air hits the side fast it can still crack even when you are done printing. Mostly when it cools down enough the print pops off the glass plate with a loud noise and that is the moment I know I can safely take out the print. I use 3DLAC (comparable to hairspray) as an adhesive to make the print stick to the bed. With the settings I disable the fan that normally blows on the hot end, and I print slowly so the layer has more time to cool. I also use a setting to pause between layers if the layers are printed within seconds so I can prevent burning the plastic or a molten blob of plastic on top of my print. When you start printing ABS expect many failed prints and it is trial and error. Just Look at what happens (keep an eye on it while printing), find tips on how to solve it, adjust settings and repeat. Start with small prints first to solve adhesive issues with the bed and to make sure the first layer sticks well enough. After that challenge yourself by printing higher, and later try prints with a bit of overhang and find the limits on what your printer can do with ABS.

@Clough42 I struggled with ABS for a long time and then added a simple chamber around printer. No additional heater, bed at 110C for first layer, 90C for the rest and the chamber heats up nicely. I have a 80mm fan on top connected to an air duct going out the window. With the fan running very slow I get a bit of negative pressure inside the chamber so no smell in the room and the chamber is kept nice and hot - I measured it just above 40C. The non obvious part of the equation is turning on the part cooling fan 50-100% of what you'd normally use on PLA with no enclosure to help cool the part enough so small features don't curve up. My surface is aluminum tooling plate (and badly warped MK2 aluminium bed on the second printer) treated with glue stick or similar product. Now-days I use a fluid variant formulated for 3D printing, but regular stick works just fine - just apply over 50% of the bed, take a moist cloth and smear it all over it. You can re-smear it between prints for a long time without adding additional glue from the stick. Putting it on thick mostly works, but it's visible on the part and not necessary. Only negative is my chamber is made from cardboard so flammable. On the other hand printer is Ultimaker cut from plywood so also flammable. Consequently, it never runs completely unnatended but fashioning the box out of thin aluminum sheet is not beyond most peoples capabilities (leftover sheets from offset printing are usually available and cheap secondhand). I haven't had an ABS part fail from warping in two years now and I printed some questionable designs.

Thank you for the great video. Just a small comment on the flat/curved bed. I had Anycubic for 2 years and bed on that thing is really bad and not flat. They way I compensate curved bed is by doing "perfect first layer" - name of the video is "Removing Initial Layer Strings Cura UPDATED". I did use his suggestion and achieved perfect first layer that did compensate bad bed level. So I had stock bed and all the hardware from Anycubic and I dont have to modify my printer to battle flat bed. Also "perfect first layer" does help with adhesion. PS: For Anycubic users you have to do "perfect first layer" for the part and the brim if you use the brim for PETG or Abs. Also I dont use glue doing "perfect first layer"

Ss I put off using ABS for a long time because people say it's so hard. Now I prefer it for a lot of parts. My tips are - Make sure your bed can hold the high temps, the larger the bed the harder it has to work. My 300Xx300 has a hard time even with a 24 volt power supply. My 220X220 has no problem even with 12 volts. I set my bed temp to 90. I turn off all part cooling in the slicer. Sticks best for me to blue tape. Print at a slower speed, you know just don't go crazy fast. I keep a large 30 gal. garbage bag I cut down the sides to wrap around the printer to hold in the heat. You don't have to go crazy with the fit or it will get too hot. I have the stuff to build an enclosure but the bag works fine. It does, have an odor but nothing overpowering but I could see if you had multiple printers going at once it could be get bad. So if your putting it off give it a try makes great strong parts that aren't as rigid as PLA.

Congrats on a great and technical video!! absolutely correct so many things!! ALOT of variation between makes and even colors! To remedy the whole warping thing what i have found that works well is pre heating the enclosure to about 50°C. Bed adhesion goes without saying, hairspray is also my go to, ABS Is way more sensitive than PLA, but the main difference I have found from PLA is the mere viscosity of the plastic when melted. Bed temps from 80 to 90°C is fine. To print ABS well you have to get the extrusion (and retraction) really dialed in. Again, this will vary from make and colors.

The ABS qualities and differences are sometimes enormous...depending from chemical composition, Acrylonitrile is the crystalline part, Butadiene is the rubber part, Styrene is the third part of the compound...True it can be a pain in the neck if you swap roll and the material compound mix is not similar. If the ABS is shiny then the Acrylonitrile % is higher...referring to the rest of the compound,,,and so on... What I did is to heat 45°C to 50° C the bed, hair spray, which is part Acrylate, and then also have a reduction of the cooling...from 75 to 80%....keep warm but not too hot...because the material could also warp... ...my printer also has 3 side covered...but I made a cowl for the top to avoid heat dispersion. ABS is a good material ..the parameters ...once gotten right...it is almost a pleasure!

I cut my teeth on borosilicate with Aqua Net. It gets the job done, but I'm spoiled by spring steel and PEI these days. Fun trick: If the glass is really crusty and gross, you can clean it off with a generous dose of hair spray and a little elbow grease. After working with BuildTak for a while, my conclusion is: Never work with BuildTak, it's a consumable item. The BuildTak sheets one of the office printers I use would last a month or two under heavy printing and regular cleaning, while their PEI sheets are easily lasting more than 5 months (the PEI surface on the MK3S sheets cracked and failed after over 2 years of service). They're probably designed more for their flex plate system, because you don't need to take a metal tool to pry off the print and scratch off the acrylic surface. Certain shapes will shrink more than others, especially corners. The reason why brims, rafts, and mouse ears are suggested for ABS bed adhesion is because slicers will put round corners on them (brims and rafts), and circular shapes distribute the contraction force evenly around the curve. Sharp angles, on the other hand, will concentrate the force on the point of the angle, causing it to warp right off the print surface. Enclosing the build volume could probably help more than a brim. I've had a brim ripped apart by warping ABS. Probably too much mass extruded in a cold drafty environment, but it was still impressive. Quick tip about mouse ears: Since the point is to increase bed adhesion through surface area, you can put them to one side of the part, meaning it's just 1 snip with flush cutters to get them off (I do this because otherwise the MK3S print bed can't accommodate more than 1 visor). It worked with PETG and blocking the draft from the office HVAC system, but I don't know if it'll work with ABS.

For anyone wondering, CURA has this as a plug-in. Go to marketplace in the top right corner. Download the plugin anti warping tabs. Then restart cura. It will add a button to the bottom left corner for adding the tabs.

I learned heaps from this - many thanks - understanding why there’s no silver bullet for bed adhesion. Have you tried sugar dissolved in water as an alternative to hairspray. I get bottom layers that shine and it’s reused many times like you’re baked on comment.

2 years late, but my go-to surface for ABS is heavy kapton tape + ABS slurry (natural ABS dissolved in acetone). The heat will make the slurry film tacky, and the kapton will not ITSELF bond to the ABS print, so worst case you may have to replace the tape on the glass if the print is difficult to remove from the tape. 14:30 - please don't use paper to measure surface to head distance, go get a set of feeler gauges - they're only a few $ from a auto parts or hardware store. Automatic and more modern software is, of course, the gold standard.

ABS isn't a blend, it's a copolymer. Specifically it's a graft copolymer, where they take butadiene (rubber) flake and catalytically polymerise the two other ingredients, introduced as gaseous monomers, onto it. Indeed the properties of the material can be varied in a large range by changing the mixture or even the shape of the graft base flake. This is a spectacularly weird material like that. PETG i believe is a true copolymer, where there are no continuous chunks of a given monomer in the polymer chain, and it can be varied as well fundamentally, but for some reason it's fairly consistent in its properties...

I bought a BL touch sensor for my printer. Only to learn, while modifying the firmware settings, there is an option for "mesh bed levelling". I have found this to be far superior to the automatic sensor, and at a cost of zero dollars. This is regarding a Neptune 2S, similar to Ender 3, and many other brands.

At last someone that goes into the details in a way that I can understand! Now I've got to see of you covered PLA and PETG so I'm "IN" subscribed!

I solved my ABS adhesion problem by turning off my cooling fan, turning my build plate temperature to 0 degrees, upped the nozzle temperature to 230 degrees, and put strips of masking tape over the center portion of my build plate. The ABS sticks to the masking tape just fine and I use a razor blade scraper to peel the tape and print off the build plate, I peel the tape off the bottom of the print and anything that sticks to the print can be sanded off with some fine grit sandpaper. Its just a little more labor involved but my prints come out fine.

and for a bigger parts( fast plate size ) printed is not shrinking , so the edges are not lifting up from plate?first layer thickness to you? or any difference?

In PrusaSlic3r I use the setup that print the center first and the perimeters at the end of the first layer. That prove to help specialy in some big circular prints I made.

Thanks for the run down, you explained perfectly and my prints are sticking nice... turns out my hot end fan was dumpling a ton of air strait down and cooling my prints. Used a piece of tin foil and redirected air flow out the back. Stock Ender 3 pro.. Thanks again my man!! 💪💪

About this Thema, i agree with you. That improve a lot in regards to have warping with abs. I accidentally found another God way to avoid warping and it consists in have a very thin first layer. Almost transparent by reducing the extrusion flow and layer height for the first layer. But you will need a very good leveled bed. Once you can print this such as almost transparent first layer the warping will disappear forever! Maybe 0.05 first layer height. With 50% less extrusion material.
