I used to like esun and still use their other colors but the last order I received of black was absolute trash. PETG is always going to be stringy but this was overly stringy. I ordered 2 rolls because I needed them the next day for a job that needed to start ASAP and I didn't have enough black on hand (usually atomic or overture) so rather than have 2 different color blacks I decided to bring in 2 rolls of ESUN for next day and then 2 rolls of overture to have for day to day prints but it wouldn't come in for 3 days. At first I thought it was wet so I dried it out for 5 hours at 65C but it didn't do anything. I ended up lowering temp down to 232c and increased retraction from .8mm to 1mm and worked through the print but I still have an unopened roll sitting here that I just don't want to mess with.maybe this is a one off, their other colors print just fine and I'll continue to buy them but i'll pass on the black for now.Hopefully you know this already but you must use ventilation with ABS filament. Challenging material, it will warp like crazy unless you have a full enclosure. Maybe you can do single, small parts on an open frame printer but there's a lot of heartache waiting there.Cool material though, if you can get it printed in a toasty enclosure. Strong and a bit flexible, the B in ABS is for the butyl element, the rubber gives it its unique quality and impact resistance. It sands nice, paint adheres well, and ABS cement with ABS is the strongest glue joint you can get with 3d printed parts, because it is a solvent and melts the two parts together into one.To get it to stick I've had the best luck using "ABS juice" (abs filament and acetone) on glass at 100C bed temperature. The ABS juice does make an odd, shiny, sometimes papery film layer on the bottom, I often have to hit it with some sand paper.Prints well in an enclosure, but I found that some parts have poor layer adhesion. Most components are fine though. It’s almost as if there are certain parts of the filament that just don’t fuse as well as others. It’s not anywhere close to the worst filaments I’ve tried though, and I would purchase it againThis White ABS filament feels odd to me. It has an odd, kind of chalky, texture and seems brittle after printing. For example, print an object with a brim and then hold the brim in your hand and crumple it. It kind of breaks and crumbles instead of just flexing and bending.Now, the reason I'm writing this review is that, today, I started a long print job on a large item. The total job was going take about 5.5 hours. I started the job in the morning before heading to work as I use OctoPrint to remotely manage my printer. About an hour into the job, I noticed that after the first layer, and about half way into the second layer, it looked like filament was no longer being extruded. I had assumed that the print head had a jam (which is weird for me as it would be the first ever), so I canceled the job and went back to work (hey, I gotta do SOME work at work). When I went home for lunch to examine the printer, I noticed that the filament had been yanked out of the print head. I inspected the filament path and immediately noticed that I couldn't draw any more filament from the spool when pulled on. Upon closer examination of the spool, it became evident that the spool had a cross-over. Somehow my roll of filament, several yards into the spool, had been crossed under another loop. It could only have been done by a human, IMHO, so I'm guessing that some helpful eSun guy had the spool unroll on him so he locked the filament in place under another loop, and then rolled and taped the end of the remaining filament over it. Now I have to wait until I get home tonight to set the printer up again. So, I guess I don't feel confident that there's not another filament lock somewhere further into the spool? That in addition to the aforementioned weird texture of the product makes me think I'll be avoiding this brand in the future.I don’t have a lot of experience with ABS yet on my Ender 3v2. What little I did print, printed fine. Has some adhesion tuning to figure out yet.Very unimpressed with this ABS filament. Diameter is inconsistent which leads to blobs in the walls of prints. No amount of drying changes this. When switching to a known good filament, blobs are gone.I'm getting great results with this filament using an FF Creator Pro. This is the first ABS filament that I have used that has no sign of "elephants foot". 240 degrees hotend temp, 105 bed temp for 1st layer and 95 for the remaining layers. Printing at 50 mm/s with the other speed settings left at the default (Simplify3D). I have used HatchBox ABS in the past and HatchBox does work well, but I'm getting better results with this ESun ABS.The only slight gripe I have is that you do have to babysit the first few layers of the very first print because the spool is filled to the brim, so it's easy for the filament to jump off the spool and wrap itself around the spool holder. This seems to be a general problem for ABS filaments because ABS is lighter than most other filaments, so a roll takes more filament to get to 1KG than PLA or PETG would.I’m printing parts for a Voron printer on my CR-10v2, this filament prints excellent. I’m printing at 240c at the hot end and 100c bed at 60mms and 90% flow rate. Most of what I’m printing is 5-6 walls/top/bottom at 60% or more infill, many filaments I have tried fail/deform at high wall/infill settings. Warping has not been an issue at all printing on a PEI spring steel sheet. The color is actually a “cool grey” (blueish) compared to many other grey filaments that are a warm grey tone. Highly recommend.Have never had any issues when printing with this filament. Gives excellent, consistent quality prints every time.Value-for-money wise I rate it lower because I feel that ALL 3D plastic filaments are overpriced for what you pay/get from them.The eSUN ABS is in my 3D printer 3 times out of 4 when I need a really high quality, low-hassle print job to be completed.ESun continues to produce consistent good quality abs abs+ filament. Used primarily on an enclosed printer.Have not been able to print a lot with this filament yet but when I have done seems to be pretty decent.Unter abs hatte ich mir ein gummiartiges filament vorgestellt. Leider hat dieses Produkt eher die Eigenschaften von pla.Good quality filament and delivered on time
