![]() ![]() Since bed adhesion is an issue with ABS, it’s important that the print bed itself is as clean as possible. Even if they don’t yield perfect results, they should provide a good starting point for tweaking and fine-tuning your printer settings. What we are presenting here are generally accepted good practices when working with ABS. ![]() There’s still a huge variability in the performance of 3D printers and 3D printing filaments that hitting the perfect combination of printing parameters typically still involved a good amount of trial and error. Take note that implementing these measures provides no guarantee that your ABS print will proceed with no issues. The best settings and printing parameters for ABS This isn’t unique with ABS as 3D printing with plastics inherently causes respiratory hazards, but the importance of good ventilation is a lot more pronounced when working with ABS. This isn’t just a matter of the smell being irritating – these fumes can have toxic compounds that can have long-term effects. FumesĪs anyone who has ever worked with ABS will readily tell you, it releases an unpleasant odor when it is heated. Unfortunately, this can no longer be remedied and the print will have to be redone from the beginning. This is the reason that failed ABS prints are typically characterized by corners that “lift off” or “curl” away from the print bed. However, this thermal stress tends to accumulate around sharp corners in the print’s base layer. Ideally, the adhesive forces between the print bed and the base layer will counteract the thermal stress that this contracting effect creates. When a material warps, it contracts across all directions. To identify why ABS exhibits poor bed adhesion, we have to go back to the phenomenon of warping. In fact, ABS has high surface energy which bonds well with adhesives, paints, and other plastics. This isn’t directly a fault of the material itself. The most common manifestation of warping in ABS is the base layer of the print lifting off the print bed, typically at the corners. ![]() If you need your finished print to have accurate dimensions, you’ll have to plan for the effects of warping during the design phase. This is especially pronounced with ABS because of the rapid temperature drop that the material experience once it is extruded and the fact that ABS becomes semi-solid way before it stops contracting. ![]() Warping is a natural consequence of the plastic material shrinking while it cools. While this gives ABS a characteristic heat resistance, it also makes it particularly prone to warping during the 3D printing process. Relative to other 3D printing filaments, ABS is a material that is often described as one that prints at high temperatures. We’ll be taking this strategy in dealing with ABS by highlighting the most serious problems you’re likely to encounter and coming up with pre-emptive solutions. The best way to approach a situation is to know the problems you can potentially be facing. What problems to anticipate with printing with ABS There’s nothing new or exceptionally novel here – this is just a conveniently compiled list for your reference. To help ease the task of overcoming this burden, we have compiled this list of best practices for 3D printing with ABS. It’s often recommended that beginners stick to the more user-friendly PLA and PETG but working with ABS is a rite of passage that everyone needs to go through. Despite this fact, ABS is also notorious as one of the most difficult to deal with. 3D Insider is ad supported and earns money from clicks, commissions from sales, and other ways.Īs one of the toughest yet inexpensive plastics ever developed, ABS is also one of the most heavily used plastics in 3D printing. ![]()
