After deciding to build a bartop arcade cabinet I had the option to buy a prebuilt kit or create everything from scratch. I have chosen for the latter as I though that it would give me more freedom in design and in the end more satisfaction.
The most important advantages of ABS are impact resistance and toughness. Lego is made from ABS. It will also not deform in hot water, compared to PLA. On the downside ABS is hard to print. You need very hot printbed (around 110 degrees Celsius) and Kapton tape, so the first layer will stick properly. ABS can also warp and curl. There are also other issues in the Marlin firmware that need some attention.
