Printing with ABS

Heatbed with ABS

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.

3D printer PSU holder

Power Supply Unit (PSU) for the 3D printer is usually a large block that floats around the desk and is not connected to the printer. It is usually forgotten to integrate into the design. If you are lucky you can find mods on thingiverse, but I had no luck and had to design one myself.

Build a 3D printer - Part 12: Power supply

12V 30A power supply

After hooking up of all the connections to the RAMPS 1.4 board we will need to provide power to the board. The standard 5V output of the USB connector is only sufficient to power the Arduino and the LCD display, so we will need external power. The minium power that needs to be provided is 12V x 20A (240W). But just to be sure we will use a 12V x 30A (360W) power supply.
