This profile is designed for printing with Sunlu ABS 1.75mm filament using OrcaSlicer on enclosed 3D printers. It is tailored for makers and engineers who need reliable, high-quality results when producing small mechanical parts and clips. The settings focus on minimizing layer cracking, ensuring strong layer adhesion, and delivering consistent print quality and strength.
ABS is known for its strength but can be prone to warping and layer separation, especially on small parts. This profile uses a high hotend temperature and a heated bed to promote strong interlayer bonding. Cooling is carefully managed, with the fan limited to 20% after the first five layers, to prevent rapid cooling that can cause cracks. The use of an enclosure is required to maintain a stable environment and further reduce the risk of warping.
Hotend and Bed Temperatures: The hotend is set to 245 °C (250 °C for the first layer) and the bed to 100 °C. These temperatures are optimal for Sunlu ABS, promoting strong layer bonding and reducing warping.
Cooling Fan Control: The part cooling fan is kept off for the first five layers, then limited to a maximum of 20%. This prevents sudden cooling, which can cause layer cracks in ABS, especially on small parts.
Enclosure Requirement: Printing inside an enclosure is essential for ABS to maintain a consistent ambient temperature and prevent drafts, which helps avoid warping and cracking.
Bed Adhesion: A brim is recommended to improve bed adhesion and reduce the risk of corners lifting during printing.
Infill and Walls: The profile uses moderate infill (~40%) and three solid walls, providing a good balance of strength and material efficiency for small functional parts.
