Advanced Raft Configuration in PrusaSlicer 2.7
When working with a high-performance machine like the Prusa i3 MK3S+ or exploring new slicers such as PrusaSlicer 2.7, fine-tuning your raft settings becomes a crucial step for achieving flawless prints. A raft isn't just a basic foundation; it requires precise thermal and speed adjustments to ensure proper bonding. First, it is highly recommended to increase your first layer temperature by 5°C to 10°C. For example, if you normally print eSUN PLA at 205°C, try setting the raft's initial layer to 215°C. This slightly higher temperature helps the molten filament seep into the micro-textures of your PEI sheet, creating an unbreakable bond. Additionally, dropping your first layer print speed to 20 mm/s allows the extruder to lay down the tracks perfectly without tearing them off the bed during rapid travel moves.
Dealing with Difficult Materials and Raft Removal
While standard materials like PLA are forgiving, advanced filaments such as PETG from Overture or Prusament can make raft removal a nightmare due to their incredible layer adhesion. If the raft fuses too strongly to your main part, you need to adjust the Z contact distance. In PrusaSlicer, changing the contact Z distance from the default 0.1 mm to a slightly larger gap like 0.2 mm or 0.25 mm makes a world of difference. It creates a weaker bond between the raft and the model, allowing you to peel it away easily once the print finishes. For those with dual-extruder systems like the Bambu Lab X1 Carbon with an AMS unit, printing the raft with a soluble support filament (like PVA) is the ultimate solution, ensuring zero post-processing effort and a perfectly smooth bottom surface.
